Heat pumps in Maryland
Maryland sits at 19.7% of homes on a heat pump and has one of the better-funded efficiency programmes in the country behind it. The state spans tidewater and Appalachian climates, but Baltimore's 30°F average low in the coldest month is comfortably inside any modern unit's range.
Heat pump adoption
EIA RECS 2020 microdata ↗19.7% of Maryland homes use a heat pump as their main heat
Goal: every home
Central heat pumps and ductless mini-splits combined, counted as the home's main heating equipment. A further 1% of Maryland homes run a mini-split as secondary heat alongside natural gas.

Money and next steps
What Maryland pays toward one
EmPOWER Maryland
The statewide efficiency programme, delivered through the utilities and coordinated by the Maryland Energy Administration. Heat pump rebates, income-qualified programmes and low-interest financing.
Program details →Federal Home Energy Rebates
The IRA rebate programs (HEAR and HOMES) survived the 2025 tax changes — they were grants to states, not tax credits. Each state runs its own, and they are at different stages: some open, some already out of money, some yet to launch. Check where Maryland stands before you count on it.

The federal 25C tax credit — 30% back, up to $2,000 on a heat pump — ended for systems placed in service after 31 December 2025. If you had one installed in 2025 or earlier you can still claim it; there is no successor credit. Incentives move fast, so check DSIRE for what is current in Maryland. Last checked September 2026.

The numbers
What a heat pump here has to cover
30°F
Coldest month average low
Baltimore · NOAA 1991–2020 normals
90°F
Warmest month average high
Baltimore · NOAA 1991–2020 normals
Both loads matter here — cold snaps are real, and so are the summers. A system sized only for heating will short-cycle in August; one sized only for cooling will lean on backup heat in January. Getting the balance right is the job.
