What Causes My AC to Leak?
Posted On: March 12, 2024
An air conditioner (AC) leaking water can be caused by various issues. Here are some common reasons:
-
Clogged or Dirty Air Filter: A dirty or clogged air filter can restrict airflow, causing the evaporator coil to freeze and eventually thaw, leading to water leakage. Regularly changing or cleaning the air filter is essential for proper AC function.
-
Frozen Evaporator Coil: If the refrigerant levels are low or if there is a problem with the airflow, the evaporator coil may freeze. When it thaws, excess water can overflow the drip pan, causing leakage. Low refrigerant levels could indicate a leak, so it's important to address this issue promptly.
-
Blocked Drain Line: The AC unit has a condensate drain line that allows the condensed water to flow outside. If this line becomes clogged with dirt, algae, or debris, water can back up and leak into your home. Regularly cleaning the drain line can prevent this issue.
-
Improperly Installed or Damaged Drain Pan: The drain pan is designed to catch condensate from the evaporator coil and direct it to the drain line. If the pan is damaged or not installed correctly, water may leak. Inspecting and repairing the drain pan as needed is important.
-
Malfunctioning Condensate Pump: In some AC systems, a condensate pump is used to remove water from the drip pan. If the pump fails, water can accumulate and cause leakage. Check the pump for proper functioning and replace it if necessary.
-
Incorrect Refrigerant Levels: Improper refrigerant levels can affect the temperature and pressure in the evaporator coil, leading to freezing and subsequent leakage. A qualified HVAC technician should check and adjust the refrigerant levels.
-
Air Leaks in Ductwork: If there are leaks in the ductwork, warm air from outside can mix with the cold air inside the ducts, causing condensation. This condensation may lead to water leakage. Sealing any ductwork leaks can help prevent this issue.
If you're experiencing issues with your AC leaking, it's recommended to consult with a professional HVAC technician. They can accurately diagnose the problem and provide the necessary repairs or maintenance to ensure your system functions properly. Regular maintenance and prompt attention to issues can help prevent water leakage and prolong the life of your air conditioning system.

Fantastic team. Completed the job as per the specifications and in under 3 hours. Highly recommended Twintech.

During the summer, I previously hired TwinTech to replace my air conditioner when it failed. They did an excellent job so when I decided to proactively replace the furnace I contacted them. The furnace I had was 22 years old and showed signs of internal leakage. It still worked but rather than wait to have it fail in cold weather, I decided to purchase a higher efficiency model before it failed and take advantage of energy efficiency rebates. TwinTech offered very useful advice on the make and model of furnace to choose including high efficiency and variable speed motor. The price was reasonable, TwinTech arrived at the allotted time, installed the new furnace (including some re-routing of exhaust lines since the existing ones were too close to other vents), removed the old furnace, tested the installation and cleaned everything up. Overall, it was a good experience, they did a great job and the new furnace is working well.

Greg came over at 9:30pm to rescue my daughter and I from a horrible experience with Enercare that evening. He was professional. Kind. And got us what we needed quickly and at an afford price. I would 100% recommend calling on Greg and his team for any of your heating and cooling needs in the future!!

Installed a great hot water heater when our old one failed. When my furnace died during cold weather they showed up quickly and my house was warm before my wife got home. :)

I dont usually right reviews but when you receive service like this I felt it was a must. Honest and fair. I Have 4 children and on Xmas eve my furnace stopped working and a gentleman came out and got me up and running so at least we would have heat for the holidays. As promised he would replace my furnace early in the new year. The job was completed on time, great price for quality furnace and extremely clean and professional job. Would have never known anyone was in the house. Not a spec of dust or mess from lugging out an old rusty furnace. If you have any ac or heating concerns twintech is your only option. I was royally impressed with and Im sure you will be too.

This Company is terrific. No high pressure sales and they deliver exactly what they promise to deliver. The new furnace is great and we now get consistent temperatures throughout the house. The installers were great and very efficient and completed the work on schedule on the promised day. Everyone representing this company was very aware of their presence in our house and worked diligently to keep our home as uninterrupted and as clean as was humanly possible. We did not need to go around the house to clean up after they left, what a nice surprise. We have had follow up by the company to ensure everything is to our satisfaction. How unusual in today's environment. The impression left by Twintech is that they care about us and our home. This is so refreshing in today's high tech world. Out thanks go out to Dave in sales and G, G, and P (the installers).

The entire process was prompt and professional, from the initial quote to the installation of the new furnace. The team installed the new furnace and removed the old one in approx. 4 hrs. The guys were very knowledgeable and gave me lots of information. I have used Twintech before for a new A/C installation and new I was in good hands.

The overall experience dealing with this company was great from start to finish when getting a new furnace and ac this year. Everything was clearly explained to us during our consultation with Dave and there were no surprises with added costs. The work was done as expected and their response time to inquiries were very timely generally within a few hours or less. They are all very professional and was a pleasure to do business with them. Highly recommend to anyone looking for honest quality professional service.
