Air Conditioner Problems That Homeowners Face & Their Solutions     

90% of United States homes use some sort of air conditioning. As summer heat waves roll in, your air conditioner becomes an essential part of maintaining a comfortable and relaxed home environment. However, like any other household appliance, air conditioners are prone to problems.

This blog will explore some common air conditioner issues homeowners face and answer the much-asked question of how to fix an Air Conditioner.

Air Conditioner Problems

Air Conditioner Problems That Homeowners Face & Their Solutions 1

The following are the problems related to the air conditioner:

1.    Dirty AC Filters and Coils

One of the most common problems with air conditioners is dirty filters and coils. Over time, the filters and coils collect dust and particles, which can curb airflow and reduce the efficiency of your system. Dirty filters can compel the air conditioner to work even more, consume more energy, and even lead to overheating.


Regularly clean or replace the air filters. This simple maintenance task can improve airflow, increase efficacy, and extend the lifespan of your AC unit. For the coils, it’s advisable to have a professional clean them annually to ensure they remain free from buildup.

2.    Unusual Noises

Air conditioners are designed to operate quietly. Hearing weird sounds such as grinding, squealing, or banging is a sign that something is wrong. These noises could be caused by a loose part, a motor issue, or something obstructing the fan.


Turn off your air conditioner immediately to prevent excessive damage, and inspect the unit for any visible issues. If you can’t identify the problem, call a professional technician to diagnose and fix it.

3.    The Refrigerant is Leaking

Another reason your air conditioning is not working is refrigerant leakage. Refrigerant is the substance that cools the air in your AC unit. If there’s a leak, your air conditioner won’t be able to cool your home effectively. Refrigerant leaks are highly hazardous, as they are poisonous and can harm the environment, so they should be addressed immediately.


If you doubt a refrigerant leakage, contact an expert technician. They will identify and repair the leak and recharge your system with the correct amount of refrigerant.

4.    The Exterior Fan is Not Working

The exterior fan is necessary for expelling heat from your home to the outside. If it stops functioning, the AC will not be able to chill your home efficiently. This can overheat the compressor, which can cause significant damage to the unit.


Check if there is any debris obstructing the fan and remove it. If the fan still doesn’t work, the motor may be faulty, and you should call a professional to inspect and repair it.

5.    The Compressor Won’t Turn On

The compressor is the heart of your air conditioning system and is responsible for circulating refrigerant throughout the unit. If it doesn’t turn on, your air conditioner can’t cool your home. Compressor problems can be generated by electrical problems, a faulty start capacitor, or a lack of refrigerant.


Check your panel board for tripped breakers and reset them if necessary. If the problem persists, it’s best to consult an expert to solve it, as dealing with electrical parts can be hazardous.

6.    Thermostat Sensor Issues

The thermostat sensor measures the air temperature entering the evaporative coil. If the sensor is out of place, it can force the air conditioner to cycle constantly or behave erratically, resulting in your air conditioning not working properly.


Ensure the thermostat sensor is positioned correctly near the evaporative coil but not touching it. Adjust its position if necessary. If you’re unsure how to do this, consult your air conditioner’s manual or contact a professional.

7.    AC Unit Repeatedly Turns On and Off

Suppose your air conditioner frequently turns on and off. In that case, it may be due to a malfunctioning thermostat, an oversized unit, or a clogged filter. These constant cycles can be stressful on the system and can lead to raised energy bills.


Check and replace your air filter if it’s dirty. Check that the thermostat is working fine and isn’t placed in a location that causes false readings, such as near direct sunlight. If the issue persists, consult with a professional to evaluate whether your system is appropriately sized for your home.

Here are a few practical reasons and solutions to keep your air conditioner in best working condition:

1.    Regular Maintenance:

Routine maintenance can prevent many common issues. Schedule annual check-ups with an expert HVAC consultant to inspect, clean, and service your air conditioning system. This will help target potential issues before they become significant problems.

2.    Timely Filter Replacement:

Dirty filters can cause Many Air Conditioner problems. Depending on usage and the type of filter, replace your air filters every 1-3 months. Clean filters improve airflow, enhance efficiency, and reduce the strain on your system.

3.    Inspect Ductwork:

Ensure that your home’s ductwork is sealed and insulated correctly. Leaky ducts can cause cooled air to escape, driving your air conditioner to work harder to maintain the desired temperature. Sealing and insulating ducts can improve efficacy and comfort.

4.    Monitor Thermostat Settings:

Use a programmable thermostat to manage your home’s temperature efficiently. Set it to higher temperatures when you’re not home and lower when you’re back. This can alleviate the workload on your air conditioner and save on energy costs.

5.    Clear Surrounding Area:

Keep the area around your outdoor unit clear of debris, plants, and other obstructions. Ensure there is at least two feet of clearance on all sides to allow proper airflow and prevent overheating.
