Central AC Quote--Right Price?

We just got a quote from our HVAC guy for $30K for a 4 story house (18X40). 3-4 zones. Does this seem about right?

Comments

Sorry, I don't have an answer, but I'm wondering how much the total cost of central air is beyond this estimate. I mean, the ductwork, electricity, and everything else from start to finish? I was told that total cost for this for a 4-story brownstone (that currently has nothing) can exceed $100,000, even if the ac itself is only $40 - $50,000. Anyone have a good estimate? Thanks.

I have heard 30K as a ballpark so that may be right.

Sounds much too low. $30-$40k is just for two units of a 3-br condo including ductwork.

I have no idea who you guys have been talking to or using. I have a 4 story house and while we only have 2 floors done in central A/C and heat (3rd floor was occupied with tenants) the 2 floors only cost $10,000 soup to nuts. That's not an estimate. I would also add that our walls were wide open because we were doing a gut renovation on the garden level so that may have brought some of the cost down. I'm sure getting a unit strong enough to push air all the way up to the 4th floor is some of the cost, but.....

A good way to price out A/C (only) is about $2500 per ton.
Typical tonnage per 400 square feet is 1 ton. Most brownstones take 2 tons per floor. Top floor usually takes 2 1/2 tons because it's always hotter on the top floor.
Be careful of who you choose and get at least three quotes. Pricing should be very similar. It's the personality of the contractor that you are trully shopping. To find one you can trust.
