How to fix the Three most Common AC Problems

When your air conditioner stops working, and the air conditioning is not cooling, it can cause stress. If the AC does not turn on, it might be as simple as a blown fuse or tripped circuit breaker.

Many problems with your air conditioner need a professional technician to repair them. Sometimes, a homeowner can fix simple AC problems with some troubleshooting.

The following troubleshooting guide should help you with these problems. We hope it will help you to address four of the most common issues, if you don’t mind.

1. Your AC Won’t Turn On.

Your first step is quite simple. Lower your thermostat by 5 to 10 degrees. See if that fixes your problem. Check if your thermostat is set to a cool setting. Our Maintenance Manager points out that many thermostats are tricky to set. Homeowners can save themselves time and money by reading the manual.

Check if a fuse is blown or a circuit breaker has tripped. Suppose your air conditioner still will not turn on, or you have an AC frozen coil. You may have a problem with your motor or compressor and need to contact Platinum Air to repair your AC.

2. Your Air Conditioner Is Not Blowing Cold Air.

Next, check your filter. Could you make sure that it is clean? We often find the filter is dirty. The evaporator coil can freeze when the filter restricts airflow to the coil. You may need to change your filter regularly for those with pets or people running the AC at low temperatures. To check the filter, pull it out, and see if you can see thru it.

3. Your Air Conditioning is not Cooling Adequately – Maybe AC has a Frozen Coil.

Suppose your air conditioner is on and set but still not cooling your home adequately. In that case, you may have a unit not sized appropriately for your home.

Remember that your system should be sized to keep your home cool on the average summer day. Your AC should maintain a 20-25 degree temperature difference between outdoors and indoors. In other words, your air conditioner is not designed to keep your home at 68 degrees when it is 95 degrees outside.

Suppose it is a typical summer day, and your air conditioner still can’t keep up. In that case, you may have a problem with the charge or an AC frozen coil. If you see ice on your outdoor unit, shut it off and call a professional.
