Retrotec

Retrotec began as a blower door manufacturer in Ottawa, Canada. But, by 1984, they grew to include offices in the US. Retrotec soon expanded their services to include instruction for home performance and whole house diagnostics professionals. Since that time Retrotec has evolved into the world’s leading manufacturer of building diagnostic tools, software and manufacturer’s certification. Retrotec blower doors and duct testers were specifically geared towards for-profit contractors. The target was professionals that build and retrofit high performance houses that don’t qualify for government subsidies. The not-for-profit sector developed overtime into a driving force for technological innovation and grew the expertise of its workforce. Now, Retrotec designs and delivers equipment and applications for testers and researchers in both sectors.
