IHO - how much was your AC bill this summer? The highest we got was about $245. Don’t do it man. Solar is not ready for prime time.

After six years, my savings exceed my after tax cost of the system.

You the taxpayer however, still taking it in the shorts.

As a taxpayer I’m used to taking it in the shorts, nothing new there. It’s about to get worse too if trumps tax plan gets rid of the state tax deduction.

Well I'm west of the 5 but I've had a whole house fan for several years. Best investment I've ever made, hands down.  ;) Since we had it installed we only run our air conditioner a few days per year.

They installed a grate in the ceiling above the second floor hallway which connects to the actual fan through a flexible duct; this helps keep the noise and vibration to a minimum. We also had some additional venting installed in the roof, because all that air needs a way to flow freely out of the attic otherwise the system is useless. The total area of your vents has to match the CFM rating of your new fan in order for the system to work well. We went with "O'Hagin" style vents; they are low profile and not visible from the street. The fan itself is by Comfort Cool. All told it was around $3000.

HTH :D

@qwertaxpayer:

Yeah hit the high $200s a few times this summer. Want to go double PHEV/EV eventually so may need to harness the sun.

Wow almost 5 years later and I have not done either.

Going to start looking at whole house fans again... would do solar... esp with mutliple EVs but that money is earmarked for other stuff right now.

It’s fantastic. I am amazed how efficient it works  especially getting cold air inside the house in the evening. My new fresco home comes with 2 Quiet Cool systems (one in master bedroom and 1 in hallway). Last couple of days, when it gets little warm toward end of the day, i only need to turn on 1 system and the 2nd floor cools down after 15 min.

Do you use some kind of filter on the open window? The only drawback I have read is the amount of dust/pollen that may come in the house if use extensively.

I was looking at installing one myself, it's not overly complicated and they have models with wireless remotes.

My wife is concerned with the dust, especially when construction is still going on next door and we haven't done the backyard landscaping yet. Not to mention PS is a bit more remote.

Weird... I hear the opposite as it removes indoor dust and pollution from the home.

What kind of cost am I looking at for QuietCools installed? I used to think it was less than $1k but now it looks like $5k?

If you don't filter the air you will bring in dust and pollen to various degree while also pushing out dust and pollutants.

One additional advantage is that you cool your attic with a whole house fan which can give a bit more thermal inertia during the day to avoid the house to warm as fast.
