Air Conditioning Equipment Checklist
1. Is your thermostat in the “cool” position, and have you removed any tarps or covers from the outdoor unit, prior to attempting to start it?
2. Is your outdoor unit running? Check the breakers in the electrical panel (usually located in the garage, basement or other outside walls) Make sure they are in the “on” position for the breaker marked for the Air Conditioner or Heat Pump. Check the disconnect box (mounted outside at the unit, on the side of the house) make sure it is in the “on” position.
3. Is the blower motor in the furnace running? (If the thermostat is in the “cool” position, the furnace blower should be running.) If not, make sure the on/off switch at the furnace is in the “on” position. It looks like a light switch on the side of the furnace.
4. Have you changed your filter recently? A blocked air filter can most definitely be the culprit. Depending on family size and number of animals, recent remodeling or even refinishing your hardwood floors, changing your filter can be a quick and easy fix. 1” filters should be changed monthly, 4-5” filters should be checked at 6 months and changed if needed, but most likely will last a full year. Be sure that you have changed your filter in the furnace recently. If you noticed “ice” on the indoor or outdoor units along with your dirty filter, turn the system off, change the filter, allow the system to thaw and try to run it again the next day.
5. Check all supply and return air grilles to make sure they are not blocked by furniture.
Gas Furnace Equipment
1. Check to make sure that your thermostat is set in the “heat” position
2. Make sure that the temperature setting on the thermostat is set above (or higher than) the indoor temperature showing on the thermostat. Please note, some systems have a delay built in and heat may not start for 5 or more minutes.
3. Ensure that there is power to the furnace by checking the on/off switch located at the furnace (looks like a light switch), check the breakers in the electrical panel and you can also turn your thermostat fan setting from auto to “on” to see if the blower runs at all, even when there isn’t a request for heat.
6. Replace the furnace filter if needed, if a furnace is “starved” of fresh air from a blocked filter, it will shut down on safety. Turn furnace off, replace filter and retry. 1” filters should be changed monthly, and 4-5” filters should be checked at 6 months and changed if needed and definitely changed once a year. This is depending on size of family, number of pets, recent remodeling etc.
7. If the system is running but you have not changed your filter, the filter may need to be replaced.
8. Check all supply and return air grilles to make sure they are not blocked by furniture.
