What it is
HVAC contractor article explaining heat pump installation costs ranging $6K-$15K, with electrical infrastructure as a key variable. Older homes frequently require panel upgrades or new wiring to support electric heat pump loads. Improper wiring during installation leads to heat pump failure-to-start issues.
Why it matters
Electrical contractors and MEP teams bidding building electrification retrofits face scope uncertainty when existing service and panel capacity is unknown. The article identifies electrical upgrades as both a cost adder and a failure mode (wiring errors preventing startup), affecting estimating accuracy and installation sequencing in older housing stock.
Evidence from source:
- Older homes may require panel upgrades or new wiring to support electric heat pump heating systems, increasing installation costs
- Heat pump not turning on due to wiring errors listed as a specific failure mode from improper installation
- Installation cost range $6,000 to $15,000 with electrical upgrades as a named cost variable

Open questions
- What panel amperage thresholds typically trigger service upgrades for heat pump retrofits in single-family vs. MDU applications?
- Are there specific wiring error patterns (breaker sizing, wire gauge, disconnect placement) that drive the ‘heat pump not turning on’ failure mode?
