Central Air Not Working Upstairs

Attic fans are overrated and can cause more problems sucking air conditioned air out of your home.

Central air not working upstairs. It's about 15 years old and In order to get your home back in the cool zone, let’s take a look at some common reasons (and solutions!) your a/c isn’t cooling down your second story. For the past couple of nights the heating in my house has been working fine upstairs (all the upstairs radiators heat up properly) but nothing.

The vents are closed in the basement, since it’s not used as living space. Physics is the challenge here, because hot air rises and cold air sinks. Closing all the downstairs registers may help the hot upstairs a little, but your air conditioning system may suffer from inadequate airflow.

It happens because of the laws of thermodynamics. However, the opposite has happened. The living room return is at the bottom of the steps.

You’re eager to retreat into your cooled down space, throw your feet up on the couch and enjoy a sweet drink… only to find that the air coming out of the vents isn’t that strong and the inside of your home is almost as hot as the outside. Unfortunately, they can be expensive to repair when something goes wrong. Be careful not to fully close all downstairs air supply registers.
