"Very professional. They did an annual service check on my furnace. While doing so, they found that my filter was wrong and could have caused major damage to the furnace. They were able to find me the correct filter in a timely manner. I'll be calling them whenever something is wrong or I need another furnace cleaning/check."

"Our tech Tristan was very helpful. He took his time to diagnose the problem and was able to repair one part but was concerned about another part. He referred Gill to us, and we were able to get a new furnace with no wait time, at really great value. The part that Tristan replaced was refunded back to our new furnace. Tristan did the install and was efficient and walk us through the new unit and made sure everything worked. Highly recommended."

"I recently had Comfair Heat and AC install a new furnace, and I couldn’t be happier with the experience. From start to finish, the team was timely, professional, and incredibly friendly. They showed up exactly when they said they would, walked me through the process, and completed the installation efficiently without cutting any corners. Their pricing was very fair compared to other quotes I received, and the quality of their work truly stands out. The new furnace runs perfectly, and the difference in comfort is noticeable already. Overall, Comfair delivered fantastic service, and I highly recommend them to anyone needing heating or AC work. I’ll definitely be using them again in the future."

"**5 Stars — Small Business to the Rescue!** Brian and Valerie of Chatfields LLC AC and Heating saved the day! Our furnace failed while guests were staying at our property. A larger HVAC company quoted $2,150 to replace the circuit board and two pressure switches. Thankfully, we sought a second opinion. Brian carefully investigated, confirmed the board and one switch were working, and replaced only the faulty pressure switch. Heat was restored the same day for $275—a $1,875 difference! Beyond the savings, Brian was thorough, honest, professional, and true to his word. Meeting his wife, Valerie, was equally wonderful. They are such a kind, warm couple who made a stressful day easier. This is why I love supporting small businesses! Chatfields stepped in where a larger company fell short and earned my trust and future business. I'll gladly continue supporting hardworking small businesses like theirs. Thank you both for your integrity and outstanding service. Highly recommended!"

"Don Berry came over this past Sept. to do maintenance for furnace and air conditioner. They were 7 years old and I'd never had maintenance (tune up) on them I also had water coming out from under the furnace so that was the catalyst for calling. Don reconfigured the pcv pipes (existing was plugged up) from the furnace to carry the water to the drain. He serviced the furnace and ran tests to get a baseline of readings. He serviced air conditioner and found it very low on refrigerant which he replaced. Also ran tests on A/C. He is very knowledgeable and friendly and did a great job. I will use them again."

FAQs for central a/c service or repair projects in Highlands Ranch, CO

Coils work to absorb heat into the refrigerant that flows through them, moving heat from one location to another. For air conditioning, the evaporator coil inside the air handler in your home absorbs heat. It then transfers the heat outside to the condenser coil, where it releases it. The opposite process happens for heat pumps. When the coils get dusty and dirty, it reduces how well these components work.

Skip regular cleanings, and dirt, debris, and mineral deposits will blanket your evaporator and condenser coils. When that happens, the coils can’t shed heat efficiently, so the system works harder and your energy bill climbs. Over time, overheating strains the compressor and can trigger a full breakdown—an avoidable repair that often costs far more than a simple annual cleaning.

AC coil cleaning is an investment that pays for itself in the benefits it provides. Dust‑caked coils force your AC to run longer, so you spend more on electricity and rack up extra wear. A quick professional cleaning restores efficiency, trims monthly bills, and eases strain on expensive parts. Over the long haul, that small yearly fee delays pricy repairs and stretches the unit’s lifespan, making coil cleaning one of the smartest HVAC tune‑ups you can schedule.

Watch for higher electric bills, rooms that stay warm no matter how low you set the thermostat, or an AC system that runs nonstop. Extra humidity and frost on the coils are also red flags. Catching these clues early lets you schedule a quick cleaning before the system overworks itself and triggers an expensive breakdown.

Your AC cleaning technician starts by shutting off the power to the unit and removing the faceplate. Compressed air and a vacuum hose blast away loose debris, followed by a coil-safe, no-rinse cleaner that dissolves stubborn grime. After the solution has soaked in, the professional wipes the fins, reassembles the housing, and restores power, leaving the system ready to cool at peak efficiency.
