Insulation & Heat Energy

In the winter, heat flows from your heated living space to the cold outdoors (or garages and attics). Heat energy can move through ceilings, walls and floors. In the summer, the reverse happens, and heat energy makes its way from outside, to inside your home.

Insulation is about slowing down the heat conduction/convection process. Insulation resists heat flow, and is rated with an “R-value”. The higher the R-value, the more efficient the insulation. There are many types of insulation materials including fiber materials, foam and cellulose.

Blown Insulation

Blown insulation is a popular method, especially in existing construction. As a certified energy auditor, we can perform testing on your home to indicate where insulation may be needed. If there are any walls that require insulation, blown insulation is a non-destructive way to meat the need. Contact Stewart’s Heating & Air Conditioning to learn more about blown insulation, or a home energy assessment today!

Home Energy Audit

Home Energy Audit

If you’re new to the idea of testing your home for energy efficiency, you’ve come to the right place! As a Walnut Creek certified energy auditor, we have the tools and expertise to give you an accurate assessment of the energy efficiency of your home. This will determine what areas can be improved, along with estimates on annual utility savings.

Thermographic Scans

Thermographic Scans

As a Walnut Creek certified energy auditor, we use sophisticated tools to assess the energy efficiency of your home. One such tool is a thermographic scan using infrared cameras. Thermography reads heat levels, which we then use to detect energy leaks in your home. These can be caused by air leaks or areas with a lack of insulation. Thermographic scans are often used with a blower door test.
