How Can Heat Pumps Heat and Cool?

We are going to get a little bit technical in today’s post, so strap in and learn something! We want to talk about heat pumps. Specifically, we want to talk about how it is that heat pumps are able to both heat and cool homes. Even more specifically, we want to talk about why using a heat pump year-round is such a great option in our area.

Before we do, we want to give you an important reminder. No matter what type of HVAC system you choose, and no matter who manufactured that system, there is only one way to ensure a great performance. That is by scheduling your installation with trained professionals. If you decide on a heat pump installation in Tallahassee, FL, work with our pros.

The Refrigerant Cycle …

Wait, refrigerant cycle? Isn’t that an air conditioning thing? Well—yes! But stick with us, and all shall be revealed.

As some of you may know, air conditioners don’t generate “coolness” the way a furnace generates heat. Instead, ACs remove heat from the air in homes. How do they do this? Via a heat transfer process that is reliant on the refrigerant cycle.

Basically, refrigerant is evaporated in the indoor coil. It draws heat out of the air. Then, it is sent out to the condenser coil in the outdoor unit. As it is condensed, heat is released into the air outside. This process continues until your home is sufficiently cooled.

… and Its Reversal!

So we’re still at our initial question, right? How does a heat pump cool and heat? It’s actually simple in theory. Heat pumps feature a component called a reversing valve. What’s it do?

Allows refrigerant to flow in the reverse direction!

That flips the whole heat transfer process on its head. Now, the indoor coil condenses refrigerant that was first evaporated outdoors. Basically, you’re removing heat from the air outside, and then using that thermal energy to heat your living space.

Why Do It This Way?

There are two major benefits in using a heat pump. First, there is the convenience factor. You only need one system installed. You only need one system maintained. Granted, you’ll need two tune-ups a year for your heat pump, as it’s pulling double duty. But even so, dealing with just one system, and using it throughout the year, means you’ll likely be more aware of its overall condition at any given time.

The other major benefit is energy efficiency. While the system will be comparable to more standard central ACs during the summer months, winter is its time to shine. We obviously don’t have much in the way of truly cold temperatures down here, so there is no chance of your heat pump being overwhelmed. And when you do need to take the chill out of the air, using existing heat to facilitate things is incredibly efficient.
