Summer heat can be a lot of fun, but it also brings with it one major disadvantage: summer humidity. Humidity is unpleasant both in and out, but it’s especially dangerous when combined with a high level of moisture. Mold grows in damp environments very readily. How can you keep your house safe throughout the summer?

Mold is a problem all year round, but it’s worse in the summer. Why? Mold thrives in moist conditions and warmer temperatures. Molds are also more prevalent when there is more rain and humidity. The moisture from rain and humidity can easily get into your roof or walls which creates the perfect environment for mold to grow. Plus, we spend most of our time inside during the summer months so we’re exposed to indoor air quality issues like mold that may not be noticeable during other seasons – especially if you use your A/C often!  In this blog, we’ll discuss why mold is worse in the summer and how it can affect your health.

Why is Mold Worse in the Summer?   

Mold is categorized as a common allergen. According to the American College of Allergy, Asthma and Immunology (ACAAI), mold belongs “to a group of substances that can cause an allergic reaction in individuals who are sensitive to these allergens.” The presence of mold spores may even affect those who aren’t aware they’re allergic, making it harder to diagnose the source of their symptoms. As summer approaches, you should take precautions to ensure your home isn’t a breeding ground for mold. From the pipes under the sink in your bathroom to the little spot above the washing machine, it seems like mold is worse in the summer months.

What You Can Do to Prevent Mold Growth in Summer?

For mold prevention this summer, make the following changes: Keep humidity levels between 40-60%. Mold can grow in as little as 48 to 96 hours. Change your air filters regularly. If you have a forced air system, this should be done every 3 months. Make sure all your home’s leaks are sealed. If you have a crawl space, ensure all vents are covered. Fix any water damage as soon as possible. Keep rooms completely dry after any leak has been repaired. Allowing mold to grow can lead to serious health problems, so it’s important to keep your home clean and prevent the growth of this fungus.

How To Prevent Mold Growth

Don’t run your A/C in high humidity. High humidity levels can cause mold to grow on the evaporator coil, which is a part of the A/C unit. This will result in a musty smell when you’re using your air conditioning system. In order to fix this issue, call an HVAC specialist immediately if you suspect your A/C is making mold grow. Do not use portable swamp coolers in the summer months. Swamp coolers are widely used to lower indoor humidity, but they are known to cause other issues. Please note that you should never attempt to do any maintenance work on your own when it comes to HVAC systems – this includes replacing evaporator coils, clean filters or even inspect for mold growth!
