Home efficiency in Hartford.
Hartford winters are exactly what modern cold-climate heat pumps were built for — the biggest heating bills in Connecticut come from old oil, propane, and electric-resistance heat, and that's exactly the waste an efficient system eliminates. Pair the upgrade with air sealing and insulation, and homes here feel warmer while costing meaningfully less to run.
