"Went well. The attic stairs we’re broken while removing / installing new furnaces. Dayco without any delay ordered new stairs to be installed. We had an issue with not using material to cover hardwood floors and did get some small scratches. We did review this complaint and they did offer to send a flooring co to repair"

"Mr Paze was the only repair service that agreed to come out on a Saturday after 7:00pm . He was very professional and personable. He took my husband down with him to look over what was wrong with our AC unit. He explained everything that needed to be done and what the cost was. After we agreed to the repairs he took care of our problem in no time. We will use his service again if need be. I recommend him highly. He is friendly, efficient and professional. He stands by his work."

"My existing HVAC system was at the end of its serviceable life, so I needed a new system. I sought quotes from 5 different companies...3 big, name-recognizable companies in the Atlanta area, as well as 2 companies from Angieslist that I had not heard of before. Thank goodness for that! When Steve came out for the quote, he pointed out all of the things that would need to be updated, and didn't try to upsell me on a Platinum or Gold-level solution that honestly made little sense in my small 60s ranch house. The install on my unit was seamless, and significantly faster than I anticipated. I'd happily recommend Premier to anyone, and am looking forward to a long, happy relationship with an HVAC service provider."

"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!"

"Steven did a great job! He visited my home promptly, identified a new coil system needed to be replaced as this was the source of the leak, found this part and installed in a timely manner. He did make a minor mistake with the installation but came back and fixed it promptly at no additional charge. Great service!"

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