Air Quality

Be aware of your indoor air.

Did you know that your indoor air can be, on average, two to five times — and in some cases up to 100 times worse than outdoor air?

That’s right – and it may surprise you to know that the biggest culprit is typically an improperly maintained heating and cooling system. Why? Because it provides the perfect breeding ground for mold, bacteria, and fungi – harmful growths that can affect your family’s breathing, allergies, and health each and every day.

Pass One Hour can help!
