Air conditioning units fail in several ways. Knowing how to identify the cause of the failure will facilitate faster repair times so that your building doesn’t have to go without air conditioning for long. Some of the most common ways in which air conditioning systems fail are outlined below.
- Uneven cooling
Several problems can cause cooling from the AC unit to be uneven. A dysfunctional thermostat could be the cause. Your thermostat could either have malfunctioned or simply needs a battery replacement. Improper insulation can also cause uneven cooling. Consider using separate zoning systems for controlling the temperature in particular areas like the windows facing the sun.
- Clogged filters
Clogged filters can cause the AC unit to give out warm instead of cool air, or at worst, stop working altogether. Regular cleaning of the filters will ensure that they perform optimally for long. Scheduled replacement of air filters, instead of trying to squeeze more life out of an old air filter, also guarantees that your unit is breathing properly.
- Frozen coil
A frozen evaporator coil usually indicates that the airflow in the AC unit is not sufficient. When the air intake and filters are blocked by accumulated dirt or any other obstacle, airflow over the coil is blocked, resulting in the evaporator becoming too cold and freezing over. Heating such a coil causes it to drip water as it melts. Cleaning and changing the air filters on the AC unit will prevent this from happening.
- Leaking unit
The most probable culprit for a leaking AC unit is a clogged condensate drain pipe. This happens when the unit is old and needs replacement. The drain pan usually rusts with time resulting in leakage. A dirt filter also causes the evaporator coil to freeze over and drip excess water than the pan can hold when it melts. Regular maintenance or a complete overhaul of the system, in case of an old system, is usually enough to fix this problem.
- Unusual odor from the AC unit
Is there a musty, stinky smell emanating from the AC unit? The most common cause is a clogged AC system, which prevents fresh air from circulating. Stagnant water, as well as overheating components due to loose electrical fittings, could also be to blame. A damp environment within the unit usually results in the build-up of bacteria and mold, thereby producing a bad odor. Ensure that your unit is cleaned regularly to prevent this from happening.
