Four Seasons Heating, Air Conditioning, Plumbing, Sewer & Electric

Four Seasons Heating, Air Conditioning, Plumbing, & Electric has served Chicago homeowners since 1971, building a track record across more than five decades of extreme Midwestern winters and sweltering summers. The company holds licenses across heating, cooling, plumbing, and electrical trades, maintaining a 4.7-star average across 28,247 verified reviews, the largest review volume of any HVAC contractor in the metropolitan area. With ten locations spanning Chicago, the west, north, and southwest suburbs, plus Northwest Indiana, the company dispatches technicians around the clock, every day of the year.

As a Lennox Premier Dealer, Four Seasons installs and services factory-certified systems backed by manufacturer Training Excellence awards. The company is one of only two HVAC contractors in Illinois to earn the Better Business Bureau Torch Award for Ethics twice, claiming the honors in 2015 and again in 2025. Unlike most area contractors, the company guarantees tune-ups with a one-year No-Breakdown Promise on air conditioning, meaning a technician returns at no charge if your system fails during the coverage period.

Reviewers name Keith Williams for taking 45 minutes to explain heating load calculations and proper furnace sizing for a townhouse with limited baseboard, a level of engineering detail that rival companies skipped. Technician Adan Ruiz and Edgar installed a replacement system over multiple visits, with a supervisor inspecting work mid-installation and customer support scheduling a post-completion quality audit. Homeowners citing same-day arrival during holiday weekends credit the company's around-the-clock staffing for preventing frozen pipes and water damage.
