Chicago swings from sub-zero winters to humid, ninety-plus summers, which is exactly why the city has no shortage of HVAC companies chasing your business. Customers have left over 38,000 Google reviews across the names below, and one company alone accounts for nearly 30,000 of those, so scale is clearly not the only thing worth weighing here.
Short answer: King Heating, Cooling & Plumbing (4.7, 4,244 reviews) is our top pick for full-service HVAC, heating, cooling, and plumbing under one roof with 24/7 dispatch. Four Seasons Heating, Air Conditioning, Plumbing, Sewer & Electric has by far the largest footprint at over 30,000 reviews, and All Temp Heating and Air Conditioning (4.9, 2,483 reviews) has the tightest rating on the list. Expect $89 to a few thousand dollars depending on whether it's a tune-up or a full system swap.

Our take: We rank King first for breadth: it's one of the few companies here that reviewers trust for heating, cooling, and plumbing without switching contractors. The 4.7 is strong and consistent across a large review base, even if a couple of names on this list post a slightly higher star average on fewer reviews.

Our take: This is the company most Chicagoans have already heard of, and the review count reflects five decades in the market. Good for scale and same-day scheduling, though a few negative reviews describe slow follow-up when something needs correcting after install.

Claim this spot › How the scorecard works
Rating is each company’s live Google average. Review volume measures how many customers have actually rated them, scaled against the others on this page. Confidence combines both so a small number of five-star reviews doesn’t outrank a strong average built on thousands. Recency tracks whether people are still reviewing recently, and completeness checks basic listing info like hours and an active website. No business can pay to change any of these numbers.

What to ask before hiring an HVAC company
- Is this a repair I should make, or is the system old enough that replacement makes more financial sense?
- What’s the manufacturer and labor warranty on the equipment you’re proposing?
- Is the technician licensed, insured, and NATE-certified for this work?
- Do you charge extra for after-hours, weekend, or holiday calls?
- Can you show me the load calculation behind a new-system sizing recommendation?
- How soon can you actually get a technician out?
Frequently asked questions
Are these rankings paid?
No. Rankings come from public Google data. A business can pay to be a Featured Partner (badge and top placement), but that never changes another business’s score or position.
How did you choose these companies?
We pulled real Google Business data for HVAC companies serving Chicago and ranked them on rating, review volume, and how recently customers are still leaving reviews.
How often is this page updated?
We refreshed the data behind this page in July 2026 and revisit it as ratings and review counts change.
Should I repair or replace an old HVAC system?
Most contractors point to system age (past 12 to 15 years) and repair cost relative to replacement cost as the deciding factors. Ask for the numbers in writing before deciding.
Do any of these companies handle both heating and cooling in one visit?
Yes. King Heating, Cooling & Plumbing, Four Seasons, and Direct Improvements all cover heating, cooling, and additional trades like plumbing under one company.
The bottom line
King Heating, Cooling & Plumbing is the safe default when you want one company for heating, cooling, and plumbing with 24/7 coverage. Whoever you call, get the repair-versus-replace numbers and the warranty terms in writing before work starts.
