The Best Temperature Settings For Your Home To Prevent Mold

Is your home’s temperature setting appropriate?

Mold can grow in just about any type of climate, but temperature can play a role. Mold can grow in lower temperatures, but in general the higher the temperature the more likely it is for mold to form.

Mold needs moisture and nutrients, both of which can occur in nearly all homes – both new and old.

Your thermostat is crucial in ensuring the optimal functioning of the heating system in your home. Taking control of your thermostat and getting it set correctly can help prevent mold from growing in your home.

Recommended Temperature Settings To Avoid Mold

Your home’s cooling and heating system should offer comfort and convenience to your indoor setting. We’d all like to avoid mold issues, but unfortunately mold and humans typically like similar temperatures.

There is no single right temperature for your home. It varies depending on what the outdoor temperatures are like in your surrounding area. And that obviously varies throughout the year and even through the month, week or day.

The average temperature in Canadian households is approximately 21 degrees. Most common indoor fungi grow at 10-35 degrees. That’s a wider range that most would think. It would be pretty cold in your home if you kept it at 10 and it would be equally uncomfortable at 95 degrees.

It turns out that running a temperature that is too cold during the warm summer months can result in condensation in the home. And the opposite can happen in the winter when you’re heating your home.

Changing temperatures in your home can affect air circulation and humidity in the home. This can lead to issues with mold in the home especially if your home goes from cool temperatures to warm temperatures.

For example, in the summertime it’s common for household surfaces to become cold especially when air conditioners run overnight. When daytime arrives and the air heats up it results in condensation especially on surfaces near the outside of the home or near areas of the home that get warm quickly like those near windows.

This can lead to condensation – the perfect situation for mold growth.

Set your thermostat to match the outdoor temperature as best as possible. And look to make the changes in the temperature slow so air temperatures and surface temperatures remain similar.

Check For Condensation To Prevent Mold

One of the big factors with indoor mold is ventilation. Have your home inspected for ventilation issues. These could relate to the construction of your home or it could also relate to your heating and cooling system.

Look for areas in the home where air can become trapped. A common issue could be lack of ventilation in attics and near roofs. Hot air rises and if it gets trapped it can turn into condensation, which can lead to water and mold issues. But that’s just one potential ventilation issue. Bathrooms and kitchens are other areas to examine.

Also keep an eye out for where condensation forms in your home. On very cold days in winter and on very warm days in summer there can often be condensation as your heating and cooling combat the extreme outdoor conditions.

If you find condensation on extreme days, clean the water as best you can. It may just be a temporary situation due to the extreme conditions. But keep an eye on the situation to see if it becomes a recurring issue. And if you suspect any other areas in the home have condensation even in more normal conditions then it’s worth getting a professional inspection.

Mold grows in a range of temperatures, but the conditions that lead to condensation and moisture are the ones to watch for. Use the tips above to make sure your home is moisture-free and if not take action to prevent potential mold issues.
