Frequent Air Conditioning Problems and How to Fix Them

The NATE-certified technicians from Deljo Heating & Cooling provide the very best in air conditioner repair in Roscoe Village and surrounding areas, and our services also include AC maintenance, replacement and 24/7 emergency service.

Today’s AC units are ruggedly constructed and will last anywhere from 10 to 15 years or more. Still, problems inevitably develop, and here are some of the more common AC problems you’re like to face.

The unit isn’t running.

The problem could be a breaker or fuse used to prevent the unit’s motor or compressor from overheating. If this occurs, let the unit cool for about five minutes before resetting any breakers.

The unit is running but not releasing cool air.

Both the thermostat and the outdoor unit need to be checked as it’s possible there’s an electrical disconnect between the two.

The AC unit shuts on and off repeatedly.

This problem is called “short-cycling” and usually indicates a problem with the condenser unit or the evaporator.

Refrigerant is low.

Refrigerant is the chemical that cools the air in your system. If the refrigerant level is low that could well indicate a leak, and you need a qualified Deljo technician to find and fix the problem.

Compressor isn’t working.

The compressor applies energy to the refrigerant and propels it though the coils of the unit to carry out heat exchange. If there’s not enough refrigerant, the compressor will run hot and eventually seize up. If there’s too much, the refrigerant will return to the compressor, potentially causing it to fail.

Drainage isn’t working.

Like your filter, the unit’s drain line can become clogged, causing the drain pan to fill and overflow, damaging whatever is around it.

Condenser coils are dirty.

These are located outside with the compressor and can easily become dirty. Washing with a water hose usually suffices, but if they’re too dirty they should be professionally cleaned with a chemical cleaner.

The best way to prevent common AC problems like these is through a preventive maintenance program performed by Deljo’s NATE-certified technicians.

Ari Telisman Chicago IL.

My hot water heater had some leaky pipes due to corroded unions. The repair took longer than I thought due to some unforeseen circumstances. Unfortunately after the repairs the water heater stopped working...
