Four Basic AC Troubleshooting Tips

When your AC stops working all of a sudden, the cause could be anything, from a blown fuse to a tripped circuit breaker.

While most issues with your AC would warrant a professional technician’s attention, there are instances when a homeowner could remedy basic issues with some minor troubleshooting.

The following guide on AC troubleshooting shall help you tackle the four most common issues you could have with your AC.

Kindly note a lot of the most common issues with air conditioners could be a direct outcome of improper maintenance. To make sure issues do not arise in the future, we recommend you sign up for a yearly maintenance program for your HVAC system if you’d like to know about the maintenance services or programs that we offer at Red Carpet Air, kindly contact us now or visit our website.

1. Your AC Doesn’t Turn On

If your air conditioning system is not turning on, first inspect your external unit to ascertain whether the condenser is functioning. Ensure the unit is properly plugged and the thermostat settings are right.

Lower the thermostat by five to 10 degrees to check if that addresses the issue – and ensure your thermostat is in the cool setting. John, our maintenance manager, points out that thermostats can be a bit tricky usually and homeowners should read the manual that came in the box to save themselves valuable money and time.

Then find out whether a tripped circuit or blown fuse is the problem.

If your AC’s coil is frozen or it still won’t turn on, there could be an issue with its compressor or motor, and you must contact an HVAC professional to get the system repaired.

2. Your AC is Not Giving Out Cool Air

If your AC has no problems turning on and the thermostat settings are correct, but the system is still not cooling, it could be a case of a blocked or dirty air condenser. The first thing you should do is check the external unit and clean its exterior and surroundings and eliminate weeds or debris that could be blocking air circulation.

Next, make sure the filter is clean. Several times, when the filter is dirty, and it mitigates airflow to the coil, coil freezing issues can arise. If your AC is on for most of the day or you have pets in the house, your AC filter would require changing a lot more frequently. If you cannot see through the filter, it means it needs cleaning or replacement.

If your AC is still having trouble cooling air, there could be issues with your refrigerant or compressor, and you may have to call a professional for help.

3. Your AC Isn’t Cooling Your House Adequately

If your AC is turned on and is on the right settings, but the cooling is still not up to the mark, your AC unit may not be the right size for your house.

Remember, your system must always be adequately sized to ensure your house stays cool during summer. On average, the AC must not have trouble maintaining an indoor temperature that is at least 20 or 25 degrees lesser than what’s outside. Your air conditioner, in other words, is not made to maintain a 65-degree temperature inside when the temperature outside is 95 degrees.

If it’s a regular summer day and the AC is still having trouble keeping up, there could be an issue with the frozen evaporator coil or charge. If there is icing on the external unit, turn off the AC and call in an expert.
