What’s the Difference Between a Furnace and a Heater?

The terms “furnace” and “heater” are often used interchangeably, but there’s an important distinction. A heater is a general term for any appliance or system that generates heat for your home, which could include furnaces, boilers, or heat pumps. A furnace, on the other hand, is a specific type of heater that warms air and circulates it through ducts to heat your living spaces. All furnaces are heaters, but not all heaters are furnaces. Knowing this difference can help you better understand your system and choose the right furnace services when you need installation, repairs, or maintenance.

Can’t say enough about the great experience we had with Stay Cool! Skylar and Trey completed a system removal and new system install for us. Great workmanship and care taken. They were both respectful, kind and professional! Highly recommend Stay Cool for all your HVAC needs! They make the whole process easy. Also want to thank Travis for his diagnosis of our 18 year old system and making it operational for a few days.
