Preparing Your Electrical Panel for Home Heat Pump Conversion
Evaluating 100A vs 200A main service panels, dedicated circuit requirements, and outdoor disconnect switches for electrification.
Transitioning from gas heating to an all-electric heat pump system or adding ductless mini-splits requires an electrical load assessment by a licensed electrician.
Older homes with 100-amp electrical panels may require a 200-amp service upgrade to support 30A to 50A double-pole breakers for outdoor heat pump compressors and indoor air handlers.
Modern smart electrical subpanels and energy management switches can automatically shed non-essential loads, avoiding costly utility transformer drop upgrades in some municipalities.
Always ensure an weatherproof fused disconnect switch is installed within sight of outdoor heat pump condensing units per NEC Article 440 safety guidelines.
