Why is the aircon not cold?

There are several factors that can cause the aircon not cold enough. Imagine spending all day in the sun and all you want to do when you reach home is to chill in a cold air conditioned room and yet when you have switched it on for more than 30 minutes, it is still not cold! Frustrating right?  There is literally no cold air from the air conditioner. Nothing at all!

Well there are a few possible factors contributing to this “hot aircon” issue. Read on and check if any of these is possibly affecting the cooling air system.

Most common reasons as to why is the air conditioner not cold are:

1. Clogged air filter

Air cannot flow through properly thus greatly affecting the cooling capacity. It could be due to too dusty and such as happen especially if the air conditioner is switched on with open windows.

2. Dirty condenser coil

Dirty coils that are loaded with debris are unable release heat outside. As the coil get dirtier the air con will be more less and less effective.

3. Coolant running out

Coolant flow through the evaporator coil to cool the air flowing through it. When the coolant run low, the air coming out of the air con in turn also get less cold.

4. Compressor breakdown

Compressor is the heart of the air conditioner. It circulate the cooler around the coil.

5. Small air conditioner

Size does matter. A bigger room require a bigger aircon. If you place a small air conditioner in a big room, it is going to be less ineffective.

6. High environment temperature

When the environment temperature go over the optimum temperature limit, the air con might even stop working.
