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.

Dave was very pleasant to deal with and Twintech responded quickly when our furnace needed to be replaced ASAP. Installation was done on time and the crew were neat and tidy. We now have a great furnace that suits the needs of our family.

When your furnace kicks in over the holidays and you're not sure where to turn.. I'm so thankful that this company returned my phone call. I appreciated their transparency and clarity which allowed me to make an informed decision. With various quotes thrown at you, it can be difficult to make the right decision and trust the solutions offered by different companies. TwinTech spoke the truth and delivered on their word. Neat, timely and clean service; the peace of mind I needed during a very cold holiday season. I highly recommend them!

Pulling a old unit out and installing a modern heating system! Required drilling holes in the wall for the newer pipes. We went from 70% (I am willing to bet it was far less due to lack of maintenance and just old) to 96% newer . It now feels warmer and more pressure and we use to run extra heaters and feel as though they are not necessary!

I received three quotes before deciding to choose Twintech. Dave's prices was much more reasonable than the competitors. I most appreciated their honest recommendations. Others tried to oversell their products and services. Thank you Dave!

My 19 year old furnace stopped working when the cold weather hit in November, and I was left without heat. I interviewed several companies and found TWINTECH HEATING and COOLING to be very knowledgeable, quick to respond to my inquiries and very competitively priced.
Dave provided all of the information and pricing ahead of time and set up the appointment for the installation. Greg and Mitch arrived on time to do the installation and worked quickly and efficiently to complete the job.
After the completion of the installation, Dave followed up to ensure that everything was working well and that I didn't have any concerns.
Overall, this was a low-stress and flawless experience from start to finish. I would highly recommend TWINTECH HEATING and COOLING to anyone that requires a new furnace.

Our 20 year old furnace broke down during the first cold weekend this past November and our usual HVAC company never returned our phone call. Their loss, missing out on a sale since we didn't want to spend much fixing an old furnace and our 40 year old air conditioner was also long overdue for replacement. We proceeded in obtaining three different quotes for furnace and air conditioner replacement, and proceeded with the one we received from Twintech.
Dave was friendly, knowledgable and accommodating to our schedule and provided with us with a price that fell in the middle of the three quotes that we had. We felt that the Amana furnace and air conditioner he quoted us on were the best products and value offered to us and felt most comfortable with the professionalism and reputation of Twintech.
Greg, Grant and Mitch were at our house for installation the day after we decided to proceed. The guys were friendly and informative, the job was completed efficiently and workmanship appears excellent. Our house is certainly much more comfortable with the new two-stage variable speed Amana furnace compared to the old clunker! And, we're looking forward to enjoying the new air conditioner once summer rolls around again. Thanks Twintech!
