Heating & Cooling Done Right
Even, efficient comfort

A comfortable home isn't just a thermostat number — it's even temperatures, clean air, and a system you never have to think about. We size every install with a real load calculation, not a rule of thumb.
Whether you're replacing a tired furnace, adding A/C to a home with radiators, or zoning a three-story greystone, we install high-efficiency equipment cleanly and tune it to perform through a Chicago winter and a humid August alike.

Kind Words
Comfort Chicago homeowners trust
★★★★★ 5.0 from 300+ reviews
"Egan replaced our furnace and A/C and finally fixed the cold rooms upstairs with a zoning system. The house has never been this comfortable."
"We have radiators and thought A/C was impossible. They installed mini-splits that are whisper-quiet and look great. Game changer."
"Furnace died at 6am in January. Egan had us warm again before noon, same day. Professional and fair."

Heating & Cooling FAQ
Questions homeowners ask us
Furnace or heat pump — which is better for a Chicago home?
Both work here. High-efficiency gas furnaces deliver strong, low-cost heat in deep cold; cold-climate heat pumps add efficient heating and cooling in one system and pair well with a furnace as a hybrid. We'll size your home and walk through the trade-offs and rebates.
How often should I service my HVAC system?
Twice a year — heating in fall, cooling in spring. Tune-ups keep efficiency up, catch small problems early, and protect your manufacturer warranty. Ask about our maintenance plan.
Can you add A/C to a home with radiators or no ductwork?
Yes. Ductless mini-splits add efficient, quiet cooling (and heating) room-by-room without tearing into walls for ducts — ideal for vintage Chicago homes with boiler heat.
What size furnace or A/C do I need?
It's not guesswork. We run a load calculation based on your home's size, insulation, windows, and layout — an oversized system short-cycles and wastes money, an undersized one never keeps up.
