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”?
Never, do not let anyone touch it if it’s working. The furnace, yes…the outdoor unit, NO. Even then, the furnace would just need filter changes, and maybe checking gas pressures for heat and heat exchanger cracks or whatever…
It’s a closed loop system. Zero reason to even look at it unless it stops working.the more it gets worked on, the higher changlce it won’t be working the same after.
