Envr Air installs heating and cooling solutions across entire buildings — quickly, affordably, and without disrupting residents. No construction. No electrical upgrades.
A logistics model 16 years in the making — applied to the most urgent gap in the clean energy transition.
We install through existing windows and plug into standard outlets — quick, simple, and tenant-friendly. Most installs take about 30 minutes, with residents staying right where they are throughout.
We've converted 194-unit high-rises in 12 days. That's a logistics advantage built over 16 years — warehousing, scheduling systems, and crews capable of 200+ daily installations.
One unit replaces both the heating system and the window AC. Residents get individual temperature control — often for the first time. If a unit ever fails, it's swapped out in hours.
From housing authorities to clean energy funders, we partner with organizations leading the transition across the Mid-Atlantic and Northeast.
Carroll Tower in Providence, RI — 277 heat pumps installed across a fully occupied affordable housing high-rise. Decades of electric baseboard heat replaced with cold-climate window heat pumps. No construction. No electrical upgrades. No displaced residents.
