Hoping to solicit some advice from the pros here... We currently have a Carrier Infinity 96% efficiency furnace, variable speed blower, 2 stage gas valve, 80k btu furnace with the Infinity controller. The AC portion was an existing install, Kenmore 14SEEER. The compressor is making a very loud 'bang' every time it kicks off and we've had several techs from different companies give us bids to fix it. All bids have been what I consider to be too much in comparison to investing in a new system.
In any case, we are looking at the Carrier Infinity and Bryant Evolution communicating series of AC and heat pumps. I do know I'd like at least a dual stage compressor for comfort, but beyond that I don't know what to do. The sales guys are all trying to sell the highest seer available (obviously) and are pushing the heat pump as a good option saying that they'll both save us a ton of money. I'm not so sure and the information out there on money savings with a higher seer rating is mostly sales literature.
In AC, we are looking at the 24ANB6, 24ANB7, and 24ANB1 in a 3 ton with 3.5 ton coil. Manual J calculations have been performed by 2 of the bidders with the same results.
In heat pump, looking at the 25HNB6, 25HNB9, and 25VNA0 in a 3 ton with 3.5 ton coil.
Can anyone advise if there is any financial benefit to going with the higher SEER/EER rated units? I'd love to lower our utility bills but the higher units are significantly more expensive.
Live in Utah, where summers are hot 90-100*, winter is cold 10-40*, and spring and summer can be mild or any combination thereof. Rates for our power are as follows:
Rates for the gas as follows:
1st 45dec 6.95/dec
1st 45dec 7.91/dec
Thanks for any help or advice you can give!
