Energy saving summer HVAC tips: Have you considered a zone system for your home? Zoning can drastically lower your heating costs. With zoning, you no longer have to pay to heat or cool areas of your home that are rarely used. You won’t have to heat or cool the whole house just to make one room comfortable. Zoning divides your home into separate comfort areas, which are heated or cooled based on your needs. Zoning is efficient and flexible enough for any home.
