Why Is My AC Blowing Hot Air?

If your AC unit blowing warm air instead of cool air, there could be several reasons for this issue. Let me share 2 common causes for the same.

Why is My Air Conditioner Blowing Hot Air?

The 2 common reason of why AC is giving hot air are as follows;

Clogged Condensate Line:

A lot of moisture is created during the heating and cooling process of your air conditioning device. This moisture is transported outside by the condensate line, usually out of an external wall of your house. 

It is because the atmosphere around the drain line is so moist all the time, accumulations like mould or even algae are common. Warm air fills your house when the AC system's capacity to extract humid air is hindered by a clogged line.

Duct Leaks:

If there's a significant enough leak in your home's ductwork, warm air could be coming from your vents. Cool air is distributed throughout your house by the ducts; but, in the event of a leak, heated air may inadvertently mix with the already-cooled air, resulting in warmer-than-usual air coming out of your vents. 

It is always best to have a professional tackle ductwork concerns. You may avoid many of these issues by having your ductwork cleaned or serviced every three to five years.

They can accurately identify the problem and provide the necessary repairs to restore proper cooling functionality.

You will require a top-notch air conditioner to keep your house cool and pleasant while combating the summer heat!  If you are pondering, “Why is my AC blowing hot air in my house?” I’d like to say that there could be a few different reasons that your air conditioner is blowing warm air instead of cool air. You can resolve a few of them on your own.

• Low Refrigerant:

Low refrigerant is one of the most common reasons for air conditioners generating heated air. To keep your machine operating at its peak efficiency, a refrigerant is required. It is the fluid that takes heat and moisture out of the air. If your air conditioner isn't cooling, it can be because the refrigerant is leaking and there isn't enough of it left to efficiently chill your home. Unfortunately, the problem cannot be solved by just replacing the refrigerant. Call your technician as soon as you suspect a leak.

• Thermostat Problems:

If the air blowing out of your home's air conditioner is warm, there could be a problem with the thermostat. This occurs when outdated dial-type devices are calibrated incorrectly. Verify the settings on your thermostat if you still have access to the air conditioner's manual. Your thermostat might need to be replaced or recalibrated if the issue continues.

To check if the settings on your thermostat are incorrect, you can perform some troubleshooting. Both split and window AC can be used with this. Instead of "on," change the settings to "auto." The fan will only operate in this manner if the air is being cooled. Moreover, double-check to see if the thermostat wasn't accidentally set to the heating setting. It's a common mistake that is frequently overlooked.

• Dirty Air Filters:

Many issues with your device can be brought on by clogged air filters. Even your thermostat's operation might well be affected. Warm and cool air cannot move through the ducts if the filter is dust-clogged. This causes the evaporator coils to freeze, which causes your home's air conditioner to blow warm air. This is why changing your air conditioner's filters on a regular basis is a crucial component of maintenance.

• Dirty Condenser Coils:

The condenser coils in your air conditioner are in charge of extracting heat from the air and releasing it outside of your home. They constantly come into contact with the weather because they are an outdoor item, and as a result, dirt and grime build up on the coils over time. Heat transfer is impeded by this. When warm air from your air conditioner fills the house, you will start to notice this. The device as a whole is put under unnecessary strain by the filthy coils, which increases wear and tear.

• Fan Problems:

Your air conditioner's fans might not be functioning properly for a number of reasons. It might be a result of a broken motor, worn belts, or inadequate lubrication. The fans may experience issues as a result of dirt and debris. Poor airflow will result if the fan malfunctions, whether it's on the indoor or outdoor unit. This causes your air conditioner to start blowing warm air instead of the expected cool ones. If left unattended, fan issues could lead to compressor failure.

I’d like to conclude here as I believe this suffices your query about “Why is my AC blowing hot air in my house?” I hope this helps :)
