37 HVAC Maintenance Contractors in Des Plaines, IL

Des Plaines sits in the Chicago metropolitan area, where January lows hover around 18 F with bitter lake-effect wind chill pushing perceived temperatures even lower. Summer highs reach the mid-80s with moderate humidity, but heating demand dominates because those sub-zero winter stretches last for months. That asymmetry makes a well-maintained furnace less of a convenience and more of a survival priority for homeowners in this suburb. Twenty-six contractors serve the area, earning an average rating of 4.7 across more than 3,600 customer reviews, and roughly half advertise around-the-clock availability. HVAC Maintenance in Des Plaines isn't a seasonal luxury when a failed heating system during a polar vortex can quickly become a safety issue.

Costs are straightforward to compare. A single AC tune-up runs $72 to $206, while a single furnace tune-up costs $82 to $227. A full HVAC inspection, covering both systems comprehensively, ranges from $155 to $412. Illinois doesn't mandate a statewide HVAC license, so credentials vary by municipality, and homeowners should verify that any contractor they hire holds the appropriate local permits for the work being performed.

Customer feedback patterns are clear. Technicians Josh Murner and Delwin Johnson receive named mentions for their work, with reviewers praising their diagnostic transparency and upfront pricing. Other homeowners note same-day or next-day appointment availability, a factor that matters deeply when a furnace fails on a frigid evening. The combination of fast response, clear communication, and reliable equipment knowledge shapes which contractors earn repeat business in this market.
