Sounds expensive for sure, James.

But as you and we all know....your HVAC system is something worth investing in, especially for those of us in the sunbelt!

I'm one of those who have the Goodman unit for the outside condenser unit. Will be 6 years old in September. The air handler is much older. Probably 15 years now. When the Goodman goes, it will probably be time to re-do the whole system and upgrade to the new refrigerant.

I've been trying to extend the life of the Goodman as much as possible. Hosing down the coil, keeping cold galv spray on the filter to stave off rust, and I also have a small 6K BTU window unit I have been running lately to cut down on how much the Goodman has to run.

I also re-roofed with aluminum in silver color earlier this year so that helps with the sun's rays. This winter I plan to re-insulate the attic and then at some point start with window replacement.

Like Bill, am also interested in learning more about project. Thanks!
