There can be a few reasons why your AC is kicking the breaker.

Dirty filters. When the AC is being used often, the inside cabin air filter should be cleaned more often. When it become clogged, the unit works harder, draws more amps and will heat up while drawing more power.

While you have the filter removed for cleaning, check the evaporator coils directly above the filter housing. They should be clean and unobstructed. If they are dirty, the same conditions will effect the AC.

The third area to check is the condenser coils on the roof. When the shroud is removed, the coils can be inspected for contamination. You will almost always find these to be dirty.

On some models, the fan motors have serviceable bearings that require periodic maintenance. This is nothing more than a couple drops of oil on each bearing cup on the fan motor, one on each end of the armature. If there are no cups or oiling points, the motors are maintenance free and replaced as a unit when they fail.

The last thing I would check is the voltage supply on the applicable circuit. If it has a low voltage because of a faulty power supply, a bad breaker, poor connection or faulty curb side feed, the unit will over heat and draw much more amperage.

Also remember that whenever the outside temperatures are elevated as they have been this summer, the AC will have to work much harder to maintain the same inside temperatures. An older unit is not as efficient as a new one, and any restrictions to its air flow will effect if more rappidly. Like anything else, proper maintenance is mandatory for the best operation.

Thank you so much! ! ! I have checked and cleaned the inside filters but none of the rest. I will check the rest of the things mentioned.

Thanks again! !
