The single most common mistake in heat pump installation is treating it as a like-for-like swap for whatever was there before. Equipment sized by looking at the old unit’s badge inherits every mistake made the last time — and oversized systems short-cycle, dehumidify poorly and wear out early.
We start with a load calculation on the actual house: square footage, insulation, window area and orientation, and how the place is really used. On the Peninsula that regularly produces a smaller number than the equipment being replaced, which is a good outcome — it means lower installed cost and better comfort.
Then we check the panel, before quoting rather than after. A heat pump is a significant electrical load, and a large share of the housing stock across Redwood City, San Carlos and Belmont is on a service that was never specified for it. Because we do the electrical work too, that check is part of the same conversation instead of a surprise that arrives once the HVAC quote is already signed.
Installation is permitted, and we commission the system properly on completion — airflow measured, refrigerant charge verified, controls configured. A correctly specified heat pump that was never commissioned still underperforms.
Quoted after a load calculation and a panel capacity check. No quote before both.
Common questions
- Does a heat pump actually work in Bay Area winters?
- Yes, comfortably. Modern cold-climate heat pumps hold their rated output far below anything the Peninsula or South Bay sees. Our winters are close to an ideal case for the technology — the efficiency argument is stronger here than almost anywhere in the country.
- Will my electrical panel handle it?
- That's the question that decides the project, and it's why we check before quoting. Many older homes here run 100A panels already carrying a modern kitchen. Sometimes there's room, sometimes load management solves it, sometimes you need a service upgrade. Guessing at this is how projects stall halfway.
- Can I keep my existing ducts?
- Often, but they need assessing rather than assuming. Ducts sized for a gas furnace move air at a different temperature than a heat pump does, and leaky or undersized runs will make a correctly sized system feel wrong. Ductless is a good answer for additions and rooms the ducts never served properly.
- Is it really more efficient than my furnace?
- A heat pump moves heat rather than making it, so it delivers several units of heat per unit of energy consumed. The comparison against gas depends on your rates, but the efficiency difference against electric resistance heat is not close.
