Spring 2024 Campaign

Spring 2024 Campaign

FYI: we've fully booked out installation capacity in a little more than a month. Thank you everyone who participated! For those who didn't make it in time - sign up on our main page. You'll be the first to know if there's a follow-up to this spring bulk deal.. 

We are extending a partnership with Elephant + Forge that caps install costs at $15,250 for a standard 3 zone mini-split setup. 

Hey Boston! After spending three weeks researching market prices for single family homes out in the suburbs (a blind spot we had last time w/our triple decker condo benchmark), we now have a new deal with Elephant Energy (https://elephantenergy.com/) & Forge (https://www.forgeco.com/).

Forge, out in the field

Anyone can take advantage of this at least until March, and likely till April, and I'm posting the numbers here as a price ceiling because I really don't think you should be paying anything more than what's listed here (with any installer). 

Note: these estimates are valid only for standard, wall-mounted ductless mini-splits, and central air systems. Elephant + Forge can handle other installations, but if you're getting a ceiling cassette requiring carpentry work on the ceiling, it can deviate substantially.

Here's what Elephant is offering for standard installations:





3 head, 2.5 ton

$15,250.00 (↓ $250 vs. fall)


4 head, 3 ton



5 head, 3.5 ton



2 ton ducted

$16,500.00 (↑ $500 vs. fall)


3 ton ducted

$17,500.00 (↓ $1k vs. fall)

4 ton ducted
