Boiler Maintenance and Repair 101

Boiler Maintenance and Repair 101

Boilers are a closed vessel in which water is heated. The heated or vaporized fluid exits the boiler for use in various heating applications, such as water heating, central heating, boiler-based power generation, sanitation, and cooking. Boilers are essential in every building because we use heat every day. Whether it’s winter and your house requires heat to warm up your surroundings, or you enjoy cooking and need heat to prepare your meals, we all use heat to some degree in our day-to-day activities. 

Today’s boilers are better than ever because they’re sleeker-looking, produce more heat, and help reduce your energy bills. According to the Department of Energy, modern-day boilers are 98.5% efficient, which means new boilers waste less fuel than boilers from a decade ago. An efficient boiler uses less energy, which lowers your monthly energy bill and reduces your impact on the environment. Even though boilers do so much for us, most homeowners are stumped when it comes to basic boiler maintenance and repairs. Some homeowners don’t know they have to inspect their boiler each month. 

If you’re one of these clueless homeowners, don’t worry, it’s not too late for you to catch up on your boiler’s maintenance. These simple steps to tune-up your boiler adds years of service to your unit, and increases the interval between professional boiler inspections. Continue reading to learn more about keeping your boiler in top shape.

1. Perform a Test Run

The first step to conducting boiler maintenance is to switch your system to determine if it’s in proper working order. Run your boiler for 20-30 minutes and make sure your boiler is doing the following:

  • Producing heat
  • The boiler has an even heat output to the vents and radiator
  • The boiler isn’t leaking
  • Boiler pipes aren’t making unusual noises
  • Wait for your boiler to cool down before you proceed with the rest of the maintenance steps. 

2. Check Your Boiler’s Pressure Readings

Most boilers come with a pressure gauge that usually stays between 12-15 psi. The boiler’s pressure is controlled by the expansion tank and the pressure relief valve. Additionally, boiler systems typically have a set of temperature gauges that monitor a room’s thermostat, boiler water temperature, temperature safety limits, and a circulating pump’s temperature. Check your boiler’s manual to learn all about your boiler’s control settings and troubleshooting signs. 

3. Replace Your Oil Filter

Oil-fired units require annual oil filter replacement. Use the boiler’s oil shut-off valve to turn off your boiler’s oil supply. Look for the oil filter and remove the filter’s housing cover. Replace the old filter and install a new one. Read your boiler’s manual to make this maintenance task safer and easier. 

4. Lubricate Your Circulating Pump

Some boilers perform better after a few drops of pump lubricant, which helps your system’s water circulation and prevents other boiler failures. 

5. Inspect Your Expansion Tank

Check your expansion tank’s water level. A healthy expansion tank should be about half-way full. If your expansion tank is more than half-way full, you’ll need to use a drain valve to return the tank to its natural water level. However, if your expansion tank is overflowing, your tank might have an air leak or needs to be recharged. There’s nothing you can do to fix a troubled expansion tank, and you’ll need to call a professional.

6. Examine Your Water Softener

Unless you live in a city where the water is already soft, you’ll have to soften your boiler’s water now and then. Open your boiler’s brine tank and examine your water’s salt levels. Manually break up any large chunks of salt and rebalance your boiler’s salt and water levels. Clean out your brine tank if it’s dirty. 

7. Install Carbon Monoxide Detectors

A potentially deadly consequence of a malfunctioning boiler system is the emission and build-up of carbon monoxide gas. Make sure you have multiple carbon monoxide systems installed in your home. Perform routine safety checks on all of your detectors and change their batteries each year. 

8. Common Boiler Problems and Repairs

Familiarize yourself with the top three most common boiler problems:

Kettling

Kettling occurs when your boiler produces loud, unpleasant noises that come from the boiler’s heating unit. The only solution is to replace your boiler entirely, which will cost a lot of money. Alternately, you can call a technician to flush out the system for you. 

Leaking

Boiler leaks indicate your boiler is having significant problems, and they’re usually a sign your boiler is corroding. Replace your pressure relief valve and boiler’s pump. 

Lack of Heat

Perhaps the most challenging boiler problem to handle is when the boiler stops producing heat. While the problem might have to do with your boiler’s ignition, there are many potential problems to consider. Some of the issues range from having a broken thermostat to dealing with a fractured pump. Don’t attempt to pinpoint the problem on your own. You’re better off calling a technician instead. 

Providing your boiler with monthly maintenance can keep a host of problems at bay. However, boiler problems sometimes arise without any rhyme or reason, and your only hope is to work with an experienced technician.

