About Stewart Heating And Refrigeration

Calling an HVAC company doesn't have to be stressful, and after three decades in this area, we have worked hard to make sure it isn't. We started in Eagle Mountain in 1995 and have been building our reputation here one job at a time ever since. Utah County throws a lot at a heating and cooling system. Winters at this elevation get genuinely cold, summers push temperatures well into the 90s, and the wide swing between seasons means your equipment works hard year-round.

We live and work in this community, and our work shows it. Homeowners, landlords, and business owners across Utah County have trusted us with their systems for years, and a large share of our new customers find us because a neighbor passed along our name. That kind of word of mouth does not happen by accident. It happens because we do the job right the first time and stand behind it.

Residential and Commercial HVAC Services

Some homes need a full system replacement. Others just need a tune-up. Either way, we handle it. We work with single-family homeowners, rental property owners, property managers, small businesses, and commercial building operators across Eagle Mountain and the surrounding Utah County communities. Every customer gets the same honest service and transparent pricing with no hidden fees on any HVAC job.

Residential HVAC. Commercial HVAC. One number for both.

Everyday Heating and Cooling Work

Whether your air conditioner stopped cooling, your furnace is blowing cold air, or you just want to make sure your system is ready for the next season, we cover it all. Our everyday services include:

  • AC repair and service
  • Furnace repair and heating service
  • Heat pump repair and installation
  • Mini-split and ductless system installation
  • Full HVAC system installation and replacement
  • Thermostat and smart-control installation
  • Ductwork repair and sealing
  • Indoor air quality and air filtration
  • Seasonal maintenance and tune-ups
  • Emergency no-heat and no-cool service

Commercial Heating and Cooling

Property managers and commercial clients have different needs than a single homeowner, and we understand that. We work on commercial buildings, multi-unit properties, and small business spaces throughout Utah County. Whether you need a rooftop unit repaired, a commercial system replaced, or a maintenance schedule set up for multiple properties, we can handle the scope. Pick up the phone and we'll handle the system.

Eagle Mountain AC Repair and Seasonal Cooling Service

If you're not sure your system can keep up, Eagle Mountain summers will answer that question fast. Temperatures regularly climb into the mid-to-upper 90s, and a central air system that was limping through spring will not survive a July heat wave. We diagnose and repair air conditioning problems quickly, from refrigerant leaks and compressor issues to condenser coil buildup and evaporator problems that cause warm air or poor airflow.

We also handle full AC replacements when a repair no longer makes financial sense, and we install new central air systems in homes and commercial spaces that are upgrading their setup. Before any cooling season, a tune-up gives your system a full inspection, a cleaning, and a performance check so you are not caught off guard when the heat arrives. We'll service the system and clean up after.

Furnace Repair and Heating Service

Utah County winters are not mild. At Eagle Mountain's elevation, temperatures drop hard and stay cold for months. A furnace that fails in January is not an inconvenience; it is an emergency. We take no-heat calls seriously and respond promptly because we know what a cold house means for a family or a business.

We diagnose and repair gas furnaces, handle air handler and blower service, and replace systems that have reached the end of their useful life. When a furnace is aging and repairs are adding up, we give honest recommendations on repair versus replacement, never an upsell. We tell you what the system actually needs, explain the options clearly, and let you make the call. Call today and we'll set up your appointment.

Heat Pumps, Mini-Splits, and Ductless Systems

The sooner you call, the sooner your comfort is back, and that is especially true when a heat pump goes down. Heat pumps are a strong fit for the Utah County climate because they handle both heating and cooling from a single system. Modern cold-climate heat pumps perform well even at the lower temperatures Eagle Mountain sees in winter, and the efficiency gains over a traditional furnace-and-AC setup are real.

We install, service, and replace heat pumps and mini-split ductless systems for homeowners and commercial clients alike. If you have a room addition, a garage, or a space that your existing ductwork doesn't reach, a ductless mini-split is often the cleanest solution. Let us handle the install and the permits.

Ductwork, Thermostats, and Indoor Air Quality

Ductwork Repair and Sealing

Leaking or poorly sealed ductwork is one of the most common causes of uneven temperatures and high energy bills. If one room is always too hot or too cold, or your system runs constantly without ever catching up, the ducts are often the first place to look. We inspect, repair, seal, and replace ductwork in residential and commercial properties throughout the area. Fixing the ducts is sometimes the single most effective thing you can do for system performance.

