As much as half of the energy used in your home goes to heating and cooling. Your home's heating, ventilating, and air conditioning (HVAC) system can have a big effect on your utility bills along with your comfort. Take these steps to increase the efficiency of your heating and cooling system:

  • If your HVAC equipment is more than 10 years old or not keeping your house comfortable, have it evaluated by Weatherization Services LLC.
  • If it is not performing efficiently or needs upgrading, consider replacing it with a unit that has earned the ENERGY STAR.
  • Replacing your old heating and cooling equipment with ENERGY STAR qualified equipment can cut your annual energy bill by nearly $200.
  • Before you invest in a new HVAC system, make sure that you have addressed the big air leaks in your house and the duct system. Sometimes, these are the real sources of problems rather than your HVAC equipment.



When creating an energy-efficient, airtight home through air sealing techniques, it's very important to consider ventilation. Unless properly ventilated, an airtight home can seal in indoor air pollutants. Ventilation also helps control moisture—another important consideration for a healthy, energy-efficient home.

Your home needs ventilation—the exchange of indoor air with outdoor air—to reduce indoor pollutants, moisture, and odors. Contaminants such as formaldehyde, volatile organic compounds, and radon can accumulate in poorly ventilated homes, causing health problems. Excess moisture in a home can generate high humidity levels. High humidity levels can lead to mold growth and structural damage to your home.
