The entire day, the heating and air conditioning system was all over the place. It would turn on and off randomly, would switch between heating and cooling and just in general was acting really odd. It almost made me think that my air conditioning system had come alive, but pushing the crazy ideas aside, I decided to look further into the issue. Then I spotted the problem, the smart thermostat that I had, had a blank screen. This was particularly frustrating, because that smart thermostat was only a month old, it should not be having problems. But here it was with a blank screen and not responding when I touched it. I didn’t want to deal with any problems it might have, because if it is always messing up after only being here a month, I didn’t want it. I called and explained my issue to the HVAC business where I bought the smart thermostat from. I was expecting them to say that it had been too long since I had ordered it, but thankfully they were very kind and understanding, and they sent out a new one free of charge. I sent them the old one that didn’t work, and once I had the new one installed all of the problems I was originally having with the heating and A/C unit disappeared. It was obviously the faulty thermostat. I am hoping that this thermostat is much better and will be working for a long time. I am just glad to have my furnace and A/C working normally again.
