This company is irresponsible and incompetent - stay away from them! I purchased a gas furnace in May of 2013 and had several installation problems. I later discovered the company did not install a filter rack, but they failed to show-up to install it. I hired another company to perform the work, which involved the replacement of all of the venting work above the furnace. Then I discovered the furnace does not operate - the LED caution light indicates major problems. The company I hired to look into it is recommending replacement of the entire furnace because the furnace was improperly installed and the repair bill is likely to exceed $1000.00; High Efficiency Homes will not honor their warranty on parts or labor. Long story short; I paid $4,300.00 (and counting!) for a furnace that has never operated.
