AC Won’t Turn On? Try These Troubleshooting Tips

Neffsville technician and homeowner checking a thermostat

The summer heat in Lancaster can turn on like a switch! But what happens if your air conditioning doesn’t do the same?

Check out these troubleshooting tips you can try if your air conditioning system won’t turn on before making a service call to an AC repair professional.

1. Head To Your Thermostat

It may seem like an obvious answer, but your first move should be to check the temperature you have set on your thermostat. It could be as simple as switching from the heat mode to cool mode, or the temperature setting might be too high to activate your air conditioning.

2. Check Your Filters

This is one of the most common and least expensive fixes for your AC woes.

Clogged filters restrict airflow, making your HVAC system work harder. It can also make it feel like your air conditioner isn’t working because it is not cooling your home as well as it should.

Check your filters for dirt and dust and follow the manufacturer’s recommendation for replacement. Homes with pets might need more frequent filter changes.

3. Clear The Landscaping

Your air conditioner’s outdoor compressor needs airflow to run. Make sure your shrubs aren’t crowding your compressor.

Leave about 2 to 3 feet of space between your compressor and your landscaping, and give your compressor about five feet of headroom between it and any trees above it.

4. Look for Blown Fuses

A power surge, which sometimes happens during peak summer electrical demand, can cause your circuit breaker to trip.

Check your home’s main circuit breaker to see if a breaker is in the halfway position. If it is, move it to the off then on position and watch to make sure it doesn’t return to the off position. If it does, then your unit is drawing too much electricity.

5. Remove Drain Line Blockages

Your AC removes the condensation it creates via a drain line, but a clogged drain or full drain pan can trigger your system to shut down. Check for blockages and remove them with a simple drain snake.
