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.

We couldnt have been more impressed with Twintech - from our first service call with Mitch who took the time to thoroughly diagnose the issue with our furnace, to Dave who proposed a well thought out solution to meet our needs and finally Greg and team who acted quickly to install given we had no heat.
We did our due diligence by soliciting quotes from alternate providers and were shocked and disappointed by the aggressive and manipulative tactics used.
Twintech was honest in their approach, detailed in their product knowledge, reasonably priced, diligent in their follow-up and valued our business.
Well done Twintech! You made this a positive experience for us and our new furnace works beautifully!

We recently purchased an Amana high efficiency furnace and humdifier through Twintech. The work was completed very professionally and the quality of the workmanship was high. There was some additional sheet metal work required to complete the installation, which they were able to complete themselves. Overall I am very pleased with the work and would highly recommend Twintech for a furnace replacement.

The blower on our furnace stopped working leaving us with a cold house. Dave from TwinTech responded immediately to our HomeStars service request. From beginning to end Dave was nothing but helpful, friendly and professional, he did a great job of walking us through the quote and scope of work.
The replacement of the furnace went smoothly. The Guys did a great job, everyone was very friendly and polite. There were no hiccups, or unexpected costs. The only surprise was they left the work area cleaner than it was before they started.
Was a great experience with the whole TwinTech team. Its been a couple of months since the new furnace has been installed and its working great!

I heard about TwinTech when researching new furnaces at furnaceprices.ca. After contacting them about my broken down furnace, Dave came to my house the next day to assess my situation and requirements for a new furnace. He recommended one that had stainless steel heat exchangers which sold me since my previous furnace had issues with a rusted secondary heat exchanger that had to be replaced. Dave also set me up with an appointment with an energy audit company so that I could take advantage of a rebate to help improve the energy efficiency of my home and get some money back. A few days later, Greg, Grant, and Mitch came to install the new furnace and remove the old one. When delivering and removing the furnaces, they were very careful not to damage my floors and walls, and even laid out red carpeting to protect the floors. They were very friendly and professional. The installation was completed in the time they said it would take and they cleaned up their work areas. Within a week, Dave called to follow-up to see how everything was going. I have already recommended them to several friends and family members who may need new furnaces soon.

Twintech did a great job, from Dave the Sales Rep to the Office staff and The Professional Technicians who did the installation. They were professional, courteous, knowledgable and informative. From beginning to follow up we were completely satisfied with everything. Thanks Again. Sincerely The Laytons

Great product, great service, great follow-up. The Twintech Heating and Cooling arranged removal of my existing oil tank and they installed the new gas furnace Amana (made in USA). I am very happy with the final result and support I received throughout the process. My thanks go to the entire Twintech team for their professionalism, great communication and follow-up.

We've had Twintech provide us with work in the past, for an inground pool heater and required rough-in for a new gas stove. More recently they provided the same friendly, professional, timely and clean installation of our new furnace.
