Air con units have been known to develop some functional issues from time to time, and it is quite inconvenient to call your unit contractor every now and then. When an AC stops working in an office setting, this can render the place uncomfortable to work in, or maybe even unsafe when the temperature is fairly harsh outside. In this list are some of the things you should do and check if your office air con unit suddenly stops working:
Filters
When the filters become dirty, the unit will not work properly. The air con can blow air but not cool or get any air flow at all. The blockage of filters with dirt and debris may cause other serious problems such as the evaporator coils freezing and clogging. Clean the filter with a soft brush, mild soap, and water and see if the air con works after this. Do this regularly to avoid these kinds of problems in the future.
Electrical Panel
A tripped breaker or a blown fuse can sometimes be the root cause of the problem. This can be pretty obvious when other appliances and electronics in the office have issues working. Problems like these arise due to improper installation or old age of the air con unit since the air con electrical features might be a little tricky and can mess up other connections in the establishment. To fix this overall problem, have your fuse replaced or your breaker fixed by a qualified professional.
Thermostat
Despite being connected properly to the power supply, there are instances where the unit still does not work. A problem with the signaling from the thermostat could be the culprit. It can be as simple as adjusting the thermostat setting or replacing its batteries. A faulty thermostat renders the whole unit faulty, too, since it is the main part that tells the whole unit how hard it should work to get the desired temperature.
Wiring
Check the outside connections for burnt, broken or corroded wires. One indication of this problem is when the air con just stopped working out of nowhere or took a good amount of time before it powered up in the past. If the external wires are okay, then the internal wires might have a problem. Have these checked by a qualified technician. This problem should be addressed immediately as it can cause severe wiring problems in the whole establishment, and worst, fire.
Refrigerant
Make it habit to check refrigerant levels. Check for any leaks in the refrigerant, as a low refrigerant pressure automatically turns the low-pressure safety on to stop the air con operation. To tell if the refrigerant levels are low, check the larger copper line that goes into the condenser. When you have sufficient refrigerant levels, this line should feel cold and should sweat. If you need to refill, make sure that the material to be used is genuine to ensure maximum compatibility with your unit.
