I had a heat pump installed about a year ago. It came with one free service and the installing company has been calling me almost every week to come out and do the complimentary tune up. I know that I obviously should take a free tune up, but it made me wonder. How often do I actually need this done? What are they actually “tuning up”?
Also not an expert in that field even if I am an electrician. As far as I know a heat pump is really just a way to say A/C unit that can also run in reverse. If everything is set up correctly it should probably just work and not need a service or “tune up” for a long time. It may just be that whoever installed the one you are using now wants to ensure that it’s working correctly and as it should. Or… They may be trying to find something to upsell.
Do they work well as an A/C replacement?
Yes…just don’t turn the stat to heat OR don’t hook up the reversing valve.
Heat pump and AC are literally identical machines with maybe 2 components being actually different. There’s honestly no reason AC only even exists.
