Excellent customer service

Purchased a central ducted system with a pre charged lineset and could not be happier...was shipped promptly and arrived fast and was undamaged ...had a few questions regarding the system, their online staff answered all the questions I had after the sale...it took a few weeks before I was able to get it installed...for a DIY system and me not having any HVAC experience, this was such a simple installation...Thank you Klondike !!
