About Dave Hartzell
Dave Hartzell opened Hartzell’s Heat & Air about 15 years ago, bringing 45 years of HVAC experience to central Oklahoma. He holds a Master HVAC License, is NATE Certified, and is an IGSHPA-accredited geothermal installer — one of very few in Oklahoma.
The podcast started because Dave kept noticing the same thing: homeowners were making expensive HVAC decisions based on bad information from contractors who had a financial interest in the wrong answer. The podcast is his attempt to level the playing field.
No sponsors. No affiliate deals. Just 45 years of honest HVAC experience, explained in plain Oklahoma English.
