Bob Blanchette replied to Jon LaMonte's discussion Are Zoned Heating/Cooling Systems a Good or Bad Idea? in the group HVAC"2 systems is normally not much more if any more expensive than a properly designed zone system. Upstairs systems can use options such as heat pumps or air handlers with hot water coils. Even electric strip heat could be an option in areas where…"
tedkidd replied to Jon LaMonte's discussion Are Zoned Heating/Cooling Systems a Good or Bad Idea? in the group HVAC"Bypass ducts are beginning to be recognized as a very energy inefficient design and bad practice to be avoided whenever possible. I see you've just joined Allison's group - I think he might have a blog about this. "
Chris Heenan replied to Jon LaMonte's discussion Are Zoned Heating/Cooling Systems a Good or Bad Idea? in the group HVAC"Zoning has benefits beyond temp control. Most often the home does not require the full 2 stage heat or cooling as the system only needs to satisfy a portion of the home. So, then if 1/2 the heated air goes through a properly sized and balance…"

Bob Blanchette replied to Jon LaMonte's discussion Are Zoned Heating/Cooling Systems a Good Idea or a Bad Idea?"Oversized equipment sucks from a comfort prospective, especially for gas furnaces. The heat comes on, blows you out of the room, then it's freezing before it cycles again. Furnaces do tend to be sized for CFM in the southern climates. A 45,000…"
Bob Blanchette replied to Jon LaMonte's discussion Are Zoned Heating/Cooling Systems a Good Idea or a Bad Idea?"Some of the benefit to 2 stage A/C units is the "oversized coils" in relation to compressor size when the unit is operating on low stage. If a 2 stager unit is 2ton/3ton you have a 2ton A/C system most of the time with 3 ton sized…"
Chris Heenan replied to Jon LaMonte's discussion Are Zoned Heating/Cooling Systems a Good Idea or a Bad Idea?"Jon,
Answer to your initial thread question: zones are good. MUCH better than oversizing.

Building Science Proven by the Bug Man
A buddy of mine, Dennis, that’s an exterminator called me the other day while I was standing in Home Depot. “Jon, I’ve got a problem and I need some of your building science expertise.” The problem he was having was being caused by some granules he had put down to repel some flying squirrels.

Auditors Offering Contracting Services - Conflict of Interest?
This very question was recently posed in the BPI Group. Is there a conflict of interest when an energy auditor also offers contracting or weatherization services to their clients? At first glance, many would say that the easy answer is "yes". The common reasoning is that people will steer their clients towards the products they sell in order to make as much money as possible. After all, that's what we are all in business for, isn't it? The other answer was "it's just human…
