Kane County Towns We Serve

Every town below has its own page covering what applies there. Several straddle a county line; if your address is in the town, it is in our service area.

Unincorporated Kane County counts too. A house on a township road outside any village limits gets the same scheduling, the same flat-rate pricing and the same phone answered at any hour. Not sure whether your address is covered? Call (847) 224-2420 and we will tell you straight.

Licensed Where Kane County Permits Matter

Our own number

Municipal Licenses

Licensed or registered with Elgin, Aurora, Bartlett and Huntley, so permitted jobs there go in under our own name and get inspected without waiting on paperwork.

Village or county

Permits Handled

Where a permit is required, we file it with the municipality, or with the county for an unincorporated address, and handle the inspection as part of the installation.

Insured & bonded

Coverage on Every Job

General liability, commercial auto and umbrella coverage, with surety bonds on file where towns require them.

Plenty of contractors will drive to a Kane County town. Fewer are licensed by it. The difference shows up when the permit is pulled and the inspector comes out, and it is the reason we keep those licenses current. See about us for the full list of credentials.

No Heat Anywhere in Kane County?

A dead furnace on a January night is an emergency whichever end of the county the house is on, and we answer (847) 224-2420 around the clock. Check the thermostat, the breaker and the furnace door switch first; if that does not bring it back, call and we will quote the after-hours visit on the phone before we dispatch.

If you smell gas, leave the house right away, call 911 from outside, and call your gas utility’s emergency line from outside before calling us. For everything else, see emergency furnace repair and emergency AC repair.

Furnace and Boiler Heating in Kane County

Kane County winters run hard from November through March against design temperatures near 0°F, so a furnace that limps through October rarely makes it to spring. We repair every major brand. Igniters, flame sensors, pressure switches, inducer motors and control boards are the usual suspects, and most of those repairs typically land between about $150 and $900. A cracked heat exchanger usually means furnace replacement instead.

When a furnace does come out, a 95% or 97% AFUE condensing furnace qualifies for a Nicor Gas instant discount of $150 or $225 off the invoice, or $200 or $275 with a qualifying smart thermostat on the same invoice. Radiator and baseboard homes are covered too: we repair hot-water and steam boilers of any brand, and a qualifying 95% AFUE boiler gets $350 off, or $500 for a combination boiler. See boilers.

Cooling and Heat Pumps for Kane County Homes

May to September

Air Conditioning

Humid summers mean an air conditioner has to pull moisture as well as heat. We repair all brands and replace with R-32 equipment sized to the house.

Below zero

Cold-Climate Heat Pumps

Inverter heat pumps like the Amana S-Series keep heating well below zero, and a ducted system qualifies for $900–$2,000 off from ComEd.

Best of both

Dual-Fuel Systems

A heat pump paired with a gas furnace runs on electricity most of the winter and hands off to gas below the balance point.

R-410A is being phased down and its price is rising, so a large repair on an older condenser deserves a second look. See AC repair, AC replacement, heat pump installation and dual-fuel systems. For a room without ductwork, a Daikin ductless mini-split qualifies for $500 or $1,000 off from ComEd.

What a Service Call Costs in Kane County

Repairs 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, and the price is the same in every Kane County town we serve.

After-hours and emergency service calls are priced higher than business-hours calls, and we quote that on the phone before we dispatch. Replacement quotes are free, written, sized to the house rather than the old nameplate, and include the discounts. Financing prequalifies in about 2 minutes with no impact to your credit score.

Kane County HVAC FAQs

Do you serve all of Kane County?

We serve the towns listed on this page and the unincorporated addresses around them, from our shop in Elgin. If your town is not listed, call and ask; we cover more of the county than the pages above.

My town is split between Kane County and another county. Does that matter?

No. If your address is in a town we serve, it is in our service area regardless of which side of the county line it sits on. The permit, if one is required, goes to whichever municipality or county has jurisdiction over the address.

Do I need a permit to replace a furnace or air conditioner in Kane County?

Requirements vary by town. We file the permit where the municipality requires one, or with the county for an unincorporated address, and handle the inspection as part of the installation.

Do ComEd and Nicor Gas discounts apply in Kane County?

Yes. The Kane County towns we serve are in ComEd and Nicor Gas territory, so both instant discounts come off the invoice at installation.

After-hours and emergency service calls are priced higher than business-hours calls, and we quote the call on the phone before we dispatch. Repairs are flat-rate and approved by you before any work starts.
