Modern Air conditioning systems, even the simplest ones, are highly complex equipment comprising of a combination of electric and mechanical components.
There are many things which can go wrong and prevent one from working to its full potential . Compressors, fan motors, electronic controls are just a few of the important components which can fail on poorly designed and manufactured air conditioner.
When you purchase a new air conditioner make sure the warranty is water tight.
Some “No Name” brands on the market sound cheap to buy but the dollars really add up when systems fail just out of warranty and parts are not available to repair it.
This will result in a complete new system having to be installed.
Stick with the brands you know ..
We use and recommend PANSONIC and MITSUBISHI.
