"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."

"Went okay. Based on some of my past tuneups, I felt like the tech could have done a little more. For example, tech had no vacuum to clean the bottom of inside the furnace. I am not sure he did any cleaning of the INSIDE of my central air unit either, but he did a great job using the hose to clean the side vents, etc., with the garden hose. Also not sure if he ever used that device with the hoses and gauge usually used to check pressure or is it Freon? For $89.95 for each (central air and furnace), I expect a super thorough job. I can’t get around these tuneups or I will void my warranty. I want to feel uber confident I am getting my moneys worth. Tech was super nice and very professional!"

"Honest, reasonable, timely & has done work for my family for 15 years. New HVAC unit recently completed. What can I say about Full Efficiency and Carlos? I have been using them for a decade and my entire family for longer. Carlos always puts the customer first, whatever it takes. As an example my HVAC unit had begun to drip & rust. Most companies would just call it normal conditions, and run. Not Carlos. He called the manufacturer and went to bat for me. A few weeks later I learned that Full Efficiency was able to convince the manufacturer to replace my unit at minimal cost. There are few if any companies that would have taken the time or even cared. Most in fact, would try to sell you a new unit. Again that's not the way Carlos works if you need a new HVAC unit he'll tell you. If all it needs is a repair, he'll tell you that too."

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