1800sf townhouse, 2 levels, a/c American std condensor 2 ton, 2016, Furnace American Std.
Thermostats target 75F, stuck at 77F for 3 hours now. What can be the primary issue?
BTW, his household energy usage is 209% higher than average. It does not make sense to me. What can be an ease solution. He purchased the TH two year ago and have the issues since then. This is the first time I observe the issue in person. Many thanks!
s设置室温75F, 停止于77F已有3个小时以上,a/c持续工作。孩子2020年入住,一直由此问题。他的用电量是临近平均值3倍以上。请问主要问题是什么?从哪里着手解决?孩子已经请过3波师傅,没有人真正解决问题。十分感谢!
