We're recently purchased a new home currently just in final framing stage in CT. The heating and AC system was already specified in our contract (albeit generically). I was recently cautioned by a friend to check the equipment specs to evaluate if the builder is using options that are sub-optimal. I recognize after reading the post on this site that the installation is the most important thing and I don’t have a choice on the Company other than to trust my builder’s reputation which is very good. I requested and received a more detailed spec sheet from my builder. I'm considering whether or not it would make sense to upgrade anything in the existing system. We’ve decided to add spray-foam insulation so the builders already given us a large up-charge for insulation and another large up-charge for modifications required to the AC system (principally adding two Aprilaire 8100 whole house ventilators due to the closed air environment). Here are the details on the system:
Burnham MPO231 Oil Fired Boiler – 87% Efficient
2 EWC 2 zone electronic dampering systems
2 Heil 4 ton air handlers (no model specified)
1 Heil 3 ton air handler (no model specified)
1 Heil 4 Ton Condensing unit – 13 Seer (H2A348GKA)
1 Heil 3.5 Ton Condensing unit – 13 Seer (H2A342GKA)
1 Heil 2.5 Ton Condensing unit – 13 Seer (H2A330GKA)
1 Superstor 80 gallon indirect fired hot water tank
3 Aprilaire 2200 Media Air Cleaners
5 Honeywell Pro-4000 Programmable thermostats
1 General 1099 Humidifier
I’ve been reading a lot of the post on this site (a little info is dangerous) and I’ve currently focus my query to thermostats (Perhaps an upgrade to a Honeywell 8000 series makes senses given auto air circulation features etc) or an upgrade to Aprilaire Model 700A Humidifier versus the General 1099 humidifier? Any other “upgrades” I should be considering in light of the above?
Would an investment in any of these upgrade or any upgrades be worth the investment? I’m really seeking guidance on the right things I should be requesting from the HVAC contractor. I’m not quoting the job so I won’t have the benefit of the data points from multiple HVAC contractors.
