How a Heat Pump Cools Your House

In Indianapolis, heat pumps can be a popular solution for heating and cooling your home.

They seem almost like an air conditioner. In reality, they run in the same way during the summer. Due to a reversing valve, they can shift warmth in the opposite direction as well as add warmth to your home when temperatures drop.

Not sure if you rely on a heat pump or an air conditioner? Just locate the model number on the outdoor unit and check it online. If you find you have a heat pump, or you’re thinking over purchasing one, discover how this HVAC unit keeps houses comfortable.

How Heat Pumps Operate

Heat pumps use a refrigeration system similar to an air conditioner. Most can operate like a ductless mini-split, because they can heat and cool. Heat pumps use an indoor evaporator coil and an outdoor condensing coil. Refrigerant is pumped through these coils to shift humidity. The outdoor unit also uses a compressor and is encircled by metal fins that work as a heat sink to help shift humidity properly.

Summertime Cooling

When your heat pump is set to cooling, the refrigerant starts in the evaporator coil. Air from within the house is set over the coil, and the refrigerant extracts warmth. Water in the air also condenses on the coil, falling into the condensate pan below and flows away. The resulting cool air moves through the ductwork and back into your residence.

Meanwhile, the refrigerant passes through a compressor on its way to the outdoor coil. This constricts the refrigerant, forcing it to get hotter. As it goes through the condensing coil, the exterior fan and metal fins help to emit heat to the outdoors. The refrigerant moves back inside, moving through an expansion valve that cools it greatly, preparing it to start the process all over again.

When your heat pump is replaced and maintained appropriately, you’ll have efficient cooling equivalent to a high-performance air conditioner.

Wintertime Heating

When your heat pump is heating, the heat exchange process happens the other way around. By traveling in the opposite direction, refrigerant extracts heat from the outdoor air and adds it into your residence to warm the inside.

Heat pumps operating in heating mode are most effective when the temperature is above freezing outside. If it gets too frigid, a backup electric resistance heater starts to keep your residence cozy, but your heating bills rise as a result.

Heat pumps are on longer than furnaces because the air doesn’t become as hot. This helps maintain a more balanced indoor temperature. Additionally, because heat pumps shift heat rather than creating it from a fuel source, they can perform well above 100% efficiency. You can anticipate 30–40% savings on your heating bills by installing a heat pump.
