You’ve probably come across rebates and state programs for discounts on air-to-air heat pumps? But what exactly is an air-to-air heat pump? It’s relatively simple, and the way an air to air heat pump works is by extracting heat from the outside air and transferring the heat to the inside air. They are actually the most common type of heat pump, and typically the cheapest.
While an air conditioner extracts cold air and transfers it inside, a heat pump functions similarly but in reverse.
An air source heat pump is relatively easy to install, and inexpensive, making them one of the most commonly used types of heat pump. While historically they have had some limitations because of reduced efficiency once the temperature drops below 5 Fahrenheit, which meant that often you would need a secondary heat source for colder days, the technology has significantly improved over the last few years.
Some of the better quality heat pumps can now provide efficient heating at temperatures as low as -22 Fahrenheit, meaning the system can be used all year long, without interruption. It is often these cold climate heat pumps that are eligible for rebates and tax credits.
If you are in an area that uses natural gas or oil for heating, switching to a air source heat pump can significantly reduce your overall energy costs and consumption, even when calculating initial costs for purchase and installation. The savings aren’t as drastic when compared to electric heat, however; you are still looking at a 30% savings on your energy bill.
