My central air conditioner has a hard time cooling my upstairs. Any ideas?
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.
