So, while AHR is buzzing about what’s next, we’re proud to #humblebrag a bit—we’re already there. And we’re excited to see the industry move in a direction that benefits homeowners, businesses, and the climate. The shift is here—and it’s just getting started.

At Harvest, we’ve been ahead of the curve. Our systems have always used SANCO2—an ultra-efficient air-to-water heat pump that utilizes CO2, the lowest global warming potential refrigerant available. Harvest delivers heating, cooling, and hot water with a system that’s built for the future.

HVAC manufacturers now have a chance to expand their portfolios to include innovative, sustainable solutions. Air-to-water allows homeowners to store heat efficiently, shift energy use to off-peak hours, and tap into renewable energy when it’s most abundant.

Instead of circulating refrigerant throughout the home, monobloc heat pumps keep it sealed safely in the outdoor unit. This setup not only simplifies installation and maintenance but also opens the door to using more climate-friendly refrigerants like propane (R290).

For years, air-to-air heat pumps have relied on synthetic refrigerants—many of which come with high global warming potential or safety concerns. But this year at AHR, it’s clear that momentum is building toward a more sustainable approach, namely using water as a heat transfer medium.

AHR Expo is where the future of HVAC takes shape, and this year, one trend was impossible to ignore: a shift toward using water to transfer thermal energy into and from the home rather than refrigerants.

In a single-family home? Harvest’s your best bet. But whatever your setup, there’s a heat pump made to fit. Focus on comfort, efficiency, and cost—because no one should freeze under a pile of blankets.

And for those of us in the Golden State…
In SoCal, go for an air-source heat pump with strong cooling and high SEER. In NorCal, try a cold-climate or dual-fuel system. Wherever you are, Harvest delivers year-round comfort without fossil fuels.

For the Beachfront Bungalow
Salt air is rough on HVAC systems. The SANCO2 air-to-water heat pump Harvest uses is corrosion-resistant and built for coastal life. It keeps things comfy even when the ocean breeze turns into a chill.

For the Sprawling Farmhouse
In chilly places like Maine, geothermal might be best. But modern air-source heat pumps, like Harvest, work well in most climates. Cozy, efficient, and low-bill living? Yes, please—even in snowy spots like Norway.

For the Suburban Single-Family Home
For most suburban homes, Harvest is a win. It ties into ducts or radiant heat, delivers heating and hot water, and slashes energy costs by 30%. Plus, it works with smart thermostats—because who doesn’t love a little tech?

For the Urban Apartment
City living means small spaces and shared walls—with no HVAC control. Portable and window-mounted heat pumps like Gradient offer flexible, renter-friendly comfort. Bonus: You can take it with you when you move.

A log cabin in the woods is every hiker’s fantasy, but keeping it warm in winter can be challenging. A cold-climate heat pump is the MVP. They’re built to handle freezing temperatures without breaking a sweat. They'll keep your cabin warm with tech that pulls heat from the coldest air.

Condos are all about efficiency. Enter the ductless mini-split heat pump. They’re widely available, easy to install, and perfect for buildings w/o central ductwork. But if your condo has ducts, you could have a central Harvest system that optimizes your home for comfort, cost, and emissions.
