Our home is 1 1/2 years old. We will be entering our second summer here shortly. Last summer our HVAC upstairs started blowing warm air. The tech came our checked over everything and finally said it had low freon and so he charged the system... Worked fine and now since we are starting to use our AC again, it is blowing warm air again (73 degrees). We keep the air on 70 so obviously it will not cool until late at night. (we are in hot GA).
I will be calling the company who installed it to fix it, but I want to know, I am sure this should not be happening so soon... So could it be leaking freon during the year. We have a downstars unit that has had no problems at all.
Thanks for any help
