When your air conditioner stops working, it can cause stress. But it might be something as simple as a blown fuse or tripped circuit breaker.

Many problems with your air conditioner require a professional technician to repair. Sometimes, a homeowner can fix simple AC problems with a bit of troubleshooting.

The following troubleshooting guide should help you with these problems. We hope it enables you to address four of the most common issues you may encounter.

Poor maintenance is the most common problem with air conditioners. Set up an annual maintenance plan for your HVAC systems to avoid future issues. For maintenance program pricing details, please visit https://airconditioningtucson.com. You can also call us at (520) 867-9861.

1. Your AC Won’t Turn On.

Check your unit outside if your air conditioner isn’t blowing cold air and the AC won’t turn on. Find out if your condenser is running. Make sure that the outside unit is plugged in. Also, look at your thermostat to ensure it is set at the right temperature.

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. Homeowners can save themselves time and money by reading the manual.

Then 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 you will need to contact Platinum Air to repair your AC.

2. Your Air Conditioner Is Not Blowing Cold Air.

What if your AC turns on when the thermostat is set correctly, but your system is not cooling? In that case, you may have a dirty or blocked air condenser. For this issue, check the outside unit and clean it. Remove any debris or weeds that may block air circulation.

Next, check your filter. Make sure that it is clean. We often find the filter is dirty. When the filter restricts airflow to the coil, the evaporator coil can freeze. You may need to change your filter often 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.

What if the AC is still not blowing cold air? In that case, you may have a problem with your compressor or refrigerant, and you will need to contact Platinum Air.

3. Your Air Conditioner Isn’t Adequately Cooling Your Home – Maybe AC Frozen Coil.

Suppose your air conditioner is on and set properly but is still not cooling your home to your standards. 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 outdoor 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 icing on your outdoor unit, shut it off and call a professional.
