Air Conditioning Troubleshooting
What do you do if you realize your AC is not functioning properly?
Quality West is happy to provide you with several tips that can possibly help you avoid a service call if you discover only a minor issue with your AC system. However, most of the tips listed are only temporary solutions and it is highly recommended that you follow up with a professional to ensure the proper operation and safety of your system.
DIY Steps for Troubleshooting
- Check the Thermostat. The first thing to check is the thermostat, which governs the automatic operation of the furnace. Check to make sure the batteries in the thermostat are working. If the controls or dial is set to a lower temperature that the thermostat is showing, set the control 5 to 10 degrees higher than the the indoor temperature displayed. If the thermostat has a timer, see that its settings allow the furnace to be on at the time you are checking it. Making these adjustments may start the furnace.
- Check the power switch. If the furnace still won’t power on after checking the thermostat then check the switch governing the power to the furnace. Most resemble ordinary wall switches and can be switched off inadvertently. You can find the switch in the furnace room on the wall near the furnace. Returning the switch to the “on” position should restart the furnace.
- Check the breakers for your AC system. There will be one for the indoor furnace unit and an additional one for the outdoor condensing unit. If one of them has been tripped, it can easily be reset by first moving it to the OFF position and then back to the ON position.
- Check the lower section of the furnace to see if it is very cold and sweating. If so, turn the air conditioner off for at least 4-5 hours and replace the filter. The unit is frozen and will need to defrost.
- NOT GETTING ENOUGH AIR FLOW: Check the furnace filter and replace or clean if dirty. If the filter is very dirty, it could be restricting the air flow of your system. Once you change the dirty furnace filter, follow these steps to attempt to restore the air flow: 1) Turn your system “OFF”. 2) Turn the fan to the “ON” position, and allow to run for 2 hours. 3) After 2 hours, turn the system to “COOL”, and the fan to “AUTO”. If the filter was the only problem, your system will likely return to it’s normal air flow.
