A heat pump looks and acts just like an air conditioner in the summer time. So what’s the difference? A heat pump can also heat your home in colder weather. We’re a trusted Chattanooga heating and air conditioning company who offers maintenance, repair and replacement services for heat pump based comfort systems.
If you have an understanding of heating and air conditioning, you’ll know that it’s all about moving heat energy. In the summer, an air conditioner doesn’t create cold air and blow it into your home. Instead it removes the heat energy from the inside air, and dissipates this heat energy into the air outside. A heat pump works the same way, but in colder weather it reverses the process and pulls heat energy from the outside air, This heat energy is used to heat the air inside the home. That might not make sense at first, but remember that even cold air has heat energy.
Heat pumps are not made for heating a home when it’s 15° outside…they work better at milder winter temperatures. A heat pump is excellent paired with a furnace, especially for rural areas where a furnace is often powered by propane. In mild winter weather, the heat pump provides heat, and when the temperature drops the gas furnace takes over. This is called Hybrid Heat™ and can save quite a bit on winter time gas bills!
The cooling capability of a heat pump is measured by a SEER rating just like an air conditioner, while the heating efficiency is measured by a Heating Seasonal Performance Factor (HSPF) rating.
