"Installers were prompt, professional and knowledgeable- they did a great job. I would highly recommend Shavitz for A/C repair and service. Ernie and Johnny talked me through the process, gave me an accurate time estimate and worked diligently to get our A/C back up and running on a very, very hot day."

"Went very well. Nice guys, professional and respectful. Installed top equipment. Not the cheapest price I got, but seemed the most up front and honest. Great customer service when I had a minor adjustment issue a few weeks later."

"The technician came out yesterday, June 5th and did a diagnosis on my air conditioner as there was a significant cooling disparity between the upstairs and downstairs of our two story townhome. I was expecting to possibly replace the A/C as it is getting older. However, the technician stated the AC is in good working condition and that there was a slight leakage factoring into the cooling discrepancy. That was a much less expensive repair or fix vs. replacing the whole equipment. I appreciated his honesty, time spent communicating the issue with me and professionalism. I would definitely use All Temp Heating and Air Conditioning again and recommend them to anyone dealing with air conditioning issues."

"The technician arrived within a half hour of our initial call. Although he did not have the part on hand he made a quick trip to their service center and returned immediately with what he needed. The technician was prompt, professional, and knowledgeable. I feel it's also worth mentioning that the technician is also a combat veteran who served multiple tours overseas and is in the process of becoming a licensed plumber. I think it says a lot about a company who hires veterans. I'll never call anyone but Regional Plumbing and Heating for the types of services they provide."

"I can’t recommend Rich enough. He’s always responsive and is very knowledgeable. What I appreciate most is that he’s honest and never tries to upsell services or repairs you don’t actually need. He takes the time to explain everything, does quality work, and always cleans up after himself. It’s hard to find someone this trustworthy these days, and I’ll definitely be using Rich for all my HVAC needs."

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