If you’re looking for a more environmentally friendly way to heat your home, there are few systems that offer better than a heat pump. These energy-efficient devices use the refrigeration cycle to mechanically transfer thermal energy, either by extracting it from the air (in heating mode) or from the ground (in cooling mode). Heat pumps are a lot like central AC systems: there’s an outdoor unit and an indoor one, both with aluminum fins and coils to release or collect heat, connected by a refrigerant line that transports energy between the two units.

The compressor, which is in the outdoor unit, pressurizes the working fluid, also known as a refrigerant. This causes it to vaporize and absorb heat from the air or ground in warm temperatures. The refrigerant then moves back to the indoor unit, where a fan blows air over the coil or tubes to cool the fluid again. The refrigerant then evaporates into its saturated vapour state and the process is repeated.

However, they are less effective at low temperatures and need to be combined with furnaces in colder regions.

Because they only use electricity for power, rather than to generate heat directly, heat pumps emit fewer greenhouse gases and other pollutants than traditional HVAC systems. In fact, they can often reduce your carbon footprint by two to five times.

Compared to fossil fuel-powered heating systems, they are also far more efficient, producing two to five times more heat energy for every unit of electricity used to operate them. This makes them a great choice for homes with rooftop or community solar or for those who want to be carbon neutral.

A heat pump is a more cost-effective option than other fossil fuel heating systems, and you’ll save even more money by pairing them with solar panels for maximum efficiency and savings. Plus, many states and utilities offer rebates and other incentives for people who choose to install them.

To make sure you’re getting the best system for your needs, always find a qualified professional to install it. Ask for recommendations from family members and friends, or check with local green-energy resource groups to see if they have any preferred contractors. The heat pump manufacturers Carrier, Daikin, LG HVAC, and Mitsubishi / Trane all have preferred partnerships with independent contractors that meet their ideal standards for installing their products. These contractors can give you a better warranty and ensure your system is running at its peak performance. They’ll also likely be more familiar with your local climate conditions and know how to best work with the technology in your area. That way, you can rest assured that your new heat pump will keep you and your family comfortable for years to come. In a city or state with strict energy efficiency requirements, heat pumps are your best bet for staying compliant.
