Air Conditioner Not Blowing Cold Air That Is Running How To Fix It

Air Conditioner Not Blowing Cold Air Your house is heating up, and the air conditioner is on but not blowing cold air. What should you do if your central air conditioning system fails? If you’re not sure why your air conditioner isn’t delivering cold air, consider the following possibilities. The air conditioner will stop pumping cold air if the thermostat is set incorrectly. Another cause could be that the air filter needs to be replaced, or that debris or dust is obstructing air passage on the coils.

To function and chill efficiently, air conditioning systems rely on a variety of components. An inside air handler unit (a furnace or fan coil), an evaporator coil, and copper tubing that connects the indoor and outdoor units are all components of a standard air conditioner. “Why is the air conditioner not cooling?” is a question with numerous answers. We’ll explain why your air conditioner isn’t blowing cold and offer the finest options.

What Causes An Air Conditioner To Cease Blowing Cold Air?

Filter Is Clogged.

• Whether your air conditioner isn’t blowing cold air, check to see if the air filter needs to be cleaned or replaced. If the air filter in your air conditioner is dusty, replace it to allow more air to pass through. If your air conditioner’s air filter is blocked, it won’t be able to pull enough air through it to keep the unit cool.

Thermostat Is Set Incorrectly.

• Your air conditioner’s thermostat can be set to HEAT or FAN ONLY. Check that it’s set to COLD or COOL. You may have also set your home thermostat to a temperature that is greater than the ambient temperature. This will prevent the air conditioner from blowing chilly air or even turning on. Make sure the thermostat is properly programmed and set.

Coils That Are Dirty Or Obstructed

• If your air conditioner is on but you’re not experiencing frigid temps inside, a clogged condenser coil could be the problem. The lack of cold air flowing from your air conditioner could be due to dust, grime, or something else clogging the coils. To function effectively, these coils must be clean. Clean the coils of any dust or grime, since a buildup of debris or a blockage will impair the performance of your air conditioner and cause it to stop blowing cool air.

The Circuit Breaker For The Air Conditioner Tripped.

• An overflow of power utilisation may have tripped a circuit breaker. Make sure the electrical power to the air conditioner is turned on by checking the AC breaker in the breaker box. If the breaker has been tripped, reset it and inspect the air conditioner. A transient overload may have occurred, and resetting the breaker can resolve the issue.

There is no cold air because of a refrigerant leak.

• Refrigerant is a chemical that is used to chill the air in your air conditioning system. The AC may not blow cold air if there is a refrigerant leak. Your air conditioning system may operate for an extended amount of time without cooling your home, which is a sign that a leak has occurred. Leaking refrigerant might potentially harm the compressor, causing the air conditioner to shut down. If you discover a leak, contact a professional.

Problems with the compressor or capacitor

• The AC compressor or another component can be malfunctioning. The capacitor should be checked first if the compressor stops working. The capacitor in the outer condenser unit is the size of a coke can. The compressor will not run if this capacitor is defective. If the capacitor is faulty, use a metre to check it and remove and replace it. If the capacitor is in good working order, the compressor must be examined.

Air conditioner Unit Is Undersized

• All air conditioners are classified according to the quantity of cooling they can provide. BTUs is the name of this label (British Thermal Units). If the outside temperature is mild, the air conditioner may work fine. When the temperature outside climbs, though, your air conditioner may not be able to keep up. This could indicate that your air conditioner is undersized for the amount of room you’re cooling. Check your air conditioner’s BTUs and compare them to the size of your home. It’s possible that your air conditioner isn’t producing enough BTUs to keep your home cool. If this is the case, a larger BTU AC unit should be considered.

When Your Air Conditioner Is Blowing Hot Air, How Do You Check It?

No Cooling From The Window Air Conditioner

8. If you have a window air conditioner in your home, check sure it is correctly fitted and that air can circulate around it in order to efficiently cool a room. If the window air conditioner isn’t put correctly, it won’t cool as efficiently as it should. Make sure the window AC’s seal isn’t letting any hot air in from the outside. Make sure nothing is blocking the airflow from the window air conditioner.

If you have an older air conditioner with a faulty compressor or can’t figure out why the air conditioner isn’t blowing cold, it may require professional servicing. There are a slew of additional reasons why your air conditioner isn’t blowing chilly air. Some are quite complicated, so if the previous information did not solve your problem, we recommend contacting a professional HVAC service firm for a quote.

When troubleshooting, turn off the air conditioner. A competent HVAC – Heating Ventilation Air Conditioning – expert should always do some AC repairs. If you know what you’re doing, replacing a defective compressor capacitor is a simple task. It’s advisable to get a professional to come take a look and give you a price if you know you have an air conditioner compressor problem.
