Let"s face it, as soon as it"s hot and also you don"t have air air conditioning it can be borderline homicidal. What"s worse is as soon as the temperature begins to emboldened outside and also your home feels like an oven. Most of us revolve on a pan to acquire some waiting moving throughout our skin - i beg your pardon is a an excellent idea.

You are watching: How to cool house with fans

But moving hot air around feels pretty futile, doesn"t it?

What if you could replace the waiting in your residence with new, cooler air, quickly and also efficiently? friend can! all you require is a fan and a cooling plan.

When i was a volunteer firefighter we had to change the waiting in people"s houses all the time. We would certainly get referred to as to a home since someone forgot to take the bread native the oven and also the smoke create from the range would start to fill the whole home.

Often time we could fully exchange the wait in a house with one pan in just a few minutes by using positive Pressure Ventilation (PPV) or an adverse Pressure Ventilation (NPV), relying on the situation.

Here"s just how it works.

If a residence is complete of smoke, every one of the home windows would be opened and also a fan would be placed around 6" native the former door ~ above the exterior that the house. The air blowing into the house would increase air pressure and force the smoke out of the rooms.

Conversely, if the smoke to be localized then we would place the fan about 6" indigenous the door top top the within of the house encountering out, thus developing a negative pressure in the house. This would cause air come rush right into the open up windows transparent the house, advertise the smoke out the prior door.

Granted, we offered a pan that had a wood prop you can find ~ above a small aircraft, powered by a 10 speech engine.

Don"t despair! The principals the PPV and also NPV can still job-related for you also if you have actually a continual box pan - it just takes some planning.

Spending every kinds the time and also energy cooling your living room with a fan in the window does naught for the EZ bake Bedroom in ~ the end of the hallway once it"s time to hit the hay. What us really desire to do with that futile fan is placed it to work-related replacing the warm air in the bedroom before bedtime.

Yes, close all the doors and windows. Our goal is come systematically cool the house room through room and also we need to seal off areas that don"t need instant cooling and carry out a solitary place because that cool waiting to go into the house. A crate fan deserve to only do so lot so we desire to it is in as efficient with it as we can. Make the efforts to north the whole house through one box pan is a garbage of time.

Open a door or window at the other finish of the house from the bedroom. We"ll use this as our exit hole to dump warm air native the house.


Place the box fan within the house about 3" to 6" native the window, dealing with outdoors and also turn that up as high together it will go.

The placement of the pan is critical to the success of ours plan. By put the fan near the opening and not *in* the opened we rise the performance of the fan significantly by creating a little of a vortex.

Here"s just how that works. Once air moves conveniently from one place to one more it create a low pressure around the obelisk of fast moving air. To check out this in action, take two strips of paper, host them from the top about 3 inches apart. Punch downward between the 2 strips that paper. You"ll see that the file strips pull together at the bottom that the wait stream. The quick moving wait has produced a short pressure and the waiting on the other sides of the file is trying to move in to fill the low pressure space.

What that method for our fan plan is this. Our fan is pulling double duty because, in enhancement to the air being moved from the house by the fan blades we"re additionally picking up a significant amount the ambient air on the other side the the pan that rushing in to to fill the low press area approximately the obelisk of air comes from the fan.

Pretty cool huh? (pun intended)


Pick a room and cool it.

Now that we"ve acquired a great stream of air leaving the home it"s time come decide wherein we desire the new air to concerned replace it. I pick the bedroom. Ns can resolve a warm living room for an hour, yet I can"t abide a hot bedroom because that 5 hrs of torture before trying to leaving for work.

Open a grand total of 1 windows in the bedroom and prop the door open. You"ll begin to feel a breeze of external air comes in v the window. If all your various other doors and also windows space closed, the quantity of waiting coming with the home window will be similar to the an unified air steam leaving the room at the other end of the house.

I don"t cool the whole house. I stick come cooling the bedrooms and call it good. I just want come sleep well.

Work v the prevailing winds in her area. Don"t allude your exit fan at a door that"s acquired wind blowing in. Use that wind in your favor.

Cooling a two story home have the right to be a bit tricky. You may need come implement a fan arrangement on every level of your home. If it"s impossible, cool the downstairs and also sleep ~ above the couch if you can. It"s only temporary.


Fan placement You know your pan placement is point out on when the stream of air coming from the fan totally fills the opening of the exit home window or door. As soon as I was on the fire department we would ar the fan and put ours hand in ~ each edge of the opening we to be using. You need to feel air motion in all corners of the opening. You might need to put the fan on a table or tilt it earlier to obtain the best coverage.

Fan Stacking

This is one of my favorites. If friend really want to obtain the job done, try placing two fans in series. The very first fan will develop a shaft of waiting blowing into the back of the 2nd fan that"s pointing to your departure opening. Place the very first fan in such a way as come capitalize top top the vortex effect, hence increasing the second fan"s capacity. We would execute this on large houses filled with smoke and it worked amazingly well.

Be Patient

Look, girlfriend don"t have an wait conditioner. This an approach isn"t going to turn your home into a place where you can leave milk on the counter and also come ago the next day and have it it is in cool. We"re talking around exchanging the air within the house for air exterior the house. If it"s hot outside, it"s no going to it is in magically cooler once it passes v your window.

Enjoy the breeze

Once the bedrooms are cool ns leave the pan in place and also open all the bedroom windows. Once you get the majority of the warm air the end it"s pretty to enjoy the little bit that breeze the the fan arrangement affords during the night.

Draw the blinds

Keeping your house cool throughout the work is always a great idea. We"ve always lived in old houses and also this is no tiny task. In enhancement to our fan arrangement we had actually to have a shade arrangement during the day, blocking out sunlight from home windows that challenge south.
