How Come My Air Conditioner Isn’t Cooling the Home

Aug 9, 2022AC Repair

Air Conditioner Isn’t Cooling the Home?

When your air conditioning system or heat pump is not performing as expected, it may be time to call our air conditioning and heating professionals. Before you call someone to come out and inspect the unit, make sure you do the following:

  • Check Your Thermostat. Confirm the settings are correct and that you have it set to the desired temperature.
  • Check Your Outdoor Unit. Walk around the outdoor AC unit and check for debris. It is common for plants to grow too close and block airflow. Occasionally, after a storm or windy day, debris from your yard become trapped in the vents. Remove debris and trim back any plants that are near the AC unit. If anything is stuck in the blades or a blade is bent, call an expert.
  • Check Your Air Filter. A clogged filter affects the efficiency and performance of your air conditioner. Check it monthly and replace with a new filter as it becomes clogged with debris.

Possible causes of AC unit not cooling correctly

Condenser Coil

The condenser coil could be blocked or clogged if the air conditioner is not lowering the interior temperature as a result. In a properly operating system, the condenser fan pulls air from your home and pushes it through the condenser coil to extract the hot energy from your home.

The coil can become clogged with dirt, grass, and other matter that floats in the air. If your coil is dirty, you can end up with a reduced degree of energy efficiency, inadequate cooling during summer, or in extreme cases, a system shutdown or compressor damage due to overuse. If you do not have a hose, you can clear away debris or handle the coil gently while vacuuming it with a brush attachment. When the cooling system still doesn’t work, it’s probably time to call a technician.

Leaky Refrigerant

It may be a sign of a leak if the amount of refrigerant in your air conditioner is low. The refrigerant leaks from the unit and can be found in other areas of your home. The leak could also cause a buildup of humidity, which leads to mold or fungus growth.

An air conditioner that has signs of refrigerant leaks is not good for both the inhabitant and the environment. Make sure it’s quickly repaired if it leaks. It is imperative that a qualified HVAC technician diagnoses where the leak is coming from and fixes it.

It’s also possible for more refrigerants to be added to your air conditioning system. To ensure your air conditioner performs to its peak, you should make sure that you’re adding refrigerants that match the manufacturer’s exact specifications.

The AC company may recommend replacing the system with a new one, but it’s up to you if you want that done or not. You can choose to repair your current system instead of buying another one altogether for less money.

Sensor Failure

There are air conditioning systems that come with built-in sensors. When the sensor is displaced, it will no longer measure the air that enters the evaporator coils.

The sensor may stop working altogether if it has been knocked out of place or damaged in any way. It is crucial that you call for air conditioning repair as soon as this occurs to ensure your system continues to work correctly and efficiently.

If the sensors are not functioning at all, then there could be a problem with the compressor.

And, if your sensor is simply dirty and needs to be cleaned, this can also contribute to the ac not working correctly or as efficiently as it should. This will need air conditioning repair technicians, especially if you don’t know how to do it yourself.

Poorly Maintained AC Unit

Air conditioners are subject to wear and tear over time, so they require annual maintenance. Annual maintenance doesn’t just count ac repairs, but also cleaning and dusting the unit if necessary.

The ac unit should be cleaned regularly to reduce the amount of dirt and debris that accumulates on its exterior. This can also prevent mold and mildew from building up in your AC system.

Dust should be removed by a vacuum or compressed air, which will help keep the ac running smoothly and efficiently. Cleaning out your filters is vital for ensuring your ac is running at its best.

A regular maintenance service routine for an air conditioner will keep it in the best shape possible and reduce the chances of needing any repairs.

A malfunctioning air conditioner could need some repairs if its components have not been properly cared for. There is a possibility of a complete system breakdown if one component isn’t functioning correctly.

If any of the components are not working, this can result in a complete system breakdown and will need air conditioning repair technicians to fix it. If your ac is on its last leg, then you may want to start saving up for an AC replacement or new installation instead of just repairing it again and again over time.

Wiring Problems

A technician will be needed if your air conditioner has been installed by an untrained person who hasn’t done the installation very well or has not done the wiring that well. HVAC technicians will reinstall your ac system, so it is secure and free of safety hazards.

The ac is not working, and the repair person needs to check if any of its components are not functioning. If they’re all ok, then it could be a problem with wiring or electrical problems in your home.

Fire may be caused by bad wiring, which can also cause your air conditioner to lack the power it needs to run efficiently.

Outdoor Fan Failure

Using an external fan is crucial for your AC system to transfer heat from the inside to the outside of the home.

A fan that is not working can lead to a clogged condenser, which will prevent your AC system from running.

A malfunctioning outdoor fan could hinder the heat transfer and lead to your AC overheating.

The ac repair technician can do the job and check if the outdoor unit has any broken parts or wiring problems before replacing it.
