Why is My HVAC Leaking?

Common Causes of Leaks

When your HVAC is working perfectly, it is out of sight and out of mind. You simply turn the temperature up or down to set your comfort level and continue on with your day. Unfortunately, HVACs are technically complicated pieces of equipment and if not properly cared for and maintained, they can begin to cause problems.

One of those problems is a leak. An HVAC leak is a stressful, and often confusing problem to have. As an appliance which puts out cool air, you wouldn’t expect to see liquids dripping down the walls or off the drain line.

There are a few reasons why your HVAC could be leaking. Read on to discover what these reasons are and how you can avoid a mess of puddles in your home.

Clogged Drain Line

In order to cool your air, the evaporator in your AC must convert refrigerant from a liquid to a gas. This creates excess condensation which is removed from the area thanks to a drain line. Overtime, this drain line can easily become clogged thanks to dust and other debris. Such a moist area is subject to algae and mold growth as well.

All of this gunk then blocks the line, making it impossible for the excess water to drain and causing an overflow or leak. This is when you may need to clear the clog with a plumbing snake.

Keep the drain line clear with regular cleanings and you should suffer from leaks less frequently.

Leaky Drain Pan

Your drain pan also plays an important role in ridding the unit of unwanted, excess moisture. This constant exposure to moisture can cause corrosion and weaken the pan over time. If you have a leak, it’s a good idea to check out the drain pan for any cracks or leaks.

You may be able to fix it with a water sealant, or you might need to replace the pan entirely.

Clogged Air Filter

You’ll always hear our technicians preach that you must change your air filters on a regular basis. This is because many HVAC problems can be traced back to a clogged or full air filter. Dirty filters can restrict the airflow needed for the evaporator coils and cause them to freeze and eventually melt, drip into the drain pan and overflow.

Be sure to change your air filter at least every 3 months to avoid breakdowns and leaks.

Disconnected Drain Line

If your drain line doesn’t seem to be clogged, it could just be disconnected. Improper installation of your HVAC could lead to careless fittings, resulting in a loose connection which allows for leaks.

Low Refrigerant

Low refrigerant levels will lower the pressure in your system and cause the evaporator coil to freeze. Once it melts, it will drip and overflow the drain pan. If your unit is not cooling well or you hear hissing, you’re likely low on refrigerant and have a leak.
