Why Won't My Air Conditioner Turn Off?
Tuesday, May 05, 2015

Your heating and air conditioning should respond to custom control.

HVAC Troubleshooting

Setting the temperature with your heating and air conditioning unit is not a suggestion for the unit. When you set it at a certain temperature, you expect it to get there. Unlike many factors in our lives, indoor temperature regulation is not outside of our control. When a residential system isn’t responding appropriately to thermostat settings, you need to get to the bottom of the issue. The problem is there might be a dozen different explanations for why it isn’t maintaining your settings.

Here are some steps you can take to determine the problem:

  1. Get the simple solutions crossed off your list first. Checking the thermostat settings is a good place to start. Make sure the fan is set to “auto” and that the temperature setting hasn’t been lowered. If the fan is set to “on” it will keep blowing air continuously until removed from the “on” position.
  2. Still can’t get the air conditioner to shut off? Unlike heating units, cooling units don’t have a safety feature that shuts them off at a certain pressure point, so they could continue to run forever. This isn’t great for your utility bill. If this becomes an issue, you can always cut power by flipping the circuit breaker as a short-term solution. A bad thermostat connection could also be responsible.
  3. If neither of those options yields results, the problem could be a short in the unit wiring. This isn’t a disaster, but it will require the expertise of a qualified technician. Fiddling around with major appliances is best left to the professionals.

If you are tired of dealing with heating and air conditioning that just doesn’t measure up, get in touch with the pros at G+S today.
