I consider myself lucky that I know how to do small repairs myself around my house.
Otherwise, I would be spending a fortune to call a professional every single time something breaks! This was the case when my smart thermostat that runs my central heating and air conditioning system broke the other day.
It was really an easy repair. The thing that was wrong with it was simple. The wiring somehow got disconnected from the wall and caused my central heating and air conditioning system to fully stop working. At first I almost called the local heating and air conditioning company to send out a certified heat and a/c specialist. However, once I did some trouble shooting I found that it was the smart thermostat that ended up being the issue. And somehow it got loose from its mount and a wire disconnected. Well, I went and got my rolls from the basement, took the smart thermostat out of the wall and then reinstalled it as if it was a brand new smart thermostat being hooked up for the very first time. This reconnected the disconnected wire and then my central heating and air conditioning system unit was fully working again along with the smart thermostat itself. I was really glad I did some troubleshooting so I could fix this myself. It would have cost at least a few hundred bucks to have the heating and air conditioning company send a certified heat and a/c specialist out to do the same thing that I did for nothing!
