The Difference Between A Heat Pump And An AC Unit

Choosing HVAC equipment can be tricky. If you go with a traditional AC unit, you also have to buy a furnace. Such a purchase can take up a lot of room in your house and cost a lot of money. If you go with a heat pump, you will be able to use one piece of equipment to heat your whole house as long as you don't have to deal with extreme cold. 

Reasons to Go with an AC Unit and Furnace

A heat pump heats your house by absorbing heat from the outside air and then pumping it into your home. You might think that on a cold day there is not heat for your heat pump to absorb. As long as it is only moderately cold outside, your heat pump should work just fine. However, if it gets down to freezing or below, your heat pump will not work as efficiently as it should if it generates any heat at all. Because a furnace produces its own heat, it will work no matter how cold it gets outside. Thus, if you live in the north of the country, you need to either use a furnace or a ground-source heat pump. 

The Beauty of a Ground-Source Heat Pump

Most heat pumps will look much like an AC unit with their coils above the ground. These are called air source heat pumps, and their efficiency is subject to fluctuating air temperatures. A ground-source heat pump will have a set of coils buried in the ground outside of your home. Because ground temperatures are much more consistent than air temperatures, your heat pump will work through the winter while maintaining an impressive level of efficiency. In fact, a ground-source heat pump can be as much as 600% efficient. This means it will be vastly more efficient than a furnace, but it comes with a much higher price tag.

In the end, choosing HVAC equipment for your home depends on where you live and how much money you have available. If you live in a moderate climate, an air-source heat pump should be all that you need to keep your home warm. If you live in a cold climate, then your should go with a furnace or a combination of a furnace and an air-source heat pump. You can run the heat pump during the more temperate times of the year and use the furnace for when it gets really cold outside. If you have the money, then your best bet is to go with a ground-source heat pump. Talk to experts like C & D Cooling & Heating Co for more information.
