"We purchased a new central air conditioner and a 2-stage furnace. In addition, they needed to update the air circulation to and from the system, which was nicely done. Needed a little tweaking, and one of the owners came out to perform the simple task himself."

"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."

"I had a great experience with their HVAC services. They repaired my electrical baseboard heater quickly and made sure everything was working perfectly before leaving. The team was professional, punctual, and very knowledgeable. They also installed our new central A/C system smoothly with no issues at all. Communication was clear throughout the process, and the pricing was fair. Highly satisfied with the quality of work and customer service. I would definitely recommend them for any heating or cooling needs."

"I have been using them off and on for probably the last 8 or 9 years. They come the same day or the next day at the latest. They’re pretty good and if they are going to run late, they call and tell you immediately so you are not wondering. They are honest and the pricing is good. They won’t try to sell you any unnecessary repairs."

"I discovered that our A/C unit was not cooling properly.? On 7/5, I contacted All Temp and scheduled a service/ diagnostic appointment for 7/6.? The office staff was friendly and efficient.? Mike B. arrived within the appointment window and promptly inspected the unit.? He discovered that the contactor was bad and replaced it.? After replacing the part, Mike tested the pressure and temperature and confirmed everything was working properly.? Mike took the time to provide some helpful advice for keeping the unit operating at it's peak.? The entire appointment lasted approx. 30 minutes.? I have used All Temp in the past and would recommend them to friends and family.? In my experience, they have been honest, reliable and efficient.? I've never felt that a technician was trying to "sell me something."? A++ Rating.? *Only note is that I was expecting a call prior to technician arrival, but that's no big deal in my book!"

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