When summertime arrives and the cooling season begins, air conditioning (AC) problems increase. Components that comprise the AC system that has been dormant during the heating season are abruptly put into service and why HVAC Maintenance is very important.
If latent problems exist, the jolt of being suddenly put into service will draw those problems to the surface. A very common problem that leads to homeowner distress is a frozen evaporator coil.
The evaporator coil is an air conditioning component located on the indoor unit associated with the furnace. You will find copper tubing connecting the furnace/evaporator coil to the outdoor compressor unit. Gaseous refrigerant moves back and forth between these two components.
The compressed gas expands in the evaporator coils and quickly cools. The cool air inside the chamber gives up the moisture it contains and cools dry air is distributed throughout the house by a blower. In turn, the gas heats up and the hot gas circulates to the outdoor compressor and gives up the heat it carries.
If the evaporator coil freezes, the refrigerant gas can no longer exchange heat and cold. The AC will stop cooling, even though there is a buildup of frozen water inside of the AC component. Several things can cause ice to form on the evaporator coils.
If the AC fails to cool and you open the unit and discover the ice buildup, it will require a repair visit from your HVAC professional. While the coil is frozen in a block of ice, the technician can neither diagnose the problem nor fix it. We recommend that you, the homeowner, thaw the ice on the coils before the technician arrives.
The AC will remove between 5 and 20 gallons of water from the average home. By the time you find the ice buildup on the coils, a significant amount of water will have frozen. Great care must be taken as the ice thaws—these are the procedures we recommend taking before you call a professional.
The sudden loss of AC cooling followed by finding the evaporator coil frozen in a block of ice is quite distressing. Armed with the information above you can take action to remedy the situation. Then give Northwind AC a call and allow us to put your AC system back in working order.
