Heat Pumps

When it comes to keeping your home comfortable year-round in Northwest Indiana, it's essential to have an efficient and reliable heating, ventilation, and air conditioning (HVAC) system. One increasingly popular option for homeowners in the region is the heat pump. In this article, we will explore what a heat pump is and why it's a viable choice for your HVAC needs

The Benefits of Heat Pumps for Homeowners in Northwest Indiana

What Is a Heat Pump?

A heat pump is an HVAC system that provides both heating and cooling for your home. Unlike traditional furnaces or air conditioners, heat pumps work by transferring heat rather than generating it. They utilize a refrigeration cycle to move heat from one area to another. During the colder months, a heat pump extracts heat from the outdoor air and delivers it inside to warm your home. In the summer, it reverses the process, removing heat from your home's interior and releasing it outside to cool your indoor space.

Cost of Operating a Heat Pump vs Furnace or AC Unit

Cost of operating is a big advantage to heat pumps. Heat pumps can be a higher cost investment initially to install, but with federal and local government incentives and rebates, heat pumps are becoming a more affordable option for heating and cooling needs, even in Northwest Indiana.

With a traditional furnace, for instance, your efficiency is typically in the 94 - 97 percent efficient range. That means for every dollar spent 94 - 97 cents is converted to energy to heat your home and the other remaining percentage is escaping through your chimney. So if you have a furnace that has a rating of 95 efficiency, 95 cents is in heat and 5 cents goes out the chimney.

You can never get more for your dollar on a furnace because you're always losing some out of the chimney. Whereas in a heat pump for every dollar you spend, you get more than that back in heat.

With a heat pump you are getting a much higher efficiency, sometimes as high as a 2-1 ratio. So for every dollar you spend on energy cost, you are getting up to $2 in heat for the actual cost of only $1, so it's a much more efficient way to heat and cool your home.

Because heat pumps run off of electricity alone and not gas like a furnace they can even be run by solar panels. With the rising interest in solar power or even individuals wanting to not be so reliant on the government for their heating and cooling supply, heat pumps partnered with solar panels is a really great alternative to the traditional form of heating and cooling your home.

Heat pumps typically have a higher SEER rating than traditional air conditioners too, which makes them a great option for cooling needs too. A great way to understand SEER rating is to think of it like miles per gallon for your vehicle. The higher the SEER rating, the more efficient it is just like the getting better MPG on a new car. The more efficient a unit is, the more cost efficient it is as well.

Backup/Emergency Heat needs when implementing Heat Pumps in Northwest Indiana

We've always said, up until the last couple of years, that heat pumps make sense if you're located near or south of Indianapolis. Because the temperature doesn't get as cold as it does here, in Northwest Indiana, due to the fact that we have lake effect here. We get these polar plunges where the heat pump will never keep up and it becomes less efficient and you just don't get the heat out of it.

This is why we always encourage a supplemented heat source. If you had a heat pump in your house, you'd have the heat pump side, which would look like an air conditioner, and your air conditioning coil inside, which gives off heat in the winter. You'd also have electric heat as your backup heat, or you'd have a gas furnace as your backup heat.

We call it emergency heat. This way, when it gets to a certain temperature, the electric shuts off, the gas kicks in, and it makes it more beneficial.

A good way to think of this backup or emergency heat is like a hybrid car. The hybrid car can run on electricity, but revert back to gas when needed. Same thing with a backup heating system when implementing a heat pump in your home. Working with an HVAC professional like M.N. Heating and Air can get your heating systems and backup emergency heat plan dialed in to ensure warmth in your home, even when the temperatures drop to freezing and below.

The benefits of the heat pump's efficiency will often outweigh the additional need of a heat source in those frigid days of winter.
