How to Make a House Less Hot

What is the Fastest Way to Cool a House?

If you walk into your home and it feels like an oven, you’re probably wondering how to cool it down. The answer? Get the hot air out and the cool air in, fast!

Portable air conditioning units are one of the most effective quick-fix solutions. Simply put, they pull in warm air, cool it using internal coils and refrigerant, and then vent the heat outside via an exhaust hose. What’s left is cool, dry air that circulates your room; no permanent installation required.

These units are great for renters, temporary setups in guest rooms, or just for extra help on those extra-hot days. Add a fan into the mix to spread the cool air further, and you have a recipe for instant comfort.

How to Cool a House in Hot Weather

A single AC unit might not be enough if facing a full-blown heatwave. You’ll need to approach it strategically. First, stop the heat from getting in. Keep curtains or blinds closed during the hottest part of the day, especially on south- and west-facing windows. Blackout curtains or reflective thermal blinds can make a noticeable difference.

Next, ventilate properly in the early morning or evening when outside temperatures dip, and open windows at opposite sides of your home to create a cross-breeze. Pair that with a fan pointing out of one window (to pull heat out) and another drawing cool air in, and you’ll have a DIY ventilation system that works wonders.

If using a portable air conditioner, ensure warm air isn’t leaking through the window gap. That’s where a window seal kit becomes essential; not only does it improve your AC’s performance, but it also helps reduce energy costs.

How Can I Cool Down My Room Without AC?

Not everyone wants (or needs) a full air conditioning unit; in some spaces, it just isn’t practical. If you’re wondering how to keep your house cool in summer without cranking up the AC, there are still plenty of effective options.

Which Direction Should a Ceiling Fan Go in the Summer?

It might seem small, but setting your ceiling fan in the correct direction can make a big difference in how cool your room feels.

In summer, set your fan to spin counterclockwise. Doing this pushes cool air down and creates a gentle breeze that helps lower your body temperature, creating  a ‘wind chill effect.’ It doesn’t reduce the room temperature but makes it feel cooler, which is the next best thing.

Bonus tip: Turn off fans when you leave the room. Unlike AC, fans cool people, not air, so there’s no point running them in empty spaces.

Will a Portable AC Cool a Bedroom?

Short answer? Yes. Bedrooms are one of the best spaces to use a portable air conditioner, especially if you don’t have central AC or want to avoid cooling the entire house unnecessarily.

A unit like the Challenge 9000 BTU is ideal for most standard bedrooms. Look for one with sleep mode or programmable timers so it runs quietly and efficiently overnight.

You can boost performance even more by combining it with a fan. The AC unit cools the air, and the fan distributes it evenly across the room.
