Several Common AC Problems and How To Fix Them

Homeowners should be aware of many common AC problems and solutions. Maybe you have noticed something is wrong with your AC after waking up drenched in a layer of sweat. If you are in the middle of the summer, you may have already considered contacting the professionals, since the thought of suffering through the summer without any AC is unthinkable. However, some AC issues can be diagnosed and easily fixed if you are just a little mechanically inclined. Read on to find out some of the most common AC issues and how you can fix them.

Common AC Problems

Here are some common AC problems and a quick fix for AC units.

Leaking Refrigerant

The cause of refrigerant leaks is either due to the AC in your home being undercharged at installation or some other issue. A real solution is not just adding refrigerant to the unit. The amount of refrigerant in every AC unit must be precise and match the manufacturer’s specification. A leak is normally the problem and must be handled immediately.

Re-charging may be necessary if your AC unit is located in a commercial establishment. However, you still need to find and fix the leak to repair the issue. Repairing a leak is often best left to a professional, especially if the leak is located in an access port, valve, or evaporator coils.

You can also try a freon leak repair kit if you manage to diagnose the problem on your own, such as a small refrigerant leak.

Blower Motor Won’t Turn On

If your AC won’t start and the blower motor won’t fire up, there could be several issues with your AC unit.

It may be as simple as a tripped breaker. You can simply check the breaker panel. You will find that all AC units have at least two different breakers, once for the condenser and one for the fan. If it is halfway tripped, you can turn it all the way off first before turning it back on.

Additionally, a faulty or damaged wire could also be the cause. If this is the case, hiring a professional is your best bet since they can troubleshoot your thermostat and the other wiring that runs to and from the AC.

Frozen Coil

A Frozen coil is another reason an AC unit fails to blow cold air. The good news is that it can be an issue that doesn’t need the assistance of a professional.

There are many reasons why your AC coil has frozen up, including:

• Low refrigerant
• Broken parts
• The temp outside is too low
• Restricted airflow

You can simply fix this issue by turning off the AC and setting the fan to run on auto to help melt the ice around the coil. You can also check the air filter and evaporator coil for debris and dirt. Make sure you clean it all up. If your AC still freezes, it means you either have low refrigerant or a damaged refrigerant line.
