When your Air Conditioner doesn't cool, it could be the result of:
Failed metering device
System is frozen (due to dirty filter or failed metering device)
Tripped safety switches
Low freon level in system
Water leak (Clogged drain)
Frozen systems require immediate attention by a trained HVAC technician.
Air Conditioners low on freon will cause the refrigerant temperature inside the evaporator coil to drop below freezing causing water on the coil to freeze into a block of ice. Frozen systems will not cool properly and may cause water damage.
Clogged drains can lead to serious water damage in your home and require immediate attention by a trained HVAC technician.
A clogged drain can be a major expense if not handled immediately. The water could spill over the pan and depending on where unit is located may damage your ceiling, walls and floors.
Both problems above should be immediately addressed to avoid damaging your system and possibly your home.
This could be from a clogged condensate, floor drain, or a humidifier if one is attached. Often times humidifiers are over looked and not serviced annually. This can cause the evaporative panel to become clogged and leak. Water heaters are also a prime suspect as they are typically sitting next to the furnace and can leak as well.
Water leaks in utility rooms and attics can cause major damage to your home. Contact an HVAC Professional to address leak issues immediately!
In the event of a water leak a professional should be contacted to diagnose and resolve the problem. Water leaks are a major source for property damage and insurance claims.
