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.

Original equipment is 13 to 27 years old, and what went into a 1999 spec home wasn’t chosen for efficiency.

Rest Assured HVAC is registered with the Village of Huntley as an HVAC Contractor, registration #22135, so permitted replacement work goes in under our own number.

Heat Pump Discounts Through ComEd

We’re a ComEd Heat Pump-Trained Contractor. ComEd tiers the discount by heating capacity as well as efficiency, so system size matters.

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 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.
