What Causes My AC to Leak?

An air conditioner (AC) leaking water can be caused by various issues. Here are some common reasons:


  1. 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.


  2. 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.


  3. 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.


  4. 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.


  5. 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.


  6. 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.


  7. 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.

by Lousan, Ajax on Twintech Heating and Cooling

From quote, to installation, to follow up, Twintech provided excellent service. I would highly recommended their services.

by John, Pickering on Twintech Heating and Cooling

I had a really great experience with these guys. The salesman Bob was clearly very knowledgeable about everything to do with heating and cooling a home, spent a lot of time with us going over the details of the job, never rushed us and came back after the install to make sure we were happy. The installation crew was excellent, they covered the floors all the way from outside down to the basement furnace room, kept the place clean, got the work done on time and we’re very friendly. I’ve got 15 years in the contracting/ construction industry and these guys are one of the most professional company’s I’ve dealt with. Great company!

by Debra Robertson on Twintech Heating and Cooling

Had great service and clean-up was good. Was happy with my salesman. They were very friendly and helpful. I needed a new furnace as our was over 20 years old. The furnace and air-conditioner work great and they are very quiet. I am very pleased with the service and product I received.

by Private User on Twintech Heating and Cooling

Met with Dave for the sales process and he was great about explaining and going over everything to us. The install happened very quickly and the team were super professional and friendly. We are very happy with this company and their services and we definitely recommend them to others. Thankful my sister recommended them to me!

Reviews for Twintech were good, and they did not disappoint. After an initial visit to discuss the suitable AC unit for replacement, an installation date was available in just a couple of days, and everything was installed without a hitch. Highly recommended

by Private User on Twintech Heating and Cooling

Very pleased with the installation of our new furnace and A/C unit. From quotation stage to the completion of the job Twintech was very professional.
Thank you for a job well done.

by Darren, Pickering on Twintech Heating and Cooling

My old water heater quit on me. I called TwinTech. In less than 4 days, I had my new water heater installed and the old one taken away. The whole process was quick, easy, pleasant, and well done. This is the third time I've dealt with TwinTech and I've been satisfied each time.

by Private User on Twintech Heating and Cooling

I had them replace my furnace last year. When it came time for the air conditioner this year, I did not hesitate to call Twintech again. I will also have them perform regular maintenance on them.

by Robert, Ajax on Twintech Heating and Cooling

We required a new HVAC replacement after running the old
system for 18 years.
Dave understood our requirements and gave us a quote that
covered all the necessary items.
Installation was fast and very tidy. Everything works as
it should. Our thanks to Greg, Mitch and others for their
excellent work. Recommend this family owned business to
anyone else, considering HVAC or other work.

by John Armstrong, Pickering on Twintech Heating and Cooling

I needed a new furnace and A/C to replace my 21 yr. old units, and went to the internet to view potential companies in May, I received 3 quotes,
and chose Twintech based on their salesman Dave who was very detailed and covered off everything on what Twintech was all about,
an extremely dedicated company with so many years of experience, and after reading the on line reviews I was sold on Twintech, who did not disappoint as the installation team were top notch with Greg leading,
I would highly recommend this company without any doubts, in my books they are first class all the way. Our new Amana furnace and A/C are working perfectly !
