Your air conditioner has become an essential summer appliance, particularly with the ever-increasing frequency of severe heat waves nationwide. When the weather makes you sweat, your AC can too. Some of the moisture produced by your system is not a cause for concern, like the condensation draining from your outdoor unit during normal operation. However, larger amounts of water can indicate a problem. This is one of the most common service calls our air conditioner repair contractors see, and it can have many causes.
The filter in your air conditioner keeps the system and the air in your home clean, removing dirt and particulates from the air. Dirt from neglected filters can block airflow over evaporator coils, causing them to freeze, drip excess water, and overfill the drain pan. Clean or change the filter regularly, at least every 3 months – more often if you have children or pets – to prevent leaks and ensure optimal performance.
Mold, algae, dirt, or debris blocking your drain lines can cause AC leaks. Routine cleaning is an easy way to prevent this problem. However, if the damage is already done, you can remove the clog yourself with the help of a wet/dry vac or your friendly local HVAC repair technician.
If your HVAC system is newly installed and you’re experiencing significant leaking, you’re likely the victim of faulty ac installation. Drainage pipes that are not properly sized for the system or angled improperly can cause water to backflow or get stuck. If an installation problem is what’s caused your system to leak water, reinstallation by a trained professional is the only solution.
Low refrigerant levels can cause your evaporator coil to freeze, leading to an overflow of water in the drainage pan. A system that is not blowing cold air or hissing and bubbling sounds indicate a leak or low refrigerant. Contact a pro to identify and address the leak ASAP. If you wait too long, the operational stress put on your system could lead to the need for a new unit.
If your system is over 10 years old, the drain pan that collects condensation from the system can become damaged or rusted, resulting in leaks. Replacing the drain pain as soon as possible is best, but HVAC replacement is better. Not only will you fix your leak, but you’ll enjoy significantly lower energy bills, a more comfortable home, and the peace of mind that comes with a warranty that covers most major repairs.
