If your AC is working, you probably use it a lot especially in the summer because it is necessary and you need to feel comfortable.

When your AC refuses to work at the office, you, your staff, and even customers will feel uncomfortable.

During these times, the issue is difficult to diagnose and it generally requires the help of HVAC repair services to restore the AC system.

However, if your AC breaks down, you might be able to diagnose the problem right away if you are aware of the reasons why it will not turn on. But it can also be a huge problem that requires a technician to come and repair your AC unit.

Read on to learn more.

Thermostat

Your thermostat communicates with your air conditioner. Therefore, in case the thermostat refuses to work properly, the AC has no way to know that it should turn on.

You should first look at what the screen says. In case your thermostat is off or it is showing a blank display, you should try switching it on.

If the thermostat still refuses to switch on, it can be a sign that the thermostat needs to be replaced. You are going to need a professional technician to come and check it out because there might be an electrical problem with the thermostat.

Air Filter

Your air filter should be changed every 30 to 60 days at least. They should be changed more often based on how many pets and people are living with you, and the local air pollution levels that are near your residence. A dirty air filter impacts airflow, which causes your air conditioner to freeze and then turn on.

If your air filter is looking dirty and you cannot recall when you changed it the last time, you should install a new one. if the AC is frozen, it should thaw first after changing the air filter and switching it back on.

The Fuse Blew

Actually, there is a possibility that you blew two fuses: the literal fuse is connected to your thermostat, and in case you are angry that your AC is not working, it could be the internal “fuse.”

A blown fuse between the AC and your thermostat is like a bad battery inside your car. You would need to have it replaced before the machinery is able to do its thing. Unless you have had special training, this is not a fix to try yourself. You should contact a heating and air company to address the problem.

The Circuit Breaker Tripped

One common problem is that the circuit breaker is switching off. Sometimes, when you use too many appliances simultaneously, a circuit breaker trips. It can also happen when there are power surges after the storm.

You should look for the electric panel and then check the switch. If the position is “OFF”, you should turn it “ON.”

If the circuit keeps on tripping multiple times, you should not try to switch it on again. For whatever reason, the circuit overloads, and switching it on can cause an electrical fire. You should contact an electrician immediately instead.

The Transformer is Blown

It is the same case as the blown fuse because the outcome is the same. Your AC will not work until you replace the transformer.

You can also have a bad contractor in the unit outdoors. That is what normally causes a blown transformer, so you need to switch that out too. Wiring issues can also cause it.
