"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!"

"Their service has been competent and professional. Since installation, I've used them twice annually to do routine maintenance checkups, and they're competitive, call before they come, and arrive within the stated window. Over some 20 years, I've had a good experience with the company staff and its technicians and their work. I would consider them for bids on replacement systems as needed. Description of work: Annual maintenance service on both A/C and furnace. Previous systems replacement. Thermostat replacement."

"Its 90+ degrees in GA and my AC unit goes caput. I reach out to Le's. Charlie calls me back in less than 2 minutes. A hour later at 7pm his crew is at my house. He requested I watch as he tests the unit. He showed me the problem, quoted me the options to repair or replace. He drew up the service agreement and a day later I had my new unit. The crew was very respectful, hard working, and went the extra mile to make sure my floors were covered and everything was cleaned up. Nobody looks forward to replacing an HVAC unit but Charlie and Crew made it a very pleasant experience. I will definitely call them again any time I have a problem with my HVAC."

"OUTSTANDING!! Jonathan showed on time, very polite and went right to work. Eventually his tools were not quite up to the job (the clog was deeper than his snake could reach) so he fixed the other problem (replaced the shutoff valve under a toilet) while waiting for word from the office. Eventually he came back the next day with a longer snake and cleared the drain! Charged me the quoted price, never tried to upsell or overcharge me even though it took much longer than they expected. Totally proffessional and absolutely committed to providing the service you want. I would absolutely hire these guys again!"

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