First, you need a load calculation and duct design. Zoning makes zero sense for forced air heating or cooling unless your equipment can modulate capacity and airflow. Otherwise, you are still operating the equipment that makes X btu of heat or cooling, but are using x-y and dumping the rest...

The bend offset in the detail view (detail B) is obvious to me. I couldn't make the parts to the same tolerance that you can, but I know that I could make something functionally comparable on the equipment that I have. Looks like a 1/4" bend up 90º on 3 sides. Why do that vs a hem? Stronger...

This is an illustration for the bends required to make a drawer box on a sheet metal brake. Note that a box and pan brake will be required. For a 36" wide x 24" deep drawer with 4" sides, you need a piece of metal that's 44-1/2" x 29". The magenta dashed lines are 180º "up" bends for a hem...

What kind of tools do you have to cut and bend the metal? At a minimum, you will need a jump shear and a box and pan brake. Metal gauge will dictate the equipment. You will not be able to bend up 20 gauge sheet metal on a cheapo brake. You will need crisp bends. What kind of stuff do you have...

Any cheap burglary tools? Too soon? :lol_hitti

The technique is pretty much the same.

Don't leave us hanging on the important details like equipment, scope of work and of course the price... ;)

That would probably derail the project...

Fixed it for you. And until homebuyers are interested in what is beneath the painted drywall, nothing will change.

There is a very significant wholesale price difference between an "old fashioned" single stage compressor and a upper end variable speed variant. Even within a variable speed product line, there is a significant price difference from an "18 SEER" model to a model with extended low temperature...

The heat output from a non inverter system is not the same as a "regular" system. It comes down to equipment specs.

If both of those are inverter compressor systems, they do not work the same as a "regular" system.

Given 36k btu AC, I'm assuming that won't cover heating, even if the heat pump will output full btu's under 17°F.... But, guesswork without numbers.

If it is sized properly and the balance points are known.

There is truth to this. But one still needs to know the balance point. It is possible that a "3 ton" condenser will run out of steam in heating mode. Even a Bosch IDS will only deliver a maximum of 36k btu of heat (for that size unit) down to 3° F. If you need more than 36k btu of heat at say...

There is some truth here. If the system is oversized, or if the ductwork is too small for a properly sized system, a variable speed motor WILL compensate- to a point. Then your operational costs will go up and motor life will go down. Also some truth here. However, nothing is simple any more...

No, it can't be.

They're certainly firing on all 5 cylinders lately.
