Reasons Your AC Might Leak
Posted On: March 18, 2024
An air conditioning (AC) unit leaking water can be a sign of various issues. Here are some common reasons why your AC unit might be leaking:
-
Clogged Drain Line: Over time, algae, mold, and debris can accumulate in the drain line, causing it to become clogged. When this happens, water can back up into the unit and leak out.
-
Dirty Air Filter: A dirty or clogged air filter can restrict airflow over the evaporator coils, causing them to freeze and eventually thaw, leading to excess water that may leak from the unit.
-
Frozen Evaporator Coils: If the refrigerant levels are low or if there is restricted airflow, the evaporator coils can freeze. When the ice melts, it can overwhelm the drain pan and lead to leaking.
-
Cracked or Damaged Drain Pan: The drain pan underneath the evaporator coils can crack or become damaged over time, causing water to leak out of the unit.
-
Improper Installation: If the AC unit was not installed correctly, it may not be level. This can cause water to pool in certain areas and eventually leak out.
-
Blocked Condensate Line: The condensate line that carries water away from the unit can become blocked by debris or algae growth, causing water to back up and leak out.
-
Refrigerant Leak: A refrigerant leak can cause the evaporator coils to freeze, leading to excess water leakage when the ice thaws.
-
Dirty Coils: Dust and dirt buildup on the evaporator or condenser coils can insulate them, preventing proper heat exchange and leading to freezing and subsequent leaking when they thaw.
-
Over-sized Unit: If your AC unit is too large for the space it's cooling, it may cycle on and off frequently, leading to excess condensation and potential leakage.
-
Broken Pump: If your AC unit has a condensate pump to remove water, it could malfunction or break, causing water to back up and leak from the unit.
-
High Humidity: In extremely humid conditions, your AC unit may produce more condensation than usual, potentially overwhelming the drainage system and causing leaks.
Regular maintenance and inspection of your AC unit can help prevent many of these issues. If you notice water leaking from your AC unit, it's essential to address the problem promptly to prevent further damage to your system and your home.

On one of the coldest days of winter, our furnace stopped working. Our regular furnace company came and told us we had a CO2 leak and shut us off. Their quote for a new furnace was way too high and they couldn't even install it on the same day. TwinTech was recommended to us by a friend. We called and spoke to Dave who was very nice and knowledgeable. Grant showed up a short time later and a new furnace was installed the same day with no troubles at all. Best of all, we received a higher-end furnace than what was offered by our previous company and at a cheaper price. I would recommend TwinTech with no hesitation at all.

Great sales member named Dave came in told us some amazing items and how they would be priced installed an all. We couldnt believe it! The next day the ac was installed, that day one employee named Greg told us that our furnace was working way to hard and was causing us to use way too much gas. So two days later they came in an installed a new furnace!

They removed and discarded old furnace. Installed new furnace. Installed air intake pipe, that had never been installed by builder, no charge. Replaced loose hose on floor with hard pipe and rerouted it to drain, no charge. Almost 33% cheaper then quote from Enercare, which was the company we dealt with and had insurance with for 8 years. No yearly fee for cleaning/insurance, saves 300 a year. Courteous, professional, fast, and friendly. My wife and I have been recommending them to everyone we know and meet, and will continue to do so. Thanks for everything, Twintech!!!

Finally! An honest company with highly knowledgeable and informative staff. Had a furnace service and found multiply errors in our system from an amateur installer. Very fair price to correct problems and will definitely use again.
