South Elgin, IL Heating & Cooling

HVAC Repair in South Elgin, IL

Our shop is on Muirhead Road in Elgin, and South Elgin is the closest town we serve. On a Tuesday in June that’s a footnote. At two in the morning in January, with a furnace that won’t light and a house dropping through the fifties, it’s the only thing that matters.

Distance Isn’t a Marketing Claim

It’s arithmetic, and ours is short. When your heat or air goes out, call and we’ll tell you honestly what the window looks like that night.

After-hours and emergency calls are priced higher than business-hours calls. We quote that number on the phone before a truck leaves, so you can decide whether tonight or first thing tomorrow makes more sense.

How an HVAC Repair Call Works in South Elgin

Call (847) 224-2420 or book online and tell us what the system is doing: no heat, no cooling, short cycling, a noise, water where it shouldn’t be. We repair all major brands, so it doesn’t matter who installed the equipment or whose sticker is on the cabinet.

Repair visits in South Elgin start with a flat diagnostic fee to find the problem. During office hours (9 a.m. to 5 p.m., Monday through Friday) the service call is $130; weekday evenings after 5 p.m. it is $180, and nights, weekends and holidays are $260. Each includes 30 minutes of travel and 30 minutes of diagnostics, and parts are extra. Once we know what failed, you get a flat-rate repair price and approve it before any work starts, so there is no hourly meter running while we work. After-hours and emergency service calls are priced higher than business-hours calls, and we quote that on the phone before we dispatch. If the repair turns out to be one you shouldn’t make, an older furnace with a cracked heat exchanger for instance, we’ll say so and put the replacement math in writing rather than sell you a part.

Owner Jeff Kerley is EPA 608 Universal and NATE certified, the team holds NATE Ready-to-Work, and the company holds the BBB of Chicago & Northern Illinois Complaint Free Award for 2024 and 2025.

Why Priority Scheduling Matters

It matters most in the first real cold snap of the season, which is the week everyone calls at once.

Each visit is worth up to $130 on its own, and plan members get 5% off repairs, which is how the plan works out to up to $390 in services for $240. If you’d rather book a single visit, see furnace maintenance or AC maintenance.

Rebates in South Elgin

ComEd heat pump and Nicor Gas furnace discounts are applied right on your invoice at installation. Qualifying ducted heat pumps earn $900–$2,000 off through ComEd depending on efficiency tier and heating capacity, and ductless or mixed-use systems earn $500 or $1,000. On the gas side, Nicor Gas takes $225 off a 97%+ AFUE furnace or $150 off a 95% AFUE furnace, $350 off a qualifying 95% AFUE heating boiler and $500 off a combination boiler. See ComEd Instant Discounts and Nicor Gas Instant Discounts.

There’s no application to file. We’re a ComEd Heat Pump-Trained Contractor and a Nicor Gas Contractor Circle Installing Member, so the discount comes off the invoice rather than being chased afterwards. A heat pump paired with a gas furnace backup can draw from both programs, each on its own equipment. Quotes are free and written with the discount shown, and you can prequalify for financing in about 2 minutes with no impact to your credit score.
