Why now · Connecticut

Gas bills have climbed every year.

Connecticut gas climbed from ~$1.25/therm in 2010 to $1.85/therm by 2025, on top of the highest residential electric rates in the contiguous US. A heat pump locks you off the fossil-fuel ride entirely, while delivering 2.5× the heat per unit of input.

06 · Questions Homeowners Ask

The honest FAQ.

Actual questions that come up in the first installer conversation, answered for a typical Connecticut homeowner in 2026.

Why does CT electricity cost so much?

Combination of imported generation costs, distribution infrastructure, and public policy program charges. Silver lining: high rates make efficiency upgrades pay back faster than almost anywhere else in the country.

What's the Smart-E Loan?

CT's equivalent to the MA HEAT Loan, below-market efficiency financing. Not 0% like MA (2.49-4.99% APR), but terms up to 12 years make it accessible for larger projects. Administered through participating CT lenders.

Every Connecticut program a homeowner can layer in. The badge marks the ones that pair most naturally with the program on this page.

CT · Residential Renewable Energy Solutions (RRES)
Solar offsets the heat pump's electric load with clean kWh from your own roof. Sized together, the array carries the heating bill.
Stacks well
CT · Connecticut Insulation
Insulate first, then heat pump. A tighter envelope means a smaller, cheaper heat pump that runs more efficiently.
Stacks well
CT · Connecticut Windows & Doors
Old windows can defeat the heat pump's gains. Upgrading them together protects the comfort the new system delivers.
CT · Energy Storage Solutions (ESS)
A battery keeps the heat pump running through outages, especially important when fossil backup is gone.
