"Reliable, honest service, and fair prices. They just did a two-system replacement for us and it went extremely well. I've been working with Robby and his team for over 10 years on behalf of third-party clients and he is one of the most trustworthy contractors I've known. When I moved to the Atlanta area two years ago it was a no-brainer to hire R Wiley for my home's yearly HVAC maintenance package and I'm glad I did. We've had Miguel, one of R Wiley's outstanding technicians out for service and maintenance and I've been happy with his work and helping to diagnose issues. When it came time to replace our very old AC & Furnace units, there was no sales pressure - just consultative solutions. R Wiley's pricing was in line with some of the more affordable bids and they don't try to push you into super high-priced marked-up units or things that should be included with installation, or all those "financing" programs where you end up paying way more for your project. Installation with Marvin was awesome - they were done with two units in one day and what a difference it's made. Overall an awesome experience from day one, with a successful multiple unit replacement. I'm glad I have them to continue to keep the units serviced on an annual basis as well. Highly recommend!"

"The technician was prompt, professional, and provided several options for solving my issue. Given that the current Trane system was 25 years old, he also provided written estimates for two different replacement systems. I opted for the parts replacement and repair and am pleased with the result. The company has also called since to check to see if I was satisfied with their service. Way to go TE Certified!"

"Hired these guys to replace my original heating and A/C unit. They seem to have done a good job--it works fine. Furnace unit has filter and housing is a little wonky, but it seems to work. They also installed a fancy thermostat which can be read and operated by my phone over the internet. I wasn't too impressed with the thing at first, but I'm away for periods and I've been very pleased with it."

"I want to give a review of the Exceptional service that I received today from Cool Air Mechanical service technician Enri Jasmin. If I could give higher than a 10 star I would. When Enri first arrived he assessed the unit to see where Freon was leaking from. He went into the attic & did a leak test, which wasn't finding where the leak was coming from. He made great efforts to locate the problem both inside & outside. I had 2 other technicans look into the problem prior & wasn't able to find the problem. Enri was so professional & thorough in his analysis. I couldn't be more satisfied with his service. My AC unit upstairs is working perfectly. Just truly EXCEPTIONAL SERVICE!!!! Ms. Bowden"

FAQs for central a/c service or repair projects in Lawrenceville, GA

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.
