Feedback for new construction HVAC proposal
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 calcs. Would appreciate feedback, suggestions concerning HVAC equipment being proposed.
Manual J calc output
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 BTU
Output heating = 78,000 BTU
Blower motor HP = 3/4
Coil & condenser 3.5 ton capacity 42 MBH
Air volume = 1,400 CFM
HVAC equipment proposed for both Zone 1 & 2
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
- Any concerns, missing information as to specs and HVAC equipment being provided? I did not receive actual Manual J raw #s input / used but final output #s from the HVAC engineer that was consulted.
- 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, e.g compressor, fan design, etc. that should be considered with Acclimate series
- For UV light, I would've assumed Luxaire being proposed rather than Field Controls. Should I have any concerns about this? Also recommended to have 2 UV lights rather than 1 UV light per furnace?
- Thermostat wise should I be asking for Honeywell Prestige thermostat instead of Focus Pro? Or request Luxaire Acclimate thermostat instead?
Appreciate help and thanks in advance.
