"Everything went great. They showed up in the morning and had everything ready to go by about 3:00pm. We replaced an 80% efficient furnace and 10 SEER A/C with the Carrier Infinity 98% efficient and 16 SEER A/C. Because the furnace is a high efficiency condensing gas model it requires PVC intake and exhaust piping. We agreed on a suitable location out the side of the house for the new piping. The install went well. They even fixed an existing return duct in the basement that was blocked off. The basement heats/cools so much better now. In fact, we have 2-story home and the whole house is more comfortable. There's not as much stratification of the temperatures from level to level. As far as the equipment it seems to be running great. Both the furnace and A/C are 2-stage units. This means they operate at two different output levels. The thermostat is the Carrier Infinity Control with WiFi. We had a Nest with our old system, but it is not compatible with the Carrier Infinity line because of the complex controls needed to operate the system. That's okay. This new thermostat is much better anyway. It requires a proprietary communication data bus because it is constantly monitoring the state of the various components (furnace, A/C compressor, ECM fan motor, evaporator coil, etc.) and adjusting the control parameters continuously for optimal performance and efficiency. It will even put the A/C in dehumidify mode where it lowers the air flow across the evaporator coil to more effectively pull water out of the air. We are pleased enough with the system that we'd never use anything other than a high efficiency 2-stage (or even fully modulating) system when/if we ever need to replace things again in the future. This is our second positive experience with these guys. We will continue to use them for any future needs."

"The service tech was prompt, friendly, and helpful. They identified the issue with two fridges, and they recommended replacement or adjustment rather than costly unnecessary 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."

"My central air went out. John Hively responded to my request. In speaking with Mr Hively he seemed knowledgeable and sincere in his desire to help me with my issue. He arrived in a timely manner As he said he would. He evaluated the problem and explained it to me in depth in a way that I understood. He was very informative about my Carrier unit. My air conditioning unit is pretty old he related maintenance was very important and I believed him. He explained what needed to be done and that he was able to do it. And once he got started it did not take him very long. When my air went out I was bracing myself for some astronomical cost because I know nothing of these things. As a senior he explained to me that he also offered a senior's discount which I was grateful for. In the end he completed the Repair and the price was very reasonable. This young man is a hard worker. He takes pride in his work. And he has gained a customer for life. I would recommend him highly."

"We were thankful for the efficiency at which the team was at determining the issue, providing and estimate, and scheduling our service. We had two workers on the day of the replacement who were punctual, courteous, and professional. Care was taken to keep our home from being damaged and the areas were cleaned prior to departure. Thank you for getting our new furnace installed before the external temperatures went into the single digits."

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