Why Is My Daikin AC Not Cooling But The Fan Is Working?

It’s a phone call Kotz Heating, Cooling & Plumbing often gets during the hot summer months: A Waterford, MI or Oxford, MI homeowner has just come home after a long day of work, maybe in the hot sun, only to discover their Daikin air conditioner is not keeping the house cool, even though the fan is running. Our HVAC technicians are always ready to help, but before making the call let’s talk about some things you might be able to do on your own.

Power issues

If the AC doesn’t seem to be working at all, always check the electric panels to make sure it’s not a simple case of a tripped breaker. Of course, if the breaker keeps tripping after it is reset you will need to call for professional help. Also remember many air conditioners have built-in overload switches which might need to be reset.

Check Out the Thermostat

Your Daikin air conditioner won’t work if it’s not able to communicate with the thermostat. First make sure the temperature is set correctly. Don’t laugh as mistakes can easily happen, especially with newer more complicated digital and smart thermostats. Some thermostats also have batteries that can die. Replace them just to be safe.

Clogged Filter

Some air conditioners will automatically shut down if they sense the filter is dirty or clogged. Clean or replace the filter and see if that fixes the problem.

Ice Buildup

This usually happens on the evaporator coil inside the air handler and will cause the AC to blow warm air. Freeze ups are usually caused by poor airflow or a low refrigerant level. Once again, the first step is to check for a clogged filter. You can’t restart the air conditioner until the ice melts. Set the thermostat to fan only. Running the AC fan is the quickest way to thaw the ice buildup. If the ice returns after replacing the filter, you will have to call in the pros.

Practice Preventive Maintenance

The best way to prevent a hot weather catastrophe with your Daikin air conditioner is to make sure you are scheduling regular maintenance and tune-ups. This can prevent many of the problems we just talked about. Even then, the time will arrive at your Waterford, MI or Oxford, MI home when it makes sense to replace your old AC with a new, more efficient model, instead of paying for expensive stopgap repairs.
