How to prepare for a heat wave

As temperatures continue to set new records each year since the climate crisis, heat waves occur more frequently and last longer, causing impacts around the world ranging from uncomfortable discomfort to serious health risks and even death. Making changes to your home to prepare for a heatwave and help keep it cool can be as simple as replacing an AC filter all the way to upgrading a roof.

Here are some ways to prepare your home that can make handling heat waves more comfortable and safer for you and your family.

Clean / replace AC filter

One of the most common problems in AC currents is poor airflow due to a clogged AC filter due to dust buildup. Routine cleaning and replacement of your AC filter is important because in addition to keeping the cool air in your home, it also helps the air quality to stay at a comfortable and safe level. Even if there are no heat waves on the horizon, you should clean your air filter at least once a month and replace it every three months.

Cover all air leaks

To keep your AC power efficient and keep the cool air in your home from escaping, seal any air leaks around the house. Be sure to check the openings in the window air conditioner, as it tends to be common for air leaks. To fix this water strip window, and while you are at the weatherstrip or caulk all other windows as well. Apart from just windows, you stretch all the doors leading to the outside without forgetting the bottom of the door. Another common feature that many do not realize is leaking cold air to the outside is the kitchen air hood.

Consider replacing or fixing rusty pipes

The plumbing system in your home can be severely affected by hot weather. According to Ryan Thompson from PlumbingInformer, “During hot weather, the pipes in your home can expand and even burst in worse cases. The last thing you want in a heat wave is a problem where you do not get any cold water due to broken and faulty pipes or low water pressure. Warm weather also leads to increased water use and changes in the soil that cause tensions on household systems. Replacing and fixing old rusty pipes in advance can save a headache on the road and keep cold water running in your home. “

Add window coverings

When sunlight is directed directly at your home, you should add window coverings to reduce the heat that radiates from the sunlight that causes your home to heat up. Install shades or blinds so that your home feels cool and to prevent heating from the heat. Cell screens do a good job of providing insulation against the heat from sunlight. The windows where the sun shines in their direction should have their curtains closed to better handle the heat.

Make changes to your roof

Changing your roof is not exactly easy, but if you live in an area where you get several heat waves each year, it is well worth the cost to add a “cool roof”. According to Manuel Soto, owner of a Milwaukee Roofing Company, “A cool roof in simple conditions reflects sunlight away from the roof, which means that it absorbs less heat than a normal roof would do. In addition to keeping the house cool, cool roofs reduce AC bills due to less AC usage and lower your roof temperature which helps the roof last longer. ”

Fill in important necessities


There is a good chance that you will spend more time indoors if it is dangerously hot outside, which means that you will consume more water and food. If you know that a heat wave is on its way, you will report this on your next trip to the grocery store. Since everyone will have similar thoughts consider doing this in advance. Be sure to refill plenty of water, food and other healthy drinks that replace electrolytes lost due to sweating.

Other materials you want in your home are box fans. Instead of using them to keep you cool, use them to move hot air out of your home. “One place you want boxing fans to definitely be is the attic. The wind tends to collect hot air, especially during heat waves, which can lead to mold and can also cause roof damage, ”mentions Manuel.

Preparing yourself and your home to handle a heat wave takes time and knowledge. By taking the necessary steps to deal with heat waves, it can keep you and your family comfortable and safe.
