Common Reasons Your Air Conditioner Is Not Turning On

Electricity Issues

It’s common for AC units to experience power issues from time to time. Usually, you’re looking at tripped circuit breakers or blown fuses. This can happen during the summer when your air conditioner has to work extra hard to keep your home cold. 

These issues can also stem from a power outage. Circuit breakers are designed to turn off when there’s an overload of power, in order to protect your home from fire. If this has happened, you just need to flip the breaker back on. Breakers can be found in two places: the electrical panel and the disconnect box. If you think you may have a blown fuse, you can use a multimeter to run a continuity test. But it’s important to remember to not attempt to replace the fuses with the power on. It’s a pretty dangerous job, so if you don’t have experience in this area, call our well-trained team here at Top Notch Heating & Air today. 

One last area that could affect air conditioner repair is the wiring throughout your home. If you’ve got issues with the overall wiring, you may be hearing strange noises, seeing lights flicker, and/or having appliances malfunction. If this is the case, you’ll need an electrician.

Thermostat

Thermostats are another common culprit behind a malfunctioning AC unit. A lot of the time, it may be that your batteries have run out of juice! Ensure that the thermostat is set to cool and then move the temperature at least 5 degrees below the current temperature. If this still doesn’t work, your thermostat may need to be replaced for your AC to be restored.

Dirty Air Filter

Because your air filters are in use every day, they collect a lot of dirt and dust. If you don’t regularly clean them, they can easily become clogged. This can cause the water that forms from the humidity in your home to freeze in the AC unit. With the coils covered in ice, the unit won’t turn on. Top Notch Heating & Air conducts home air conditioner repair so we can clean out your air filters; they’ll be good as new!

Clogged AC Parts

Over time, it’s common for your AC unit parts to become dirty, as they’re covered by dirt and debris. This can build up on the evaporator coils, condenser, and condenser lines. You can attempt to clean your AC unit yourself, but you need to turn off the power source. Condenser lines can be cleaned with a wet or dry vacuum. If you want your HVAC system cleaned thoroughly, contact us here at Top Notch!

Refrigerant Leak

This type of leak can halt AC operation and also be dangerous, as it can lead to refrigerant poisoning. Don’t attempt to handle this yourself; it needs to be taken care of by an HVAC technician. If you ever notice anything leaking from your AC unit, you need to call an experienced team in, as AC repair needs to happen right away.

Faulty Motor

An indicator of a faulty motor can be hearing strange noises coming from your AC unit. You can test your motor by doing a capacitor test. If you do have a faulty motor, you’ll need to decide whether it’s worth it to fix the motor or just replace it. Our team here at Top Notch can come to inspect your motor and advise you on the best plan of action for AC repair. 

Reset AC Unit

The last thing we can suggest doing is resetting your AC unit. If you don’t have a reset switch, use the thermostat to turn the AC off and wait 5 minutes before turning it back on. You should also check that your shut-off switch is flipped to on. You can also check your inside power switch; it’s usually located near the furnace. When it’s off, it shuts down the blower, which can turn off your AC. Sometimes these switches get turned off by accident, and it’s an easy fix to flip them back on.
