I just recently bought a smart thermostat for my central heating and air conditioning system. The smart thermostat was easy to instal. However, I am having some issues working with the thing. I do not understand a lot of the features of this smart thermostat and I also do not understand completely how to use the app on my cell phone that controls the smart thermostat and my central heating and air conditioning system unit. So what did I decide to do? I decided to call my local heating and air conditioning company to speak with one of their most certified heat and a/c specialists to help me with the brand new smart thermostat I just bought. They were willing to help me over the phone for free because I bought the smart thermostat from the local heating and air conditioning company. Had I not bought this smart thermostat from this local heating and air conditioning company, they would not have wanted to help me for free over the phone! So that is the major benefit of buying a smart thermostat or any kind of heat and a/c equipment from your local heating and air conditioning company. You will always have good customer service and assistance from your local heating and air conditioning company if you buy everything from them. My heating and air conditioning specialist that I spoke with over the phone really was able to help me with this brand new, up to date and pretty nice smart thermostat that I bought from them thankfully!
