When a heat wave strikes, climate control instantly becomes a top priority for many. But, if your home doesn’t have central air conditioning it can be hard to figure out the best way to cool things down.</br></br>Luckily, there are quite a few different options to choose from.</br></br><strong>The Simplified Science</strong></br></br>Before selecting the right cooling device for your home, it can help to understand a bit about how they work.</br></br>Most function by lowering air temperature with the process of evaporative cooling. When water evaporates it uses energy to change from a liquid to a gas, and to get that energy it essentially sucks the heat out of its environment.</br></br>This is the same process that your body uses to cool itself with sweat, but instead of chilling your skin, cooling devices will change the temperature of the air around you.</br></br><strong>Home Cooling Options </strong></br></br><span style="text-decoration: underline;">Air Conditioners</span></br></br>The classic air conditioning unit works with the same sort of <a title="How Stuff Works" href="http://home.howstuffworks.com/ac1.htm" target="_blank">refrigeration technique</a> your household fridge does, using a contained refrigerant liquid for the evaporative process instead of water. An AC unit can be an easy and effective solution for homes of just about every size, and come in both window-mounted and portable models.</br></br>When picking one for your home, be sure to select a unit with the right BTU output for your space.</br></br><span style="text-decoration: underline;">Evaporative Coolers</span></br></br>Sometimes referred to as swamp coolers, evaporative coolers <a title="How Stuff Works" href="http://home.howstuffworks.com/home-improvement/heating-and-cooling/swamp-cooler1.htm" target="_blank">work by blowing air over water-soaked pads</a> inside the unit. This greatly speeds up evaporation, resulting in a cool breeze that comes out of the cooler. These can be very effective in dry environments, but won’t work as well in humid areas, as the air is more saturated with water that causes the evaporative process to take much longer.</br></br>The cooling capacity of an evaporative cooler is measured in CMF (Cubic Feet per Minute), rather than BTUs like air conditioners; however, most also list cooling capacity in square feet to make it easier to calculate.</br></br><span style="text-decoration: underline;">Dehumidifiers</span></br></br>While dehumidifiers don’t actually bring the temperature down, they can <a title="How Stuff Works" href="http://science.howstuffworks.com/dictionary/meteorological-terms/question651.htm" target="_blank">make a room feel much cooler</a>.</br></br>Coming back to the science again – your body can't effectively cool itself if you're sweating in a room that's too humid to allow it to evaporate quickly. Removing excess humidity from the air lets your natural cooling system work better, so a less humid room feels cooler even if the thermometer stays the same.</br></br><span style="text-decoration: underline;">Fans</span></br></br>Fans are the simplest and often the most budget-friendly options for home cooling. They help circulate air in your space to redistribute heat and also provide a nice cooling breeze.</br></br>Depending on how permanent or mobile you want your fan to be, you can choose between ceiling-mounted and portable fans. If you opt for a ceiling fan, be sure that you have it <a title="Ceiling Fan Direction Explained " href="https://www.atgstores.com/articles/ceiling-fan-direction-explained_a2090.html" target="_blank">spinning the right direction</a> so that it properly cools your room.</br></br>If the breeze offered by a fan isn’t quite enough to keep you cool, you may also want to consider a misting fan. These can be a great solution for cooling outdoor areas or sunrooms as well.</br></br>Whatever option you choose, any of these are sure to help you keep your home more comfortable this summer. And, nothing says summertime like being able to relax in comfort.
