Unusual Behavior to My Central Air Conditioner

by Victor R.

Central air conditioner unit is running weird. First the rooms weren’t getting cold, so I called in a technician and he put in Freon. After a day of coolness it started to get warm.

The reading on the thermostat was increasing so I called in the technician again and he said it could be a bad thermostat. I brought a new one and it was installed. That work but for about six hour “literally”.

So I called the technician once more and he can’t figure out why it gets cool and stops working or continues to cool . We’re both stumped! There’s no leak and he said he put a lot of Freon to make it work. Can you help.
