Heat Wave – Why Is My AC Leaking?

The British summer has finally arrived, and while it could disappear as soon as it came, things are really hotting up around here.

We’re predicted 32C today, which is going to really put your cooling systems to the test!

Over the last week we’ve had an increased number of service calls, relating to air conditioning systems which are leaking water into the client’s premises.
On the cooling side of the AC system, the evaporator coil gets very cold. The idea is that warm air is passed through the evaporator coil, thus cooling the air down..which is then blown into the area you’re working in. This process creates moisture (much like the inside of your freezer).

The moisture that is created then has to go somewhere, usually outside of the building via a gravity or pumped drainage system.

The amount of moisture created can be exasperated by a number of things:

-) The refrigerant pressure in the evaporator is too low, causing it to get colder than designed and icing up
-) The air flow across the evaporator is restricted, for example because of a dirty filter or failed fan
-) High levels of ambient humidity

Anyway, this moisture has to go somewhere!

In summary, the water leaking from your ceiling area right now could be as a result of a number of different issues related to your air conditioning unit. Examples of these issues are

-) Blocked filters
-) Blocked coils
-) Blocked drainage system

There’s a pattern emerging! Water generally does as it’s told, and runs downhill (or if pumped, uphill). Problems occur when something gets in the way and the water starts to overflow!
