As an insulation contractor, Combustion Safety Testing is not required. However, it is important to be trained for any case scenario. This testing is usually done by your HVAC company and is only done in homes with natural gas once a year or if you suspect any gas leaks. We are certified in CAZ testing, but this is not something that we include in our services unless specified.

The comfort of your home relies heavily on how well your home’s building envelope is air-sealed.  With the training and knowledge from the Blower Door &Pressure Diagnostic course, our crew can perform a before and after blower door diagnostic to test how well your home is air-sealed and provide you with solutions on how to make your home more airtight and energy-efficient. Blower door testing is now required in all new construction homes; however, any home is a candidate for testing. If your home energy bills seem high and you don’t know why, performing a blower door test could be beneficial.

Energy-efficient home performance is becoming more popular with homeowners and buyers.

Understanding the relationship between the building envelope, heating, A/C, insulation, mechanical ventilation, lighting, appliances, and other systems in your home will enable us to assist our customers in making their homes more energy-efficient. With these improvements, your home’s energy efficiency is the first step towards solar, geothermal, or other renewable energy improvements.
