Reliable HVAC Service Chicago

Eco Temp HVAC provides heating and cooling service across Chicago and the surrounding suburbs from seven service hubs: Chicago, Lemont, St. Charles, Bartlett, Palatine, Downers Grove, and Kirkland. Because our technicians are dispatched from hubs throughout Chicagoland rather than a single location, we reach homes in the city, the northwest suburbs, and the western suburbs quickly — often the same day. Find your town on our service areas page or call (224) 253-8131 to confirm coverage for your address.

Yes. Eco Temp HVAC is a licensed Illinois HVAC contractor — License TGC119983 — and fully insured and bonded. Every technician who enters your home works under that license, and when an installation requires a municipal or county permit, we file the paperwork, schedule the inspection, and coordinate sign-off so the work is documented correctly for your records and your home's resale value.

Eco Temp HVAC has served Chicagoland since 2016, growing from a small family operation into one of the area's most trusted HVAC companies with a 4.9-star average across our Google review profiles. We're still local and family-owned — the same standards that built our reputation apply on every furnace repair, AC installation, and maintenance visit we make today.

Always. Our on-site call center is staffed with live people 24 hours a day, 7 days a week — no phone trees, no overnight answering service. Before your appointment you'll receive an alert with a photo of your technician so you know exactly who to expect at your door, and after the work is complete we follow up to confirm everything was done to your satisfaction.

Our technicians are NATE-certified, and Eco Temp HVAC holds three manufacturer certifications that require ongoing training and verified customer satisfaction standards: top-rated American Standard Customer Care Dealer, Navien Service Specialist, and Certified Mitsubishi Diamond Elite Contractor. These aren't badges — they determine how equipment is installed, how warranties are honored, and in Mitsubishi's case, how much warranty coverage we can pass on to you.

Three layers. First, every job is backed by our 100% customer satisfaction guarantee — if something isn't right after we leave, we come back and make it right. Second, new system installations include a 1–2 year labor warranty depending on the system. Third, most new installations carry a 10-year manufacturer warranty — and because we're a Certified Mitsubishi Diamond Elite Contractor, qualifying new Mitsubishi systems, including ductless mini splits, receive an additional 2 years of manufacturer coverage for 12 years total. That extended coverage is exclusive to Diamond Elite contractors.

No. Eco Temp HVAC provides 24/7 emergency HVAC service with no premium charges for nights, weekends, or holidays. A furnace that dies at 2 AM in January costs the same to diagnose as one that fails at 2 PM on a Tuesday — and our service vehicles are stocked with common parts for major brands, so most repairs are completed in a single visit.

The Eco Home Program is our HVAC maintenance membership for Chicago-area homes and condos, starting at $19.95 per month when paid yearly. Members get 10% off qualifying repairs, services, and air purification products, a $100 per year credit toward a future new HVAC system, $50 off the standard diagnostic fee, priority scheduling, and scheduled springtime AC and autumn heating cleanings that help satisfy manufacturer warranty requirements. See full details on the Eco Home Program page.

Yes. In addition to complete residential heating and cooling service, Eco Temp HVAC provides commercial HVAC installation, repair, and preventative maintenance for Chicago businesses — from rooftop units to large-scale systems and multi-unit residential properties.
