The Top 6 Reasons Why Your AC Isn’t Blowing Cool Air

AC Isn’t Blowing Cool Air

Is your AC Isn’t Blowing Cool Air? For homeowners, this can be very unpleasant and stressful. It’s not ideal when your air conditioner fails, but it does happen. Knowing how your air conditioner operates may help you better understand what might be causing it to malfunction. But, if you are not sure about its functioning, we suggest calling an AC repair service provider instead of trying to figure it out on your own.

How Does an Air Conditioner Work?

A liquid refrigerant is used in your air conditioner. This liquid absorbs heat from your home by passing over the interior evaporator coils. This liquid becomes an ice gas after absorbing the heat. The fan of the air conditioner blows over the refrigerant-cooled coils, forcing cold air through the ductwork and into the house.

The heat is then carried back to the outside condensing unit by the refrigerant in gas form, which then turns into a liquid after releasing the heat into the external air. This cycle is repeated indefinitely to keep your home cool.

Why Isn’t Your AC Blowing Cool Air?

Why Isn’t Your AC Blowing Cool Air

A lot of things can cause your AC to stop blowing cold air as there are a lot of processes and components that are used in its functioning. There are various things you need to consider when there are so many processes involved. We’ve come up with some possible reasons that might help you understand why your AC stopped blowing cool air suddenly.

The Thermostat May Be Set Incorrectly 

If your house is getting a little hotter than usual, first check the thermostat settings. Make sure the thermostat is set to an appropriate level. If the thermostat is set to cool, double-check that the temperature setting hasn’t been changed.

The Thermostat May Be Set Incorrectly

If it’s switched off, set to heat, or set for the continuous fan, switch it back to cooling mode. Check for chilly air flowing from the registers a few minutes after the machine has powered on.

There’s no need to be concerned if it’s freezing outside! If not, move on to the next stage in the troubleshooting procedure, which is to examine the air filter.

Filthy Filter

An air filter may be located in or near the interior air handler component of your air conditioner. The filter catches dirt, pollen, and other airborne particles as they enter the air handler equipment. It cleans and improves the functionality of the system’s components, as well as the air in your house. Airflow will be obstructed by a clogged air filter, causing your home to overheat. In extreme situations, it may cause the system to shut down completely.

Filthy Filter

Look for your system’s air filter, switch it off, uninstall it, and test it if your thermostat is operating properly but you still don’t get cold air. If your central air conditioner is still not cooling your house after you’ve made sure your air filter is clean, go for an AC repair service as soon as possible.  

The Condenser May Be Partially Blocked

The condenser unit’s exterior contains a large outside coil that wraps around the unit for the bulk of its length. The coil is made up of a series of extremely tightly spaced thin metal “fins.” Your air conditioner may be functioning but not lowering temperatures inside due to a blocked or jammed condenser coil. While it’s operating properly, the condenser fan pushes air into the outside device through the condenser coil to harvest heat energy from your house by gathering dirt, grass, and other airborne particles that block the coil.

A Malfunctioning Heat Pump

A heat pump looks similar to an air conditioner, but it has extra components that allow it to cool and heat your home. In terms of ventilation, it’s identical to an air conditioner’s condenser device, and it’s prone to the same issues: dirty, clogged coils, frozen coils, refrigerant leaks, compressor failures, and so on. If your heat pump system isn’t cooling, check the thermostat settings, air filter, and condenser unit for any of the previously identified issues.

Frozen Evaporator Coil 

The interior section of the central air conditioning system includes an evaporator coil. The evaporator coil is situated outside the furnace in its drawer if your indoor appliance is a refrigerator. If the indoor device is a fan coil, the evaporator coil is housed within the fan coil cabinet (typically as part of a heat pump system). The evaporator coil removes heat energy and humidity from warm indoor air. The air is then blasted back into your home, cooling and relaxing it. 

Symptoms of a frozen evaporator coil include may include the copper refrigerant tube forming frost, inadequate ventilation, increasing energy prices, etc.

Leak In Refrigerant

The chemical refrigerant is required for proper cooling. As it flows through the system’s interior and outdoor coils, it transforms from a liquid to a gaseous state, collecting heat energy and humidity from indoor air and releasing it outdoors.

Depending on the size of the leak, your AC system may cease blowing cold air, function for prolonged periods without adequately cooling your home, or cause a broken or defective compressor and complete system shutdown.

It’s always good to understand how the AC and other electronic equipment are in your housework. It helps you do an initial check and get down to the root of the problem.
