Why is the aircon not cold?

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.

Well there are a few possible factors contributing to this “hot aircon” issue.

Most common reasons are:

  1. Clogged air filter

    Air cannot flow through properly thus greatly affecting the cooling capacity.

  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.
