HVAC in the attic?
Comments (24)Mighty Anvil asked....What kind of HVAC system? Is there perimeter eave space around the second floor perimeter? I don't know as of yet what system will be used. Probably something rather standard. And there won't be much eave space as I see it. (please see link... Our plan is a stretched version of this plan, with the bathroom moved to where the bedroom is now and the plan stretched another 12 feet to make room for the bedroom that the bathroom pushed aside.) As we have drawn the plan now, the living room goes from gable end to gable end, and we'd like to vault that one room's space. In other words, there will be two zones of attic space....one above the kitchen... and one above the new bathroom and bedroom. The vaulted living room will cut these two attic spaces from each other. Only one 8x8 bathroom AC'd on the bottom (garage) floor. However, we are considering a temporary (5years) guest bedroom downstairs. Considering a window unit for the temp room. No basement and sited on the MS gulf coast. Hot and humid. Thanks for ALL the responses... Gary and Frog... I will look at the links tomorrow. ....Spidey hearing ....!!!

Comments (14)I had Strand Brothers come by. They were excellent to deal with. Their sticker is on the unit, so I called. The guy came by and confirmed what y'all posted above about having 2 6in duct tubes, one high, one low. One is in place, the other I may have put in, so I can close in the ceiling so no more insulation falls in. He said that since the door has a good gasket seal and since the small closet is insulated, I won't notice any difference in the a/c bill if I close in the ceiling. I may do it anyways, just for aesthetics. Thanks for your help here. Mason...See MoreSingle HVAC zoned or two HVACs without zoned system
Comments (27)The biggest problem with HVAC zone systems is knowing when to choose it as a solution and when not to. Some HVAC companies it's about "sell, sell, sell" whether or not it works... there's more money in "sell, sell, sell" --- when it's only about money? So does the comment above mean I do it for free? No. If you think that you are reading things that aren't there. New construction? best to choose separate systems 9 times out of 10. In order for a zone system to work, you have to know what you are doing. Most HVAC companies staff (the techs they send you) are 20-30 year olds. How much practical experience could they possible have? It's best for HVAC zone systems to be an elegant solution. A HVAC zone system is a tool in the tool bag. Not all homes are suitable for zone systems. Some homes there is no other way, and in some cases complications to those problems will make an HVAC zone system design possibly more prone to problems. You have a problem now, do you want more problems. These decisions among others are decided "in person" --- so considering that becareful what information you decide upon from the internet. Just because it's here doesn't necessarily mean it's true. That said: Depending on equipment level chosen, how many different floors you have in your structure, how much room you have available... will all be factors that make you decide one way or another. From there it's in your best interest to pick a contractor that is skilled: especially when it comes to HVAC zone systems. (there's a lot of garbage out there.)

Comments (11)Sizing can be less of an issue when you have multiple units. Because each unit is controlled independently, provided of course the unit itself is not over sized for the area in which it serves resulting in excessive short cycling. In your case 3 ton plus 2 ton isn't necessarily equal to 5 tons of cooling... unless you drive those thermostats really low. By having two systems with total capacity of 5 tons (which, most of the time this would be oversized for a 1700 - 1800 sq ft structure) has a few advantages. 1. You have the ability to use one system only during low heat days or set the opposing unit higher. The unit set higher only runs if load conditions warrant.... meaning if it's not hot, the thermostat controlling the unit does not call... the unit can not run without a call... 2. Utility bills can be much less... because you rarely use both systems at the same time. You run the bedroom system when you sleep, the other when you're awake. If you have a home office in one the bedrooms you may need to rethink things a bit. 3. Extra capacity for when it's hot out. When it's hot you have the capacity to cool the home. (even while entertaining guests --- additional people add heat) Remember heat waves come, heat waves go... a so call 'properly sized' AC system is essentially properly sized roughly 10% of the time... especially if that system is a single speed AC system. Alot of people I come across like to sleep cool. So for that reason I doubt I would change the configuration of the space. Once you realize what you have, the choices you make are mostly budget type concerns. Essentially a set up like this runs like a 2 stage system. This kind of subject is above the pay grade of many... choose your contractor wisely. I service the Katy, Texas area....See Moreklem1
