"Still Hot Even With Your A/C Blasting?
Sweating? Can't Sleep While Your A/C
Keeps Burning Your Hard-Earned Cash?"

Who else wants to be rescued from brutal summer heat? Your attic will never
ever get up to 150 degrees again, so the rooms below your attic will be cooler.

burning $100 bills in your barbecue" -Jet Fan Man

The truth is that attic fans are effective and practical in reducing your upstairs temperatures in rooms and helping to cut cooling costs. I installed another Jet Fan attic fan in June of 2009 and stopped to check some temperatures with my new toy, a Fluke brand thermal imager and I was taking temperature readings everywhere. The temperature outside in the Chicago area was 86 degrees F. with no clouds.  The wind was light and coming from variable directions; a typical summer day for Chicago. The roof temperature at 2 PM was 154 degrees F. The roof had standard mushroom type aluminum vents installed, not a ridge vent. Inside the attic the underside of the sheathing was 147 degrees F. and the top of the insulation was 134 degrees F. The air temperature in the attic by a mercury thermometer was 139 degrees F. The top of the drywall ceiling was 97 degrees even under 12 inches of insulation. The 6 inch batt insulation had a vapor barrier at the bottom and 6 inches of insulation blown in over the top. The temperature of the bottom of the drywall ceiling (the finished ceiling) was 92 degrees. Think about that, you are trying to keep it below 80 using air conditioning while the most massive surface in your upstairs, the ceiling, is radiating heat at 92 degrees. Bringing the temperature of the drywall ceiling down from 97 degrees at the top to 92 degrees at the bottom represents wasted energy as your air conditioning has to cool the ceiling as heat penetrates. What if you could lower that ceiling temperature from above? Well, you can and you can do so very efficiently with a fan. Fans are very simple and do not require a condenser and evaporator like your air conditioning system and do not suffer from inefficiencies related to all that machinery. A fan simply uses cooler outside air to replace the mostly trapped super-hot attic air. And the good thing about our Jet Fan attic fan from www.JetFanUSA.com is that our fan moves more air per watt than any other electric attic fan. Yesterday our fan started removing 139 degree air as soon as I hooked it up. On some of our hottest days it would be removing 150 degree air and of course those are the days when you can really tell the difference in upstairs cooling from previous years on similar days. Once the fan is installed it will start running when the attic temperature reaches 100 degrees in the attic and keep running all day until after the sun goes down and the attic temperature comes down to set temperature, usually 90 degrees. With an attic fan the attic air temperature is usually not more than 10 degrees warmer than outside. Attic fans can make close to a 50 degree difference in attic air temperature and depending on your electric rates our Jet Fan attic fan from www.JetFanUSA.com will only cost you around 25 cents even if it has to run 12 hours during the hotter days.
The lie about attic fans is that they suck air out of your house. How? How can they do that? Unless your ceiling has huge gapping holes in it air cannot pass through drywall. Most homes have air conditioning, and the attic air is substantially separated from the house air. In very rare circumstances, there may be gaps allowing house air to flow into the attic. These gaps may be in the form of missing access doors or whole house fan shutters that are missing or broken or just plain holes in the ceiling or walls that separate rooms from attic space. Walls and ceilings should be somewhat airtight and insulated whether you have an attic fan installed or not. Your room’s walls and ceilings should not have holes and should be insulated and the attic access doors and ceiling scuttle panels should be somewhat airtight. Otherwise during winter, heat and humidity from the house can rise up into the cold attic spaces. You will not only lose heat but the heat and humidity flowing into the attic will create dampness and frost on the wood framing of the house and eventually cause mold and rot. Also, during summer your air conditioned house air could escape or be sucked into the attic by the attic fan if there are holes in your ceiling or walls or missing access panels. These are unusual circumstances which should be corrected for the attic fan to help you cool your rooms efficiently. Minor leaks through light fixtures or wall outlets will not impact your cooling bill and could provide a little exhaust of stale air by making room for a little fresh air from outside like a bathroom fan or fresh air exchanger is intended to do. Of course any such leakage can and should be minimized by keeping your homes doors, windows and chimney flues closed while using air-conditioning. For houses that do not have enough venting to the outside from the attic; the addition of more attic vents to the outside will minimize overall suction in the attic and thereby minimize drawing air from the rooms and maximize airflow from outside through your attic, right where you need it.
The secret about attic fans is that they are not all the same. Jet Fan at JetFanUSA.com has an attic fan that will last longer than your 50 year roof and a motor that will last up to three times longer than other attic fan motors, it takes half the power to run, and is much quieter. Be sure you navigate to www.JetFanUSA.com because other companies are using our URL in their advertising. They are hoping you don’t notice. So don’t be fooled by cheap imitations.
