Hey Anons,

Wondering if there are any HVAC /air flow autists willing to weigh in and/or provide links to expert DIY sites:
Here's the scenario if you're still reading:
-
Central Air unit has to be replaced (36 years old)
-
Home is 1600 square feet –the part that needs AC (attached 3-bay garage and shop are another 1600 feet, but AC not needed there, kek)
*House is set on wooded land – VERY humid in summers
-
Have also wondered about installing a whole house fan or two not only to cool house down in summer, but to generate more air flow through the attic (attic has plywood floors and high ceilings which extend over garage and shop areas – a whole studio apartment could be added up there w/plenty of space to spare.)
-
Maybe add a window or two in attic? very stuffy
*Prevailing wind direction is west to east; front of house faces southeast
-
Have eeked AC unit along last few summers – added a booster to the compressor summer 2018
*Something in the relay switch went this past summer; handy family member gerry rigged it so we could set it manually w/ screwdriver
-
Cannot get freon in our state anymore
-
Have been told not only do we need to replace the unit, but the ductwork as well b/c something something new non-freon lines won't work with current duct work (?!?)
*Was given a "ballpark" price of $7-8K (Ouch, not happening.)
*Handy family member is primarily a carpenter but can pretty much fix/install/repair anything – BUT said family member
is not very good at researching on the Internet.
Basically, would like to spend no more than $3K; maybe $4K if we're also doing the whole-house fans/windows in attic.
Would appreciate any serious feedback from knowledgeable anons. Sorry to interrupt, but ya'll are the smartest people I know. I was close to hitting all 7's tonight; maybe I'll get lucky yet.
