How can we help?

Furnace Service in Commerce City, CO

When temperatures drop across Commerce City, CO, a reliable furnace is not a luxury but a necessity. At Gustafson Heating & Air Conditioning, we understand how critical consistent heating performance is for your home or business. Since 1971, we have delivered quality customer service, reliability, and expertise in heating, cooling, and ventilation to our residential and commercial clients. Our commitment to furnace service means that every technician we send to your door arrives with deep knowledge, professional-grade tools, and a genuine dedication to keeping your system running at peak efficiency throughout the harshest Colorado winters.

Commerce City experiences wide temperature swings, with winter lows frequently dipping below freezing for extended periods. This kind of sustained cold puts enormous stress on heating equipment. Without regular heater service, even the most robust furnace can develop issues ranging from minor inefficiencies to complete system failures. We work with homeowners and businesses throughout the area to ensure that furnaces receive the proactive attention they need before small problems escalate into expensive emergencies.

Our Comprehensive Furnace Service Process

A thorough furnace service visit involves far more than simply checking whether the unit turns on. Our highly trained technicians follow a detailed, multi-point inspection protocol designed to evaluate every critical component of your heating system. This methodical approach allows us to catch developing issues early, extend equipment lifespan, and optimize energy consumption. As a Rheem Team Top 10 Contractor in the United States, we hold ourselves to the highest industry standards in every service call we perform.

During a standard furnace service appointment, our technicians assess the following areas:

  • Heat exchanger integrity — We inspect for cracks or corrosion that could lead to carbon monoxide leaks, which represent one of the most serious safety hazards in any home
  • Burner assembly and ignition system — Dirty or misaligned burners reduce efficiency and can cause uneven heating throughout your property
  • Blower motor and airflow — Restricted airflow forces your system to work harder, increasing utility costs and accelerating wear on internal components
  • Thermostat calibration — Even minor calibration drift can cause temperature inconsistencies and unnecessary cycling
  • Electrical connections and safety controls — Loose wiring and faulty limit switches create both performance and safety risks

Each of these inspection points contributes to a complete picture of your furnace’s health. After the evaluation, we provide transparent findings and customized solutions to fit your budget, ensuring you can make informed decisions about repairs, adjustments, or future replacement planning.

Why Regular Heater Service Matters

According to the U.S. Department of Energy, heating accounts for approximately 29 percent of a typical household’s energy bill, making it the single largest energy expense in most American homes. Regular furnace service directly impacts this figure by ensuring your system operates at its designed efficiency rating. A neglected furnace can lose between one and two percent of its efficiency each year, meaning that a system running without maintenance for five years could be wasting ten percent or more of the energy it consumes.

Beyond energy savings, consistent heater service dramatically reduces the likelihood of unexpected breakdowns. Most emergency furnace failures we respond to could have been prevented with routine maintenance. Serving our customers in Highlands Ranch, Englewood, and surrounding areas for more than 45 years has given us extensive insight into common failure patterns, seasonal stress points, and the specific maintenance steps that keep furnaces running reliably through Colorado winters.

Residential and Commercial Furnace Service

Our furnace service capabilities extend across both residential and commercial applications. Homeowners in Commerce City depend on us for annual tune-ups, safety inspections, and performance optimization. Commercial clients rely on our HVAC team for more complex systems that may include rooftop units, multi-zone configurations, and high-capacity equipment serving warehouses, retail spaces, and office buildings.

Commercial furnace service demands particular expertise because system downtime can impact employee productivity, customer comfort, and even inventory protection in temperature-sensitive environments. We coordinate service schedules to minimize disruption and ensure that commercial heating systems meet local code requirements and manufacturer specifications.

Scheduling Your Furnace Service Appointment

The ideal time to schedule furnace service is during early fall, before the heating season begins in earnest. However, at Gustafson Heating & Air Conditioning, we provide furnace service year-round because heating problems do not follow a convenient schedule. Our responsive support staff makes scheduling straightforward, and we work to accommodate your timeline whether you need a routine maintenance visit or an urgent diagnostic evaluation.

Investing in professional furnace service protects your comfort, your safety, and your wallet. Contact us today to schedule your next appointment and experience the difference that decades of dedicated heating expertise can make for your Commerce City property.

WOW, what a great job Gustafson Heating and Air Conditioning did for my wife and I. They were professional, fast, and way less expensive than the others we looked into. We really appreciate what they did. It was in the winter when our furnace broke down and they replaced it immediately. They left our home clean and warm and we will appreciate the cool air this coming summer. THANK YOU Mike and your team!

Kristina C.

I received a number of quotes to install a whole home humidifier. Gustafson was amazing from start to finish. I was able to handle everything over the phone without needing an additional in-person quote with a number of upcharges. I spoke to a gentleman who walked me through options by seeing pictures of my setup and was extremely knowledgable on what was necessary to ensure I was getting the correct humidifier for my home. The pricing was extremely competitive compared to the others and was not full of hidden charges. When I called, they were able to get an appointment set up within a week. The service tech was on time, courteous, cleaned up after himself, and walked me through the whole setup.

Svein R.

I got three quotes for a heat pump and gas furnace back-up. Gustafson’s was the most competitive. In addition, Mike McCarthy was, and is, a gem; very knowledgeable and responsive. The other Gustafson employees on the job were courteous and professional. I am very pleased with the equipment and the installation, which was a difficult one. I highly recommend Gustafson!

Meagan P.

Gustafson installed our HVAC system in 2019 and have been so great with service! They’re honest and back up their work. Recently our A/C wasn’t cooling to the set temp. Todd was so kind & diligent in teaching us what to do as homeowners, but also servicing/cleaning the mechanics and we’re back to a nice, cool home just in time for higher temperatures!

Scott H.

Purchased a mini-split (AC / Heat Pump) unsure if I’d be able to install it or not. I installed most of it myself but there were a few technical procedures I didn’t have the expertise or tools to undertake. Dillon came out and finished the job, doing top-notch work and taking in account the aesthetics of the unit inside and out. Very reasonable price as far as I’m concerned. My new go to neighborhood HVAC company.

David R.

Basement flooded. This is where my WFH office is, so it was a big deal. Gustafson sent out Todd to fix it. He got it fixed quickly, and charged me a very reasonable fee. Basement is warm and dry now. I can’t say enough good things about Gustafson.

Steven B.

The technician “Luis” was fantastic as usual. All the services and technicians we have used with Gustafson over 12 years have been prompt, professional, timely and reasonable over the years. I definitely approve of this vendor!!!

William R.

Our furnace went out and our regular company gave us a 2 week window for coming out. We have a RHEEM furnace and needed an authorized RHEEM dealer. I called Gustafson and they came out in 48 hrs. They were so nice and the technician –Dylan–was so helpful that I am switching companies. Really a great experience.

Sonja L.

Absolutely the best!!!! This is an honest company with very professional people working for them. The price for all work is always very fair and very reasonable!!!

Krista B.

I had the whole HVAC system installed by Gustafson about three years ago and recently requested maintenance on the system. Technician Robert Gomez was the tech that responded and he was very personable, easy to talk to, and explained what he was doing to me to service my furnace. I felt like I received thorough service and he provided advice for the future as well. Thank you, Robert!! I hope to be able to request you again in the future to do maintenance on my AC next spring.
