Amazing system that I'm sure will a name for itself over the summer period. It's a lot cheaper than you'd expect to pay for roof ventilation and is surprisingly simple to set up. Superior to Whirybirds, (which are overhyped in my opinion) and the effects are noticed substantially on a warm days. Of course experiences vary for everyone and the HDS won't be as effective on older homes that might have bad insulation and other flaws. But for me I'm certainly noticing I'm using the air con less

One of my best school mates, Casey had me wondering a few days ago about whether I should get a residential ventilation system for my home. It used to get way too hot in the summer and the air conditioner seemed to be overworked. When she illustrated the effectivenes with which the system works and maintains suitable temperatures at all times, I thought I'll go with my gut and take a chance at having one of HDS Advantec's ventilation systems set over at my place.

It's funny how one simple decision can make things so much more comfortable. The heat dispersing system warded off the heat and kept steady during the winter. Brilliantly innovative. Thank you Casey, for introducing me to HDS' fantastic ventilation system!
