"Before the service visit the dispatcher had asked for the make and model of my refrigerator so they
would be sure to have any parts needed.  The technician arrived on time and was very neat with his work.
He took everything out of my freezer, placed the items in a plastic tub I provided.  He removed the liner of the freezer compartment and then defrosted and vacuumed out the drain. He added a heater to keep it from freezing up.  It took less than an hour for the work and he put everything back in place as well as adding a screw that he noticed was missing from the freezer.  I was very pleased and impressed with the work as well as the price.  I wish I'd gotten in touch with them earlier.

"Just had my first service check up on my heating and air conditioning unit. As was the install the scheduling was easy. The technician called prior to arrival. I met him at the door and he explained everything that the service included. Then he went about his business. The report was concise and I am extremely pleased with his professionalism and manner. I highly recommend Maynor for your installation and service needs."

"They have been very good to us. We felt the price was very competitive. Everything is what we would expect from anyone. I think they do a very thorough job. They are very pleasant and easy to work with. The work takes 30-40 minutes depending on whether they have to do something. They show identification and then get to work. They clean up really well. If it's raining or anything they put those little booties on."

"Air ecperts technician Mark provided a thorough and honest assessment of 1) the condition of my hvac system and 2) determined the source of a separate issue related to a running toilet. Most importantly he confirmed a suspicion i had with another highly rated hvac/plumbing company. This other company (Streamline Services, Plumbing, HVAC & Electrical) stated a few months earlierbi had growth in my ductwork and of course suggested follow up work costing over $1,000. However, since my hvac system is about 3 years old i was of course suspicious and contacted Air Experts which I use to service other rental properties i own. They confirmed with pics that there was absolutely no growth in my ductwork or any other component of my hvac system. This alone gives me confidence to use Air Experts for my other rental properties going forward. I will no longer being using the services of the other hvac company."

"Writing I cannot recommend him highly enough! He is honest, reliable, knowledgeable, and consistently goes above and beyond. His attention to detail and commitment to finding long-term solutions truly set him apart. When our veterinary hospital experienced HVAC issues, another large HVAC company quoted us thousands of dollars in repairs that ultimately weren't necessary. He took the time to thoroughly diagnose the problem, identify the actual cause, and make the appropriate repairs. Not only has the issue not returned, but he saved our business thousands of dollars in unnecessary expenses. What I appreciate most is that he doesn't simply put a Band-Aid on a problem. He takes pride in his work, communicates clearly, and makes sure the job is done right the first time. He is always timely, friendly, and professional. It is refreshing to work with someone who genuinely has his customers' best interests in mind. I would highly recommend him"

"We were very pleased with company. In particular, their communication is ongoing and timely. The services included removal and disposal of old outdoor A/C equipment, the removal of two furnaces, one in the crawl space and one in the attic with limited access, and an electrical upgrade. The new system also had to go into the attic through a limited access area with a second in the crawl space. The county inspector was impressed with the installation of the new system in the attic."

FAQs for central a/c service or repair projects in Cary, NC

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.