How To Fix A Leaking Boiler

How To Fix A Leaking Boiler

A leaking boiler isn’t something you want to experience, and you shouldn’t take it lightly. Leaking boilers are troublesome and result in adverse consequences. An untreated leak usually leads to rusting components, which eventually leads to malfunctioning electrical components within your boiler. As soon as you detect boiler leakage, you must pinpoint and fix the problem quickly to prevent more severe damage. 

Boiler leaks are most common during the winter, and this shouldn’t come as a surprise. Not only is your boiler working overtime in the cold months, but when the temperature drops below zero, standing water in the pipes and inside the boiler can freeze into ice. Moreover, the condensate pipe, which removes the remaining steam and condensation from your boiler, can freeze shut; this prevents your boiler from functioning properly. 

Worst of all, your boiler can go faulty for a multitude of reasons, which could be difficult to detect on your own. Here is a guide to help you identify boiler leakage. Continue reading to find out how you can fix your boiler

Understanding How a Boiler Works

Boilers are water-containing vessels that transfer heat from a fuel source (usually oil, gas, or coal) into steam. The steam is then piped to a point where it can be used to run production equipment, provide heat, to sterilize, to steam clean, among other tasks. There are two main types of boilers: firetube boilers and water-tube boilers. 

Firetube boilers, also known as shell boilers, can produce up to 25,000 pounds of steam per hour. 80 percent of boilers at home are of this configuration. You may have also heard of a packaged boiler, which is a subtype of the firetube boiler. Packaged boilers are shipped complete with fuel-burning equipment, mechanical draft equipment, and automatic controls that are designed to function automatically. It’s especially important to prevent any scale formation when it comes to packaged boilers. 

Watertube boilers are rectangular and contain two or more drums. Separation of steam and water occurs at the top of the drum, whereas the bottom drum serves as a collecting point for sludge. These systems aren’t as standard as firetube boilers, but they are essential when over 100,000 pounds of steam per hour is needed.

Determining Why Your Boiler Is Leaking

Identifying boiler leakage is stressful, but the following reasons might explain why your boiler is malfunctioning. Is your boiler’s pressure too high? If you notice that your system is leaking from the boiler pressure valve, then you ought to check if the pressure is too high. Boiler pressure relief valves are supposed to leak water as a safety protection feature to prevent ruining your other appliances. To check if your valve is suffering from too much pressure, look at the gauge needle on your boiler. The gauge needle should be pointing toward the green section and should be set to around one bar. If the gauge needle is pointing toward the red section, it’s an indication of valve overpressure. A way to solve this problem is to bleed out your boiler to help reduce pressure. 

Another common culprit of water leakage is pipe corrosion. Corrosion is the reversion of metal to its ore form. For example, iron reverts to iron oxide as a result of corrosion. The process of corrosion is a complex electrochemical reaction that can occur in many forms. Boiler leaks can be attributed to corroded pipes in the water tank, which are bound to break down over time. If your pipes only started corroding recently, then a technician can replace your pipes with ease. Unfortunately, if the corrosion is widespread, then you’ll need to replace your entire boiler. 

Fixing Your Leaking Boiler

There are only a handful of steps you can take to try fixing your boiler, and if all else fails, you’ll have to call a professional. Before you consult a technician, try the following:

  • Shut off your water supply.  Do this by turning off the internal stop tap; this keeps the puddle of water from growing.
  • Turn off the heating: If your house depends on central heating, it’s best to switch off the system as well.
  • Drain your system: Since this is a boiler, you can expect some water left inside. To drain the remaining liquid, turn on your tap. Additionally, you may also want to flush all the toilets in your house to speed up the process. Once you notice that no more water is coming out, you’re good to go. 
  • Mop up the water: If the puddle surrounding your boiler has collected too much water, you have to mop it up fast. Don’t let your boiler’s water sit on your floor for days, as this makes your floor slippery and can pose a safety hazard to your children. Sitting water also leads to mold growth, so mop up the water as soon as possible.

choosing HVAC replacement brand

Tactics for Choosing the Right HVAC Replacement Brand

Within the world of major HVAC components, there are a number of well-known brands out there. From Honeywell and Lennox to Rheem and Carrier plus several others, you have a multitude of brand options when it comes to your next furnace, air conditioner, water heater or other HVAC materials.