Thermostat and Smart-Control Installation

An old thermostat can undermine even a well-maintained system. We install programmable thermostats, smart thermostats, and zoning controls that give you better command over your home's comfort and energy use. Whether your current thermostat has stopped working or you want to upgrade to a system you can control from your phone, we handle the installation cleanly and make sure everything communicates correctly with your HVAC equipment.

Indoor Air Quality and Air Filtration

Utah is a dry climate, and Eagle Mountain homes in winter can drop to humidity levels that dry out woodwork, irritate airways, and make a cold house feel even colder. We install whole-home humidifiers that work with your existing HVAC system to maintain comfortable indoor humidity all winter. We also install whole-home air purifiers and advanced filtration systems for households that want cleaner air at every vent. Call today and we'll set up your appointment.

Emergency and Same-Day HVAC Service

The sooner you call, the sooner your comfort is back. When the heat goes out on a January night or the AC fails during a summer heat wave, waiting a week for a technician is not an option. We offer same-day scheduling and respond to HVAC emergencies around the clock because breakdowns don't follow business hours.

Qualified HVAC technicians are dispatched to your location, ready to diagnose the problem and get your system running again. We keep our trucks stocked so that most repairs can be completed on the first visit. Whether it's a furnace that won't fire, an air conditioner that quit overnight, or a heat pump throwing an error code, we show up and we handle it.

Transparent Pricing on Every HVAC Job

Nobody wants to approve a repair and then get hit with charges they didn't expect. Before any work begins, we walk you through what we found, what it takes to fix it, and what it will cost. That is true for a simple repair, a full system replacement, a maintenance visit, or a new installation. Transparent pricing with no hidden fees on any HVAC job is how we operate, and it is how we have kept customers coming back for 31 years.

You will know what you are agreeing to before a technician picks up a tool. If anything changes mid-job, we tell you before we proceed. Call today and we'll set up your appointment.

Seasonal Maintenance and HVAC Tune-Ups

Some homes need a full system replacement. Others just need a tune-up. A seasonal tune-up is the most straightforward way to avoid a breakdown at the worst possible time. Before summer, we check your cooling system, clean the components that collect buildup, test refrigerant levels, and confirm the system is ready to handle the heat. Before winter, we run through your furnace or heat pump, inspect the heat exchanger, test ignition and controls, and verify that everything is operating safely and efficiently.

Regular maintenance extends equipment life, keeps energy bills lower, and catches small problems before they become expensive failures. We'll service the system and clean up after.

Full HVAC System Installation and Replacement

When a system has reached the end of its life, or when a new construction project needs a full HVAC build-out, we handle the entire job. We size equipment correctly for the space, coordinate the installation from start to finish, and make sure everything is working before we leave. This applies to homeowners replacing a 20-year-old furnace and air conditioner, and equally to commercial clients upgrading a building's heating and cooling infrastructure.

Work performed by qualified HVAC technicians, done to code, and priced fairly. Qualified technicians. Code-compliant work. Fair rates.

We have been serving Eagle Mountain and the surrounding Utah County communities since 1995, which puts us at more than 30 years of local heating-and-cooling work. We started here and have built our business one job at a time in the same area ever since.

We work with single-family homeowners, landlords, rental property owners, property managers, small business owners, and commercial building operators throughout Utah County. Whether you own one home or manage a portfolio of properties, we handle the same range of heating-and-cooling work for every customer type.

We serve Eagle Mountain and the surrounding Utah County communities, including Saratoga Springs, Lehi, Cedar Hills, American Fork, Highland, and Herriman. If you are not sure whether you are in our service area, call (385) 263-3965 and we will let you know.

Our technicians are trained on the full range of residential and commercial HVAC systems and know the conditions that Eagle Mountain homes and buildings face across the seasons. They show up prepared, explain what they find, and do not leave until the work is done right and the customer understands what was completed.

Yes. When a job requires a permit, we pull it and coordinate the inspection so you do not have to manage that separately. This applies to full system installations, replacements, and other work where Utah County requires a permit before the job can be completed.

We handle both sides of the system from the same service call, which keeps things simpler for the customer. If a full replacement involves both a furnace and an air conditioner, or a heat pump that handles both functions, we coordinate the whole job rather than scheduling separate visits for each component.

