0 stars if I could. Bought a faulty (not to mention overpriced) surface igniter, called back five minutes later after installing, of course they didn’t stand behind their part. Go to Grainger instead. Same (working) part, half the price.

What Is a Heat Pump—and How Does It Work?
A heat pump is an energy-efficient HVAC system that transfers heat rather than generating it. In the summer, it works like an air conditioner by pulling warm air out of your home. In the winter, it reverses direction, drawing heat from the outside air, even in cold temperatures, and bringing it inside.
Key Benefits for St. Charles Homeowners:
Energy efficiency: Uses less electricity than traditional HVAC systems
All-in-one solution: Heats and cools with one unit
Lower operating costs: Especially when paired with a high-efficiency thermostat
Long-term value: Fewer components than systems with a separate furnace and AC
