Why Won’t My AC Turn On?


This is the air conditioning problem you never want to run into during a hot Texas summer day: an AC that doesn’t turn on! Or maybe the fans come on, but the compressor doesn’t, and that means just circulating room temperature air around the house—which won’t do anybody in your house any good.

You may need to call for professional air conditioning repair in New Braunfels, TX because the AC has a malfunction that only an expert with the right tools can solve. When that’s the case, you can reach our team 24/7 and we’ll be out quickly to fix the trouble.

However, before examining the big malfunctions that may have caused the AC to stop working, there are a few simple checks we recommend you take. There may be a simple explanation for the problem.

The Thermostat

Always check on the central thermostat for the house when the AC isn’t turning on. This may seem too simple, but with advanced thermostats, it’s more likely for someone to have accidentally put in the wrong settings. Or for children to play around with the controls. Check to see that the thermostat isn’t set too high, and also make sure that it isn’t put in “fan only” mode.

The Circuit Breaker Panel

An air conditioning system uses large amounts of electricity: the compressor must put a heavy demand on its electric circuit each time it comes on. This might cause the circuit breaker for the air conditioner to trip and shut it down entirely. See if any breakers have tripped and reset them if they have. Try the air conditioner again. If the AC continues to trip the circuit breaker, please call for a technician.

The Air Filter

A clogged air filter can cause all kinds of problems for an air conditioning system, including forcing the blower fan to overheat and shut down. If you’ve just started using the air conditioner, the filter may be clogged from operating the furnace over the winter. Take out the clogged filter and put in a clean one. We recommend changing the filter every 1 to 3 months while the AC regularly operates to avoid future problems and drops in energy efficiency.

Problems you’ll need an expert to fix

If you’ve made the checks above and haven’t found a solution to your AC problem, now is the time to call professionals. There are a number of bigger malfunctions that could be at causing the problem.

  • Electrical board failure or other electrical problems. The majority of AC repairs professionals handle are for the electrical wiring and boards inside the air conditioner.
  • Burnt-out motors. If the fans won’t turn on at all, it may be a motor that’s burnt out and fused its wiring. A technician will need to replace the broken motor.
  • Failed thermostat connection. A thermostat uses different connections to activate the fans and the compressor. If one of them is broken, either the fans or the compressor won’t turn on.
  • Failed compressor. This is the most serious potential problem. A burnt-out compressor must be replaced. Often, it is more cost-effective to have the entire AC replaced rather than spend the money on just the compressor—especially for an older system.
