Problematic HVAC System Leaks

Most of the time HVAC systems get overlooked and ignored while they work during the summer to keep you cool and during winter to keep you warm. If you check on your system from time to time, you might see some condensation gathering around the bottom.

Light condensation around your unit is typical of a working machine. If, however, you check and see puddles or small streams of water around your unit, you could have serious problems.

HVAC units should not leak significant amounts of refrigerant or water, and if they do, it points to a serious problem that needs to be addressed. Your unit can develop leaks over time and in this article, you’ll learn several causes for HVAC leaks and what to look for if you find puddles around your unit.

The Most Common Causes of HVAC Leaks

If your HVAC has begun leaking, there are several reasons why it might be doing so. A common source of leaks is a clogged drain line. Drain lines are installed so condensed and cooled water has a place to go.

If they become clogged with dirt, debris, mold, or mildew buildup, water can get trapped, back up, and form a leak. To solve this, the drain line needs to be flushed out and cleaned every four to six months.

Another common cause of HVAC leaks is dirty air filters. When an air filter gets clogged, evaporator coils are more likely to freeze. When it’s not in use, the coil will thaw and you’ll notice water leaking from the machine.

Finally, if you’ve recently had your unit installed and you’re experiencing leaks, water puddles could point to an installation problem. It may be necessary to have an HVAC tech come out to diagnose the issues with your unit.

How to Fix HVAC Leaks Properly

In order to get your HVAC unit running properly again, the issue behind the leak must be fixed. HVAC problems won’t go away on their own and will almost always get worse if ignored for too long. If your drain lines are clogged up, an HVAC technician will need to come and properly clean your lines of dirt and debris that is trapping the water.


They’ll also show you how to care for your lines by regularly maintaining them to keep them clear. If a unit has been incorrectly installed, a technician will be able to diagnose the area improper installation occurred and fix it according to protocol.

Finally, for dirty and clogged air filters, a technician can easily switch out an air filter for a new one and show you how to regularly maintain your unit by changing the filters every month.

Preventing Damage and Downtime

It’s always ideal to prevent leaks in the first place, and prevention always comes down to proper maintenance of your machine. If you regularly experience leaks due to your drain lines clogging, it’s essential to regularly clean them.

Check your drain pipes every four to six months, or on a more frequent basis if you find the problem continuing. Wash out your drain lines with a solution of half and half warm water and bleach to keep it clear of bacteria and mold growth.

Another easy prevention tip is changing your air filters on a regular basis. This will not only reduce the chance of your coils freezing but will help your entire unit run properly. Finally, regular maintenance and tuneups from HVAC professionals will ensure your unit runs at top performance.
