There are no standard steps to “reset” an air conditioner on Long Island when it isn’t blowing cold air. An air conditioner is a complex system, and there are several potential reasons why yours isn’t cooling your home.

If your AC is blowing warm air, rather than a reset, you can follow some simple troubleshooting steps.

Troubleshooting an Air Conditioner Without Cold Air

Follow these essential steps before you talk to an HVAC contractor on Long Island:

1. Check the thermostat (central system) or remote settings (independent mini-split). Ensure the temperature is set between 70°F and 77°F for effective summer cooling.
2. Check the electrical panel. Sometimes after a power outage or surge, the outdoor unit might trip the breaker. You will hear air inside, but the condenser outside won’t be doing any cooling work. If the breaker is off, set it to on and test the system.
3. Check the filters and vents. Filters should be cleaned or changed every three months. If your filters are clogged with dust, the system won’t provide adequate cooling. You can check your owner’s manual to determine if you have washable or replaceable filters. If you use a central system, check that the supply and return vents aren’t obstructed by dust or debris.
4. Check for debris around the outdoor unit. The system won’t run properly if leaves or other organic materials clog the shroud of the outdoor condenser. Remove any debris from the unit and then test the system again.

If you have tried all of these steps and your system still doesn’t blow cold air, there could be another problem, like a refrigerant leak, thermistor failure, compressor failure, or even a severely clogged condensate line. Expert troubleshooting and cleaning are recommended after following the basic steps.