Your Top Questions Answered

How do I know if my furnace needs repair or full replacement?

Age, repair history, and performance are the three things we look at. If a furnace is under 15 years old and has been maintained, a repair often makes sense. If it is older, has needed multiple repairs in recent seasons, or is struggling to hold temperature even when it runs, replacement usually becomes the better financial decision. We assess the system and give you a straight answer on which direction makes more sense for your situation.

What causes a system to stop heating or cooling properly?

The most common causes are a dirty filter restricting airflow, a refrigerant issue, a failed igniter or control component, or a problem with the blower motor. In some cases the issue is a duct leak that is sending conditioned air somewhere it should not go. We diagnose the system when we arrive and explain what we find before any work starts.

How often should I schedule maintenance or a tune-up?

Once a year at minimum, and twice a year if you are running both heating and cooling hard. In Eagle Mountain's climate, a spring AC tune-up before summer and a fall furnace tune-up before winter is the schedule most homeowners find most useful. Regular maintenance keeps efficiency up and reduces the chance of a breakdown at the worst possible time.

Same-Day and Emergency Availability

We offer same-day service and after-hours response for urgent situations. When your system goes down, we dispatch promptly so you are not left waiting through a cold Utah County night or a summer heat stretch.

Is HVAC installation and replacement work permitted and inspected?

Yes. Installation and replacement work in Utah County requires permits, and we handle that process for you. Permitted work is inspected to code, which protects you when it comes time to sell the property and ensures the system is installed the way it should be.

Why is one room in my home always hotter or colder than the rest?

Uneven temperatures usually point to a duct issue, an airflow imbalance, or equipment that is not sized correctly for the layout of the home. A duct leak in a specific branch, a damper that is stuck, or a return air problem can all cause one area to feel different from the rest of the house. We can inspect the system and identify where the imbalance is coming from.

What do strange noises from my HVAC unit usually mean?

Banging or clanking often points to a loose or failing mechanical component. A high-pitched squeal can indicate a blower motor bearing or belt issue. Clicking at startup or shutdown is sometimes normal, but repeated clicking can signal a control or ignition problem. If the noise is new or getting louder, it is worth calling us before the problem gets worse.

Transparent Upfront Pricing

We provide a clear estimate before any work begins and we stand behind it. Transparent pricing with no hidden fees applies to every HVAC job we take on, residential or commercial.

Is a heat pump a practical choice for Eagle Mountain winters?

Modern cold-climate heat pumps are rated to operate at temperatures down to roughly -15 degrees Fahrenheit, which covers the coldest conditions Eagle Mountain typically sees. They handle both heating and cooling from a single system, which works well in Utah County's four-season pattern. The key is proper sizing and installation; an undersized or incorrectly installed system will not perform the way the technology is capable of.

What does a seasonal tune-up actually cover?

A tune-up is a thorough inspection and cleaning of the system. On the cooling side, that includes checking refrigerant levels, cleaning coils, inspecting the condenser, and testing airflow and controls. On the heating side, it includes inspecting the heat exchanger, cleaning the burner assembly, checking the ignition system, and verifying that safety controls are functioning. We document what we find so you have a clear picture of where the system stands.

Work Performed by Qualified HVAC Technicians

Every service call, tune-up, and installation is handled by trained technicians who know these systems and the demands Eagle Mountain's climate puts on them.

How does a whole-home humidifier differ from a portable unit?

A whole-home humidifier integrates directly with your existing HVAC system and maintains consistent indoor humidity automatically throughout the house. A portable unit only treats the room it is in and requires manual refilling. In Eagle Mountain's dry winter climate, a whole-home system is a more practical and consistent solution for households that deal with dry skin, static, or respiratory irritation through the heating season.

Do I need to be home when the technician arrives?

For most service calls and installations, yes. We need access to the system and we will walk you through what we found and what was done before we leave. If you manage a rental property and cannot be on site, we can coordinate with a tenant or property contact as long as someone with access is available when we arrive.

How does your pricing and estimate process work?

For most repairs, we schedule a diagnostic visit to assess the system before quoting the full scope of work. For installations and replacements, we can often give you a solid range over the phone and confirm the final number once we have looked at the existing setup. We provide an estimate before any work starts and stick to it. If something unexpected comes up mid-job, we tell you before we proceed.

Every home and every system is a little different; call us and we will walk you through the right service for your situation and get you scheduled.
