Atmosphere is everything.

Harvest is on the clock 24/7, working hard to make sure your home’s air and water temperatures are juuuuuuuust right. 

Better than a normal heat pump system. 
Waaaaaaay better than a gas furnace.

Harvest isn’t hype.
It’s science.

Wait, what’s going on here?

The Heat Pump

Our hyper-efficient heat pump harvests electricity when it’s cheapest and cleanest (see what we did there?). It pulls warmth out of the air, even when it’s cold out.

The Tank

A very-insulated water tank holds just the right amount of heat until you need it - as hot water, or as warmth for your home. Temperatures inside the tank are continuously monitored and controlled. Easier said than done.

The Pod

The Pod tells everything else in the system what to do, and when to do it. All based on real-time data - temperature, rates, emissions…and if friends are staying over, the Pod adjusts for more showers on the fly.

The Air Handler

Hot water safely runs to hydronic coils inside the air handler. A super-efficient fan blows air across the hot coils and, ta-da!, your home is warmed. As are you.

The Air Handler works in homes with forced air. But if you use radiant floors, we’ve got you covered too.

A four step process

(More or less)
01

We chat

Spill the tea on your home: how big, what’s your current HVAC setup, and what you want out of your new Harvest system.

02

We quote

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.

03

We install

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.

04

We done

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.

More cool things

Yup, we also do A/C

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.

Filtered air, everywhere

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.

Night cooling. For free.

When it’s nice out, Harvest can bring cool, filtered air in – even when the windows are shut. An extra layer of optimization that feels a little bit like magic.

Energy bills your great-great-great-grandkids will be proud of.

Load Shifting

We harvest clean, cheap solar energy around noon and store it as heat in the water tank. People shower and heat their homes in the morning and the evening when the grid is dirtier and more expensive. With Harvest you can use heat and hot water whenever you want, using that clean, cheap energy stored up in your tank.

Harvest Electric Draw (kW)
Electric Grid Emissions (KG CO₂e / hr)
Regular heat pump electric draw (kW)
Emission-slashing
Harvest cuts emissions from home heating ninety percent compared to gas furnaces, and forty percent compared to heat pumps without storage. Since home heating and hot water are around 2/3 of home energy use, this is a really big deal. We’ll put it this way: Harvest cuts more emissions than switching from a gas car to an EV.

Bill-shrinking

These are energy bill reductions for fifteen real homes that replaced gas with Harvest. It’s easy to see why Harvest pays for itself in as little as five years.
