"The best customer service I ve experienced. Immediate telephone response (during a 3-day weekend) and Albert arrived within an hour, diagnosed the problem quickly, made the repair and thanked me for my business. Cost is fair and service is outstanding. Definitely my new HVAC guy, period. Highly recommend you call Magna Tech (Albert) for any HVAC issues."

"I was very impressed with this company.  I have worked with "others" for the last 9 years, and found Relax Air to be much more cost effective, with much more KINDNESS, care, concern and follow up.  Everything was handled expeditiously and with professionalism and they were very willing to work with me on price and budget.  All these things certainly set them apart - and they truly care about their work and the satisfaction of their customers.

In addition to the replacement of the downstairs system, I have had ongoing years and years of problems with my upstairs unit with it neither cooling or heating effectively.  It has been looked at and "worked on" many times. NO ONE in the past had identified that the duct work was failing and needed resealed in many places, nor the fact that the attic fan was not only not working but was entirely disconnected.  These things were fixed for me on a separate visit - and my upstairs is now so cold in summer that I had to add blankets!  Love it!

I am a very discerning (some might say picky) customer - and for me to tell you that I have the utmost respect for these folks and would always use them again, and again.....truly means something.  I don't throw around idle praise - but can't say enough good things here."

"I had been told by a repairman from a company I had a service contract with that my furnace badly needed a cleaning and was quoted a price of $600 for the job as well as an additional $400 to remove a nonworking humidifier. These quotes seemed exorbitant and so I got some estimates, all much lower, and chose Dominion on the basis of reviews. Terrone said my furnace did not need a cleaning, passing up an opportunity to charge me for something I thought I needed, and repaired my humidifier for less than the cost the other company had quoted for merely removing it. He showed me what he was doing, explained how my heating system worked, and charged me a fair price for the job. I would certainly call Dominion again for any HVAC needs."

"Danny treated me like an old friend with helpful and timely service. It was refreshing. He inspected the unit, found a failed capacitor caused by an add-on Michael and Sons installed last inspection. Danny replaced the failed part, removed the add-on, and I was back in business in less than 30 minutes. I have a new HVAC provider!"

"When I initially called they were nice enough to tell me if I could wait until tomorrow they wouldn't have to charge me the emergency fee & would save me some money. This trend carried through the service and I much appreciated it. When the plumber (Matt) got there he tried everything he could to clear the line. He tried to not remove the toilet (to save us some $) but the tool he had was too small. He tried the larger tool but it was too big. He informed us that he would have to come back the next day with the medium sized tool.  When he came back the next day he fixed the issue we were having and in addition, looked at some broken plumbing under the bathroom sink.  Matt was friendly, courteous and on-time. Unfortunately I wasn't home when he came either day but he was in contact with me via phone and my dad, who was at the house for us, couldn't stop talking about what a nice guy he was. Hopefully we won't need to, but we would definitely use them again!

"I have been a customer for a very long time and this scheduled maintenance and dryer vent cleaning was done by Cesar. I have to say he is one very thorough technician and I was very pleased with his inspection and vent cleaning. His service was so different than some of the ones I've had before. I even had one inspector tell me he didn't need to check in my attic which houses one of our two units. Let me tell you about Cesar, he even cleaned up behind my dryer for me. This is something that is rare in customer service. I have my HVAC seasonally maintenanced and never had a inspector be as thorough as him. The pictures he took and explained to me and the one problem he found that no other inspector had found in all this time. I tried to spare him from the attic heat for the repair and have him return on another day in the morning but he didn't mind going back in there to fix the problem for us although it was in the dead heat of the day. I just hope the company sees this review and knows what a good technician they have in Cesar."

"Michael Bowley was my technician. He was very professional, personable, knowledgeable, and responsive to my questions. The repair was quick and thorough. I’ve always been very satisfied with the service I’ve received from FH Furr technicians and will definitely call upon them again in the future."

FAQs for central a/c service or repair projects in Great Falls, VA

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.
