Are you having problems with the ductless AC system in your Corolla, NC, home? There are several reasons your mini-split is experiencing problems. Here are a few troubleshooting tips to help you determine what’s wrong and how to fix it:

Dirty Air Filter

The filter is the first thing you’ll want to check. If you haven’t cleaned your filter for a few months, it’s probably clogged with dust and dirt. You should clean the air filter for your ductless HVAC system once a month.

Incorrect Thermostat Settings

It’s also possible that your mini-split isn’t working because of a wrong thermostat setting. If you have a programmable thermostat, double-check to ensure the temperature setting is correct and not off by a few degrees. If that’s not the issue, contact your HVAC contractor for inspections.

AC Compressor Damage

If everything checks out and you still aren’t getting cool air, it’s likely that the problem is the compressor itself. A compressor may sustain damage due to a power surge or other issues. Have a service technician look at your mini-split and see if there’s any compressor damage.

Low Refrigerant Level

If your ductless AC system isn’t functioning, look for signs of refrigerant leaks. Refrigerant leaks are easily detectable with a simple eye check. Look for dirt or stains on the indoor or outdoor unit, specifically at the top.

Your mini-split won’t function properly if the refrigerant levels are low, so be sure to call a professional if you believe this is the problem. Refrigerant leakage is a serious issue since the liquid is harmful to the environment.

Dirty Outdoor Unit

If you’ve already tried all the steps above and your mini-split still isn’t functioning, it could be that the outside unit needs cleaning. Have a trained service technician do this to avoid any damage from do-it-yourself repairs and maintenance.

When your mini-split isn’t cooling, there are several things you can look at to find the problem. If the issue persists, you may need to hire a service technician to diagnose and repair it. For quality HVAC services, contact North Beach Services Heating and Cooling.
