Why Is My AC Not Cooling?
Unless your AC is leaking refrigerant, the main reason it’s not cooling is a faulty compressor unit. If you suspect that the compressor is the cause, you’ll need to get a licensed HVAC professional to check the unit. In some cases, the compressor may have failed because it’s old and needs to be replaced.
Ensure refrigerant levels are correct
When the refrigerant in your AC is low, your cooling system will start to struggle to provide enough cooling for your home. Ac Repair Hesperia The good news is that your AC won’t shut off completely until it has the necessary levels. If your AC won’t run because it’s missing the proper amount of refrigerant, it’s likely a leak somewhere in the system. Your technician will check for a leak and try to determine what’s causing the low levels of refrigerant in your AC. If you do discover a leak, adding more refrigerant will only temporarily solve the problem. In the meantime, your AC will cease to blow cold air and will need to be serviced again.
Another common reason for low refrigerant levels is a dirty air filter or dirty coils. A dirty filter will reduce the amount of airflow through your AC, which can lead to ice buildup. If the refrigerant is too low, the temperature will drop below the recommended design temperatures. If the airflow is too low, you may need to clean the filters.
Check ducting
If your air conditioner is not cooling, the problem may be in the ducting. Your ducts carry the cold air from the main blower into each room. If the ducting is blocked, cold air may blow out before it reaches the registers in each room. This can result in mild-warm return air instead of cool air.
You can check your ducts by opening and closing the vents. Most vents are equipped with a toggle or switch for opening and closing the damper. Sometimes, these may be accidentally closed when cleaning the vent or never opened. If you see that the damper is closed, close it immediately and check to see if air is not coming through.
If you find that your ducts aren’t sealing properly, you should contact a heating and air conditioning company. Doing so now can prevent a large problem in the future.
