"I am very satisfied with the quality of work and professionalism of this company. I called them to make numerous repairs (listed below) that found during inspection of my new home. The repairman, Jeremy, was very respectful and efficient. Based on research, I believe the company's prices are reasonable, and I'm not looking to go bargain-basement on electrical repairs. I want quality. In about 2-3 hours, Jeremy (with the assistance of a colleague he called in once it was clear there was more work to do), made the following repairs for $1,154: 1) repaired defective GFCI; 2) repaired two sets of spliced wires and added two junction boxes; 3) repaired plastic couplings at the connections between the electric utility wire and the house main wire; 4) added connectors to all unsecured wiring in my electrical panel and labeled breakers; 5) and identified and repaired a "double-tap" wiring situation in my kitchen. Furthermore, Jeremy suggested a more cost-effective way to fix my dryer situation: recording (~$150) vs. changing the outlet (~$600). Luckily, once my dryer arrived it turned out it was three-prong and thus fit the old-style outlet so I didn't need to do either. But I still appreciated his honesty about my options. I would definitely call TE Certified Electricians again — particularly since they sent me a "5% off for life" coupon after this service."

"I gave Cool Air Mechanical a call after reading their good reviews online. Every one I dealt with on the phone was very helpful, and were able to get help out to us ASAP. Jerry C. who came out was very knowledgeable, friendly, and professional, and was able to diagnose our issue quickly and provided great options and advice. He returned with the replacement part and repaired our unit very quickly. I will definitely be calling on them, and Jerry specifically, for any work on our system in the future."

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