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
