Building new home in SE Michigan. Approximately 4,200 sq feet 2 story house with 2,100 sq ft unfinished basement
Builder and HVAC subcontractor proposing following based upon Manual J results. Would appreciate feedback, suggestions concerning HVAC equipment being proposed as just received proposal and equipment list.
Manual J information provided by builder
Zone 1 - 1st floor and basement
Total heat loss = 73,278 BTU
Total heat gain = 34,705 BTU
Zone 2 - 2nd floor
Total heat loss = 59,754 BTU
Total heat gain = 32,475 BTU
Zone 1 & 2 specification
Input heating = 80,000 BTUH
Output heating = 78,000 BTUH
Blower motor HP = 3/4
Coil & condenser 3.5 ton capacity 42 MBH
Air volume = 1,400 CFM
HVAC equipment for both Zone 1 & 2 being proposed by builder and HVAC subcontractor
Furnace - Luxaire LP9C080C16MP12C
AC - Luxaire TCJF42S41S3 14.5 SEER
UV light - Field Controls UV-16/120
Air filter - Generalaire MAC2000
Humidifier - Generalaire 900A
Thermostat - Honeywell Focus Pro TH6320WF1005/U
Questions for Pro's
- Any concerns or feedback that I should further inquire to builder, HVAC subcontractor? I did not receive actual Manual J documents but was told HVAC engineer was consulted and that the specifications are the outputs from the Manual J. Did not inquire as to Manual D which I've been reading about now as to duct work.
- For the Luxaire AC, should I be asking for Acclimate series AL6B 16 SEER rather than LX series TCJF 14.5 SEER? Understand additional cost with increased SEER rating, my concern is whether there are greater mechanical improvements, features with AL6B, e.g compressor, fan design, etc.
- For UV light, I would've assumed Luxaire part being proposed rather than Field Controls. Should I have any concerns about this? Also should I ask for 2 UV lights per furnace to be installed or ask for different Field Control model? I see on the Field Control web page different UV light models being offered and not clear what the differences are.
- Thermostat wise should I be asking for Honeywell Prestige or Vision Pro thermostat instead of Focus Pro model being proposed? Or are the Prestige, Vision Pro thermostats not quite comaptible or fully functioning with the Luxaire, Generalaire equipment being proposed? I understand from reading online that Luxaire Acclimate furnace modulates itself rather than being driven by thermostat. Hence should I ask for Luxaire Acclimate thermostat instead?
Appreciate help and thanks in advance.
