她們總是把溫度設在68-72度。這個在我們這裏酷熱的夏天完全不practical也不responsible。暗示她們幾次了都被忽略。她們住了兩年我起碼帶AC公司去小修了三次,當然每次AC公司都會誇大一下問題 把話題往replacement上引。今天氣溫達101度,tenant又來短信說她們溫度設在69度,ac有停機的跡象。我這次把話挑明了:
I just talked to my ac guy and here’s what he suggested:
Most residential AC units are designed to handle about a 20 degree difference between outdoor and indoor temperatures efficiently. If we try to cool from 101°F to 69°F the AC is pushing the system beyond its designed capacity.
The system may run no stop to try to reach 69 which will cause issues like Coil freezing, Compressor overheating even Premature failure. The coil freeze can cause ice buildup and system shutdown.
So he suggested to run AC temp no lower than 78 during the peak heat like this week. You may use ceiling fan to assist cooling. Blackout curtains will help too. He also stressed to change filter monthly to keep the vents unobstructed.
I can deliver some filtered tomorrow or Friday if you need.
剛剛給她們renew了lease 現在後悔怎麽沒把這個寫進新lease裏!
