Today’s system controls are much more intelligent and sophisticated than the old on/off systems of the past. Temperature levels can be programmed to different settings for different times of the day or days of the week. Being able to change the indoor temperature settings depending on your schedule can lead to energy savings and lower utility bills. Some thermostats also monitor indoor humidity levels, outdoor temperatures, and filter efficiency. At Nail Heating & Air Conditioning, we can help you choose the system control that makes the most sense for your lifestyle and saves you money year round.
