Help with AC choices?
We are doing an addition to our 2 story colonial in the Boston area (expensive market) that will be about 2400 square feet when completed. We are working with a reputable GC whom we trust and have a bid from his HVAC contractor (see below), who is also well rated on Angies List, etc.. Our house has never had central air before so I think most of the costs below pertain to the labor of setting up the systems and not just the AC equipment. We don't have a lot of time to obtain alternate quotes. We may be naive but we do trust our GC that his HVAC guy, though not likely to be the cheapest, will do a quality job.
We've been encouraged to consider the most expensive option if we care about humidity and efficiency. Lowering humidity has high value to us -- it's humidity that we hate and we could easily imagine keeping a warmer temperature so long as the air is dryer -- we don't like the feeling of over-airconditioned spaces.
Does this seem like a reasonable bid? What questions should I be asking?
To furnish and install one (1) York 2.5-Ton Air Handler, Model #AHR30B3XH21 and one (1) York 2.5-ton Condenser, Model #YCJD30S41S1H (13 Seer).
To furnish and install insulated sheet metal duct work with six (6) supply outlets to Second Floor and two (2) supply outlets to the First Floor.
To furnish and install one (1) Trion Air Bear Filtration System.
To furnish and install refrigeration piping from indoor coil to outdoor condenser.
That basic bid is about $13,000
1. To upgrade Air Handler to M#AVG48D3XH21and Condenser to M#YCJF030S41S1H (16.25 Seer).
this next option bumps only slightly to $13,750
2. To upgrade Air Handler to M#AVG48D3XH21and Condenser to a 2-stage Condenser, M#CZH03611C (18 Seer).
this jumps the price to $15,600.
