Chicago’s housing stock (ranging from two-flats and bungalows to high-rise condos) spans a wide range of HVAC configurations. Most Chicago homes have natural gas forced-air furnaces, making them straightforward candidates for ecobee, Nest, or Honeywell installation.

Do You Need a Professional in Chicago?

DIY is reasonable if:

Call a pro if:
– No C-wire and you want to avoid the ecobee PEK setup
– Radiant or steam heat (2-pipe or 1-pipe systems common in Chicago’s older housing)

– High-rise condo with building-controlled HVAC (check with your building management)

Stack ComEd and Nicor Gas Rebates

Chicago homeowners typically have two utility accounts, and both have run smart thermostat rebate programs independently:

ComEd (electric): Offers rebates for ENERGY STAR smart thermostats through its energy efficiency programs. Verify current amounts at comed.com.

Nicor Gas: Offers rebates for qualifying ENERGY STAR appliances including smart thermostats. Verify at nicorgas.com.

Can you claim both? Potentially. They’re separate utilities with separate programs. Confirm with each whether the same thermostat qualifies for rebates from both accounts.

Chicago’s HVAC Quirks

Radiant and steam heat: Chicago’s older housing stock (1900s–1940s two-flats and greystone buildings) often has radiator-based heating, either steam (1-pipe or 2-pipe) or hot water. Standard smart thermostats work with 2-wire steam systems in basic configurations. Verify compatibility before purchasing.

Zoned systems: Some larger Chicago homes have multi-zone forced air, multiple thermostats controlling separate areas. Smart thermostat installation in zoned systems may require HVAC technician involvement to ensure zone controllers are compatible.
