We are building a house and are receiving proposals on the HVAC system. Obviously, each contractor has their own preferred units. My question is how do I determine the best manufacturer for my project?
I thought I was pretty well set thinking I would go with a high efficiency condensing unit, specifically the Peerless Pinnacle. However, I've been told that Buderus and Viessmann are a more premium product. I'm allowing additional room in the budget to pay for a high end unit, but I want to spend smartly.
Recently, I got thrown by someone telling me I should stay away from condensing boilers (this person is impartial). His statement was that the condensation is acidic and deteriorates the components. He suggested going with a conventional boiler since the energy savings between 85% and 95% AFUE would not make siginficant differences in the energy bill.
The only thing I'm sure of is that I will always second guess my decision. Is there any way to determine the BEST system.
