Claim This BusinessFounded in 1965, Gill's Refrigeration, Heating & Air Conditioning has spent nearly six decades earning trust in Chillicothe, Illinois, and the surrounding Peoria County region. With a flawless 5.00-star rating across six verified reviews, the family-established contractor handles everything from furnace emergencies to planned AC replacements for homeowners who expect the job done correctly the first time. Eric Tomlinson, who called at 8:30 a.m. and had a working system by noon, and Steve Girard, whose Saturday morning furnace failure was resolved before lunch, represent the standard experience locals report when reaching out.
The company name announces its scope directly: refrigeration equipment joins conventional heating and air conditioning work. This breadth sets Gill apart from contractors who limit themselves to a single equipment brand or system type. Steve Girard specifically needed heat in freezing January air after a Saturday furnace failure, and Gill arrived with the parts and expertise to restore comfort before dinnertime. That same-day responsiveness appears repeatedly across customer accounts, suggesting an operational structure built for urgency rather than delay.
Eric Tomlinson noted a very reasonable price alongside the quick turnaround, while a second reviewer named Eric described a technician who explains every step so homeowners understand what is happening inside their own systems. That combination of transparent pricing and honest communication matters when a furnace fails on a weekend. Gill's commitment to explaining the work as it progresses gives customers the confidence that they are not being sold services they do not need.
