still have the issue of the old vents, and also heating. The house is actually an older build (60's) and amazingly done to accommodate the environs. Not only proper insulation, but oriented correctly for the sun, window placement also factors in summer baking + blast shield shutters for radiant heat, so I think we might be ok.
We had a splitty in the old place, and ran it at a minimum of ~24c during summer anyway so we're not looking for arctic conditions. Guess it's gonna come down to quote prices - if too outrageous we might put a split in the bedroom and then kick the can down the road a bit.
EDIT: should add, rooms already have reversible fans for pushing air about
Our house has evap upstairs, which does the job in general (plus a fan function) for bedrooms. Got a split in the living room which cools pretty much all of downstairs.
I'd love to have heating through the floor (or hydronic) but we make do.
single level here (albeit elevated) probs with the living room is that it has no easy access to an out door area for the other half (it's kinda centralised to a wraparound hallway with the bedrooms / dining off the hall). Nearest wall is north facing so noooooooooooooooope, definitely want the outside unit on the southern wall in the dank dark alleyway
Don't they have different vent sizes for air conditioning than just heating? Also if it's ancient the ducts are probably in bad condidion and would need to be replaced anyway.
The ducts are actually in amazing shape - they're proper metal ones, and have been well insulated. Someone went through not too long ago and did some work. The unit itself is still serviceable, but we want to get rid of the gas anyway. There's plenty of access - there's a damned house-wide basement down there - and if bigger air delivery is needed we know that's a probability. Weighing the pros and cons of retrofitting vs installing ceiling which would then run into my personal nightmare of wayyyy too many peopel I know who've had monkeys fuck their joists ramming aircon through the ceiling after the fact, plus then we would need to decomission and patch all the existing floor vents....
