Heating system conversions
Trade the Oil Tank for a Modern System
Oil-to-gas, steam-to-hot-water, fossil-to-heat-pump — we handle the whole conversion, from the utility paperwork to the last radiator bled.
Oil, steam & legacy systems
Philadelphia is full of heating systems outliving their era.
Oil furnaces feeding from basement tanks. Steam boilers installed when Truman was president. Electric baseboard bleeding money in every room. These systems still run — but every year they run costs more than it should, and every year the conversion math gets better.
A conversion is more than swapping a box: gas service coordination with the utility, chimney lining, tank decommissioning, piping changes, and a new system sized to your home rather than to 1952. AJM has run this play across Philly and South Jersey for years — we know the utility process, the permits, and the pitfalls.
Oil-to-gas converts typically cut fuel costs 30-50%. Heat pump conversions can beat even that, with current incentives stacked on top. We'll price your specific conversion honestly — including the parts other quotes conveniently leave out, like tank removal and chimney work.
What's included
The whole conversion, one contractor
Gas coordination, new equipment, chimney lining, and oil tank decommissioning — end to end.
Above-ground tank decommissioning and removal handled safely and to code.
Where piping allows — modern comfort and efficiency from your existing radiators.
All-electric conversions with cold-climate heat pumps and current incentives applied.
Replace the most expensive heat there is with ductless or ducted systems that cost half as much to run.
We run the process — applications, inspections, and scheduling — so you don't have to.
Know the warning signs
Six signs it's conversion time
Oil pricing is volatile and rarely kind. Every delivery is a reminder the meter's running.
Tank failures are environmental cleanups, not just repairs. Converting retires the risk entirely.
A 40-year-old system runs at 60-70% efficiency. Modern equipment starts at 85% and climbs.
If the main runs past your house, the hardest part of oil-to-gas is already done.
Resistance baseboard is the priciest heat sold. Heat pumps deliver the same warmth for a fraction.
When components need hunting on eBay, the system is telling you something.

How it works
How a conversion runs
- 1Feasibility & real quote
We check gas availability, chimney, and piping — then quote the whole job, hidden costs included.
- 2Paperwork handled
Utility applications, permits, inspections — we run the process and keep you posted.
- 3Conversion week
Old system out, new system in, tank decommissioned. Most conversions: 2-3 days of onsite work.
- 4Commissioned & documented
System tuned, inspections passed, paperwork delivered. You just feel the difference monthly.
Common questions
System Conversions FAQs
How long does an oil-to-gas conversion take?
Onsite work is typically 2-3 days. The utility's gas service timeline is the variable — anywhere from a couple of weeks to a couple of months — which is why we start that paperwork first and schedule around it.
What happens to my old oil tank?
It gets professionally decommissioned — drained, cleaned, and removed (or filled in place where removal isn't practical), documented to code. Never just abandoned; an abandoned tank is a liability that surfaces at sale time.
Is my chimney okay for a gas system?
Usually it needs a liner — gas exhaust is cooler and wetter than oil's and corrodes unlined masonry. It's a standard part of the job and it's in our quote from day one, not a surprise change order.
Should I convert to gas or go straight to a heat pump?
Genuinely depends on your rates, your ducts or radiators, and incentives. We'll price both paths with real numbers — we install both, so we have no thumb on the scale.
