I have been having trouble with my AC not being cold and not very much air blowing out. I live in a typical bi-level that they through up back in 60's. I have had checks, and duct cleaning, and the tech says everything is fine, but when the outside temp is above 80 it will run non stop all day and not get the temp down below 75.
I only have 2 returns, one in the basement next to the furnace, and one right above it on the floor in the hall. Both returns are good size, but it seems the fan is pulling hard. My house is about 1800 Sqft and I have a Bryant plus 80 if that tells ya anything.
I am not familiar with HVAC systems, so I am not sure what other info is needed to help. Thanks, Dave
Can you give us the model number off of the outdoor unit? Then we will know what size system you have.
The model number of the furnace will tell us what size blower you have.
Does the 1800 sqft include the basement?
How many supply registers are there?
Do you have a digital thermometer that you can take some measurements with?
