About Four Seasons Heating, Air Conditioning, Plumbing, Sewer & Electric
Few home service companies in the Midwest have as much customer feedback on record as Four Seasons Heating, Air Conditioning, Plumbing, Sewer & Electric. Its Chicago location on West 73rd Street, near Midway Airport on the Southwest Side, shows more than 31,000 Google reviews. The company says it has been in business since 1971, and it now covers Chicago, the west, south, southwest, north and northwest suburbs, and Northwest Indiana.
Heating and cooling is still at the center of the business. Four Seasons installs and repairs furnaces, air conditioners, heat pumps, ductless mini-splits and boilers, and it also handles plumbing, sewer and drain work, water heaters and electrical jobs. The website describes the company as one of the top Lennox Premier Dealers in the country, and it advertises a free 10-year extended warranty on qualifying HVAC work, along with financing and free estimates on new systems. It also says it has twice won the Better Business Bureau's Torch Award for Ethics, in 2015 and 2025.
With that many reviews, the pattern matters more than any single story, and the pattern is consistent. Customers describe booking a next-day appointment after a combined furnace and AC failure, an estimator named Adam arriving the same day with a straightforward price, and a comfort advisor named Keith laying out several options and explaining the benefits of each. Install crews are praised for tidy work. There are some complaints too, including one about a compressor that failed soon after installation, which is not unusual for a company doing this volume but is worth knowing.
The Chicago location is listed as open 24 hours, and the website advertises 24/7 emergency service. License numbers are not listed on the pages we reviewed.
Who it suits: homeowners who want a large, established company with a long warranty on a new furnace or air conditioner, and anyone who likes having HVAC, plumbing, sewer and electrical under one roof. Who it suits less well: people who prefer a small owner-run shop where the same technician comes every time.
Before signing, ask exactly what the 10-year warranty covers and what it requires from you, such as annual maintenance, and compare the financing terms with a cash price.
