Why is Indoor Air Quality Important? It’s common knowledge that a well-sealed and insulated home can be great for your wallet with lower utility bills. However, this could cause comfort issues when the same air cycles repeatedly through your home. It can also cause humidity imbalances and make your home susceptible to damage from mold. The good news is that it’s possible to have an energy-efficient home that is also comfortable. O'Brien Heating & Air Conditioning in the Main Line can help! Introduce a constant flow of fresh air. To make your home as comfortable as possible and to reduce health-threatening pollutants, your home needs a uninterrupted flow of fresh air. Opening a window isn’t always realistic and can bring pollen and other allergens into your home. Installing a whole-home ventilation system is a better solution. It mixes fresh outside air with your conditioned indoor air. Keep humidity under control. For optimal comfort and health, we advise keeping your home’s relative humidity levels between 30% and 60%. A thermostat with humidity control can help. Here are some symptoms that might suggest your home is too humid: Consistently damp areas Musty odors Condensation stains on the ceiling Condensation or frost on windows Sticky or clammy feeling in the air Peeling wallpaper You have to operate your air conditioner more often to stay cool and dry Whenever the air in your home is overly dry, you can also have problems. In the winter months, indoor relative humidity can plummet into single digits—surprisingly close to that of the world’s most parched deserts.
