Huntley & Sun City HVAC
HVAC Repair and Replacement in Huntley, IL
Sun City Huntley is 5,489 homes. Del Webb broke ground in 1999 and finished in 2013, which means the original furnaces and air conditioners in the earliest sections are now pushing 27 years old, and even the newest are past 13.

Gas Furnace and Boiler Discounts Through Nicor Gas
On a 1999-vintage system, the rebate numbers change the math completely. We’re a Nicor Gas Contractor Circle Installing Member, so these come off the invoice at installation.
| Equipment | 2026 discount |
|---|---|
| Gas furnace, 97%+ AFUE | $225 |
| Gas furnace, 95%+ AFUE | $150 |
| Furnace 97%+ AFUE + ENERGY STAR smart thermostat | $275 |
| Furnace 95%+ AFUE + ENERGY STAR smart thermostat | $200 |
| Heating boiler, 95%+ AFUE | $350 |
| Combination boiler (heat + domestic hot water), 95%+ AFUE | $500 |
| Smart thermostat alone (one per household) | $25 |
Heat Pump Discounts Through ComEd
We’re a ComEd Heat Pump-Trained Contractor. CY2026 ComEd tiers the discount by heating capacity as well as efficiency, so system size matters.
| Ducted or centrally ducted mini-split | Discount |
|---|---|
| 15.2+ SEER2 / 9.4 EER2 / 8.1 HSPF2, under 2.5 tons | up to $900 |

| 17+ SEER2 / 9.4 EER2 / 8.5 HSPF2, under 2.5 tons | up to $1,500 |
| 17+ SEER2 / 9.4 EER2 / 8.5 HSPF2, 2.5 tons and up | up to $2,000 |
| Ductless or mixed-use mini-split | Discount |

| 17+ SEER2 / 9.4 EER2 / 9 HSPF2, 1.5 tons and up | up to $1,000 |
Add an ENERGY STAR smart thermostat with the install and it’s $75 more on any tier, up to $2,075 on a Tier 2 ducted system. See CY2026 ComEd Instant Discounts for the full program.
What Actually Qualifies for ComEd
ComEd is stricter than most people expect, and a few conditions trip up jobs that otherwise look fine.
Trained contractor
The Installer
It must be installed by a ComEd Heat Pump-Trained Contractor. We are one. Self-installation doesn’t qualify, and neither does a contractor who isn’t in the program.
AHRI listed
The Listing
The equipment must be in the AHRI Certification Directory, rated under AHRI Standard 210/240-2024. Manufacturer marketing numbers aren’t enough.
700 GWP or less
The Refrigerant
Refrigerant must be at or below 700 GWP. R-32, which Amana and Daikin now use, is roughly 675 and qualifies. Under the EPA’s sell-through rule (40 CFR Part 84), remaining R-410A equipment became eligible on July 27, 2026. We confirm the refrigerant on your model before we quote it.
$75 bundle
The Thermostat
The $75 only applies if the thermostat is purchased from and installed by the heat pump contractor. Buy it yourself and submit online or by mail and it won’t qualify for the bundle.
There’s No Application to File
The discount comes straight off the invoice. We’re enrolled in both programs, which is what lets the discount be applied against the job rather than chased afterwards with a mail-in form.
Quotes are free and written with the discount already shown, and you can prequalify for financing in about 2 minutes with no impact to your credit score.

Huntley HVAC FAQs
Is my Sun City furnace old enough to replace?
If it’s original to the house, almost certainly. Check the date on the data plate inside the burner door.
Do the CY2026 ComEd and Nicor Gas discounts stack?
They apply to different equipment: Nicor Gas to gas furnaces and boilers, ComEd to heat pumps. A heat pump with a gas furnace as backup can draw from both.
Are these amounts current?
Both are the 2026 programs, for qualifying equipment installed by December 31, 2026. Funding is limited and either utility can change or end its program early.
How do I know which tonnage tier I’m in?
Heating capacity in Btu/h divided by 12,000. Heating capacity only, not cooling. We’ll confirm it when we size the system.
Do I have to file anything?
No. Both utilities’ instant discounts come off the invoice at installation.
Do you pull Huntley permits?
Yes, under Village of Huntley registration #22135.
