Air Conditioning Contractor’s Tip: Ductless AC Troubleshooting

A ductless AC system is a great solution for all of your Palm Beach home cooling needs. But there will probably come a time when your system doesn’t work exactly as it should. For many types of ductless AC problems, you’ll probably have to call a professional air conditioning technician. But before you do, there are a few things you can check to make sure professional attention is really necessary.

If You Hear a Strange Noise:

Some sounds are part of normal ductless AC operation. If you hear a sizzling sound from time to time when your system is in heating mode, there’s no need to call an expert. The sound is simply related to the automatic defrosting of various system components. Similarly, a squeaking sound while your system is running often results from small changes in the size of the cover of the unit due to temperature changes.

If Your System Doesn’t Turn On:

There are several normal situations that can result in a temporary loss of function in your ductless AC system. For instance, if you turn your system off, you have to wait for about 3 minutes before turning it back on again. That’s because of a built-in safety feature of the compressor that’s meant to prevent shorting out a fuse but that can make it seem like your system is malfunctioning.

This same mechanism will kick in if there is any type of interruption in power to the system, so you should always give your system a good 5 minutes and try to turn it on again. If it still doesn’t start, it’s time to call for professional help.

If Your Heating or Cooling Is Inadequate:

Inadequate heating or cooling can be due to a number of conditions. These include dirty air filters, an improperly set or broken thermostat, or a blocked outlet port or intake grille. If you check all of these elements and correct them and your ductless AC still isn’t performing the way it should, call Envirotech Air Quality Services to get to the root of the problem.
