KET Home Services

KET Home Services has operated as a heating and cooling contractor in Chicago's northern suburbs for over 30 years. Based in Grayslake, Illinois, this family-owned business serves Lake Forest, Gurnee, and surrounding communities in Lake County. The company holds proper licensing and insurance, and maintains an impressive 4.9-star average across 76 customer reviews, a volume that reflects steady, reliable service rather than a surge of recent ratings. Technicians arrive in marked vehicles wearing company uniforms, and every estimator or service technician carries proper certification.

What distinguishes KET Home Services is their commitment to flat-rate pricing with no surprise line items, a structure that eliminates the anxiety of hourly meters running on difficult repairs. They offer 24-hour, 7-day emergency response including holidays, and maintain inventory for same-dayparts availability on common thermostat models and furnace components. As an Angie's List Super Service Award recipient for five consecutive years (2015-2019), they rank among the top 5% of regional HVAC contractors. Their expertise extends beyond standard furnaces to include boiler systems, whole-house air cleaners including Aprilaire 5000 units, humidifiers, and UV air purification, making them a resource for historic homes with aging infrastructure.

Homeowners who called during crisis situations praise the rapid response. When Tim Arnold needed a furnace and AC replacement, KET completed installation just three days after the quote, finishing in a single day despite adapting old ductwork to modern sizing. For John Scimeca facing a Minnesota-style winter after his 22-year-old system failed, Ken Thomas provided the most competitive estimate among four quotes with no upselling pressure. Kimberly Scott received next-morning service when her AC failed during an afternoon heat wave. These scenarios illustrate why reviewers consistently highlight the team's listening skills and respect for customer budgets.
