我有一台用了8年的伦诺克斯热泵系统。在过去的6年里,每年都有一名维修人员被家庭保修人员派来2到4次。我认为他也是问题的主要原因之一。三年来,热泵上的散热片已经碎成了粉末。装有线圈的室内机正在漏水。当然它是R22冷却剂,所以机组需要更换。要是政府不再那么严格地监管一切就好了。当然,它不在保修范围内&我有一个家庭保修,只会更换线圈,而不是冷却剂。我想这是我的错,工厂和服务人员的工作很简陋。这是非常低效的,因为冷却翼是在热泵上大约1英尺从底部向上一直到整个装置。 Another problem is it is hot & humid in middle Tennessee & since I live up on a mountain away from all the bs, no one will come out. I guess they are afraid if they get on top of the mountain that they are thinking they will fall off of it. I have called all makes dealers for a new replacement & they won't call back or come out. Heck some of them don't even answer their phones. I lied Carrier did come out, huh. Been without A/C for over a month now. Don't waste your money on a home warranty, buy the best units you can afford & for sure get a good honest knowledgeable service company to install it. The latter I think is most important. I will get off my soap box now. Adios
