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.

Really nice honest guys. It was a pleasure to do business with a company that does exactly what they say theyre going to do! My basement was cleaner after they installed my new furnace and AC. Thanks again Greg and Grant and for doing such a great job.

5 star service!! I had twin tech install a high efficiency furnace and hot water tank at my home. I am taking time to write this review as a thanks for what I viewed as next level service that went above and beyond. Prior to installation they explained my specific options without pushy sales tactics and up front costs. Greg and Grant replaced a large portion of the duct work (built in their own shop) that had rusted over the years which resulted in a great looking job. It was a pleasure to work with people are passionate and take pride in their work. Following the installation they explained all aspects and maintenance of the new equipment. Products have worked flawlessly. Thanks again Greg and Grant! Highly recommend!!

Hi Dave, Thank You Dave for coming to my aid this past summer when my AC quit. Your men did a great job installing and cleaning the area. The unit is working very well and i would highly recommend your company TwinTech. Dave you delivered what you sold and i truly appreciate it.

My experience with TWINTECH has been excellent, start to finish. While doing market research I made a list of several local companies and called them for some high-level information. Dave was the first to call me back, and the only one to book a meeting to see my place in order to give an informed, accurate estimate. He reviewed the different AC makes and models with me, explained the technology, and made a recommendation appropriate to my home. The installation went smoothly. I had one post-installation issue there was moderate noise/vibrations coming from the duct system. I called about this, booked an appointment, and the technician resolved the issue during the service call. I feel assured having a 10-year warranty on parts & labour. I would recommend TWINTECH to anyone considering an AC or furnace for their home. Regards,

Dave and the guys from Twintech did a great job of installing my AC. They came on time did a nice neat job and cleaned up after themselves! Do not waste your time call Twintech first.

My AC unit was not working at all and our furnace that was still working but not giving us any trouble was over 15 years old. So I had 3 heating companies come out to give us a quote on replacing both the AC and the furnace at the same time. Two companies right away recommended that I replace both units simply because they were old. Dave from twintech however suggested that we save some money and replace the AC only because it seemed to him that the furnace was still in great shape and was running fine. He told us that he would have his technicians inspect the furnace thoroughly when they had it apart to install the AC. My husband was at home when the furnace was apart and was very impressed when the tech took him downstairs to personally show him that the furnace was in excellent working condition. He also cleaned the furnace at no extra charge. So now I have an honest heating and AC company that I can highly recommend to other home owners. Great job Thank You!

I had made the decision to replace my furnace and AC earlier this year. After meeting with several HVAC contractors I decided to go with Dave and his company. Dave was on time, polite, friendly and very professional. He took the time to answer all my questions and to explain the scope of work that would be required to do the job. The technicians arrived on time did a professional installation and completed the job on schedule. They respected my home by putting down vinyl runners to protect my floors and did a very thorough clean up. Im very pleased with my decision to go with Dave and his team. I would highly recommend them to anyone who is considering upgrading their furnace and air conditioner.

I have no problem in recommending Dave and the TWINTECH team to any home owner who is looking for quality heating and AC products and expert service.
