When my wife told me that she was having a problem with the heating, ventilation and air conditioning system, I thought maybe she was exaggerating. She said that it had just stopped working. The first thing I thought was that the batteries in the thermostat had died. When I got home, I checked the thermostat and I even tried changing the batteries. It didn’t matter what I did, the thermostat did not do anything. The next thought that came to mind was that I hoped it was only the thermostat. When the HVAC tech arrived, he went right to the main thermostat. He concurred that it was definitely the thermostat. He sat down and started to talk about what thermostat we would like to have. We already had a programmable thermostat, but he started talking about a Smart Thermostat. My wife popped up and said the Smart Thermostat was her choice. He explained how the Smart Thermostat worked, and that we would be able to monitor the energy usage in the home. He told us that with the Smart Thermostat, it would enable us to be able to save money on our energy bills. I needed more information and that is when we could have it control the shades that were in the windows. The Smart Thermostat would have the ability to notify us, on our phones, if there was a problem with the HVAC system. After a couple minutes, we purchased the Smart Thermostat. He had me when he said that I could monitor the usage, and save some money.
