Thermostat Etiquette – Save Money AND Your System!
1) For non-programmable thermostats, try to employ a “set it and forget it” attitude with your thermostat. Between 72 and 74 degrees is optimal for heat pump operation. The less you change the temperature on the thermostat, the less the system has to work to match your request. When you do adjust the temperature, keep changes within an eight degree range (in other words, don’t move a thermostat from 74 to 64, as the unit will run a very long time to get the job done–money out of your pocket and strain on the system).
2) With programmable thermostats, setting a range of temperatures is fine, but keep the range within an eight degree split. Let’s use a thermostat with “Wake, Leave, Return, Sleep” settings as an example. Many of customers use the following settings, which use a six-degree split: Set the thermostat to have the home at 72 degrees when you wake, 78 degrees when you leave, 72 degrees when you return, and 74 degrees while you are sleeping. Most programmable thermostats (such as the Honeywell 8000 or Lennox’s iComfort) have an “intelligent recovery” feature, which allows the system to gradually achieve the various temperature settings. It will typically start working an hour before the desired temperature change time.
3) Keep in mind that one of the summertime functions of a straight AC or heat pump is to remove humidity from your home. Anytime you open a window, humidity can enter the home and send the system into work mode to get rid of it. It’s actually best to keep your home “sealed up” throughout the summer to keep your dehumidification working in an optimal fashion. Conversely, systems installed with a humidifer (highly recommended with any gas furnace) keep moisture in your home during the winter, and the same concept applies (although you are probably less apt to open windows in the dead of winter!)
