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”?
If you are set on not having someone look at it, at least take a look at your condensation line. It will be a PVC pipe coming off your inside unit and going to a drain. It probaby also has a u-shaped trap so that it can operate under negative pressure.
The issue is that algae can build up over time and cause water to back up and drain in places you don’t want. A service person doing a tune up would take of this task… But at a price higher than what you’d want to pay.
