Want to free up our Heating and A/C closet

I have no storage in our home anywhere.

The home offices have a small closet, the lavatory has a vanity and there is a single hallway closet. In an ideal world the hallway closet would be where I would hang coats, have boots and hold cleaning supplies. Unfortunately what it holds now is our indoor air handler with the Heating and A/C and the water heater. They both take up so much space that I can only mount a broom, wedge a basket and a mop in there. What a waste of space. I have to put a shoe rack in our entryway that looks awful. I also need to keep our Winter time gear in our home office, but cleaning supplies are just all over the locale. I have started brainstorming how to open up that closet. I have decided that when the water gas furnace dies, I am doing a tankless model, but you still have a unit, but it is wall mounted and much smaller. For Heating and A/C I am going to do a ductless option. Inside will be wall mounted indoor air handlers in every room with a thermostat. That way I can have zone control and not provide Heating and A/C to unused rooms. I also free up more than 50% of the closet space. After those two changes I will have plenty of space to store some things. I have diagnosed the ages on our equipment. It looks appreciate our Heating and A/C is 16 years old, so it will go anday now. Sadly our water gas furnace is only 4 years seasoned and will be in there for awhile, but getting a portion of the closet would just be nice at this point.