At Roberts Mechanical, we’re here to help with all air conditioning and furnace repair services, plus numerous other HVAC contractor areas. We also offer high-quality replacement services for each of your major components, generally providing you with several brand options when you’re in need of an upgrade. Let’s go over several factors that will help you differentiate between brands and make the right choice for your home.

Utilize HVAC Pro Expertise

For starters, even if you’re a handy and experienced homeowner, we highly advise against buying major HVAC equipment on your own and without the assistance of licensed HVAC pros. There are a couple reasons for this, but the most important directly affects your bottom line: Many reputable HVAC companies won’t install new equipment unless it’s purchased through them.

In addition, HVAC professionals simply have an eye for factors that you won’t. They’ll prevent you from safety hazard risks that take place due to improperly-sized materials, plus the utility bill increases that often come from this same area. Most HVAC quotes will include several brand options at different pricing ranges.

Established Brands

Within the HVAC world, there’s no single brand that’s considered superior to the others. Rather, there are several established brands to choose from – and in this case, experience and reputation are important, as these areas often dictate the quality of warranties and materials. Specifically, HVAC components are meant to last decades; if you choose a lesser brand from a manufacturer that might not even be around in 10 years, what are you going to do if it comes time to claim a warranty?

Brands and Reputation

Within the major brands, however, there are often differentiating factors that will lead you to your final choice. Our pros will tell you which areas certain brands are known for strengths or weaknesses in, and you can match these with your needs and desires in the home.

Warranties and Other Perks

Finally, a major differentiator for many homeowners when choosing between brands is the various perks they offer. One major area here is the warranty, which you should go over in detail and ensure you understand fully for each brand. Other perks may include financing offers, money-back incentives or similar tactics aimed at improving your purchasing experience while increasing the value you receive.

signs HVAC wear commercial buildings

Telltale Signs of HVAC Wear Issues in Commercial Buildings

If you’re the owner or manager of a commercial building, particularly one where employees work each day, maintaining comfortable air quality and temperature is an important task. Not only are uncomfortable employees less productive, lacking HVAC services may lead to health and liability risks in some cases.

At Roberts Mechanical, we’ve been providing HVAC services like air conditioning repair and many others for over 30 years. One of the top factors in maintaining commercial HVAC systems is understanding when certain components might be nearing the end of their lifespan and require replacement – here are some telltale signs this is the case within your building.

Increased Complaints

Whether you manage the facilities or employ a facilities management team, you may begin to notice more complaints rolling in from your employees. These will generally be regarding the indoor temperature and its swings, but it could also be due to air quality or questions about the allergen content in the air.

Rising Energy Bills

Have you begun to notice that your energy bills are rising each month compared to the previous year despite no major changes in components or temperature needs? This is often a red flag that components within the HVAC system are wearing down, forcing the system to work harder just to provide the same level of comfort as before.

Employee Sickness

If you’ve noticed a higher-than-usual number of employees getting sick recently, you should first check for other causes. Maybe a contagious employee came into work for several days straight and infected several others, for instance.

But if you can’t locate any other cause, and if the issue persists long enough to clearly not just be randomness, the HVAC system could be to blame. Certain worn-down equipment will negatively impact air quality, such as filters that aren’t changed often enough and may lead to respiratory concerns for some people.

Temperature or Moisture Concerns

Are many of the complaints making their way to you regarding different temperatures in varying areas of the building, often with wild levels of variance? What about moisture being found in areas it shouldn’t? These are generally ventilation issues, which can also have a significant impact on air quality and health. If you are receiving these complaints, check all your ducts, vents, registers and other areas related to ventilation.

Odors or Noises

Finally, you or employees may begin to notice foul odors, particularly when near HVAC vents or other airflow areas. These odors may be similar to spoiled eggs, or could be slightly different.

In other situations, you may actually hear strange noises coming from the HVAC system. In either of these cases, these are clear signs that something is wrong and you should consider an HVAC inspection.

types details hvac warranties

Types and Details Associated With HVAC Warranties

For many of the high-value items we purchase and use in our daily lives, warranties will be part of the purchase agreement. This is the case for numerous product areas, and is an important factor when purchasing certain pieces of HVAC equipment.

At Roberts Mechanical, we’re happy to help you understand any and all warranties offered for our heating or air conditioning installation services. There are actually a few different types to help protect you from potential issues with items like your furnace, air conditioner, water heater and others – let’s look at each of these warranty types, plus some important details you should be sure to confirm anytime you’re purchasing these components.

