The AC unit and condo were new 6 years ago. I started working nights last winter and now come summer and 90F+ daytime temps i'm finding the AC is not keeping up.
1200 sq ft top/2nd floor condo will be around 75° when I get home at 6am. I'll turn it down to 68° when i go to sleep at 9am. After 6 hours or so of sleep I get up and the condo will only be down to around 72°.
I've never had the AC serviced professionally (or done anything but change filters), am I overdue for basic maintenance or maybe a bigger issue?
