Claim This BusinessAbout Pro Temp of Illinois
Pro Temp of Illinois operates from Westchester and has maintained a continuous presence in the western suburban HVAC market since 1999, delivering heating and cooling solutions across the Chicagoland region including nearby communities. The company employs 20 NATE-certified technicians and maintains an A+ rating with the Better Business Bureau, supported by 336 customer reviews that aggregate to a 4.8-star average. This team handles the full scope of residential heating system work, from furnace installations to seasonal maintenance and emergency repairs, serving homeowners who demand reliable indoor comfort year-round.
As a Premier Lennox Dealer partnered with both Lennox and Carrier, Pro Temp of Illinois accesses factory-direct equipment channels and specialized technical resources that independent contractors cannot match. The company distinguishes itself through eco-friendly retrofitting programs that help homeowners upgrade to higher-efficiency heating systems while reducing environmental impact, plus custom system design capabilities for new construction projects where heating and cooling infrastructure must be engineered from the ground up. This dual focus on product access and sustainable upgrades positions the firm differently than contractors who limit themselves to cookie-cutter replacements.
Customer feedback points to specific team members who shaped positive experiences. Reviewer Shel Liang described working with Edy, who responded to questions promptly-even after hours-and kept the project moving with clear communication throughout. That same review praised the installation crew for arriving on time, maintaining a clean worksite, and resolving unexpected issues without delay. Another reviewer noted the team left a home spotless after completing a furnace and air conditioner installation, taking time to explain system operation before departing.
What Customers Say
Positive reviews emphasize professionalism and communication, with Edy named as a responsive point of contact. Both 5-star reviewers highlight tidy worksite practices and thorough system walkthroughs. The single 1-star review centers on a policy dispute regarding maintenance records rather than technical work quality.
