Professional AC & HVAC Installation in Elgin

From emergency AC installation during summer humidity spikes to seamless commercial and residential HVAC installations, our team ensures Elgin homeowners never have to compromise on comfort.

Owner Jeff Kerley is NATE certified in Air Conditioning Installation and Gas Heating Installation, and installs are sized to the house rather than copied from the old nameplate; a Manual J load calculation is available on request. See AC installation, furnace installation and heat pump installation for how the day goes, from sizing and AHRI matching through the City permit and commissioning.

Licensed and Bonded With Elgin Itself

Licensed

City of Elgin Heating Contractor License

License 26-00034970. It’s what lets us pull Elgin permits under our own number.

Bonded

Surety Bond on File With the City

Bond 66947798. It gives you and the City recourse if work goes wrong.

Local

Elgin Area Chamber of Commerce

A member since 2025. We live and work here.

A permitted job gets inspected, which means the gas line, venting, electrical disconnect and condensate were done to code because someone from the City is going to look at them. We pull the permit, schedule the inspection and register the warranty; you don’t chase any of it.

What a Service Call Looks Like

Call (847) 224-2420 any hour, or book online for a business-hours slot. We repair all major brands, not just the ones we install.

Repair visits in 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 honest answer is that the equipment is at the end of its life, we put the repair-versus-replace numbers in writing and let you decide.

Owner Jeff Kerley is EPA 608 Universal and NCI airflow trained, the team holds NATE Ready-to-Work, the company holds the BBB of Chicago & Northern Illinois Complaint Free Award for 2024 and 2025, and we’re a Housecall Pro Superpro for 2024 through 2026. Smell gas? Leave the house right away, call 911 from outside, and call your gas utility’s emergency line from outside before calling us.

Rebates in 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.
