"It used a coupon for that too. Definitely would use them again. Excellent work. It probably took about an hour. He did some things he had not done before. He looked at my humidifier and then there's a little drain, a little connection, it had something to do with the cleaning, a little box, or something, I can't think of the name of it. Anyways, he told me how to clean it, he took it out and told me how to keep it clean. He changed the filter on my humidifier. I was real pleased with that little humidifier box because I didn't know anything about it. He told me how to put bleach and whatever down it to keep it from mildew. He was very thorough, real thorough. That's the first time I used All Temps. It was a very good impression. I may use them again, I'll just wait for another coupon though because the regular price for the inspection is very high. It's real high; they charge you trip charge, and labor charge and price charge. I'll just wait for a coupon again."

"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."

"Outstanding customer service provided by Sean when I needed a really bad drain backup cleared. He quickly came out to my home IN THE EVENING and took care of clearing my drain as well as the mess that was there from the stinky and gross overflow. When he finished the job he gave me some great tips on how to avoid this from happening again. So happy with his service and the bonus recommendations to keep my drain clean and clear. Highly recommend Legendary... and Sean! He has helped me with my furnace and my AC previously and is a great tech that knows his stuff! He's quick, polite and cleans up everything when done. BEST HVAC TECH & PLUMBER!!"

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