hvac and furnace size and how many units - new construction
Comments (10)I find it strange the builder does not know what HVAC equipment will be supplied with the house. I sounds like you will have one furnace and AC condenser set up with two zones. This is better than having one zone, but not as good as having a system for each floor. Two independent systems cost more than one. The HVAC contractor is looking to save money. Zoning can work if it is done properly with the right equipment. The problem is most HVAC contractors are not good at zoning. I would also push for two systems. They will be smaller, maintain temperatures more consistently, and save some money on heating and cooling costs....See MoreWill I regret going oversize on new gas boiler?
Comments (2)I assume this is a hot water system and not steam. I am a homeowner and not an expert, but you have to be careful about matching the size of the boiler to the amount of baseboard. You should discuss with the HVAC contractor how this will affect the performance. I suppose you can think of the extra manifold being connected to a separate zone which is never enabled. Boilers have long lives, so I would not be worried about reducing it. I grew up in old houses which had oversized boilers. They seemed to last forever....See MoreNew Construction Water Meter Size
Comments (1)You should not choose... Your plumber should do a code "Fixture Demand Load" study prior to pulling a permit to install the water supply line and the code will define the required diameter of your supply line. The meter should then be sized equal to the supply line. The exception is 3/4" is the minimum size permitted for a supply line, but in instances where the fixture load demand is minimal, they may opt to install a 5/8 meter on a 3/4" line....See MoreNew Construction- best value window sizes?
Comments (3)All of the windows you see in the size charts from the various companies are available at no particular premium for the different sizes other than the obvious fact that larger windows cost more and the larger they are, the less they cost per square inch of glass area. For instance, the most expensive Andersen double-hung is their largest one but it is also the cheapest per square inch of glass area. Andersen also sells their "cottage style" (smaller upper sash) windows at about 13% less than the equivalent regular style of the same size. So, first you should determine the amount of glass you want, then the desirable head and sill heights, and then size the window widths in standard sizes to achieve that glass area with as few windows as possible, in reasonable proportions, and then consider making them cottage style....See Moreisabelle_daybreak
