Oil-to-Gas Conversions Are Reshaping How Wilmington Heats Its Homes
February in Forty Acres. Oil delivery truck pulls up to a house that burns through 800 gallons a winter. The furnace is 22 years old. Next door, the neighbor converted to gas last summer and cut their heating bill by a third.
Wilmington has one of the highest concentrations of oil-heated homes in Delaware. Cool Spring, Forty Acres, and Bayard Square are converting to gas and heat pump systems as oil prices stay volatile and rebate programs make the switch affordable.

We manage the furnace, gas line run, old tank coordination, ductwork modifications, and permitting as one project with one crew. See our furnace installation services across Delaware for statewide details.
Delaware has no sales tax on equipment. Stack Delmarva Power rebates with federal tax credits and the HEAR program, and your net cost drops meaningfully.
5 Signs You Need a New Furnace in Your Wilmington Home
Heat exchanger cracked on a 15+ year system
Heat exchanger repair is a major bill. On a furnace past its expected life, that money buys a fraction of a new system. A cracked heat exchanger also leaks CO. In a rowhome with shared walls, that is an immediate safety issue.
Oil furnace burning 800+ gallons per winter
At today’s pump prices for heating oil, that adds up to thousands per winter in fuel alone. A 96 AFUE gas furnace cuts heating cost by 30 to 40%. Payback on the conversion in 3 to 5 years. Natural gas available on most Wilmington streets.
Furnace short-cycles because it is oversized
Many Wilmington rowhome furnaces are 80,000 BTU in a space that needs 40,000 to 60,000. Shared walls reduce heat loss. The oversized unit cycles on, overheats, shuts off, repeats. Wastes fuel and kills components. Right-sizing on replacement fixes it permanently.
Repair bills stacking up across the last 2 years
Ignitor last year. Blower motor this year. Gas valve next year. Stacking repairs on an aging system adds up faster than monthly payments on a new one. Financing options keep the monthly number manageable.
Boiler system leaking or losing pressure repeatedly
Corroded sections in Burnham, Weil-McLain, or Peerless boilers cannot be patched forever. When sections crack, the repair involves replacing cast iron blocks. Per-section costs add up fast, and conversion to forced-air or a new boiler often makes more sense.

Furnace Installation Questions Wilmington Homeowners Ask
How much does furnace installation cost in Wilmington, DE?
It depends on system class: standard 80 AFUE single-stage, mid-range 90%+ AFUE two-stage, premium modulating condensing, or oil-to-gas conversion (the largest tier, including gas line work). No Delaware sales tax keeps real money in your pocket versus Pennsylvania or Maryland. Stacked incentives from Delmarva Power, federal tax credits, and the HEAR program reduce net cost meaningfully.
Should I convert my Wilmington oil furnace to gas?
If natural gas is available on your street, conversion saves 25 to 40% on annual heating costs. Eliminates oil deliveries and tank maintenance. The largest project tier in our furnace lineup. Stacked incentives meaningfully offset the upfront cost. Some Wilmington streets do not yet have gas infrastructure. We verify during the assessment.
What size furnace does my Wilmington rowhome need?
Smaller than you think. Shared walls reduce heat loss 15 to 25%. A typical 1,200 sq ft Wilmington rowhome needs 40,000 to 60,000 BTU. Not the 80,000 BTU units oversized installers often put in. Manual J load calculation determines the right number.
How long does furnace installation take in a Wilmington home?
One day for standard gas furnace replacement. One to two days for oil-to-gas conversion, best scheduled in summer. Two to three days for boiler-to-forced-air with new ductwork. Exact timelines during the assessment.
What happens to my old oil tank during conversion?
Separate NCC permit required. Tank is pumped, cleaned, and either removed or filled with sand or foam depending on location. We coordinate the full process as part of your oil-to-gas project.
Are high-efficiency condensing furnaces worth it in Wilmington?
Yes. 4,800 heating degree days means furnaces run 6+ months per year. A 96+ AFUE model delivers meaningful annual fuel savings versus 80 AFUE. Payback in 5 to 8 years. Qualifies for the federal 25C tax credit on qualifying high-efficiency installs and Delmarva Power rebates. One consideration: PVC sidewall venting is required, and rowhome shared walls limit venting to front or rear only.
