Episode notes
What A Hybrid HVAC Actually Is
- A hybrid HVAC system pairs a furnace with a heat pump so a home can run on either fuel as conditions require.
- The heat pump provides reversible cooling and heating while the furnace supplies high-output backup on very cold days.
Heat Pumps Improve Comfort By Load Matching
- Heat pumps run longer at lower output, matching house heat loss better than oversized furnaces.
- Longer run times warm house surfaces and deliver noticeably better comfort than short furnace blasts.
Swap AC For Heat Pump During Routine Replacements
- Replace an aging air conditioner with a like-for-like heat pump to create a hybrid without touching the furnace.
- That change immediately reduces furnace runtime and provides automatic backup if the heat pump can't meet demand.
