Protect the exterior of your home such as walls, ceiling, windows and doors by sealing and insulating cost effectively. Be an informed homeowner or an expert contractor and save up to 20% on heating and cooling costs which is about 10% on total energy bill as per ENERGY STAR.
You can easily feel drafts and air leaks near windows and doors but other hidden areas such as basements, attics and crawlspaces are a nuisance. Improve comfort and save money by sealing air leaks with SPF, caulk or weather stripping. Check out the diagram for better understanding.
Too tight sealing is also not recommended as we do need some fresh air to breathe as per set minimum requirements. If in doubt, hire a Home Energy Rater, who can measure your home’s actual leakage with his diagnostic tools and if found too tight, a recommendation for fresh air ventilation may be recommended.
After any home sealing project, have a heating and cooling technician check to make sure that your combustion appliances (gas- or oil-fired furnace, water heater, and dryer) are venting properly. For additional information on Indoor Air Quality (IAQ) issues related to homes, such as combustion safety, visit EPA’s Indoor Air Quality Web site.
R-value is the measurement for insulation capacity and various insulation materials have their own use in different spaces such as attics, crawlspaces, basements and walls. To get the best insulation it is very important to seal all air leaks to prevent any transfer or movement of air.
Maximize your savings by adding extra insulation to the attic and crawlspace. You can determine the need for more insulation by checking the bare attic floor. The recommended insulation level for attics is about R-38 which is equal to about 12-15 inches. R-49 is preferred for freezing winters.
Ducts are lifelines that distribute conditioned air throughout the house with forced cooling and air-heating systems. However there is a 20% chance for air loss due to faulty sealing and leaks when moving through the ducts. So don’t be surprised when you get shocking utility bills no matter how many times you have checked your thermostat setting.
Make sure you follow ENERGY STAR quality installation guidelines when replacing your forced cooling and heating equipment. Get a thorough inspection of your duct system, sealing and balancing of the ductwork so that you can ensure comfort and optimal performance of your new system.
