"We were 100% satisfied with Fresh Air Heating & Cooling and would HIGHLY RECOMMEND them. Everything about the entire experience was fantastic. Short story is our heat went out on a morning when the temp was minus 6 degrees. They were able to repair the system that day and install a new one later that week. There was no high pressure sales pitch -- only excellent advice and service. We found Fresh Air Heating & Cooling on Angie's List and are now LOYAL CUSTOMERS!"

"I called Bernie this morning after my home warranty company had not assigned a tech to repair my central AC. He was not only professional but more importantly an overall great human being with the understanding we have been having excessive heat Bernie still made time to come out. Not only did he get to my house quickly he was able to replace the part needed to get me up and running. He then went above and beyond to ensure it was working correctly, changed my filter, and made sure the air was blowing at the correct temperature. He was extremely reasonable and more importantly without hassle filled out the paperwork needed so I would be reimbursed by my warranty company. If I could give him 10 stars I would and I would highly recommend using him for repairs."

"Matt did a quick check of the basement unit and then went outside. He said it likely was a failed capacitor and that's what it was when he tested it. He had a compatible part in his vehicle. Once he had installed the replacement the system ran perfectly. We were so glad we were able to be serviced the same day that I called in the problem. Hello summer."

"John contacted me immediately after I submitted my project to Angi and came out later that same day to do an AC tune-up. He was professional, easy to work with, and respectful of the property. He diagnosed a few issues and possible solutions at varying price points, and went into the pros/cons of each one. I plan on having him come back this fall to check our furnaces."

FAQs for central a/c service or repair projects in Saint-louis, MO

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.
