HVAC Know It All Podcast

In this episode of HVAC Know It All, host Gary McCreadie talks with Chris Howells, Senior Training & Development Manager at AprilAire, about designing smaller filters and cabinets while maintaining filtration performance and airflow. In Part 2 of their conversation, they discuss three-inch media, one-inch MERV 11 filters, and installation practices that affect pressure drop. HVAC technicians will learn why filter depth alone does not determine performance and how transitions help systems use the filter's full face opening.

Howells describes more than four years of development work informed by contractor, distributor, and consumer feedback. He explains how AprilAire's engineering and product management teams addressed shrinking mechanical spaces through changes to media construction and cabinet design. He also shares field-testing experience that connects those design choices to airflow concerns and maintenance schedules.

• How smaller mechanical rooms and contractor feedback are driving thinner filter cabinets and changes to their dimensions.

• How supporting mesh, electrostatic media, and adjustments to metal backing help three-inch filters retain surface area while limiting pressure drop.

• The role of increased surface area and frame design in AprilAire's one-inch MERV 11 filter offering.

• Why filter service intervals and field validation matter when matching filtration options to maintenance agreements.

• How transitions that expose the full filter face help avoid pressure increases caused by undersized return openings.

In this episode of HVAC Know It All, host Gary McCreadie talks with Chris Howells, Senior Training & Development Manager at AprilAire, about applying indoor air quality solutions during shoulder seasons and making filtration part of a complete HVAC approach. They cover humidity concerns, filter selection, MERV ratings, pressure drop, airflow, and ways technicians can explain system performance to homeowners.

Chris draws on his work educating contractors about filtration and indoor air quality. He explains why increasingly sealed homes and modern variable-speed equipment require technicians to assess the full system, including duct design, filter surface area, and delivered airflow, before recommending higher-efficiency filtration.

• How to use shoulder-season humidity and comfort concerns to start an ethical indoor air quality conversation.

• Why indoor air quality solutions should address human health and comfort rather than focus on selling products.

• The relationship between filter MERV rating, pressure drop, surface area, and delivered airflow.

• How deeper media filters can provide more filtration surface area without equating filter depth with restriction.

• Why variable-speed ECM motors can be more affected by restrictive filters than older single-stage PSC motors.

• How static-pressure measurements and visual evidence can help homeowners understand filtration-related system issues.

In this episode of HVAC Know It All, host Gary McCreadie speaks with HVACR Educator Don Gillis of Gillis Coach about how HVAC training has changed from the field-based approaches of decades past. They examine apprenticeship experiences, knowledge gaps, digital learning tools, and how senior technicians can build confidence by involving apprentices in real troubleshooting.

Drawing on more than 30 years in HVAC, including roles with Emerson, Chemours, and as a service manager, Don shares how he developed his training approach. His experience teaching refrigerants, building science, weatherization, and technicians in the field informs his focus on practical learning, curiosity, and helping people advance in their careers.

• How involving apprentices in setup and troubleshooting can build confidence instead of treating them only as helpers.

• Why a senior technician should ask an apprentice for input when a diagnostic process stalls.

• The value of teaching a repeatable troubleshooting methodology so apprentices can identify missed steps.

• How digital resources can help apprentices find answers when the technician beside them does not know the answer.

• Why withholding knowledge can weaken training and limit a team's ability to solve problems.

• The importance of creating a respectful truck environment where apprentices can learn without unnecessary frustration.
