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.
Our qualified and experienced technicians are 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.
Mini-Split Installations & Air Handler Solutions for Elgin’s Older and Multi-Family Properties
Not every property in Elgin can run standard ductwork. Multi-family buildings, converted upper units, and homes in the city’s older, historic neighborhoods often don’t have the space or structure for a full duct system — and that’s where a properly sized mini-split or air handler makes the difference. We evaluate the building itself, not just the equipment catalog, to spec a ductless multi-zone system or a compact air handler that fits the space without compromising comfort.
See ductless mini-split installation or air handler installation for how we approach sizing and equipment selection on these jobs.
Licensed and Bonded With Elgin Itself
Licensed
City of Elgin Heating Contractor License
License 26-00034970. It’s what lets us file Elgin permits under our own number when a permit is requested and required*.
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 file the permit when a permit is requested and required*, and we register the warranty.
AC Repair and Furnace Repair in Elgin
Our shop is on Muirhead Road in Elgin, so an AC or furnace repair call here usually isn’t a long drive for us — it’s a short one. That matters most on the days it matters most: a dead AC on a 95°F afternoon or a dead furnace at 6am in January.
AC Repair in Elgin
No cooling, warm air, short-cycling, a tripped breaker, or a unit that runs constantly and never gets the house down to temperature — we diagnose the actual failure (capacitor, contactor, low refrigerant, a failing compressor) before quoting a fix, and we carry the common parts on the truck so most AC repairs finish same-visit.
Furnace Repair in Elgin
No heat, a furnace that short-cycles, a pilot or ignitor that won’t hold, or a blower that runs but never warms the house — a lot of Elgin’s housing stock is older, with furnaces retrofit into homes that predate forced air, so we check duct and airflow along with the furnace itself rather than assuming the furnace is the whole problem.
Elgin HVAC Services
Furnace and AC work permitted through the City, cold-climate heat pumps, boilers, ductless, humidifiers, dehumidifiers, air filtration and fresh-air ventilation, plus airflow and duct-leakage diagnostics when the problem isn’t the equipment at all.

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 (8 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.
Our qualified and experienced technicians are 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
CY2026 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.
Choosing an HVAC Company in Elgin
Elgin has no shortage of HVAC companies competing for the same searches. The credentials higher up this page are how you check any HVAC contractor, not just us: a City of Elgin Heating Contractor License and bond number you can look up yourself, a Google review count you can click through to real reviews rather than a curated testimonial page, and a BBB profile with its own history. An HVAC company that won’t give you a license number or point you to its own reviews is telling you something.
What a Fair, Written Quote Should Include
A quote on a new furnace, AC or heat pump should be sized to your house, not copied off the nameplate of what’s already installed, and it should show any CY2026 ComEd or Nicor Gas discount already applied rather than added on as a surprise later. On a repair, the same principle applies at a smaller scale: whatever the pricing model, get it in writing before work starts — either a flat rate you approve up front, or, if the company bills hourly, the rate per hour and an estimated number of hours, not an open-ended number that shows up on the invoice. See request a free quote on a new system, or what furnace repair typically costs in the Elgin area for repair pricing specifics.
