3 Reasons an HVAC Unit Is Leaking Water
When you own a business, maintaining the proper temperature is important for the comfort of your customers as well as your staff. So, when your HVAC system shows signs of wear, including leaks, you may find yourself concerned. Before contacting your
HVAC contractor, learn what causes HVAC leaks in the guide below.
Why Is the HVAC Unit Leaking Water?
1. Drain Line Clogs
When your drain line becomes clogged, it backs up, filling the drain pan. Because it can only hold so much liquid, eventually it overflows, leading to leaks. Routine maintenance by a licensed HVAC contractor can help prevent this by blowing out the lines that typically get clogged with dirt, reducing buildup.
2. Dirty Air Filter
Air filters are the first line of defense in your HVAC system, designed to capture airborne contaminants such as dust and debris before they enter your system. When not changed regularly, air filters can become bogged down, blocking airflow to the evaporator coil.
When this happens, the evaporator coil freezes over, then eventually melts, overflowing the drain pan and creating leaks. To avoid this, check your air filter every one to three months, replacing it as needed.
3. Disconnected Drain Line
Drain lines can become disconnected when the hose loosens over time or, more commonly, when the PVC fittings aren't properly secured during the installation. When the drain line becomes disconnected, condensation can build up, leaking through the ceiling or pooling on the floor. An HVAC contractor will check your drain lines to ensure they're secure, updating the fittings and replacing loose hoses if needed.
