Your Air Conditioner Won’t Turn On

There are a few different solutions to an air conditioner not turning on, depending on what’s causing the issue. It could be as simple as a tripped circuit breaker—in which case, it’s just a matter of resetting the switch.

If your air conditioning still doesn’t work after that, it may be a deeper problem. Our techs know how to repair AC problems of all shapes and sizes and can help you get your system back up and running.

The AC Isn’t Blowing Cool Air

There are a couple easy solutions to fixing a unit that’s blowing warm air. One is to check your thermostat—it’s possible that it’s either turned off, set to warm instead of cool, or dialed to a temperature higher than what you’d like.

Another option is change your air filter. This part is designed to catch all sorts of airborne contaminants as air passes through, helping ensure your air is healthy. However, it can get clogged if not changed regularly, causing airflow and comfort problems. For best results, replace this filter once every three months.

There’s Ice on Your Air Conditioner

Here’s another common problem that can be solved by replacing your air filter. If it’s dirty, it can block airflow, causing the temperature of your system’s inner coils to plummet. Ice then forms on the coils and the system itself.

If left unchecked, ice can cause greater problems down the road, including expensive repairs. See if swapping out the filter solves the problem. If it doesn’t, you’ll likely need professional assistance, as it could be a problem with leaky refrigerant.

Your System Is Making Funny Noises

Air conditioners are supposed to make noise when they run, but if the standard hum turns into scraping, squealing, or rattling, it’s likely that something is wrong. The trick to finding a solution is to recognize the sound:

  • If your AC squeals, it’s probably an issue with the condenser fan or blower motor
  • Whistling usually indicates loose debris or clogs in the system
  • Rattling can mean a failing compressor or a problem with the starter

Rest assured that New Berlin Heating’s techs can help you diagnose AC problems and find the perfect fix.