Types of HVAC Warranties

Here are at least four kinds of warranties you may be offered from a few different sources when purchasing HVAC equipment. They are as follows:

  • Manufacturer guarantee: In reality this is less of a specific warranty, though it can function that way practically. This is simply a promise made by the manufacturer of a given piece of equipment that it was made properly and should function well – many such guarantees are simply implied rather than actually written. If defective materials are installed, however, you should be able to get replacements free of charge.
  • Manufacturer warranty: Separate from a manufacturer guarantee is a manufacturer warranty, which covers specific parts or products over a given period of time. If an AC condenser that’s covered by this warranty fails within the allowed time period, for instance, it will be replaced for no charge.
  • Labor warranty: Some HVAC companies offer labor warranties. These ensure that in a situation where the installation of a given product was performed incorrectly, causing defective issues, proper installation can be done instead without a charge to you.
  • Extended warranty: Possibly available from both a manufacturer or installer, extended warranties are generally those that come with extra costs and cover additional areas above and beyond other warranties.

Confirming Important Warranty Details

No two warranties are exactly the same, and they will vary pretty widely between both manufacturers and HVAC installers. When purchasing any HVAC materials, be sure to consider all of the following areas to be sure you’re getting the warranty you need:

  • Transfer: If you sell your home during the warranty period for a given HVAC component, will the warranty transfer to the new owner? This could play a big role in property value.
  • “Lifetime” warranties: When you see this term, you have to clarify how long “lifetime” is actually referring to here. Is it your lifetime? The part’s lifetime? The home’s lifetime? Ask for specifics and ensure they are followed.
  • Invalidation: Find out if there are any practices that will cause your warranty to be voided or invalidated in any way. These usually refer to attempting HVAC repairs you are not licensed for, but may include other areas as well.
  • Process: Make sure you understand how to access your warranty in case of something going wrong that’s covered by it.

hvac tips property landlords

HVAC Tips and Advice for Property Landlords

At Roberts Mechanical, we’re proud to provide heating and air conditioning services for homes and individuals in various situations. One such situation is for landlords who are renting their properties out to tenants – while it’s the tenants who live in the home and are responsible for certain important day-to-day HVAC maintenance areas, it’s you as a landlord who is ultimately responsible for costs and long-term upkeep here.

Regardless of whether you’re landlord over a single Utah property or several, we can help you keep your HVAC systems and air quality in great shape. Let’s go over a few basic tips we can offer landlords on staying diligent with the HVAC system without interrupting privacy rights of tenants.

Changing Filters

Whether it’s listed as part of your rental agreement or just understood between you and your tenants, you have to ensure HVAC filters are changed at the proper intervals so they don’t accumulate dust and stop functioning well. Most filters need to be changed every one to two months depending on the filter and the dust levels in your home.

As a landlord, it is generally your responsibility to provide these filters. You should ensure that the tenants have at least one or two extra on hand at all times so they can change them as needed.

Standard Maintenance

Particularly for homes where you aren’t around every day to maintain the system, you should have bi-annual inspections and tune-ups done by our professionals. We’ll go through the entire system and check for any buildups or worn down components, making sure everything is both safe and functional. As an added bonus, we can often spot the signs of lazy or improper HVAC management by your tenants, allowing you to regulate that area if harm is being done to your system.

Replacement and Inspection

While you don’t need to have every date memorized, you should be keeping track of when major components in your HVAC system, such as the air conditioner or furnace, are nearing the end of their lifespan. This generally happens around the 15-year mark in most cases, though this can vary depending on how well the system is maintained (our yearly inspections can provide good information on how close various components are to wearing down).

Once the time for replacements does eventually come, be as involved as you can in the selection and inspection process. Our pros are happy to help inspect and install all components for you.

Vacant Properties

During periods where any of your properties sits vacant, you can make a few HVAC adjustments to both maintain the property and save money. You can set the thermostat lower in winter – you have to leave it on around 50 to 55 degrees to prevent frozen pipes, but that’s it – and turn it off completely in winter. If the property sits unused for several months consecutively, however, it’s good to return periodically and ensure there aren’t any humidity or mold issues beginning to form.

understanding preventing furnace short cycling

Understanding and Preventing Furnace Short Cycling

Particularly during a long winter season like the one Utah is currently undergoing, the furnace is one of the most important pieces of HVAC equipment in the home. In charge of distributing warm air throughout every room, the furnace requires some basic areas of upkeep to ensure it’s working properly.

At Roberts Mechanical, we can provide a full range of furnace repair services for Orem and surrounding areas. One of the most common issues we’re called out to assist with is known as short cycling – what is this, and what are some of the primary factors that cause it? Let’s look at the basics here, plus how you can prevent these risks.

