4 Reasons Your AC Leaks Water and Their Solutions

The Drip-Drop Puzzle:

Air conditioning units are a godsend in beating the Southern Illinois area heat, but when they start leaking water, it can lead to a host of problems. Understanding why your AC is leaking may save you the headache and even bigger trouble. While you may discover your situation warrants the professional services of Merts Heating & Air Conditioning for an AC repair, Merts discusses the following causes of your AC leaking and what to do.

Four main reasons your AC leaks water:

1. Clogged Condensate Drain Line

One of the most common reasons for AC leaks is a clogged condensate drain line. Dirt, mold or algae build-up can block the drain, causing water to back up and leak into your home.

Solution: Regularly clean the drain line with a wet/dry vacuum. For stubborn clogs, or to just make it easy on yourself, call Merts Heating & Air Conditioning to schedule one of our trained HVAC technicians to clear the line.  

2. Dirty Air Filter

A dirty air filter restricts airflow over the evaporator coil, causing it to freeze. When the coil eventually defrosts, it can cause an overflow in the drain pan.

Solution: To prevent this, routinely replace or clean your unit’s air filter based on the manufacturer’s recommendations, typically every 1-3 months.

3. Low Refrigerant

Low refrigerant levels can cause the evaporator coil to freeze, which, like a dirty air filter, leads to an overflow when it defrosts.

Solution: Regularly check for signs of a refrigerant leak, like a hissing noise or reduced cooling capacity. If suspected, always call Merts for an AC repair, as handling refrigerant requires special training and tools.  

4. Broken Condensate Pump

If your AC unit is in the basement or some other area where normal draining cannot occur, it relies on a condensate pump to drain the water. A malfunctioning pump can cause the water to pool and eventually leak.

Solution: Regularly inspect the pump for any signs of damage. If it’s not working, call Merts for an AC repair or a condensate pump replacement.

Regular maintenance can prevent most AC leaks, but if you notice your AC leaking water, check for these common issues. Remember, when in doubt, it’s best to call the professionals at Merts Heating & Air Conditioning to avoid causing further damage to your unit.
