Ducted Microwave

Anyone had a range hood with ducts through the ceiling added where there was no duct or hood before? The above the stove microwave has a built in circulating ductless fan with carbon filters but it's really useless. We'd obviously have to remove the microwave and go to a countertop model.

Suggestions for who does this kind of work and recent cost? Not looking for a kitchen remodel just a ducted hood over the stove. I am assuming it can be ducted straight up to and through the roof assuming there is no roof supports in the way or any building code against that. No access to outside wall just UP. It's the "usual" stove with above stove mounted microwave configuration.

Our above the range microwave is ducted to the outside and it is mounted to an interior wall. So, it CAN be done (with enough money!)

Find a microwave with a good vent fan. Don't waste counter space.
Remember that all exhaust must exit the house - not into attic space.
High CFM also emphasizes need for replacement air that has to come in, from outside somewhere. Would the least path of resistance be other fans' ducts? Or around windows and doors. What temperature is that air going to be?

ED, after rereading, the thread, here is what I would do:

1. Contact home warranty and ask them who does this work for new installs.
2. Call this contractor to see if they can work with you to install a new duct.
3. Discuss with above contractor about taking duct from kitchen, 45-degree angle to guest bathroom, and 45-degree angle to ceiling, then straight up to roof.
4. As noted above if the first contractor cannot cut the hole in the roof and properly seal the penetration, have a roofer ready to do this work.
This approach will keep the kitchen clean and will not impact the existing cabinets, and should have minimal impact on the guest bathroom.
The exhaust fan port on the microwaves appear to be centered and a standard size, also the typical UNDER CABINET range hoods seem to share the same location for the fan port. This approach allows for the removal of the microwave and the replacement with a hood at minimal cost. One work of caution, if you get the backsplash tiled (or similar) then you will have an unfinished area when the microwave is removed.
Hope this helps with your project.
