Answers to The Most Common Heat Pump Questions

What is a heat pump and how does it work?

A heat pump is a mechanical system that uses a refrigerant to transfer heat from one location to another. In the winter, a heat pump can extract heat from the outside air and transfer it inside to heat a building. In the summer, it can do the opposite and remove heat from the inside of a building and transfer it outside to cool the building.

How efficient is a heat pump compared to other heating systems?

Heat pumps can be very efficient, especially when compared to other heating systems like electric resistance heaters or fossil fuel-based systems. In the winter, a heat pump can be up to 300% efficient, meaning it can produce 3 units of heat for every 1 unit of electricity it consumes. In the summer, a heat pump can be up to 600% efficient, meaning it can remove 6 units of heat for every 1 unit of electricity it consumes.

Do heat pumps work in cold climates?

Heat pumps can be used in a variety of climates, including cold climates. However, their efficiency may decrease as the temperature drops. In very cold climates, it may be necessary to supplement a heat pump with another heating source, such as heat strips, to maintain comfortable temperatures inside your home.

How much does it cost to install a heat pump?

The cost to install a heat pump will depend on a number of factors, including the size of the building, the type of heat pump being installed, and the complexity of the installation. On average, the cost to install a heat pump ranges from $11,000 to $15,000. However, typical incentives for a heat pump are $10,000 from Mass Save and $2,000 in federal tax incentives, which brings the cost down considerably.

How long do heat pumps last?

Heat pumps can last for many years with proper maintenance. The expected lifespan of a heat pump is usually around 15 to 20 years.

Can heat pumps be used for both heating and cooling?

Yes, heat pumps can be used for both heating and cooling. In the winter, they can extract heat from the outside air and transfer it inside to heat a building. In the summer, they can remove heat from the inside of a building and transfer it outside to cool the building.

Do heat pumps require a lot of maintenance?

Heat pumps require some maintenance to ensure they are functioning properly and efficiently. This may include cleaning or replacing the air filters, checking the refrigerant levels, and having the system inspected and serviced by a professional. It is important to follow the manufacturer's recommendations for maintenance to ensure the heat pump is operating at its best.

How loud are heat pumps?

Like any mechanical system, heat pumps can produce some level of noise during operation, typically measured in decibels (dB). According to the National Park Service, a typical conversation between two people occurs at a noise level of about 60 dB. By comparison, a heat pump operating at full capacity may produce a noise level of around 50 dB, which is similar to the noise level of a washing machine.
