Replacing a 100k btu / 80% AFUE NG furnace and 3T A/C with a new heat pump. I've spoken to a number of contractors and received quotes from a couple companies; the contractor whom I am by far most comfortable with sells Bryant and Mitsubishi. They quoted a couple Bryant options; based on our Manual J, I'm thinking a Mitsubishi may be a better fit.
Mitsubishi options I researched:
1. 2T P-series hyper heat (PVA-A24AA7 & PUZ-HA24NHA1) PH-24.pdf
2. 2T M-series hyper heat (SVZ-KP24NA & SUZ-KA24NAHZ) MH-24.pdf
3. 2.5T M-series (SVZ-KP30NA & SUZ-KA30NA2) M-30.pdf
Bryant quotes received:
1. 3T 5-stage Evolution (288BNV036000 / FE4ANF005L00) Bryant 288.pdf
2. 3T 2-stage Preferred (226ANA036000 / FV4CNF005L00) Bryant 226.pdf
It looks like 2T is as big as we can go to maximize the heat output without vastly oversizing the cooling load. I understand the staged Bryant equipment partially alleviates the oversizing issue, but the Mitsubishi seem to be a better fit for our actual loads. We have to add supplemental electric heat with any of the options.
I'll contact the local contractor on Monday. Any pros/cons on the equipment options above, or suggestions on which would appear to be the best fit? Is Mitsubishi equipment vastly more expensive than the Bryant options quoted?
- DESIGN CONDITIONS -
Lincoln NE (Design temps 0F heat / 94F cool), elevation 1188'
Our normal winter temps range around 10F-35F; summertime average temps are closer to 85F, so I had load calcs ran at multiple temps to help with equipment sizing.
Heat Load Calcs:
34,331 @ 0F
26,488 @ 15F
16,146 @ 37F
Latent Cooling Loads:
3,677 @ 94F
4,690 @ 85F (not sure why latent load is higher at 85F, but load calc shows higher infiltration latent load)
Sensible Cooling Loads:
13,663 @ 94F
10,950 @ 85F
