"Had water tank and HVAC system replaced. Karen provided full overview and options at estimate appointment. She was available by phone for all questions and concerns. Was able to get same week installation. Both Jorge’s & Jacob’s crews worked well together in same space. They were all responsible, respectful and explained post installation. Referred by my family, past customers."

"on time, and knowledgeable the technician did the job well. Also, I had a problem changing the furnace filter. The filter was getting stuck when taking it out or installing. He repaired that too."

"I had a family of racoons in my attic that took over 3 months to get rid of them. The resulting mess required all the existing insulation had to be removed (combination blown in and rolled fiberglass on top of it. Also had 2 attic fans that needed to be replaced/removed, as well as the initial hole that was torn into the roof to get in by the mama racoon. I hired Assured Insulation based on not only cost, but they are a preferred contractor of the EnergySmart Nicor rebate program. Other contractors I received a cost estimate from didn't even mention anything about rebates. This wasn't the usual mail in your form and 10-12 weeks later you receive a check. Assured did all the work and I received the max rebate right off the top of the bill. I did nothing, Assured Insulation did everything. As far as the work that was done. They did a superb job, could not have asked for a better job. Ed repaired the roof hole, removed 1 attic fan and replaced another as well as redirected the vent from my bathroom fan up thru the roof (building code) vs to the soffit. Initially he told me they may have to do that, but there were no hundreds of dollars of addons, $50 over their original bid and that included a special spray that the other contractors had said they use because of the racoons. Able and the rest of the crew, who worked together very well as a team and were very courteous and considerate of us. They performed leakage tests before starting work and after completion (as part of their requirements for the rebates, not mine). • They removed all the existing insulation, including what the racoons left behind. • Sealed all the ceiling fixtures and between walls (tagged them as well so they can be found after insulation was blown in) • Sprayed the special Microban to neutralize ceilings below from the critters presence. • Installed baffles to allow attic to breathe and allow heat to rise over the insulation. • Sealed & filled in areas that leak (Kitchen soffits open and exposed, bathroom) • Built up areas that were below the 16" height of the insulation, added additional foam backing to entrance doors to the attic(s) And lastly, if I hadn't been there during the process and came home, well you would barely know that anyone even showed up. They removed all remnants of new or old insulation, cleaned the area leading to the attics, the hallways, floors, walls. just a terrific, terrific job, well beyond my expectations. I would whole heartedly recommend Assured Insulation Solutions to anyone. I don't do testimonials like this for work, but I can't say enough about the job they did."

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