Failing Ductless System

Troubleshooting Tips for Your Ductless Mini-Split in Williamsburg, VA

June 12, 2021

If you use a ductless HVAC system to heat and cool your home, issues can happen unexpectedly. Before you call a service technician to perform emergency repairs, there are a few things you can do yourself to check for the cause of the problem. Here are some troubleshooting tips for your ductless mini-split in Williamsburg, VA:

Check the Circuit Breakers

If your ductless mini-split isn’t turning on at all, the first things you should check are the circuit breakers and power switches. This is a simple task, as all you have to do is find your breaker box and flip a switch to turn the breaker back on.

Check the Refrigerant

Your ductless mini-split needs refrigerant to work properly. While only certified service technicians can work with refrigerants, you can still visually check your refrigerant line for leaks. A refrigerant leak poses a threat to your indoor air quality because it can expose you to poisonous gas, so it needs addressing as soon as possible.

Clean the Filters

Another issue that impacts your HVAC system is dirty and clogged air filters. Air filters trap dust, pollen, pet dander and other particulates that otherwise would affect your air quality and HVAC efficiency. It’s recommended to clean the filter at least every other month during peak cooling season.

Clear the Drain Line

Your air conditioner creates condensation that drains through a condensate drain. However, the drain line becomes clogged occasionally, or the drain pan can develop a leak. When your drain line has a clog, it creates extra moisture that can damage your home.

Inspect the Wiring

Sometimes, your ductless mini-split develops an issue with the wiring. For example, improper wiring leads to poor signal reception or no reception to the mini-split. If you see an issue with your wiring, don’t fix it yourself. Contact a professional service technician for repairs.
