"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"

"Premier representatives were professional and courteous. My HVAC system is complicated with 4 separate zones. They provided detailed assessment of condition and problems and made recommendations at 3 price levels. Installation was done next day as promised. The crew was very careful to not track carpets, block drives, or disturb pets. The workmanship was first class with lots of attention to detail."

"I was struggling with a vendor who installed a new AC and furnace 3 years ago that required service every year. The Guardian team was able resolve the issue in 2 days at a fraction of the cost the original installer quoted. Technician Josh Bennett was able to isolate the problem in 30 minutes. He is very knowledgeable, personable, and very professional. HVAC Service Expert Dave Dover arrived the next day to complete the required repairs and washed the outdoor system. My wife and I could not be happier with Guardian service. We joined their Shield Protection Plan Membership."

"It went very well. Explanation of everything was very good. My only concern is the amount of lint left on the ground from the dryer very. If there was a way to blow that out into a bag or something would be better than all on the ground. Overall service was very good."

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