Not Too Big, Not Too Small: New Tools for Improved Air Source Heat Pump Selection

Last winter, staff from NEEP’s Heating Electrification Initiative and staff from NYSERDA’s Clean Heating and Cooling teams realized we shared similar ideas about how we could enable better practices related to sizing and selecting air source heat pumps. With NYSERDA’s direct support, NEEP began working to realize these visions.

The (Possible) Evolution of the Window AC Unit 

Mittens, where are my mittens - I’m freezing!

That might be a familiar refrain during winter months in New England, but this time, it was Memorial Day weekend! I woke up at my parents’ house in New Hampshire to a cool 43 degrees – on May 29! Thankfully, they have air source heat pumps that are keeping the house warm, and I soon forgot about my mittens and focused on a hot cup of tea.

Easing Concerns about Refrigerant Flammability

Refrigerant is the lifeblood of an HVAC system, absorbing and releasing heat to keep our homes and buildings cool in the summer and warm in the winter. This “juice” that runs through the refrigeration cycle comes in many chemical forms, each with particular safety considerations. Throughout history, scientists have chased safer refrigerants.

Testing the Resilience of Contractors in the Age of COVID-19

We’ve all been reeling from the effects of COVID-19. Since March of 2020, our personal and professional lives have been altered in ways both big and small. It’s no different within certain sectors of the economy. Nowhere is this more true than the energy efficiency industry. And within the energy efficiency industry, HVAC contractors may be bearing perhaps the greatest brunt of burdens from COVID-19; they’ve been struggling to get through the pandemic since original restrictions were imposed.

Stories from Costa Rica: Scaling up Heat Pumps in the Northeast and beyond

My vacation to Costa Rica last week was a brilliant reminder of two things. One, Costa Rica is very hot, even in February. And two, air source heat pumps are incredibly effective at what they’re designed to do. Truly, the difference between being indoors versus outdoors during the Costa Rican dry season was night and day. The Airbnb my partner and I rented in Tamarindo, a little beach town on the northwestern coast, was equipped with two state-of-the-art heat pump units that kept us comfortable all hours of the day.
