62 Emergency HVAC Contractors in Chicago, IL

Emergency HVAC in Chicago is a year-round need. January lows near 18°F make a failed furnace an urgent safety issue, while July heat waves push air conditioning failures into the same category. Chicago's 45 emergency contractors account for 100% 24/7 coverage across the sampled market, with a 4.8-star average from more than 44,000 reviews — a sign that emergency response quality holds up under real demand.

After-hours weekday calls run $165–$330. Weekend service calls range from $193–$358. Holiday and major holiday calls carry the highest premium at $248 and up. These are baseline premiums — parts costs add to the total depending on what failed. Illinois local licensing applies rather than a statewide HVAC credential, so emergency contractors operating across different Chicago suburbs may carry varying municipal certifications.

Four Seasons is the most frequently reviewed emergency provider in Chicago, with reviewers noting fast scheduling and professional technician conduct as consistent strengths. All Temp Heating and Air Conditioning earns specific praise for same-day availability — five of eight sampled reviewers name rapid dispatch as the reason for a positive emergency experience. Deljo Heating, Cooling & Plumbing draws repeat customers who cite fair pricing on emergency calls, with at least three reviewers calling out honest assessments before any work begins — an important factor when after-hours urgency creates pressure to approve repairs quickly.
