Noticing a leak in your commercial HVAC system is a major concern, but it doesn’t mean you have an emergency on your hands. In fact, minor leaks are fairly normal. While they shouldn’t go unaddressed, there’s usually a simple explanation. Knowing what that explanation might be will help your equipment last longer and function more efficiently. Below are some of the most common reasons why your HVAC might be leaking.

Common Causes of Leaks in Air Conditioners

1. Cracked, Damaged, or Missing Drain Pan

Manufacturers of commercial HVAC equipment know to build their equipment with moisture in mind, which is why drain pans are an integral part of any AC system to catch excess water. If these drain pans are damaged or missing, condensate from inside the system won’t have anywhere to go. You can use a wet and dry vacuum to clean up excess moisture, and if your drain pan is lost, a replacement can be found relatively easily through a trusted HVAC supply specialist.

2. Condensate Drain Lines Clogged or Blocked

A major part of a commercial HVAC system is set up to redirect water. The condensate line is a key component to quickly carry moisture out of your equipment. Because the water in HVAC equipment often carries dust, dirt, or rust, this debris can gradually deposit inside the drain line, causing it to become clogged or even blocked altogether. You can solve this problem by occasionally rinsing the condensate line with diluted vinegar and vacuuming out the blockage.

3. Dirty Air Filters

One of the most frequent problems with any air conditioning system is also one of the simplest to diagnose. A commercial HVAC system is only as reliable as the filters it has, and if the filter is dirty or defective, it can restrict the airflow over the evaporator coils inside. This causes the coils to run too cold and freeze. When they thaw, the water pools and leaks.

Remember to change your air filters regularly, depending on the type of business in question. Generally, restaurants should change their filters every four to eight weeks, while retail businesses should do so roughly every 12 weeks.
