In this episode of the HVAC Know It All Podcast, host Gary McCreadie chats again with Drew Tozer,  author of Feel Good Homes and Partner at Foundry Heat Pumps, and Expert Advisor at Building Decarbonization Alliance and Jouleia. They talk about why right-sizing HVAC systems is so important and how old rules of thumb often lead to discomfort. Drew explains how load calculations, better filters, and smart installs can improve comfort, air quality, and energy use. They also touch on heat pump myths, hybrid systems, and why teaching both homeowners and techs can lead to better results and fewer system issues.

Drew Tozer talks about why many homes feel uncomfortable, drafty rooms, poor airflow, and wrong system sizes. He explains that heat pumps, when chosen and installed right, fix these issues and help save energy. Drew also highlights how indoor air quality is often ignored and why better filters should be standard, not upgrades. Gary shares stories of past installs that prove doing the math and using load calcs lead to better results. They agree that homeowners and techs both need clear info to make smarter choices and keep systems running well for years.

Drew explains that many homes stay cold or drafty because the HVAC system isn’t sized or installed correctly. Like putting on the right shoes, using load calcs helps pick the best heat pump for comfort. He says square footage isn’t enough; you need to know how the house works. Gary shares how better filters, return drops, and smart installs stop airflow issues and dirt build-up. They both say systems should be sized with care, not guesswork, so homes stay comfy, air stays clean, and systems last longer without costly breakdowns.
