I have lived in DC now for about 10 years. Every so often my family comes to visit and it is a great time. We go to museums and walk around the mall. This year my family came to visit during Christmas, right during a snowstorm! We still decided to go for a walk to check out the Monument and White House. We walked for a few miles and by the time we were done we were freezing. I love my house because I have installed the best heating and cooling systems. I love to have the air quality and temperature be just right. Needless to say when we got back from out walk in the snow and the heat was not working I was a little worried. I have a smart thermostat that I can turn on from my phone, and before we left I made sure it was on. I checked the thermostat when we got home and it was reading as hot, but it sure felt cold. I called my local HVAC provider and asked them if they could help me with the furnace. They told me that they had somebody available and would send them out to repair my heating. I was overjoyed that the HVAC company had someone that would come fix my heating. I really do have the best HVAC provider, they are better than anybody else I have ever dealt with in the heating and cooling industry. The HVAC technician told me that my heater needed to have yearly maintenance and that it should last about 5 more years.
