How big is your home?

Why Plum HVAC

The comfort partner your home deserves.

We earn the 5-star reviews the same way every time: by being honest, doing exceptional work, and treating your home like our own.

Honest, up-front pricing

You see the price before we start. No surprise fees, no pressure — just clear options you can trust.

Family owned & local

14+ years serving Silicon Valley neighbors. When you call, you reach real people who know your community.

Diamond-level expertise

As a Mitsubishi Electric Diamond Contractor, our installs meet the highest standard — and carry the best warranties.

Greener by design

We lead with efficient, all-electric systems and help you capture every clean-energy rebate available.

Workmanship guaranteed

2-year labor warranty standard, extendable up to 12 years with a Premium Maintenance Plan — because comfort should last for years, not months.

Clear communication

Photos, plain-language explanations, and a single point of contact from your first call to final walkthrough.

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.
Explore heat pump

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.

“Plum HVAC replaced our old gas furnace with a heat pump and handled every rebate for us. The crew was tidy, on time, and explained everything. Our bills dropped and the house is finally comfortable.”

Maria L.Heat Pump Installation · Palo Alto

“Honest, fair, and genuinely kind. They could have sold me a whole new system but fixed the real problem for a fraction of what I expected. I won't call anyone else in the Valley.”
