> Assuming a heat pump lasts about 10 years Residential heat pumps are estimated to last 20-25 years; with typical services being capacitor changes, electromechanical contactors, and coil cleaning. Digital thermostats from 15 years ago prevent the most common compressor issues. Smart thermostats can now detect symptoms proactively. In the last 15 years, we've seen technological advances in compressor, gas, and electronics (as well as air to ground and air to water). And better calculations for sizing and air quality.
