So let's say we have 3 different contractors who offer Lennox, Trane, and Frigidaire that are all reputable and do the same quality work on their installations....you would prefer the Lennox?

Thanks beenthere. That's why I wanted to ask before I posted the price difference.

tedkidd, we have 24" overhangs on the whole house. We also have a front porch that covers 2 of the front windows and a back porch that covers two of the back ones.

The other two in the front...

Beenthere, am I able to ask if the 17.6 SEER system is XXXX amount of dollars more than the 15 SEER system does it make sense to go with it?

Like I said I know prices aren't allowed, but I'm not...

Zero and genduct, how about your thoughts on the proposed systems. Both of the Lennox systems were suggested by one contractor and both of the Luxaire were suggested by a different one.

Hoping for some feedback on the 2 suggested systems.

HVAC pros familiar with humid southern climates would you do it the same way or differently?

We were told that we could go with more foam in the walls (5 inches), but it might not provide the ROI and to put the money into a better HVAC system.

We have low E with argon gas vinyl windows...

We've heard that quite a lot, but so far it's been really good. The motto has been to expect the unexpected because this is our first rodeo with all this and lots of unexpected stuff has come up.

We have metal framing on the interior as well. The system we used calls for 4 foot OC and there is hat channel running horizontally spaced every two feet on the inside and outside of the studs.
...

We are going with the same open cell foam for the entire envelope. I don't know that our foam contractor even offers closed cell.

Is there a reason we shouldn't use the open cell for the walls?

We are planning to use around 3 1/2" in the exterior walls and 5" under the roof deck.

The 3 1/2" in the walls won't have to be shaved because our walls are 8 3/8" thick.

Mirage, how thick are...

Thanks for the response ZeroTolerance.

I've tried to be well educated throughout this process, but that doesn't mean that some contractors aren't misinforming me either knowingly to sell me...

Mirage,
I've only seen one other ICF house in the building process and it was a heck of a structure. We considered that route, but it would have busted our budget.

We went with a completely...

Our metal framing system doesn't just replace wood with steel. Our exterior walls are 18 gauge 6" galvanized steel studs at 4 foot OC with 1 1/2" hat channel on the outside of them and then 7/8" hat...

Came across this thread and not wanting to hijack it, but I had a question related to using the spray foam directly under the roof.

We are in East Texas which has high humidity and planning to...

Talked with a local company today. Feedback is welcome.

This was all done over the phone and he said he would have to sit down with us and go over things more in detail.

I told him our...

Number of occupants for the house is 5 and most of the time there is someone at home.

Our ceilings are 8 foot with three different areas having recessed (tray) ceilings that make them 9 foot.

I read over my previous post and hope I didn't sound arrogant.

I'm just concerned that we will choose the wrong contractor and want to make sure that I know what to look for and what questions...

Well we have 5 bedrooms :)

Please feel free to ask any and all questions that come into play. If this were a website, I'd be able to offer tons of advice.

That's why I'm coming to you pros...

Thanks Shophound. We have quite a lot more humid days than not...even in winter sometimes.

Would the devices TB is referring to dry the air out in winter? Are you suggesting I need a dehu as...

You two are among the ones I was hoping would respond to my post. The two contractors that we've talked to so far both said they've got quite a bit of experience with spray foam, but I spent about 4...

My wife and I are building our own home (subbing everything out ourselved) and are already "in the dry". I have been trying to educate myself as much as possible throughout every step of the process...
