When HVAC contractors expand into home performance, they often experience a steep learning curve as they discover the new tools they need to add to their fleet. One tool considered an absolute necessity is the blower door, and manufacturers have recently rolled out new technology designed to make this equipment easier to learn and operate.
Among the challenges faced by contractors as they learn to use blower doors is a simple recognition of its limitations, according to Frank Spevak, marketing and sales manager, The Energy Conservatory (TEC). “I believe that the biggest challenge to the contractor is understanding what a blower door test can and cannot do, and how the information from the test will help them to develop an improvement plan for the house,” he said.
