"Called another company I was familiar with but had to pursue them for 5 days! No heat and told it was best to replace the entire unit by 3rd day and they'd order the parts (3 men, 4 hours, & $3k was what I was told). Finally, decided it was too much suffering and temps were dropping. Called Relax Air and he came within the hour, did a thorough analysis. Very professional. The final outcome was one of 3 parts were broken. Also a parts dealer, returned with the parts and tried each one. It was the module, fixed in one day, and for under $1k. He also checked/fixed the humidifier (which said initial company said they did upon initial repair visit and 2 yrs ago for regular maintenance) and adjusted the heating so the house is now perfectly balanced. After 4 years living here, finally no more cold spots!"

"ARS installed my A/C and furnace system about five years ago and they have been doing the maintenance and any repairs since then. The technicians are knowledgeable and professional. They do not try to sell unnecessary repairs or equipment."

"Very well. Technician, John, was patient and thorough as he cleaned and took readings of the systems. He took the time to walk me through the maintenance and care that I need to take care of the Heating and water heater systems of my newly acquired condo in Fairfax County Virginia."

"Scott was just as nice as could be and did an awesome job in repairing my air conditioner/HVAC unit on time and efficient and very quickly had me up and cooling down in less than half the time I expected. My thanks for everything and I'll be passing around the Fauquier Mechanical name to anyone else who is a senior citizen in the future. Great job and thanks again !!! G.H., Bealeton, VA"

"Technicians were on time and very courteous.  They thoroughly inspected and cleaned my 15 yr old air conditioner and changed my air filter as advertised.  Although they indicated that the system was nearing the end of its life due to high readings for volts, and strain on the motor, etc., they did not pressure me to unnecessarily replace parts at this time.  They did provide me with a few options for repairing or replacing the system in the future should it fail, all without the high pressure attempt to sell me more than I need at the moment (something I hate). I would definitely recommend both the company and technicians to others."

"It went very well. They did a good job. The cost was over $400. I don't know whether or not that's too high or not. I seldom have plumbers in so I can't say the cost was high, although I was surprised it was $400, but that could be the going rate. He seemed very agreeable and very happy. I needed something and he was happy to get it. He was very knowledgeable and helpful in that regard. As for the quality of their service, so far so good. Everything went okay. It stopped leaking."

FAQs for central a/c service or repair projects in Warrenton, 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.
