Heat Pumps

Even when you’re reaching for your winter coat, a heat pump will be able to extract heat from outdoor air to keep your home comfortable. Heat pumps work by moving heat energy from outdoor air into your home (or vice versa). To help you choose the best HVAC system for your home, our heating and cooling system contractors at A-1 Mechanical compiled a list of frequently asked questions we get from customers about air-source heat pumps.

Keep reading to learn how heat pumps help reduce energy bills so you save money in the long run. For more information, call your local HVAC contractor.


Heat pumps use differences in air temperature to heat and cool your home. Even the coldest winter air has heat energy. A heat pump uses a refrigeration system (similar to an air conditioner) containing a compressor and two coils. During the winter, liquid refrigerant in the outside coils extracts heat from the air and evaporates into a gas. From there, the heat energy is send to the indoor coils where it is used to heat your home. As the refrigerant cools, it turns back into a liquid. The refrigerant flows in the opposite direction in the summer to keep your home cool.


Mini split heat pumps can be installed anywhere in your home to create temperature zones. Like the name suggests, ductless heat pumps don’t need ducts to work, which makes them perfect for home additions out of range of your original heating and cooling system. A mini split system is also great if you and your family don’t always agree on thermostat controls. Ductless heating and cooling means you won’t have to shiver in your turtleneck and sweater while your kids complain how hot it is.


A heat pump system reduces the strain on your furnace and air conditioning unit while keeping your home at a comfortable temperature. By only using your furnace and air conditioner for supplemental heating and cooling, you’ll save money on repairs.

Unlike other home heating systems that convert fuel into energy, a heat pump simply moves heat from one place to another. Since heat pumps use less energy to heat and cool your home, you’ll start saving money on utility bills. According to, air-source heat pumps can reduce your winter energy bills by about 50% if you’re currently using a baseboard heater or electric furnace.


Yes. In fact, air-source heat pumps remove humidity better than central air conditioners. Part of what can make summers so miserable is the humidity that comes with high temperatures. Thankfully, a heat pump system is able to remove humidity so you can stay comfortable on even the muggiest days.
