开利网上有很多差评。然而,如果你读消费者报告,Checkbook, Yelp或Angies List,他们装载了如何避免问题的信息。所有这些出版物/资源的共同主题是:大多数问题,可能超过90%,是由错误的安装和/或缺乏培训的人员或缺乏定期维护造成的。当我和朋友们谈论更换他们的设备时,我建议他们花26美元订阅《消费者报告》,或者花30美元订阅checkbook.org。他们的回答是:我不会花这笔钱。这是一种浪费。真的吗?你会花3000美元到10000美元来更换你的暖通空调系统的部分或全部,并冒着出现问题的风险,最终可能会让你花双倍的钱或痛苦地避免花30美元?更换维护过滤器,检查系统,清洗线圈等呢?很少有人给自己的设备检修,但大多数人会更换过滤器。 You should have your system totally checked out at least every other year. Would you drive your car 10-15,000 miles without changing the oil? You shouldn’t be surprised if you never maintain your system that you don’t have problems. In 2009, we installed a Carrier Infinity hybrid heat system with the above 2 stage 80 percent furnace, Infinity 19, 2 stage heat pump, Infinity air purifier, and whole house humidifier. I cannot say enough good about this system or the folks that installed it. It performs flawlessly, is extremely quiet inside and out, our utility bills are the lowest on the block and our house is very comfortable on all floors. About four years ago, we added the Carrier UV lights and I installed them myself. We have yet to have a cold or sinus infection but one or two times since I installed this system. Carrier runs promotions with cash rebates during portions of the year and there were tax credits galore during that time. The dealer that installed it and services it is a Carrier Presidential Award winner and the company has glowing reviews. The system has never needed repair. If you have a good company install it, let them come do the maintenance. Do your research before you call someone (and definitely don’t use Sears) and if you have problems–call a licensed, reputable Carrier dealer, not just any old company. I would make the same choice again with the equipment and the installer. More often than not good things are seldom cheap and cheap stuff is seldom good. Same for labor–good skilled labor isn’t cheap and cheap labor isn’t skilled. However, those folks who had Carrier condensing furnaces in pre-2010–those were riddled with problems. The two stage A/C and heat pump units that had Bristol 2-stage compressors—problems. Check with Carrier to see if there is recourse but always go through a properly licensed, reputable Carrier dealer.