 

Defining Short Cycling

Simply, short cycling is a condition that describes when the furnace turns on and off repeatedly much more often than a standard furnace would. In many cases, it means the furnace spends the entire day starting and stopping in short bursts, which puts a huge amount of stress on several of its mechanical components and wears them down faster.

In addition, short cycling can lead to big issues with your in-home heating. It can cause uneven amounts of heat in various parts of the home, plus often raises utility bills by significant amounts. For this reason, it’s good to know the common causes of short cycling and how to prevent them, which we’ll discuss in our next section.

Causes and Prevention Areas for Short Cycling

Here are some of the primary factors that lead to short cycling, plus how to avoid any such risks:

  • Size of furnace: One common mistake homeowners make is buying a new furnace that’s too large for their space, assuming it will just do the job even better. This isn’t the case – an oversized furnace will actually heat your space too quickly, leading to long periods where it turns off earlier than required. To prevent this, always have HVAC professionals like ours assist you with furnace installation.
  • Insulation problems: Not only does your furnace need to be able to pump warm air into the home, the structure needs to be able to retain it. If you’re dealing with poor insulation, or perhaps issues of leaks by your windows and doors, new heat could be leaving the home quickly and forcing the furnace to start up again too quickly. Check these areas regularly to ensure this doesn’t happen.
  • Clogged filter: Clogged furnace filters can stop air from passing over the heat exchanger, which overheats the furnace and shuts it down. Furnace filters should be changed at least once every couple months, or more often in some cases.
  • Thermostat concerns: Malfunctioning thermostats may cause the furnace to short cycle for a few different reasons, sometimes due to poor battery life. In other cases, thermostats located too close to a heat source may register too much heat from this source and turn off the furnace even when the entire home isn’t properly heated. If you’re changing out your thermostat, work with our pros to ensure it’s located properly.

window labels hvac efficiency

What Window Labels Say About HVAC Efficiency

When it comes to staying warm in the winter and cool in the summer, we tend to think predominantly about our HVAC system – the furnace and AC, vents, ductwork and all other related components. This is natural, as these elements are the primary pieces of equipment that dictate your home’s heating and cooling.

At Roberts Mechanical, however, we’re here to tell you about another home component that’s vital for winter heating and summer cooling: Your windows. Windows are among the primary holders of air in your home, stopping it from escaping to the outdoors and forcing your furnace or AC to work harder to pump more back in – costing you money in the process.

With this in mind, let’s look at some of the important window labels you need to know about. Whether you’re shopping for new windows or just looking to assess your current ones, here are the important facts to know about what these say about window efficiency.
/>

Manufacturer Label

There will be multiple panels on a given window label, each telling you different things. One such panel will be from the manufacturer of the window, and it will state the manufacturer name plus a model number for that design. Just below this will be specific product features, potentially including:

  • Frame materials: Generally wood, aluminum, vinyl, steel, or fiberglass composite
  • Number of panes: Single-pane, double-pan, triple-pane
  • For multi-pane windows, the type of gas that fills the gap (generally krypton or argon) will also be listed
  • Glazing style
  • Low-E: A specific glass treatment that limits the impact UV rays can have on your carpets or furniture – without this, these materials may fade over time due to UV rays

NFRC Label

Once you’ve moved past the basic window information, you’ll also notice four or five numbers in bold on the label. This is the NFRC label, with data calculated by the National Fenestration Rating Council – this group tests windows, doors and other openings and certifies them based on their quality. Important elements of the NFRC evaluation include:

  • U-Factor: How well windows keep heat in the home – lower numbers mean better energy efficiency, while higher numbers are worse.
  • Visible transmittance: How much light a window lets in – higher numbers mean more light.
  • Solar heat gain coefficient: How effectively windows block heat from outside that isn’t desired inside. The lower the number, the more efficient.
  • Air leakage: How much air of any kind the window lets in. Again, lower numbers are better here.
  • Condensation rating: Only found on some NFRC label, this rating tells how well a window resists condensation, with a higher number equaling better resistance.

Energy Star Logo

You may also see the Environmental Protection Agency’s Energy Star logo on your window, which means it’s highly efficient for your area. There’s no single set of criteria here – certain windows are designed for specific climates, so they’re divided into smaller regions and then assessed based on NFRC measurements for U-Factor and solar gain coefficient.

basics preparation door blower test

Basics and Preparation for Door Blower Air Test

If you’ve noticed your home’s heating bill going up compared to where it was at this time a year ago, you could be dealing with air leaks somewhere in the house. These are often very difficult to spot with the naked eye, but they could be leading to significant energy losses that raise your bill in a major way.

