Simple Things You Can Do Before Determining You Need A Technician
AIR CONDITIONING TROUBLESHOOTING System not running:
Check your Thermostat. Make sure the control is set to Cooling mode. Make sure your set temperature is cooler than the current indoor temperature. Is the thermostat working? It might need new batteries. If the system does not kick on after setting the temperature, check the next steps.
Check the outdoor condensing unit. If it is not running, take a look at your circuit breaker or electrical panel in your home. Make sure everything is in the ON position.
Check to see that the main power switch on the outdoor unit is in the ON position. The power switch can be found usually mounted on the exterior of the house, just a few feet away from the unit.
Is the blower motor in your furnace or air handler’s fan coil running? If the system is set for cooling, the blower motor should be running. If not, check to make sure your indoor unit switch is in the ON position.
HEATING TROUBLESHOOTING System not running:
Check your Thermostat. Make sure the control is set to Heating mode. Make sure your set temperature is warmer than the current indoor temperature.
Ensure that your furnace’s or air handler’s power is on. Try turning the fan to ON using the fan switch on the control or thermostat to test for power to the furnace.
Make sure all circuits on your electrical panel or circuit breaker are in the ON position.
Check the furnace power switch to be sure it’s in the ON position (it looks like a light switch on a gray box located at the furnace).
Make sure that nothing is blocking the exhaust to outside (e.g. snow).
UNDER-PERFORMANCE ISSUES FOR HEATING/COOLING SYSTEMS:
Check the filter for buildup. If you have one-inch thick furnace filters, a once-a-month change is recommended. Two-inch-thick filters—and other high-capacity pleated filters—usually only need to be changed every other month or less, depending on the type. If you don’t change it, the filter will eventually become so full, it will block the proper airflow and strain your furnace.
Check all return air grilles to make sure they are not blocked. Return air grilles are larger and are located on a wall or the ceiling in newer homes. Older homes frequently have return air grilles on the floor.
Check all supply registers to make sure they are open and blowing air.
