How Plum prices
Transparent pricing, the way it should be.
No call-center markups, no commission pitch, no guess-the-price games. Here's exactly how we price a job — and the honest factors that move your number up or down.
The owner quotes it — in person
Sam comes to your home and prices the job himself. You never get a commission salesperson.
Flat & upfront
You get one clear number before any work starts. The price we quote is the price you pay.
No surprise upsells
We recommend what your home actually needs — not what pads a ticket. Anything new, you approve first.
Financing with Wisetack
Financing up to $25,000 with interest-free options — a soft credit check that won't affect your score, and a decision in seconds.
What actually affects your price
Every home is different, so we don't post fake sticker prices. Pick a service to see the real things that shape the number — then Sam gives you an exact, honest quote in person.
Heat Pump
All-electric heating + cooling in one system — the Peninsula's electrification workhorse.
Typical Peninsula installed range
- Ducted central heat pump$12,000–$25,000+
Whole-home comfort using or upgrading existing ductwork.
Typical Peninsula installed range, before rebates or financing — not a Plum quote. Your exact number comes from Sam in person, in writing.
What shapes your number
- How many square feet you're heating and cooling (this sets the system size).
- Whether your existing ductwork can be reused, sealed, or needs replacing.
- Your electrical panel capacity — most Peninsula homes don't need an upgrade.
- The Mitsubishi equipment line and efficiency (SEER2 / HSPF2) you choose.
- Permits, Title 24 paperwork, and inspection — handled for you.
Across the whole product range: Peninsula HVAC and heat-pump projects span roughly $5,000–$25,000+ installed depending on the system, home, and scope (see the per-service ranges above where we've published them). That's a directional band, not a Plum quote — your real, all-in number comes from Sam in person, in writing.
Honest Price Guarantee
The price we quote is the price you pay.
No surprise upsells, ever. Get a free, no-pressure in-home quote from the owner — or send us a competitor's bid for a free second opinion.
