现在,让我马上说,这个单位是全新的。到现在还不到12小时。但是,在那12个小时里,它成了我的新闺蜜。首先,我们住在东田纳西州一所2000平方英尺的房子里,夏天气温高达100华氏度,去年冬天降至零度。我们的热泵在这个地区不太好用。此外,夏天大部分时间湿度都在90%,你就有了杀死热泵的秘方。所以,我们的老家伙10年多一点就死了。它(在我看来)从来都不够大到可以容纳这所房子(我们三年前买的房子)。这是最初的热泵)。温度永远不会低于70度,即使我们把温度设置在70度以下。 And, it had to kick into emergency heat a lot during the super cold days of the winter. The new unit was installed on a humid July day, and took the house from 75 (all doors and windows open just before) to 70 in about 2 hours. Also, dropped the humidity like a rock. It sounded like a water fall going through the pump's external hose. Our contractor recommended the York, and my husband was used to seeing them in large, industrial applications as an electrician. He said they ran no matter what. So, we'll see how it lasts. With the fantastic warranty, I imagine we won't have any issues.