At Roberts Mechanical, our HVAC and heating services include helping homeowners identify these kinds of air leaks when they can’t do so on their own. We use a few different instruments and tests here, depending on your situation. One common test that’s often used across the HVAC world is called the door blower test – what is this, and how should you go about preparing for it if you’re having one done?

Door Blower Test Basics

Door blower tests are part of many home energy audits, with the goal of locating drafts and air leaks and determining how airtight the home is. They use a temporary barrier that our technicians will bring to your home and place on one of your exterior – this barrier has a fan that runs at about 10 or 15 mph, removing air from the home and reducing the indoor air pressure. In addition, the barrier has various instruments to provide data on airflow within the structure.

When the test begins, your technician will turn on the barrier fan. When the home is fully depressurized, the basic effects of physics will kick in: Higher pressure outside than inside will cause air to flow in through any small cracks or openings in your home. Your technician will walk through each area of the home with a tool known as a smoke pencil, which emits odorless smoke and allows them to track the areas where airflow is taking place. Increased airflow from the leak will disrupt the smooth smoke, and your technician will be able to identify the leak and address it.

Preparation Tips

If you’re considering a door blower test for your home or building, there are a few basic preparation steps to take before it’s performed:

  • Batten things down: 10 to 15 mph airflow won’t be enough to ruin any of the elements of your home, but it could ruffle up some things and increase your clutter. Before the test takes place, just take the time to close all windows and other openings so things like paper, fireplace ashes or dust don’t go flying everywhere.
  • Open vs closed: All doors, windows, dampers and openings have to be closed to the exterior for this test. However, any interior doors – plus chests, cabinets and other passageways where air can make it through – should be opened so air can flow as freely as possible within the home.
  • Appliances: Any appliances with a pilot light, including the oven, should be disabled so no sparks or flames are at risk. Our technicians can tell you about which items you’ll need to power down for this test.

For more on the door blower test, or to learn about any of our HVAC services, speak to the pros at Roberts Mechanical today.

dusty home hvac system

Dusty Home and Your HVAC System

If you’ve lived in Utah for a while, chances are you’ve noticed some dust in your daily life from time to time. As one of the drier states in the country, mostly made up of desert land, Utah has high quantities of dust buildup and related issues.

At Roberts Mechanical, we’re here to help if these dust issues make their way into your home. Dust can make its way into the heating and cooling systems of your home and, if unchecked, can lead to a loss of efficiency from your HVAC system and potentially even health concerns for occupants of the home. Here are three common factors that contribute to the presence of dust in your home, plus how you can troubleshoot each of these to avoid these issues.

Air Filter

The first place to check if you’re noticing too much dust in your home is the filter in your furnace. You should regularly be checking on these anyway – most filters should be inspected and replaced around once a month, or sometimes even more often if you have a high-dust home or pets that shed.

The goal of the filter is to act as a trap for dust and numerous other potential contaminants. The higher the filter MERV rating, the finer the particles it will pick up. But over time, even the highest-rated filters become clogged and lose their inability to perform their function efficiently. Often the simplest solution to a dusty home is changing a filter that badly needs it.

Humidity

One of the primary reasons dust is so prominent in Utah is due to the dry climate, which allows dust to flow freely and travel very quickly through your HVAC systems. While people who live in wetter climates may still have dust issues in some cases, their dust tends to settle faster and be trapped in filters more easily due to the moisture in the air.

Luckily, there are simple tools out there to help you increase this moisture content even in a dry state like Utah. Consider purchasing a humidifier for dusty rooms in your home, or even a whole-home humidifier if the issue persists across the whole house. Whole-home humidifiers are also excellent for protecting wood furniture that can wear down over time.

Leaking Ductwork

If your home is adequately humidified and your filter has recently been changed, the next-most likely source of dust is a leak in your ductwork. There are various reasons for small cracks or gaps developing in ducts, from basic aging to possible poor installation. Once these develop, they allow dust to make its way into your breathing air before contacting the filter at all.

To check for these leaks, look for a buildup of dust near your vents or in their fins. If you still aren’t sure, try turning the lights out and using a flashlight to identify the flow of dust particles in the air – following this flow can guide you to where the leak is. If you find a small leak, duct tape usually does the trick for patching it. If it’s larger, you might want to call our technicians.
