"Our furnace went out the afternoon before Thanksgiving day, we called another repair place and made an appointment for Friday, they never showed up and were not returning calls. So we started calling around and got hold of Carlson's. They came over within half an hour and diagnosed the problem. The circuit board wasn't available until Monday but they had it up and running then and were reasonably priced. We will call them next time our furnace needs any repairs."

"Seth was prompt, courteous and very knowledgeable. It was not an AC install. It was a repair. He was thorough and made certain I understood what was needed and the cost before proceeding. I will definitely be having him come out again for my furnace clean and check in the fall. I highly recommend him."

"Dave came to check my A/C. He found a fuses blown outside. This turned the a/c on for about 15 minutes. It was just too much for this 30 a/c unit. Dave gave me an estimate on a new unit and when they could install it. He is a very professional person and did his best to get my old a/c unit to run. I would recommend him and Perfect Temp Heating and Cooling. They will be back to install my new unit Friday or Saturday. It’s good to know someone who is knowledgeable about their profession. I will definitely use their service for my heating and cooling needs in the future."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

FAQs for central a/c service or repair projects in Machesney Park, IL

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.
