I do have an older style Heating system however (hot air) and I was just wondering if anyone on here can either support me with this form of beating or recommend me someone.

Hey BP!
Are there any members in the Osan AB/Camp Humphrey's area interested in meeting up? Let me know if there is interest!

To compensate I am thinking of installing a new gas furnace (instead of all new duct work and forced air & central air as initially planned.

As for rent collection- if you just have a few units, Cozy is great- we used it very effectively up until 20 units or so. 

You can shut off registers, that's why they have the flap on them to control the amount of air coming through each vent. 

Purchased end of sept of 19 and sold march 4 of 20 completed renovations mid to end of December, Full renovation inside and out, added a third full bath downstairs, added central air, removed 2 walls in kitchen for open concept, and made a dedicated laundry room.

Tax is the only thing still up in the air but let's assume the upper end.. $200. 

Upgraded electric, added forced air a/c and ductwork, and new plumbing.

Rainy winter so can’t open windows, but have had air circulating.
