Ok, will scratch getting one of those then. Guess long runs of piping thru the roof will be the solution then since the side of the house I want aircon on would need scaffolding because of BS OSH stuff.

well that is what I was thinking with our install; but the dude said "no problem, we have done harder installs". We have approx a 3 story drop to a sloping hill, so I am going to be well interested to see how they run the pipework where i want it. :)

I agree with most of the previous comments.

Too hot? Get aircon.

Too much moisture on the windows in winter? The simplest solution is double glazing. Unfortunately it's the most expensive to retrofit.

I designed and built my own ventilation system and it worked quite well...in summertime. In winter forget it.

Pretty much all the claims put out by these ventilation system companies are just overhyped facts bordering on lies

... and double glazing tends to be ugly - specially if aluminum window frames are retrofitted into old wooden character homes.

If you have an ugly old character home then the glazing is the least of your ugly worries.

well we are almost a week down now after having the ducted system put in and wow what a difference. I know that the temp of the days has dropped considerably since originally having the issue, but even when our son's room jumps up to 31 deg (like it did yesterday afternoon), we just pop the system on and the temp just comes down like a dream! Even on low fan speed the unit is pushing a real decent amount of air into the room; you get chilled ankles standing outside the door with the rush of air coming out from under it :P

good to know! and thanks for the idea. our installation date is set to early April. at leas the winter would be easy...

yeah yesterday was pretty hot. by night time the baby room was still like 28+

I do wonder how much difference a ceiling fan alone would make, most of them in hardware stores are ugly though.

It sounds like our houses are suffering from the identical issues. We had the 3 room system installed (just because it made sense to service all the rooms upstairs rather than just one/two), but seeing as the spare room isn't used and we don't need cooling in our room, we have just set the vents so that pretty much everything (for now) is going into our son's room...as a result the temp comes down real nice and quick; so we just are not worrying now about the heat...more $$ than we wanted to sink but rekon it is going to be a great solution in both winter and summer!

The ceiling fan would move air around which would aid in the cooling sensation for an individual in the sense that it will assist with the evaporation side of things (ie air moving past/over the skin with perspiration)...but if you are wanting to actually change the temp of the air, then I can't see the fan making any difference.
Plus like you mention - ugly :(

Dynamic: I would get a quote for a heat pump to assist your decision.

They dry the air as they work

During summer. They dry the air when in cooling mode, not in heating. In winter, when you want this feature most because the windows are all shut, then they don't do this; and if they do they achieve it by putting the unit into cooling for a period, and then paying to reheat the temp back up.

To the original poster, if it's 30 degrees outside, then a simple ventilation system will take that and pump it into your house. Most houses are not 'stuffy' during summer as everything is as open as you can get it.

If you want to lower the temperature, then get a heat pump.

If you want to blow hot air around, then get a large fan. It will cost around ~$100 or less, and do the same as a $3,000 ventilation system in the room during summer.
