1. Your Cooling System Is Leaking Refrigerant

If there is a refrigerant leak in the refrigeration system, no cooling will take place. While your air conditioner may blow air, it will not cool your home in any way. After all, air will only be sucked into the unit and get filtered before being blown back to the room without any cooling. If you have a refrigerant leak in the evaporator coils, condenser coils, compressor pump or any other section of the refrigeration system, be sure to have it fixed promptly. After the air conditioner repairs, the unit can be recharged to restore the AC to the desired operating condition.

2. You Have Clogged HVAC Air Filters

Over time, these impurities or particles can block the tiny holes in the air filter. This blockage will make it difficult for the blower in the unit to pump cooled air across the filters. As a result, the AC will not be able to blow cold air to the room. Filter replacement, or filter cleaning, can help resolve this problem. Ideally, air filters should be cleaned regularly by a qualified HVAC professional. When they get damaged, they should be replaced promptly.

3. You’re Dealing With A Faulty Thermostat

If the thermostat in your AC unit is faulty, it may not be able to turn on the air conditioner when the temperature rises. If the AC is off, your home will not be cooled. Similarly, if the thermostat is off-calibration, or you have set it to the wrong temperature, the AC may not blow cold air. If you are not getting any cold air from your AC, and you suspect the thermostat is the problem, you should call a competent HVAC contractor to recalibrate the unit, fix it, or replace the unit.

4. Your AC Has Dirty Evaporator Coils

The evaporator coils are located in the air handling unit of your air conditioner. Air is usually cooled when it passes over these coils. The refrigerant in these coils usually absorbs all the heat from the air, thereby reducing its temperature. If the evaporator coils are dirty, heat will not be efficiently absorbed by the expanding refrigerant due to the thick coating of dust on the coils. Similar, if the condenser coils are coated with dust, the condenser unit outside your home will not be able to dump heat outdoors. To resolve this problem, be sure to hire a competent HVAC contractor to service your cooling unit. After cleaning the coils and replacing the filters, you can expect your air conditioner to function optimally.

5. Do You Have A Tripped Circuit Breaker?

If your AC is not blowing air, and you have checked the thermostat, then it is possible that a tripped circuit breaker is your problem. Resetting the breaker will resolve this problem. If it does not, be sure to call your HVAC provider to come and troubleshoot your air conditioner.



If your AC unit frequently develops issues and you have been using it for nearly, or over, a decade, you should consider replacing it. Old units are inefficient and break down often. Therefore, you should replace them as soon as possible.
