Project Location: Blacksburg, SC
My air conditioning runs, but it's not discharging cold air, but rather just slightly cool air. It does work somewhat, but feels as if it needs a charge. I usually don't have it set very low because I prefer it a bit warmer, but it is still struggling to keep things at 77 degrees.
