My old Honeywell thermostat doesn't seem very reliable anymore since it had been used for many years now. I was using the old type of Honeywell thermostat models where i had to manually push the knob left or right to control the temperature. It looks something like this one:
I feel that my monthly gas cost bill was staying quite high because this heating and cooling thermostat wasn't very efficient in controlling the room temperature inside the house. Sometimes, it would show an inaccurate temperature and the heat wouldn't come on even though the rooms were starting to get cold. I thought it was the problem with the home heating gas furnace but i checked it out and it wasn't the natural gas furnace problem. Though i liked this particular old central heating thermostat and had used it for a very long time, i think it has lived out its usefulness now. I am not looking for a very expensive model of room thermostat where i can control room temperature through my smart phone using the smart thermostat app. I just need a simple and easy to understand programmable digital thermostat which does the job efficiently and hopefully last very long. The digital room thermostat should preferably work as a air conditioner thermostat, as well as a digital programmable heating thermostat. There are quite a few other top rated thermostat company to choose from but i like to see which one people will suggest.
