How often should I have my heat pump serviced?

You should have your heat pump serviced at least once a year. If you use your heat pump for heating and cooling, you should service it twice annually, in the fall and the spring.

What is the life span of a heat pump?

The average life span of a heat pump is 10-15 years. Because heat pumps run year-round to heat and cool your home, they don’t always last as long as a typical heating or cooling system. However, you can extend the life span by ensuring that your unit is routinely maintained by an HVAC professional.
