Community-led, grassroots initiative to negotiate bulk discounts on heat pump installations.

Hyperlocal benchmarks feat. 20+ contractors. Deep quality research & vetting. We're neighbors in Boston & beyond sharing quotes to get the best deal possible for efficient heating upgrades. Join us & save thousands.


What's a heat pump/mini-split?

These reversible air conditioners cool your home in the summer, and heat your home in the winter - all from the same device. Widespread in Asia and Europe, heat pumps are quickly gaining traction in the US. They both work with and without central air ducts.

If you replace your heating with heat pumps, Mass Save will give you a $10k rebate.

In the MA market, Mitsubishi is typically considered the premium standard for cold climate heat pumps, followed by Fujitsu and Daikin. LG, Gree, and EcoER constitute the mid-market tier.

How do you vet contractors & ensure high quality?

When we strike a bulk deal, we only do it after vetting at least 5 references, all online reviews, and company size & history. I also try to personally visit the contractor's facility for a walkthrough (we did this with Forge).

  1. We start with the 100 closest contractors to the benchmark address from Mass Save's Heat Pump Installer Network dataset.
  2. We filter out ~75 contractors right off the bat based on quality (or lack of info). We typically exclude smaller (<5) shops unless they have good reviews, or Mitsubishi Diamond Contractor status.
  3. We obtain quotes from about 25 remaining contractors.
  4. We personally negotiate & vet references for the 3 best installers. They're willing to give us a lower price in exchange for our bulk volume.
  5. We strike a deal with the best offer.

With our pre-negotiated rate, buyers regularly save 20% to 30% off market average, translating to thousands of dollars in savings.

Which contractor do you have a deal with?

We've been doing R&D for the past two months, which involves doing limited batches of installations (between 5 to 15 households) per month, so there is no big campaign right now.

However, we are assisting with a multifamily bulk deal in May. So, if you're interested in volunteering for an R&D installation at a great price (think: seeing the doctor at an academic hospital like MGH), sign up & we'll let you know whenever there's an opportunity.

In the past, we've worked with N.E.T.R, Elephant, and Forge. You can read more about that in the next question.

What deals have you done previously?

We've run 2 bulk deals so far: Fall 2023, and Spring 2024.

In the Fall, we primarily worked with N.E.T.R. to facilitate ~21 installations at about a 15% discount to market.

In the Spring, we primarily worked with Forge (installation) via. Elephant Energy (sales, scoping, payments) to facilitate 26 installations at about a 25% discount to market.

Collectively, these two campaigns routed about $1.3 million worth of market volume to contractors who we know offer solid installations at a great negotiated price.

Does everyone get a $10k rebate?

If you live in a triple decker, or a single family home: yes. Everyone who completes a whole home installation qualifies for $10k in MassSave rebates, and an additional $2k in the form of a tax credit from the Inflation Reduction Act. The MassSave rebate currently takes a few months to process, and there's a 0% loan that can cover the upfront cost as you wait for that rebate to come through.

The contractor we have a deal with right now, Elephant Energy, has the ability to take that $10k off your upfront cost & handle the paperwork.

Our intake form will tell you if you qualify for $16k (or more) enhanced incentives if you fall under these income ranges.

If you live in a multifamily building: you'd qualify for a partial rebate. While this isn't as much as the $10k, it's still typically a few thousand per unit. If this is you, fill out the intake form & we'll talk.

Who's running this?

Kit Wu. He lives next to Central Square in Cambridge, MA. He started this because he thought it was ridiculous that nobody knew the prices of heat pump installations, and that we needed to make prices transparent and affordable for energy efficient heating to really go mainstream.

Before doing this, Kit worked at Commonwealth Fusion Systems, lived in New York, and did battery research at Harvard's SEAS.

Hannan Rhodes. A heat pump enthusiast with firsthand installation experience, he's worked extensively in solar and is testing new ways to gauge contractor & equipment quality. He's looking to make installations even more affordable.

Laminar is backed by a Mass Save Community Education Grant, and we're building new partnerships all the time.
