I used to suppose everyone should have a maintenance plus service agreement, even though I recently changed my mind.
I still suppose they should have one, however you have to read it closely before paying for it; When I lived in my seasoned house, my hubby plus I always had a maintenance plan, and the Heating plus Air Conditioning dealer would do all our yearly maintenance, plus if there were repairs needed done, they would do it while doing the maintenance.
They would change the air filters when doing the maintenance. If something went wrong through the season, the Heating plus Air Conditioning dealer would send a tech out. My buddy and I would be top priority if my pal and I had an emergency. My buddy and I paid for none of the Heating plus Air Conditioning tech fees, however my pal and I had to spend money for the cost of the parts. This was a large savings for us. When my pal and I got a divorce, I obtained a smaller house. My buddy and I had no teenagers, so my pal and I split the home’s equity so my pal and I could both either get a nice apartment, or a small home. I called the Heating plus Air Conditioning dealer plus told them I wanted a maintenance plus service agreement for my Heating plus Air Conditioning equipment. They sent a tech over so I could look at the agreement plus sign for it. I assumed it was the same as the one my pal and I had, even though I soon found out it wasn’t, then once the maintenance plus minor repairs were done, I had no other benefits with the plan. I had to spend money for everything, plus they didn’t even put a up-to-date air filter in the A/C component or the furnace when they did the maintenance.
