We install window heat pumps, window ACs, wall-throughs and other room air products across entire buildings — fast, affordable, and without construction.
For all buildings from single family to multi-family to affordable housing and public housing, we manage everything from site assessment and logistics to installation and resident coordination.
Our team is grateful to Lawrence D'Alfonso, a resident of Carroll Towers and Resident Commissioner (appointed by the mayor), who helped us access the building when needed and was a pleasure to coordinate with.
When a heating system fails in a low-income household, there's rarely time to do it right. Emergency replacements lock families into another fossil fuel system — and another decade of high bills and emissions. Envr Air's lending library is a rapid-response service that puts a clean, efficient heat pump in place while a permanent solution is arranged.
Household heating system fails
Program partner identifies income-eligible household
Envr Air installs window heat pump in 24–48 hours
Permanent electrification arranged via Mass Save
Envr Air removes or transfers the unit
Why it works
We've been running rapid-deployment models for 16+ years through RentAnAC. The warehousing, crews, scheduling systems, and track record already exist — the lending library applies that infrastructure to the most urgent gap in the clean energy transition.
We work with a variety of heating and cooling technology products because no single unit fits every situation.
Available right now in our online store. 9,000 BTU cold-climate window heat pump — ideal for single rooms, small apartments, and residential spaces. Purchase yours, and let our team handle the professional installation — on whatever day works best for you.
Not sold residentially — Gradient supplies through institutional partners only. We deploy these on multifamily, public housing, and large-scale projects. The unit installed at Carroll Tower in Providence.
