Professional AC Service in Highlands Ranch

When summer temperatures climb across Highlands Ranch, your air conditioning system becomes essential for maintaining comfort in your home or business. At Gustafson Heating & Air Conditioning, we understand that reliable cooling isn’t just about comfort—it’s about protecting your investment and ensuring your system operates at peak efficiency throughout the demanding summer months. Our comprehensive AC service programs address every aspect of your cooling system’s performance, from routine maintenance checks to complex diagnostic procedures that identify potential issues before they become costly repairs.

Regular air conditioner service extends far beyond simple filter changes. Our certified technicians perform thorough multi-point inspections that examine refrigerant levels, electrical connections, condensate drainage systems, evaporator and condenser coils, blower motor operation, and thermostat calibration. Each component plays a critical role in your system’s overall performance, and even minor issues can significantly impact energy efficiency and cooling capacity. By identifying wear patterns and addressing maintenance needs proactively, we help homeowners avoid the inconvenience of unexpected breakdowns during the hottest days of summer.

Comprehensive Central Air Maintenance Programs

Central air systems require specialized attention due to their complex network of components working together to cool your entire home. Our maintenance programs focus on optimizing airflow throughout your ductwork, ensuring proper refrigerant charge, and verifying that all mechanical components operate within manufacturer specifications. During each service visit, we measure temperature differentials across your evaporator coil, check superheat and subcooling levels, and test capacitor microfarad ratings to ensure your system delivers consistent, efficient cooling performance.

The importance of professional AC service becomes evident when considering that cooling systems can lose up to 5% efficiency each year without proper maintenance. This translates directly to higher utility bills and reduced comfort levels. Our technicians use advanced diagnostic equipment including digital manifold gauges, thermal imaging cameras, and precision electrical meters to evaluate system performance comprehensively. These tools allow us to detect issues invisible to the naked eye, such as minor refrigerant leaks, deteriorating electrical connections, or developing mechanical wear that could lead to premature component failure.

Common Air Conditioning Issues We Address

Throughout our experience serving customers in Highlands Ranch, Englewood, and surrounding areas for more than 45 years, we’ve encountered virtually every type of AC problem imaginable. Some issues develop gradually, while others appear suddenly without warning. Our service approach addresses both immediate concerns and underlying conditions that could affect long-term reliability.

  • Refrigerant leaks and charge issues: We use electronic leak detectors and UV dye testing to pinpoint even the smallest leaks
  • Frozen evaporator coils: Often caused by restricted airflow or low refrigerant, requiring systematic troubleshooting
  • Compressor failures: We perform comprehensive electrical testing and mechanical assessments to determine repair versus replacement options
  • Capacitor and contactor problems: These electrical components frequently fail due to voltage fluctuations and heat exposure
  • Drainage clogs: Condensate line blockages can cause water damage and system shutdowns if not addressed promptly

Central Air Conditioner Service

Modern air conditioning systems offer remarkable efficiency improvements compared to units manufactured even a decade ago. However, achieving optimal performance requires proper installation, regular maintenance, and occasional adjustments based on changing household needs. Our service technicians evaluate factors including home insulation levels, window placement, occupancy patterns, and heat-generating appliances to recommend customized settings that balance comfort with energy conservation.

Since 1971, Gustafson Heating & Air Conditioning has delivered quality customer service, reliability, and expertise in heating, cooling, and ventilation to our residential and commercial clients. As a Rheem Team Top 10 Contractor in the United States, our highly-trained technicians, and responsive support staff, offer customized solutions to fit your budget. We understand that every home has unique cooling requirements, and we tailor our service recommendations accordingly. Whether you need to optimize an existing system or evaluate replacement options, we provide honest assessments based on actual performance data rather than sales quotas.

The investment in professional AC service pays dividends through reduced operating costs, fewer emergency repairs, and extended equipment lifespan.

Gary W.

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.
