To understand why your air conditioner’s cooling might be deteriorating, you need to know about Freon, the substance with which any air conditioner is charged. From the point of view of thermodynamics, an air conditioner is a heat machine, and freon is its working body. It boils, condenses, and boils again in the heat cycle, thus cooling. Freon leaks cause most problems with air conditioner cooling. Where freon escapes from the air conditioner is usually where oil leaks. When 150 grams of freon out of 700 grams are gone, the cooling will noticeably deteriorate, and with the loss of another one hundred and fifty will almost disappear.

I assume that it is a technical issue, and you will have to find a specialist that can help you to inspect the air-con and to establish what is the solution. I had a similar problem and because of lack of knowledge, I decided to throw it. Thankfully my friend came to me and recommended checking this site airconservice.com.sg. I contacted the company I was recommended by my friend. A specialist came in less than an hour, and he fixed the problem quickly. Most probably I would throw out my air con if my friend wouldn’t come to me on that day.

I had the same problem a few months back but managed to fix the problem with the help of an air conditioning in Tonbridge Company. Do you have a well-insulated attic? If you don’t or it is poorly insulated, this may be part of your problem.

The other thing may be attic ventilation. A gable end vent fan installation will cycle temperature and help you to significantly lower your attic temperature and add a heat load to the rooms upstairs.

More ideas… closing your bedroom doors could possibly help if in each room, there is a return. How many zones/thermostats are there? If you only have one, with a cool downstairs and hot upstairs, you could shut down a bit on the downstairs vents so as to allow more air in your upstairs. This will also enable the thermostat to get a representative sample. Leaving the doors upstairs closed will ensure that cold air up there does not fall downstairs to cool it further, which may cause the AC to prematurely cycle.
