Heat Pump-Air Handler question
I have a 12 year old Bryant Heat Pump, 10 Seer, 3.5 ton. The reversing valve is crap. Right now I am running the heat in Emergency mode (electric furnace) until I fix it.
Ive been on www.ingramsairandwater.com and located a 13 SEER 3.5 ton Goodman unit with matching air handler. My question: is it reasonable to go with same 3.5 ton system I had before without going to all the trouble to do a load calc on the house if I am getting the air handler with the variable speed fan? Wouldn't the variable fan speed settings allow me to program the desirable cfm moving through the house.
Thanks for any advice
