What to do if Your AC Unit Won’t Turn On

This entry was posted in Air Conditioning on by .

Uh oh! It’s hotter than a pistol outside, and your air conditioner isn’t turning on. This is the quintessential desert living problem that every Phoenix area homeowner dreads. Yet, before you get hot under the collar about it, there are a few tricks to try that may get your air conditioner back up and running.

  1. Take a Look at Your Thermostat – The first thing a repair person will do is check this, so you might as well check it first! You will want to make sure that it’s set to COOL and then lower the temperature setting by five or more degrees below the indoor temperature. You’d be surprised how often this solves the problem.
  2. Look for a Blown Fuse – A power surge or even too many appliances used at once can blow a fuse or trip a circuit breaker. First, check your home’s main electrical panel. In older homes, there will be a fuse box. Replace any blown fuses. On a circuit breaker, check for any sign of a tripped circuit and flip it to “on.” There may also be a shutoff box near your AC unit. If this fuse is blown, you will need to replace it to get your AC unit working again.
  3. Check Your Condensate Line – Air conditioners create condensation. Normally, this moisture is drained out via a drain line. However, it can sometimes get clogged. When it does, it can trip a safety switch that shuts off your air conditioner. You can attempt to unclog the drain line yourself by using a wet/dry vacuum to remove the blockage.
  4. Try Resetting Your Air Conditioner
    Some models of air conditioners have reset switches. You can try flipping this switch to see if it will kick your unit back on. If your air conditioner doesn’t have a reset button, turn off your unit at the thermostat and wait at least five minutes. Turn it back on again.
