Even though San Diego has a climate most people in the US envy, we still experience extreme heat in the summer and unusually cold winter days. If you find yourself constantly looking at and adjusting the thermostat or being surprised by your monthly utility bill, it could be a sign that your thermostat is not working properly or at all. Emory Heating technicians will come to your home and assess the problem with your thermostat and either reprogram your system or replace your thermostat to operate when necessary to meet your comfort level.
