Upgrade your home with reliable comfort, lower bills, and clean energy — all from a system designed to last for decades. Harvest combines high-efficiency heat pumps with smart thermal storage to give your family year-round comfort, up to 40% utility bill savings, and dramatically lower emissions.
A hyper-efficient (and quiet), air-to-water heat pump “harvests” electricity when it’s cheapest and cleanest, using it to heat up water to store in the thermal battery tank.

A specially-insulated water tank which acts as a thermal battery - efficiently storing heat for later use, reducing peak-time electricity needs and improving energy resilience.

The brain of the system. It continuously optimizes performance, energy use, and cost based on your comfort preferences, grid conditions, and even adjusts to your usage habits.

Delivers consistent heating and cooling throughout the home, with optional air filtration upgrades.
The full system acts as a replacement for your current HVAC and hot water heater.


What do I like best about the system? Wow, there are so many things!

Honestly, we feel kinda spoiled now. Don't know how we can go back to the old system.

Harvest helped us improve our comfort and our energy footprint.

I truly feel I have the ultimate heating/cooling system.

We simply feel better about being in our home knowing every day contributes to the clean energy transition.

[Harvest] exemplifies the benefits of combining underappreciated hardware with smart software.

It’s the most efficient system I was able to find in my research.

Harvest has unlocked the decarbonization potential of heat pumps with its smart thermal battery.

We’re doing a good thing for the environment, and we’re paying about 40% less.
Spill the tea on your home: how big, what’s your current HVAC setup, and what you want out of your new Harvest system.
We’ll work with your local Harvest installer to determine the best system configuration for the needs of your home, and advise on available incentives. They’ll get you the best price for what you need.
It takes just a few days for your installer to set up Harvest, with minimal down-time on comfiness - and we’ll get you a new smart thermostat, if you need it.
Harvest starts optimizing bills, energy use, and comfort the minute you switch it on. Kick back, relax, and wait for your next utility bill to be a lot comfier, too.

Getting hotter where you live? We’re happy to hook you up with air conditioning – or upgrade yours to get you four seasons of comfy-smart.

Wildfires, pollution, pollen…it’s kind of a mess out there. Our whole-home filter gets you high-grade filtration throughout your home - so you can get rid of plug-in units.

When it’s nice out, Harvest can bring cool, filtered air in – even when the windows are shut. Ask your contractor for Night Cooling - an optional layer of optimization that feels a little bit like magic.
