"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."

"R&J Preventative Maintenance responded immediately (on a Sunday!) and they had someone out the next morning to diagnose and repair the issue with our 2005 beverage fridge! We did not want to replace it and he had the parts with him and was able to repair! Amazing! (He also serviced our Sub-zero fridge!) We will definitely use them in the future and highly recommend!"

"Installation was GREAT!!!! Slyvester answered all my questions and was very professional and friendly. A/C working great. There was a mix up with payment up front, which costed about 35 minutes, but it was resolved and customer service said they would resolve this for future customers. If you plan to use multiple payment methods, my recommendation would be to have a backup plan or call the front office to arrange things before installation."

"Phoenix HVAC has been great! I needed maintenance on my A/C having never done any on it for 13 years. Bob was great at explaining all that he was doing and he comped me on a part of the service because they had to reschedule me 2 times due to their schedules getting so busy with the latest extreme heat. Speaking of rescheduling, it's not common practice for them and Maggie, their office manager (and Bob) were extremely apologetic about it. I understood the circumstances. I was not in peril with no A/C and others were, so I was ok to wait a few days from original date. Customer Service was excellent, no pushy sales pitch and quality work! I've already recommended them to my neighbors!"

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