Today’s home buyers, building owners, and managers when buying new construction demand increased comfort and reduced energy cost.  Builders generally respond to this need by installing greater levels of insulation, Low-E windows, and more efficient HVAC systems.  This helps to counter the rising cost of energy.

One area often overlooked is the caulking and sealing of mechanical penetrations and other penetrations and other areas where warm moist air can leak into the house in the summer mode and cold dry air in the winter mode affecting air quality and the comfort level in the house. Infiltration may account for 25%-40% of the heating and cooling portion of the utility bill.

Another major cause of discomfort, mold, and high energy cost issues can be attributed to today’s building trends regarding equipment sizing.  Building designers keep adding more SEER and tonnage but are not taking into account the tighter homes and building structures. 

Advantages of properly sized HVAC equipment:

• Reduced equipment size leading to lower energy bills
• Cost less to install
• Will require smaller duct and often smaller blower motors and less horsepower
• Improve comfort and more even temperatures throughout the house
• Proper air flow
• Helps insure a healthy house and less opportunity for mold growth

Disadvantages of oversized HVAC equipment

• Excessive cycle on/off time leads to reduced compressor and motor life
• Lack of humidity control
• Additional installation cost
• Increased energy cost
• Larger air distribution system
• Greater opportunity for mold growth

The comfort level of the house is directly related to the shell of the building structure.  Spray foam will provide insulation that furnishes maximum comfort and reduced energy cost.  Proper sized HVAC equipment and spray foam insulation will reduce energy costs by at least 40%.  For an estimate and to get your questions answered please call Zech at Foam-Guys.com today at 888-423-6264 or e-mail us at info@foam-guys.com.
