Heat pump vs. furnace in Maryland by electric utility

What to know about the Maryland numbers

• Rebates not checked yet. We haven't checked heat pump rebates in Maryland yet, so the numbers here leave them out. Utility and state programs can take thousands off a heat pump, so ask your utility and your contractor what's available.
• Mostly average prices. Only 27% of Maryland ZIP codes here are priced on a current utility tariff. The rest use the utility's average price from the U.S. Energy Information Administration, which is about two years old and doesn't show tiers, so the winter price of extra kWh is estimated. Enter the rate from a recent bill for a closer answer.
• Supplier choice. Many Maryland households buy their electricity supply from a competitive supplier. We use the utility's standard price; if you buy from a supplier, enter your total price per kWh from your bill.
• Time-of-use rates. 2 utilities' tariffs here charge different prices by time of day. We assume heating and cooling use is spread evenly across the day, which can be off if most of yours falls in peak hours.
