What Chicago Homeowners Say
Best HVAC investment we've made
The SL25XPV barely runs — it just maintains perfect temperature all day. Our energy bills dropped dramatically.

Heats great even in January
Skeptical a heat pump could handle Chicago winters but this thing works down to zero degrees. Impressed.

What Chicago Homeowners Should Know About Heat Pump Installation
How a Heat Pump Works
A heat pump moves heat rather than generating it. In cooling mode it works like an air conditioner, removing heat from inside your home. In heating mode it reverses the process, extracting heat from outdoor air (even at temperatures below freezing) and moving it inside. Modern cold-climate heat pumps operate efficiently down to -13°F.
Is a Heat Pump Right for Chicago?
Modern cold-climate heat pumps (like the Lennox SL25KCV or Goodman GZVE series) are designed for northern climates and maintain full heating capacity well below freezing. For Chicago's coldest days, a dual-fuel system — heat pump paired with a gas furnace backup — provides the best combination of efficiency and reliability.
Heat Pump vs. Traditional AC
A heat pump costs more upfront than a standard AC condenser but provides both heating and cooling. For homes with electric heat or high gas costs, the energy savings in heating mode can offset the price difference within 3–5 years. D's Air will help you calculate the payback period for your specific situation.
Sizing, Refrigerant, and Defrost
Heat pumps must be properly sized for both heating and cooling loads. Oversizing causes short-cycling and poor dehumidification. New systems use R-454B or R-32 refrigerant. In heating mode, the outdoor coil periodically frosts over — the defrost cycle reverses operation briefly to clear the frost. D's Air tests defrost operation on every installation.
