    Which Goodman unit will suffice
    We live in Orange County, California (mild climate) and need a new gas furnace, with 80% efficiency. Our old one is probably 70-80% (has igniter, metal duct) Will we need larger cold air supply when we switch? Is there a model that comes on quieter and then goes to higher blower setting? Our present Carrier is too noisy.

    The variable speed model is a bit quieter BUT after the warranty is over the motor and controls if proven defective cost big $$$$. Go for the 95+ percent unit.

    Comment on hvac1000's post
    Thank you for the tip, hvac1000; is the 95% better because its motor and controlsare better? Generally, will the new furnace require larger cold air return; our present one is 192 sq. in.of room air and a larger opening in the subfloor.

Goodman 2 1/2 ton unit [ 8 Answers ]

My Landlady just bought a new goodman outside unit. It worked for about a week then cut off. The Installer said it could have been anything and needs a new compressor. She has spent about as much as she did for the upstairs unit (a payne) that works fine after 12 yrs of operation. What's the deal...
