Furnace & AC Replacement in Hoffman Estates, IL

Most of Hoffman Estates went up in waves of subdivision building, which means whole streets tend to reach the end of their equipment life at roughly the same time. If your neighbors are all replacing furnaces, there is a reason.

What We Do in Hoffman Estates

Both utilities

Full Rebate Stack

Hoffman Estates is ComEd and Nicor Gas territory, so both instant discount programs are open to you. On a heat pump with gas backup, each utility’s discount applies to its own equipment.

Right-sized

Furnace & AC Replacement

Subdivision-era equipment was rarely sized by calculation. We run the load before we quote, which is often why our tonnage differs from what came out.

Measured

Duct Diagnostics

Original ductwork in a 1970s split-level is frequently the reason the upstairs never keeps up. We test it rather than assume.

How a Replacement Goes in Hoffman Estates

Replacing a furnace or air conditioner is a one-day job when it is planned properly. The planning is the part most quotes skip.

The estimate visit is where the work happens: we measure the house and size the equipment to it, look at the ductwork and the venting, check the electrical for a new condenser or heat pump, and write a quote that lists the equipment by model with any ComEd or Nicor Gas discount already subtracted. On installation day the old furnace or condenser comes out and is hauled away, the new equipment goes in with AHRI-matched indoor and outdoor components, and we commission it by measuring airflow, temperature rise and refrigerant charge. Where the Village requires a mechanical permit, we file it and the work gets inspected. The details are on our furnace replacement, AC replacement, furnace installation and AC installation pages.

If both the furnace and the air conditioner are near the end, this is also the moment to price a cold-climate heat pump against a new AC, because the ComEd discount only exists on the heat pump side. With a gas furnace as backup that is a dual-fuel system and both utilities’ discounts apply, each to its own equipment. An older system that just needs a part is a different conversation; see furnace repair and AC repair.

How Repairs and Replacements Are Priced in Hoffman Estates

Every repair call starts 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 in writing, and nothing happens until you approve it. There is no hourly meter running while we look for parts, and the price you approve is the price on the invoice.

After-hours and emergency calls are priced higher than business-hours calls. We tell you the difference on the phone before anyone is dispatched, so you can decide whether tonight or tomorrow morning makes more sense. Either way, (847) 224-2420 is answered 24/7, and we repair all major brands of furnace, air conditioner, heat pump and boiler, not just the ones we install.

Replacement quotes are free, written and include any utility discount you qualify for. We size the equipment to the house as it is today rather than the old label (a Manual J load calculation is available when it’s needed, requested or required), match the indoor and outdoor units by AHRI listing, and haul the old equipment away. Where the Village of Hoffman Estates requires a mechanical permit for the replacement, we file it and the work gets inspected, which is the point of the permit. If the timing is wrong for a big purchase, you can prequalify for financing in about 2 minutes with no impact to your credit score.

Both Rebate Programs Apply Here

Hoffman Estates homes on ComEd can take heat pump instant discounts applied at installation with no application to file. ComEd heat pump instant discounts run $900 to $2,000 on a qualifying ducted heat pump depending on efficiency tier and heating capacity, up to $2,000 at 2.5 heating tons or more, and $500 or $1,000 on a qualifying ductless system. A qualifying ENERGY STAR smart thermostat we install adds $75. Nothing to apply for; it is taken off the invoice. See ComEd Instant Discounts.

Homes on Nicor Gas take the furnace and boiler discounts on the same invoice. For homes on Nicor Gas, the furnace discount is $225 on a 97%+ AFUE furnace or $150 at 95%, rising to $275 or $200 with a qualifying smart thermostat on the same invoice. Heating boilers at 95% AFUE earn $350 and combination boilers $500. Every one of them comes off the invoice at installation, with no application to file. See Nicor Gas Instant Discounts.

Hoffman Estates HVAC FAQs

How old does a furnace have to be before replacing makes sense?

Most residential furnaces run 15 to 20 years and air conditioners 12 to 17. Check the date on the data plate inside the burner door.

Can I use ComEd and Nicor discounts on the same job?

Often, yes. They cover different equipment: ComEd for heat pumps, Nicor for gas furnaces and boilers.

Who handles the permit on a replacement?

Ask us when you call and we’ll tell you how permitting works for your address. Permitted replacement work gets inspected, which is the point of the permit.

Why did you quote a different size than my old system?

Because we sized it to the house rather than copying the old nameplate. Equipment installed decades ago was often oversized by rule of thumb, and a Manual J load calculation is available on request to verify the sizing (it may carry an additional cost).

Do after-hours calls in Hoffman Estates cost more?

Yes. After-hours and emergency service calls are priced higher than business-hours calls, and we quote the difference on the phone before anyone is dispatched. The diagnostic fee is flat, and the repair itself is a flat-rate price you approve before work starts.

Do you service all brands, and how do I book?

We repair every major brand of furnace, air conditioner, heat pump and boiler, and install Amana, Daikin and AprilAire equipment. Call (847) 224-2420 any hour, or book online for a business-hours visit.
