New Construction HVAC Question

12k

just had a complete replacement of outdoor and indoor units and all duct work in house for about $22K two years ago. Not sure if twice the equipment would mean twice the price, so say around $35K ...?

ETA: we used Carrier systems, natural gas heat, and the 22k included demo of old system.

I'm building a house. Can someone give me a FAIR price for two (2)- 3.5 ton HVAC (natural gas heat), complete installation using flexible duck work and 16 seer top type brand like American Standard or Carrier?

Why dont you just get like 3 mechanical contractors to give you an estimate?

Pick the one you feel most comfortable with. Do you want rec's for mechanical contractors?

Because I have a guy I really want to use. He is working up a price and when he gives it to me I want to know in advance it its fair. If so, I will definitely hire him because of his reliability and reputation.

Sounds like you're not really sure about the latter.

Imho a ballpark for trane/American standard would be 15k.

You don’t want flex duct Op, as little as possible. It’s not nearly as efficient.

The units should be about $10k, it’s impossible to quote you beyond that without having your house floor plan.

DO NOT only get one bid, lol. At least 3 if not 5.

2500/ton is a good rule of thumb, plus variables. anything south of 20K and you'll be getting a fair price

Unless that's a huge house, something tells me you're pricing regular insulation, and/or your contractor isn't estimating variable speed units. I just built a ~3,300sf house, and have a single 4-ton unit with 3-zones, variable speed. Made possible by spray foam insulation, which was the best decision I ever made. My electric bill is half of what it was in my prior house, which was less than half the size. Always comfortable.

HVAC cost me about $12K. Sprayfoam cost me about $11K.

16k I would guess

Did OP just out his alter?
