"I wanted to say a few things about this company. My other company sold to Dayco and this is my experience with the HVAC department. I called them because my upstairs unit was making a strange noise. Dakota came out and found the problem. He recommended what was needed and gave me an estimate. He was very professional. Later I spoke with Lane the service manager to ask a few questions. He was extremely helpful and also very professional. So, I will say that my first experience with Dayco was a very positive one. I would recommend anyone to give them a call."

"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."

"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."

"As I am writing this I realize that I am not completely satisfied with their service other than the tech was friendly and knowledgeable. Initially, I scheduled the appointment for an annual maintenance on our 3 units. On the day of the service their office called about 3 hours into the 4 hour window to inform me they needed to reschedule the appointment. The woman apologetically explained that I was the last appointment of the day, and the job ahead of me ran into a major repair that would run late into the evening. Though I had been inconvenienced by this, I understand these things happen and was still willing to give them a try. When the tech came out the following week, I walked around with him for a bit showing him where to access the units. I explained the air filters had recently been changed except for the one in the attic which he did for me using the filter I had purchased from Home Depot. When I asked him about the condensation hoses for the units in the basement he recommended I put a little bleach in the pump to keep it clean. Is not that something he should do as part of the maintenance I am paying for? I also asked him about cleaning the condenser coils on the outside units. He said he would check to see if they need it, which surprised me because that has always been standard with other companies as well. I had an appointment to go to while the tech was working. My husband was there for the rest of the service. We ended up replacing a capacitor in one of the older units, and the annual maintenance plan seemed like the most economical at $281 for 2 visits a year. But in hindsight I am wondering if it really was worth it."

"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 Roswell, 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.
