 Heat & Air THERMOSTAT SETTINGS Cooling: Do not set thermostat below 70 degrees, especially in mild weather. The indoor coil will freeze up after approximately two hours, resulting in no further cooling. Restaurants, bars, and businesses usually have special switches to cycle the system, allowing lower temperature settings. Heat pumps: Set thermostat no lower than 68 degrees, leaving the thermostat set at any temperature between 68 and 74 degrees costs no more than leaving it at 65 degrees. Once set, leave the temperature setting alone. Moving the thermostat up and down will cause "cold spots" in the home and may result in higher utility bills. Some of the newer heat pumps may produce a cost savings when set at a lower temperature. Heating: With high efficiency furnaces, the best comfort level and energy savings are achieved by leaving the thermostat set at one temperature day and night. Programmable thermostats work best on older less efficient systems. In most cases we do not recommend programmable thermostats that raise and lower the heating and cooling temperatures and adjust the cycle for the different days of the week. Some savings can be made but often to the detriment of the equipment and overall performance due to the fact that users tend to make the temperature changes too drastic. Note: Leave the system fan set to "on or continuous" setting all year round. This saves money and prevents hot and cold spots in the house. | Welcome to BIS | About BIS | Home Inspections | Get Started | Technical FAQ | Contact us |
