What To Do If Your HVAC Is Leaking Water

Oh no. You’ve discovered your HVAC is leaking water. Now what do you do? Don’t panic, we’ve got you covered. It is common for leaking water to occur. So let’s look at what is causing it and what to do about fixing it.

Your refrigerant may be low. Refrigerant keeps the pressure from dropping in your HVAC system and can cause your evaporator coil to freeze. If this is the cause of the water leaking, other problems you may find are the AC is not cooling properly or there is a bubbling noise coming from the refrigerant lines. Call a professional to come measure your levels and refill your refrigerant and they check for a leak in the lines and they can fix it immediately.

You may have a clogged drain line. This is a very common cause for a leaking AC unit. If the condensate drain is clogged, you’ll have to clear the line. Try using a plumbing snake to remove
the clog, which could be built up mildew or mold blocking the way. You should keep your drain lines clear by doing regular cleaning with 1-2 cups of bleach or vinegar through the lines every
couple of months.

The HVAC drain pan might be leaking. The drain pan’s function is to collect water and direct it towards a drain. Due to the moisture exposure, the drain pan will degrade over time and will need to be replaced. Remove the standing water to examine the drain pan for holes or any cracks. You could use a sealant for minor cracks but you’ll need to replace the whole thing if that doesn’t work or if there are bigger holes or cracks.

The condensate pump may be broken. If the line is clear and the drain pan isn’t leaking, then take a look at the condensate pump. It could be malfunctioning or broken, and the water will build up and leak out of the HVAC. Call a technician to test your pump and replace if needed.
