Principles of Moving Air

As a Refrigeration Tech, Instructor and Contractor I’m often called out to trouble shoot problems with heat pump and A/C air handling systems. In 20+ years of experience I’ve found failure is typically:

• 90% low air flow
• 5% control failure
• 5% refrigeration circuit failure

TECA’s POMA Course has helped me diagnose the key contributors of low air flow. I now can confidently identify and often correct the prime underlying causes: Undersized duct, Air flow restrictive fittings and Undersized and/or Inappropriately placed filters.
