VWB Blog 1 year ago 2

Are you having issues with your home’s HVAC system? Stuffy vents, sporadic functionality, and clogs in the drains are all signs of poor quality. But a leaking unit is a sign of a different kind of problem entirely, and one that needs immediate attention.

HVAC units require a constant flow of water to perspire components and avert contamination. Water damage isn’t ideal in any circumstance, but with an HVAC unit, it’s especially hazardous.

If your HVAC unit leaking water and you don’t know how to deal with it, we’re here to help. Read below for all the information you need.

Possible Causes of the Leak

If your HVAC unit is leaking water, the first step is to determine the possible cause of the leak. Potential causes of a leaky HVAC system include a cracked drain pan and a disconnected or blocked drain line. A refrigerant leak or condensate pump malfunction may also be a cause of leaky HVAC.

Knowing the cause of a leaky HVAC unit is key to identifying the best course of action for fixing it.

Identifying the Source of the Leak

If you detect any standing water or discoloration, trace the water back to its origin. Begin by looking near the air handler or furnace for any build-up of water or condensation. Check the drainage pan beneath the unit to ensure it is not overflowing.

Check the condensate pump and drain line for signs of leaks, such as a stopped-up or clogged drain line.  Inspect the air supply and return vents for signs of water accumulation.

Also, inspect any flexible connections, such as ducts and hoses, for signs of blockage or seeping water. Identifying the exact source of the leak is essential, as it allows for the most effective means of HVAC repair.

Determining the Severity of the Water Leak

Once you’ve identified the source of the leak, check for tears, cracks, or loose connections in any of the pipes or hoses. Look for cracks in seals or gaskets near the compressor, which may be a telltale sign of age or improper maintenance.

If the issue is minor, you may be able to handle it on your own. If not, it’s best to contact this HVAC company to evaluate the situation and take the necessary steps to fix the problem.

Common Repairs for HVAC Unit Leaking Water Issues

If your HVAC unit is leaking water, there are a few common repairs that should be done to remedy the problem. If you find a faulty drain pan, replace it or seal it. If the drain line is disconnected, re-attach it or install a new drain line if necessary.

For a refrigerant leak, it may be necessary to call an HVAC specialist to inspect the system, as refrigerants can be hazardous to work with. Lastly, if the condensate pump is malfunctioning, try manual draining and pump replacement to alleviate the problem.

When to Call a Professional HVAC Technician

A leaking HVAC system usually indicates a serious issue, so it’s important to take action right away. Implementing the steps in this article can help remedy the issue of an HVAC unit leaking water and keep your system running efficiently.

If you notice water leaking from your HVAC unit, contact a professional immediately to inspect the unit and diagnose the issue. Taking action quickly can prevent further damage and provide peace of mind.
