bryant evolution

Are Bryant systems with Evolution controls worth the extra money? The system I am considering is a 13 SEER ( and extra 800bucks for heat pump) condensing unit w/80% AFUE variable speed furnace.

If you are in a steamy climate where extra dehumidification capability is desired, yes! In many parts of the country with today's gas prices, an add-on heat pump to a gas furnace is a good investment too.

Ditto

Depending on your Electric Provider, If their rate, is under 10c a kw your good to go

Either way it's Good equipment,

and the Evolution control is Sooooooooo far out in front of the other mfg's it will take years for them to catch up ,

much like r410a or Puron which Carrier developed and started using in 1995,

it took 6 years for the other manufactures to develop a system to even come close.

Would i need to have a 2 stage furnace w/variable speed blower to take advantage of the Evolution controls system? I currently have an estimate with Evolution control and 2 stage variable speed furnace and another quote with thermidistat control and standard furnace (heat pumps are the same). Both systems are Bryant and there is a huge difference in price. If a variable speed fan is required I might ask the low bidder to add variable speed 2 stage and see what his price is then.

One more thing? does the evolution require a certain evap. coil? the estimate w/Evolution did not mention a model no. for the evap coil.

I am not sure exactly how much extra the Evolution control is (I assume around 1K) but if a 2 stage variable speed furnace is required I know that adds around 700 and I am wondering if it is truly worth the extra $.

thanks

Think I found the answer to one of the questions, according to Bryant website (I think) it said that you had to have a variable speed blower.

I would say go with the Evolution/variable speed furnace. It will cost more will be very flexible and should be quieter in operation most of the time.

The two stage variable speed furnace is required for compatibility with the Evolution control. The Evolution doesn't require a different or special coil relative to what you'd get otherwise.

Either way, make sure that you are getting a thermostatic expansion valve (TXV). Depending on your application, this will either be part of the coil, or attached to the coil by the installer. This is likely already included in the quote, but make sure before you sign on the dotted line.

How do I know if my system has a TXV?
