Air Conditioning (Nature's Own & FREE)---Cold Night Air & How To Trap It As Air Conditioning

Are there many locations that experience daytime temps in the 80's, yet they cool down to the low 60's at night in winter? This video shows you where & how to install a 1,600cfm (cubic feet per minute) attic fan in your home's CEILING to draw the cold night air INTO your home. A well insulated house keeps the heat (or cold) out; it also holds the heat from your furnace inside while keeping the cold winter air out. So how do you take advantage of the cold night air & use it as a/c for the next day? Opening a window on a cold night lowers the inside temp 1 degree; running this fan can pull it down another 3 degrees. Running the fan for 2 1/2 hours during the coldest part of the night (04:15-06:45am), will drag the cold air in cooling everything (walls, studs, tile floors, furniture, etc.). Cabinets can be opened to allow the heat locked inside to escape from them, as well. Early risers should check inside & outside temps, ensure that there is no rain & low humidity, and ensure that there is no smoke from any brush fires; once all is checked & satisfactory, you can hit the manual kill switch installed between the fan & the timer. If all conditions are good around midnight/01:00am, the windows & fan door can be opened and ready to go, but the manual kill switch should not be activated until final checks are made at 04:00am. This system works great on single story homes that don't enjoy a two story's "chimney effect". An attic with 250 bird holes under the eaves with a vented ridge cap OR 1, or 2, whirlybird ventilators, works well for this concept. This fan is only used in winter; opening your garage ceiling access to the attic & the side door (with security screen) should be done year round to allow the hot air to escape from your garage. NEVER leave the overhead garage door ajar a couple of inches, unless you want rodents moving into your garage/home! After about an hour of running the fan, I close the window in the guest bedroom that was opened only 2 inches; that creates more suction on the other windows that are open. About 30 minutes later, I close the second bedroom window, which leaves only the kitchen at the front and the master bedroom at the back as sources for the fan to draw from... IF you want to go back to bed, be sure to wear socks, Levi's, a sweater, and hide under a blanket as you pre-cool your house for the new day! A night time temp below 60* will freeze your buns off! The next day your a/c will not activate with your programmable thermostat set at 74* until after noon, often 02:00-03:00pm depending on daytime temp. My first installation had the kill switch at the ceiling access hatch, but I plugged it into a normal timer in the attic; just note that doing the installation in that manner requires that you go up into the attic any/every time there is a power failure to ensure that the fan is commencing/ending during the coolest nighttime temps. The fan is available from Home Depot for around $130.40; nothing listed at Lowe's; Ace Hardware lists a 1450cfm for $99.99. If you want to decrease your "carbon footprint" this set up will do the trick; or it will save you $$$ on your electric bill, or increase your electricity "credits" per month if you have rooftop solar PV for your electricity.
