Please take a few minutes to review the following checklist:

• Make sure the thermostat is set to either the heat or cool position
• Set thermostat to desired temperature
• Make sure the switch at the furnace is in the ON position by turning it off and then back on
• Check for blown fuses or tripped circuit breakers
• For air conditioning, check the outside disconnect to make sure it is in the ON position
• For heating, check that the gas shutoff is turned ON at both the gas line and inside the furnace
• For heating, check for snow, leaves, or blockages in the vent pipes
• If you have a flexible drain hose to the floor, make sure it is not plugged, kinked, or rolled up
