Air conditioning is a necessity for many of us today.

We rely on it to keep our homes and offices cool during the hot summer months, so when it breaks down or malfunctions, we are left with no other option but to get it fixed by an air cond contractor in KL as soon as possible.

There are many different problems that can occur in an air conditioner, and below you will find information about some of the most common ones:

AC Unit Refrigerant Leaks 

One common problem that may occur with your cooling system is a refrigerant leak.

Your refrigerant works by transferring heat from the inside of your home or office to the outdoors.

When a refrigerant leak occurs, this will cause you to lose cool air and it can also lead to other problems such as an increase in energy consumption.

If you have a problem with leaking refrigerant, be sure to have it checked right away, for you to avoid paying costly repairs and even higher energy bills.

Also, a fire-out break may occur with leaks, so it’s vital that you have it fixed before this situation happens.

Cooling System Drainage Problems

You might not be aware of this, but your AC unit actually has a drainage system that helps in the process of preventing mold.

If your drainage system is blocked, then it will cause water to leak into the ducts and create a moist environment for bacteria growth.

This can result in an increased risk of respiratory illness or allergic reactions.

Ensuring that you are taking care of any clogs or issues with the drain should help prevent unwanted things from happening.

The common reason for drainage problems is items such as leaves, dirt, or hair that gets wrapped around the grill at the bottom of your unit.

This can be fixed by using a wire hanger with an object on one end to scrape it off and remove any blockage that is present.

Frozen Condenser Coils 

Did you suddenly notice that your airconditioner isn’t cooling as much as it used to?

This could be caused by the condenser coils freezing up.

To address this issue, you will likely need to call a technician, but there are some things that can help prevent this from happening in the first place.

One would be ensuring that your outdoor unit is properly insulated during the winter months in order to help it maintain its temperature.

It is also important to keep your condenser coils clean and clear of any obstructions, such as leaves or dirt, that may be blocking the flow of air around them.

Frozen condenser coils can be a headache, so be sure to act fast and take the necessary steps to avoid this issue.

Dirty Airconditioner Filters 

Your cooling system’s filters are a vital part of your AC because this is what keeps the air clean and fresh as it circulates through your home. Not only do dirty or clogged air filters reduce airflow, but they can also cause damage to your AC unit itself!

It is recommended that you change the filter in your system once every month during the summer months when allergens are high and twice a month if you have pets with thick, heavy fur.

Filters should be replaced more often if you have children or pets because they are exposed to a lot of allergens from other sources, such as school and daycare.

In addition to changing the filters in your AC system regularly, it is also important that you clean them with soap and water every few weeks so that you don’t have to worry about bacteria and mold growing on them.
