In the summer, your air conditioner keeps you cool enough to live comfortably. If your AC isn’t running as efficiently as it should be, it might be time for some repairs.
If an HVAC technician comes to fix your AC, there are typically a few repairs that take precedence over others. Below are four common reasons your AC might break.
1. Frozen Air Conditioner Unit
There are a few different things that can cause your air conditioner to stop producing cool air. One of the reasons is that your air conditioner has frozen coils. You may run low on coolant if your air conditioning unit has frozen coils. It’s also a sign that there could be something wrong with how your AC blows out the cool air.
A dirty furnace filter can affect how well your AC blows out cooler air, so you should clean or replace these filters. Another reason your air conditioner may suddenly stop working is that the blower fan has broken and will not be able to push out cool air; instead, all of the cold air will stay inside the AC unit and freeze some internal components such as the coils.
2. Refrigerant Leaks
If your air conditioner is low on refrigerant, this could be a sign that your AC leaks. Leaks can be bad for the environment—if your air conditioner leaks, you should immediately call a professional technician to repair it.
A technician will diagnose the problem, fix the leak, and then check the repair to ensure there is no longer a leak. When they have completed the repairs, they will let your AC system run for some time and check that it charges correctly with the refrigerant specified by the manufacturer.
3. Sensor Problems
Some air conditioners have a sensor built into them to determine the temperature of the air blowing into the evaporator coils. If the sensor can no longer read the temperature, it won’t be able to set the room’s temperature.
If the sensor is not in the correct position, it could keep the AC from cycling on and off. The sensor needs to be within three inches of the evaporator coil, but it should not touch the coil—a technician can easily adjust its position for you.
4. Dodgy Wiring
If your air conditioner has been installed by someone who is not a professional, they may have wired it improperly. If this is the case, you will want to call out an experienced technician to make sure that your air conditioner is safe to use.
They will be able to reinstall your air conditioner, so it’s hazard-free. Improper wiring can also cause a fire, meaning you’re not safe using your air conditioner.
If you’re having problems with your air conditioner, you will want to schedule an inspection as soon as possible to ensure you don’t have a problem affecting your home or your appliances.
