Pittsburgh proper is a gas city, and this guide will be honest about that in a moment. But ring the city and the fuel map changes: oil tanks persist in the river towns, in older Washington and Fayette county stock, in the rural stretches of Westmoreland and Armstrong counties past the gas mains, and electric baseboard hides in flats and conversions across the region. For those households the annual heating spend is a large share of the yearly utility bill, and the 2026 comparison deserves a clean run. Here it is, fuel by fuel, with the honest gas answer included, because Western Pennsylvania households deserve the version that matches their own basement.
The Oil Baseline
An oil-heated house of ordinary size in this climate burns hundreds of gallons a winter; a Western Pennsylvania January does not ration itself. Fuel arrives in deliveries, and an annual service contract sits on top of the gallons. This page does not print a per-gallon price. That number moves between deliveries, and this page has no official source for it.
Then the costs without a neat receipt: a driveway that must stay passable for the truck, and a tank whose failure mode is an environmental remediation story.
The Heat Pump Side
A modern cold-climate heat pump moves heat rather than making it, delivering two and a half to three units of heat per unit of electricity across the season, and the current generation holds capacity through a Pittsburgh winter, per our equipment guide. Serving the same load, the electricity is a smaller annual spend than the oil it replaces. This page does not print that electricity as a dollar figure. A bid can price the rate schedule for the house. A guide cannot invent it.
Oil pays for fuel deliveries and a service contract, and cooling is a second system or a set of window units. A cold-climate heat pump pays for electricity, covers cooling in the same machine, and drops the delivery contract. The direction of the difference is the point. The dollar amount is the bid.
A River-Town Picture
A frame house in a Beaver County river town burns a winter of oil plus a service contract. A properly sized cold-climate system carries the same house on electricity. The difference repeats every winter the house stands. This page does not print that difference in dollars, because a per-gallon price, a contract, and an electricity band would have no official link and no checked date.
Against a conversion, the fuel difference is the reason oil households look at the project, and it shows up sooner where the old cooling was due anyway. Programs, with their official links and checked dates, are in the rebates guide. This comparison does not add an incentive figure to the operating difference. Install scope, without an unsourced price band, is in the installation cost guide.
The Honest Gas Paragraph
Now the common case. The city and the inner suburbs heat with gas, and the gas math is genuinely close. Gas is cheap per unit of heat, and a sound furnace in a Squirrel Hill foursquare or a Mount Lebanon Tudor is not a problem needing rescue.
For gas households the strong cases are specific, and worth naming precisely: the air conditioner is at end of life, so one machine replaces two systems and the comparison is heat pump versus furnace-plus-new-AC, which the heat pump frequently wins; the house has no ducts, where ductless heating-and-cooling beats window units on comfort alone; or a party-walled rowhouse's load is so small the whole project stays modest. What no honest bidder tells a gas household is that fuel savings alone repay the conversion the way they do for oil. They usually do not. A pitch claiming otherwise is a pitch, and the vetting questions in our contractor guide exist for exactly that moment.
Electric Baseboard
The stock that heats with resistance baseboard, older flats, conversions, some postwar infill, gets the shortest analysis of all. Baseboard delivers one unit of heat per unit of electricity; a heat pump delivers two and a half to three. The heating portion of the electric bill drops by more than half, with no tank, no deliveries, and no combustion anywhere in the story. For these households the only real questions are sizing and head placement.
Volatility, the Cost Nobody Budgets
Oil's final cost is unpredictability. World events move the per-gallon price between deliveries, and a cold snap can land a large invoice in the same month as the holidays. Electric rates move too, but through regulated filings, in steps a budget can see coming. Converted households report the same pattern every time: the savings were expected; the flat, predictable bill was the part they would not give back.
The Radiator Question, and the First Winter
Most oil homes here distribute through radiators, and they do not need to come out. The standard conversion runs ductless heads through the living space and leaves the radiators silent in place. The cautious version of the plan is common and sensible in this climate: install in fall, keep the oil system as backup through the first winter, watch the heat pump carry the cold nights, then retire the tank in spring. Programs for the electric bill are in the rebates guide. They are not added into the fuel comparison above.
The Tank Itself, an Ending Worth Naming
One more line belongs in the oil household's ledger: the tank. A buried or basement oil tank is a liability that appreciates in the wrong direction. Insurers increasingly ask about tank age at renewal, buried tanks complicate home sales in every river town where they are common, and a leak turns into a remediation project. Retiring the tank at conversion, pumped out, cleaned, removed or properly decommissioned, belongs on the quote as its own line. Fold it into the project rather than leaving it for the eventual sale, when it becomes the buyer's leverage instead of your choice. This page does not print a price for that work. The site, buried or inside, sets it.
What the Summer Adds for Free
The comparison above is about heating, but half the machine works in July. Much of the region's oil and baseboard stock cools on window units or nothing, and the same conversion that retires the tank delivers real cooling and dehumidification into stock that has never had it. Price that honestly when weighing the project: the alternative is not zero, it is another decade of hauling window units up from the basement while the valley humidity wins. For many converted households the summer half of the machine is the part guests notice first.
Cooling counts in a Pittsburgh July, and it counts double in the stock that never had central air: the same machine that retires the oil burner retires the window units and dehumidifies the valley air properly while it is at it.
