My first unscheduled maintenance call worked out OK

[Matt R.]

tl;dr: The thermostat broke, I fixed it.  Yay being a landlord!

I rented out my SFR nearly two years ago; the same tenants have been there the whole time.

The last time I went over for a regular maintenance visit, a couple of months ago, one of them asked me how often I had put batteries (2 AA) in the thermostat while I was working on the house.  I said maybe once a year, and they said that it seemed to be needing batteries every week or two.  They were putting really inexpensive carbon-zinc "Heavy Duty" AAs in it, instead of alkalines, so I put a couple of fresh alkalines in it, and gave them a few more to be used if needed.  That seemed to fix things until recently.

This past Saturday, I got a text at about 9 PM - the thermostat had power, but wasn't responding to the buttons, and (more importantly) was not calling for cool.  They asked if I could look at it Sunday morning, and I said yes, but that I could also come over that night if they wanted.  They agreed, so I put my tools in the car, bought a new thermostat, and drove over there.  During that process, I got another text, saying that they had managed to make it call for cool.

When I got there at 9:50, it was a little warm in the house, but not too bad.  I checked the thermostat wiring at the furnace and didn't see anything bad, so I proceeded to swap the thermostat.  It was about 10:15 when I set the clock on the new thermostat, and ran both the A/C and furnace (briefly) to make sure it worked.  The tenants were happy, so I cleaned up and went home.  I texted them Sunday evening to make sure it was still working, and they reported that all was OK.

The only real point I have is that this was my very first unscheduled maintenance call - everything else I've been able to take care of on one of my regular visits.  Can I apply for a merit badge or something from the Landlord High Council for this?  :D
