The Air Condition system consists of many tiny components on which the whole system operates. As we look deep into what causes the air conditioning system to malfunction are:

1. Dirty HVAC Filter

The number one reason a home becomes uncooled is when the air conditioning filter gets dirty, plain and simple. Many homeowners think they only need to replace the filter once it stops cooling the home adequately. But remember, if you have air conditioning, that means your system is running longer cycles to cool the home which shortens the life of the air filter.

2. Thermostat Malfunction

Did you know that there are a few steps you can take to make sure your air conditioner is working correctly? Check the thermostat first by checking the batteries and making sure the unit is set to “cool”. If you are still experiencing issues, check your filters to ensure they aren’t clogged. If you have done these checks and are still experiencing issues, call a professional immediately since it may be time to replace the system.

3. Evaporator Coil Issues

The evaporator coil is a component of the AC system that is essential in the removal of humidity from your home. The evaporator coil is located inside your home near the furnace of the HVAC system; it absorbs heat and humidity in the air that is sent outside. The evaporator coil then sends cool air into the house through the duct system. If the evaporator coil is dirty it will not absorb the heat and humidity like it should, which causes several problems.

4. Dirty AC Condenser Coils

The condenser unit is an important part of your central HVAC system. Condenser coils are located outside of your home in the air conditioner unit. Because of the location, they can become dirty due to outdoor elements like dirt and seasonal debris. If there is too much dirt build-up on the condenser coils, it will cause higher utility bills.

5. Refrigerant Leaks

Air Conditioner breakdowns can occur for many different reasons. One of the most common AC problems is a refrigerant leak. Below we will take an in-depth look at several of the most common causes of an air conditioner breaking down, and if you are experiencing any of the below issues, please contact your local HVAC technician, to determine what may be the cause of your AC not working properly. For more information about leaks, you can visit many sites on the internet or if you live in Israel, you can call 1-700-500-670.

6. Clogged Drainage Line

Did you know that the HVAC filter is often the cause of most AC and furnace problems? Did you know that checking the drain pan is one of the quickest things an HVAC technician can do to prevent expensive AC repairs? The drain line on your air conditioning system could be clogged and need to be replaced.

7. Bad Capacitor

The Capacitor is the heart of the air conditioner that sends electrical energy to the fans and compressor. If it shorts out, then it can ruin all the other parts of your system. The symptoms associated with a bad capacitor include: the compressor will not run, the unit does not turn on, the unit freezing up, the cooling and heating functions of the unit failing to activate, a clicking sound, and the smell of something burning.
