Heat Pump Electrical Planning
Before You Call the HVAC Company
Heat pumps need serious electrical capacity. We check whether your panel can handle it, and plan for the EV charger, water heater, and induction range you'll probably want next.

Every assessment runs on your utility's 15-minute interval data, analyzed under an engineered load calculation (OESC Rule 8-106(8)). Measured demand, not assumptions.
3 Ways a Heat Pump Project Goes Sideways
HVAC First, Electrical Later
Your HVAC contractor picks the heat pump. Then you find out your 200A panel can't support it without a $15,000+ service upgrade. The project stalls for months.
One Upgrade at a Time
Heat pump this year. Next year, EV charger. Then the induction range. Each one triggers panel work, so you pay for rewiring 3 times instead of once.
No Roadmap
You want to electrify, but where do you start? HVAC says call the electrician. The electrician says get the heat pump quote first. Nobody is looking at the whole picture.
Typical Approach vs. The Energable Approach
We build your complete electrification roadmap, accounting for heat pump, EV charging, water heater, cooking, and anything else you're considering, so you only do the electrical work once.
TYPICAL APPROACH
- HVAC contractor picks the equipment
- Electrician figures out how to make it fit
- No consideration for future loads
- Repeat the whole process for every upgrade
THE ENERGABLE APPROACH
- Assess capacity first, so you know what's possible
- Plan all future loads: heat pump, EV, cooking, water
- Right-size the infrastructure so one upgrade handles it all
- Give the HVAC contractor clear specs, so there are no surprises
Your Complete Picture, Not Just the Heat Pump
Heat Pump
30 to 60A typical · heating and cooling
EV Charger
40 to 60A typical · Level 2 charging
Induction Range
40 to 50A typical · replace gas stove
Water Heater
15 to 30A typical · heat pump or electric
Battery Backup
30 to 60A typical · Tesla Powerwall
Heat Pump Dryer
30A typical · replace gas dryer
Pool / Hot Tub
30 to 60A typical · heat pump and equipment
Future Ready
Planned capacity · what's next
The total could easily exceed 300A+ on paper. But with proper load calculations and diversity factors, most 200A services can handle full electrification, if you plan it right from the start.
Why Most Homes Don't Need 400A
Contractors add up nameplate ratings. Engineers calculate what actually runs at the same time.
Contractor math (nameplate)
"You need a 400A service upgrade."
Engineering math (measured usage)
200A service is sufficient. No upgrade required.

Heat Pump Questions
The kind we would give before you commit a dollar of capital. Tap a question.
Do I need to upgrade to 400A service for a heat pump?
Should I get the heat pump quote first, or the electrical assessment?
What if I also want an EV charger and induction range?
How long does the assessment take?
Can you also do the electrical installation work?
