Customer Question
We just paid a...

We just paid a technician to fix our unit for air conditioning outside but it still doesn't blow strong cold air on the upper level.

Contractor's Assistant: Did you double-check the thermostat's settings? And what about the filters?

It's a white Rodgers unit

Contractor's Assistant: Do you plan on doing the work yourself?

Well I think so, if we call back they'll probably charge us again

Contractor's Assistant: Anything else we should know to help you best?

We definitely need to go buy a new filter tomorrow, could that be the problem why the flow is so low on the upper level?

Hello, first step is to put clean air filter in it.

If that is not sufficient it likely that the air ducts to the upstairs are too small especially if it has not worked well earler.

.

Use a thermometer to measure the air temperature inside one of the registers down stairs and one upstairs, then use the same thermometer to measure the air temperature at the return air grill, from those results I can assess if the the damper is closed or the system might be slightly over charged with refrigerant.

.

We can go from there without a time limit, In depth with as much detail as needed , after you rate this answer:
