Reasons air conditioners break

The most common reasons why air conditioners struggle to cool a home during hot weather are due to low refrigerant levels, dirty coils, clogged filters, or faulty fan motors.

Low refrigerant levels can cause the unit to become inefficient and not produce enough cold air.

Dirty coils can also cause a decrease in efficiency, as dirt blocks air from passing through and reduces the air temperature.

Clogged filters trap dust particles and block the flow of air from passing through, resulting in an increased load on the unit and less cooling power.

Faulty fan motors can reduce airflow within the system, again resulting in a decrease in efficiency.

Make sure the unit is properly sized for your home

It is also important to make sure that your air conditioner is properly sized for your home. An undersized or oversized unit can cause both inefficient cooling and excessive energy usage. If you suspect this might be an issue, contact a professional technician who can help you determine the right size A/C unit for your home.

Inspect the ducts for leaks or damage

Leaky or damaged ducts can cause your air conditioner to run inefficiently. Poorly sealed joints, holes in the ductwork or disconnected ducts can all let out conditioned air and make it difficult for the unit to cool your home properly. It is important to have an HVAC specialist inspect your ductwork regularly and repair any damages.

Finally, it is important to remember that regular maintenance on your air conditioner is the best way to ensure optimal performance and avoid any cooling issues during the hot summer months. Cleaning the coils and changing out filters regularly can help increase efficiency and make sure your unit is always in tip-top shape.

Check the filters and make sure they’re clean

The first and easiest thing you can do to ensure your air conditioner is running properly is to check the filters. Dirty, clogged filters will reduce the efficiency of your unit and decrease its ability to cool your home.

Make sure that all air vents in your house are open and unblocked, as this will help increase airflow. Additionally, change or clean the filters every month to ensure that they are clear of dust and dirt.

Check the thermostat to make sure it’s set to cool

It’s easy to overlook the thermostat, but it can have a major impact on the performance of your air conditioner. Make sure that you check the thermostat and set it to cool mode. This will ensure that when it senses hot temperatures, it automatically kicks in and starts cooling your home.

Make sure the vents in your house aren’t blocked and that the air is flowing freely

The vents in your house should not be blocked, as this will reduce the airflow and make it harder for the air conditioner to cool your home effectively.

Check all air vents and make sure they are open and unblocked. Additionally, move any furniture or other items that may be blocking the outlets. By doing this, you can ensure that the air is flowing freely through the vents, allowing your A/C unit to work more efficiently.

If all of these things check out, it might be time to call a professional

If all of the above steps fail to address your air conditioning issues, it might be time to call a professional for help. A skilled technician will be able to diagnose the underlying issue and provide you with a more permanent solution.

They may also suggest repairs or replacement parts that can help restore your unit’s efficiency and overall performance.


In conclusion, if your air conditioner is not cooling as it should, don’t panic! Follow the steps outlined in this blog post to diagnose and troubleshoot any issues with your unit. From checking and cleaning the filters to making sure that all vents are unblocked, there are plenty of DIY solutions you can try before calling in a professional.

 We hope this blog post has been helpful in getting you back to feeling that cool air again.
