Join hosts Matt Bruner and Adam Mufich as they welcome HVAC experts Ed Kaiser and Jim Fultz to a livestream to discuss Heat Pump COP and Low Temp Lock Out - specifically coefficient of performance (COP), low temperature operation, and controls.
Topics covered:
Defining COP and explaining why it's an important metric for heat pump efficiency
Analyzing performance data to compare heat pump output versus electric resistance heat
Discussing reasons why heat pumps seem to underperform in very cold weather
Explaining concepts like balance point and auxiliary heat
Providing recommendations for properly setting up controls to maintain heat pump operation down to lower outdoor temperatures
Sharing tips on airflow and ductwork design considerations for heat pump retrofits
With decades of combined field experience, Ed, Jim, Matt, and Adam offer practical insights into getting the most out of heat pump systems. Tune in to expand your HVAC knowledge!

Very interesting talk 👍🏻
That ending was awkward as frig.
I have saw multiple times where people installed the evap before the furnace and in all those cases, it was a disaster. I condemned a furnace a few weeks back and it was 6 years old and it was a corroded mess. We didn’t install it originally. We replaced the furnace and reused the evaporator and installed it correctly with the coil downstream of the furnace.
I have had two heat pumps installed in my home over 15 years. Both times they were wired to use more electric strip heat than necessary.
Any chance you could share the slide deck or charts alone? Service area Ottawa??
That was an awesome discussion. I've always wondered about systems capabilities in comparison, like Ed created with his graphs. Definitely never considered the amount of wattage needed for heat pump performance vs resistant heat. This was awesome.
I learn so much from you guy’s videos. I for sure appreciate these videos.
Seems like Honeywell was not given much love considering they could handle 4 stages of heat with PI control 20 years ago. With no glitches or power issues. Just worked. Honeywell’s 20 year old Visionpro IAQ could do 4 stages of heat in a heat pump system with plenty of configurable options. It could also do dual fuel or geo. Ten years ago their Prestige IAQ upped the ante with realtime delta t calculations and alerts if performance was degrading or you wanted to test temperature rise in each stage. With electric strips in test mode it is easy to calculate cfm as well. The Prestige added WiFi and was capable of reheat dehumidification. Granted some of their recent low cost T models (except T10) were not home runs but the newer WiFi Vision Pro and the Prestige IAQ are still available.
