How do you fix an air conditioner that is not cooling?

Have you ever entered a room expecting a blast of cool air and then found an uncomfortable wave of heat? When your air conditioner quits suddenly, particularly in the summer months when you depend on it to keep comfortable, an air conditioner (AC) that isn’t cooling can be rather frustrating. But before you worry about expensive fixes or replacements, you should know that a lot of AC cooling problems can be fixed with a few easy checks. Fortunately, a little troubleshooting will help many problems that lead to malfunction of ACs. This guide will bring you through several techniques to resolve an air conditioner not cooling as expected. By the end of this piece, you will have a thorough knowledge of how to identify the issue most of the time and to fix it yourself.

Check the Thermostat Settings

Examining the thermostat settings comes first when your air conditioner isn’t cooling. The system may be put in “fan” or “heat” mode instead of “cooling,” which would keep the AC from chilling your room.

Steps to troubleshoot:

• If the thermostat is on “fan,” “auto,” set it to “cooling.”
• Make sure the temperature is lower than the current room temperature.
• Make sure the fan is set to “auto” so it runs just during active cooling of the system.
• If the thermostat runs on batteries, changing them could also help to address the issue. Continue to the next step if cooling is still not happening.

Look over and clean the air filter

One of the most often occurring causes of an air conditioner’s stopping of cooling is a filthy or blocked air filter. The performance of the system suffers when the filter is full of dust and trash since reduced airflow results. This reduces cooling capacity as well as might cause the evaporator coil to freeze.

How to clean the air filter:

• Cut the air conditioner off.
• Usually found either inside the AC unit itself or in the return air duct, find the air filter.
• Take off the filter and look for dirt. If it is reusable, either vacuum the trash or clean it with water and mild soap. If the filter is a disposable one, replace it with a fresh one.
• Turn on the system once the filter has been properly installed.
• Depending on use and environmental elements like dust or pet fur, air filters should ideally be cleaned or replaced every one to three months.

Check the Circuit Breaker and Electrical Panel

If your air conditioner is totally unresponsive, the problem could be electrical. Tripping an overloaded circuit breaker will cut off the air conditioner’s electricity and cause it to completely fail.

Steps to check the circuit breaker:

• Locate your home’s electrical control panel, often found in the basement, garage, or utility room.
• See if the breaker switch linked to the air conditioner trips. If so, turn off the switch and then turn it back on once more.
• If the AC still fails or the breaker trips once more soon after, there may be a more major electrical problem needing professional air conditioning repair and maintenance services to check the system.

Inspect the Condenser Unit

Another source of cooling issues in the air conditioning system is the condenser unit—its outside component. Leaves, mud, and grass clippings, among other trash, can gather around the unit and block airflow, so impairing its heat expulsion capacity.

How to clean the condenser unit:

• Through the electrical panel, cut off the air conditioner’s electricity.
• Using a broom or leaf blower, clear any trash from all around the condenser.
• For debris or damage, check the fins—thin metal strips on the side of the condenser. Dust the fins with a gentle brush.
• Unscrew the condenser unit top and carefully hose down the fins and coils for a deeper clean. Be careful not to twist the fins.
• Frequent condenser unit repair can ensure that your AC runs without problems and avoid future cooling problems.

Check over the refrigerant levels

Low refrigerant levels could seriously affect the cooling capacity of your air conditioner. Refrigerant is a component used in the cooling process; so, an AC will not be able to efficiently cool the air should there be a leak or if the levels are too low. Low refrigerant shows itself as warm air blowing from the vents and ice on the evaporator coils.

Steps to troubleshoot:

• If you suspect a refrigerant leak, you’ll need to contact a licensed HVAC technician. Handling refrigerant requires specialized tools and is regulated by law.
• The expert will mend any leaks and check the refrigerant levels. They will recharge the system with the right refrigerant once the leak is repaired.

Note: Unlike fuel, refrigerant does not run out; if levels are low, a leak most certainly needs to be fixed.

Maintain Correct Airflow All Around the System

Sometimes the problem is with your house’s airflow rather than the air conditioner itself. Proper circulation of cool air might be hampered by blocked or closed vents, kinked ducts, or even poorly planned ducting.

Steps to improve airflow:

• Make sure every room’s vents are open and free from furniture or drapes.
• Especially in flexible ducts, look for any obvious damage or bends in the ducting.
• If you find inconsistent cooling in several rooms, think about adding a zoning system or balancing dampers in the ductwork to direct airflow where it’s most required.

Check for a Frozen Evaporator Coil

An often occurring cause of an air conditioner failing to chill is a frozen evaporator coil. The system cannot efficiently absorb heat when the coil gets too cold, hence, ice accumulates on it and poor cooling performance results.

How to fix a frozen evaporator coil:

• immediately turn off the air conditioner so the coil may defrost. One could take several hours.
• After the coil has defrosted, clean or replace the air filter, as a dirty filter is a common cause of freezing.
• Verify that the thermostat is adjusted properly and that the fan is working to encourage coil ventilation.
• If the evaporator coil keeps freezing, refrigerant problems or airflow concerns could be the cause; both will call for expert care.

Check the compressor

The heart of your air conditioning system is the compressor, so the improper operation of it will not cool your air. A defective compressor can prevent the AC from turning on completely or cause the system to short-cycle—turn on and off often.

Steps to troubleshoot the compressor:

• if you hear odd noises coming from the exterior unit, it Indicates a compressor problem. It could be clicking, rattling, or humming sounds.
• Check the capacitor—a gadget designed to make the compressor start—if you find the compressor not starting. Many times, a technician can repair a defective capacitor without having to replace the complete compressor.
• If the compressor fails, you most likely require an expert to evaluate whether replacement or repair is best.

Contact a Professional HVAC Technician

If none of the above troubleshooting steps resolve the issue or if you feel uneasy about handling these tasks, it is advisable to call a qualified HVAC specialist such as BestAirServices. We can examine closely, identify the problem, and do the required repairs. As licensed technicians, we can:

• Examine closely the parts of your air conditioner.
• Look for refrigerant leaks and then recharge the system.
• Replace or fix malfunctioning electrical parts.
• Make sure that the system is running properly and successfully chilling your house or commercial space.

Conclusion

Your air conditioner might not be cooling for a number of reasons, ranging from simple issues like an incorrectly set setting to more serious issues like a compressor failing or refrigerant leaking. These troubleshooting techniques will help you maybe fix the problem on your own. For more major issues, though, it’s always advisable to call a qualified HVAC specialist like BestAirServices.
