Why Is My AC Blowing Air But Not Cooling?
Does your air conditioner seem to be working, but it’s not cooling your house? A system that’s blowing warm air is a cause of concern, especially in those hot and humid summer days. In this article, we’ll explain why your AC is blowing air but not cooling and what to do about it.
The Problem of an AC Blowing Air but Not Cooling
Why is your AC blowing air but not cooling? A few common problems can be the cause of your system failing to cool your home. The most frequent causes are:
- Low refrigerant levels
- Dirty filters
- Faulty compressor
- Blocked vents and ducts
Low Refrigerant Levels
Low refrigerant levels are one of the main causes of an AC blowing air but not cooling. When your air conditioner is low on refrigerant, it can’t cool your house properly as the air won’t be cooled and/or won’t reach your registers. This is usually caused by a leak somewhere in your system. To fix this issue, you’ll need to find and repair any refrigerant leaks, and then fill the system with the recommended amount of refrigerant.
Dirty Filters
Air filters can cause your AC to become clogged when they haven’t been replaced in a while. This blocks airflow and, as a result, your air conditioner will start blowing air but not cold. To fix this issue, you’ll need to clean or replace your air filters on a regular basis, depending on their installation and manufacturer recommendations.
Faulty Compressor
Compressor problems can also be the cause of an AC blowing air but not cooling. If your compressor isn’t working correctly, the unit will struggle to cool your home to the desired temperature. To fix this, you should have a professional come out and inspect your system, as a faulty compressor may need to be replaced.
Blocked Vents and Ducts
Clogged or blocked vents and ducts can also be a cause of your AC not cooling. If your air conditioning system is blocked, it won’t be able to circulate air properly, thus preventing it from cooling your home efficiently. To fix this issue, you’ll need to have a professional clean and unblock any blocked vents and ducts.
What to Do if Your AC Is Blowing Air but Not Cooling?
If your AC is blowing air but not cooling your home, you’ll need to take some steps to determine and fix the underlying issue. The first and most important step is to have a professional HVAC contractor come out and inspect your system. They’ll be able to analyze and determine the exact cause of your system’s lack of cooling, and then advise you on the best course of action.
If you have a low refrigerant level or compressor problem, you’ll need to have these repaired or replaced by a professional. However, if the cause of your AC blowing warm air is dirty filters, air ducts, or vents, you may be able to take care of this yourself with the help of a few tools.
Conclusion
If your AC is blowing air but not cooling your home, make sure to have a professional HVAC contractor come out and inspect your system. This is important, as various issues can be the cause of an AC blowing air but not cooling. From low refrigerant levels, to a faulty compressor, clogged air filters, or blocked vents and ducts, you’ll need to have these issues identified and repaired in order to get your air conditioner up and running again.

AC Blowing Air but Not Cold: Manufacturer Recommendations and Best Practices
During the hot summer months, homeowners everywhere rely on air conditioners to keep their homes cool and comfortable. Unfortunately, these systems don’t always perform as they should and sometimes they might experience issues such as “AC blowing air but not cold.” To help prevent this issue from occurring now and in the future, it is important to be aware of the manufacturer’s recommendations and the best practices for AC care and maintenance.
Manufacturer Recommendations
The best way to ensure that your air conditioner is able to work efficiently and provide cool air is by following the manufacturers’ recommendations for use, maintenance and service. These recommendations may include:
-
Regularly checking the air filters to ensure they are clean and free from dust, dirt and debris. Dirty filters can interfere with the efficiency of the system and reduce airflow, resulting in warm air being pumped into your home.
-
Maintaining a temperature setting of between 65-75 degrees, as recommended by the manufacturer. Setting it too low or too high can put an unnecessary strain on the system and lead to breakdowns or a decrease in efficiency.
-
Installing a thermostat that is compatible with your system. This will help it to run efficiently and keep your home cool and comfortable.
-
Having your air conditioner serviced by a professional at least twice a year. Regular service will help to prevent build-up of dirt, dust, and debris which can reduce the efficiency of your system and lead to AC blowing air but not cold.
-
Checking for leaky ductwork and sealing them regularly. This is important as leaky ducts can cause warm air to enter the system and make it difficult for the air conditioner to cool the air.
Local Appliance Companies’ Recommendations
Most local appliance companies can provide specific advice on how to take care of and maintain your air conditioner. Some of these recommendations may include:
-
Checking for dirt build-up around the air conditioner’s components and cleaning it on a regular basis.

Checking the unit’s coils to make sure they are clean and free of dirt, dust and debris.
-
Ensuring the area around the air conditioner is well-ventilated and free from obstructions.
-
Checking the thermostat setting and ensuring that it is set no lower than 65 and no higher than 75 degrees.
-
Making sure the air filters are regularly replaced and that the air in your home is free from allergens, pollen, or other air pollutants.
-
Checking the air conditioner’s ducts and vents to make sure they are properly sealed and that there are no leaks.
-
Having your air conditioner serviced by a professional at least twice a year.
HVAC Technician’s Recommendations
When it comes to avoiding any potential issues with AC blowing air but not cold, it’s important to consult with a certified HVAC technician at least twice a year. An experienced technician will be able to make sure that your air conditioner is in good working order, and may even provide additional recommendations on how to improve the efficiency of your system. Some of the things a technician might recommend include:
-
Checking the coolant levels and ensuring that they are adequate for the system.
-
Testing the system to make sure it is working correctly and cooling the air efficiently.
-
Replacing any worn or broken parts. Doing this regularly will help to ensure that your system is able to run at optimum efficiency.

-
Cleaning the condenser and evaporator coils to ensure they are not clogged and working efficiently.
-
Checking the fan blades and belts to make sure they are not worn or damaged, and replacing them when necessary.
