This is the most obvious sign of an AC problem in your home. If you’re getting warm air blowing from your vents instead of cool air which is supposed to come out, there could be several issues, including low refrigerant levels, a malfunctioning compressor, or a clogged air filter.

Sometimes there is not much air coming out and cooling your room. Reduced airflow from your vents might indicate a dirty air filter, a clogged duct system, or a malfunctioning blower motor. While replacing a dirty air filter is something that you can do on your own, it is best to get professional attention.

Your AC unit should cycle on and off smoothly and if it doesn’t, it is the indication of a severe problem. If it’s turning on and off frequently, it might be struggling to reach the desired temperature due to a variety of problems, such as a refrigerant leak or a malfunctioning thermostat.

Your cooling system should be noiseless. Although air conditioners produce some kind of noise, but if you hear strange sounds like grinding, squealing, or rattling, it could signal a serious problem, such as a worn-out fan belt, a loose component, or a failing compressor.

If your energy bills have spiked without a change in your usage patterns, it’s possible your AC is working harder than it should and taking a greater load on itself. This could be due to a variety of issues, including a refrigerant leak, a dirty air filter, or a malfunctioning compressor.

Puddles of water around your indoor or outdoor AC unit are not normal. It could indicate a clogged drain line, a refrigerant leak, or a more serious problem with the unit.

Unpleasant odors coming from your AC unit can be a sign of mold, mildew, or electrical problems. It’s essential to address these issues promptly to protect your health and the longevity of your system.

Air conditioners typically have a lifespan of a decade and a half. If your unit is nearing the end of its expected life, it might be more prone to breakdowns and less energy efficient. Consider replacing it with a newer, more efficient model.
