Plenty of older homes across the North Hills and the wider Pittsburgh area still heat with oil — and their owners are tired of price swings, oil deliveries, and a tank in the basement or yard. Converting to natural gas is one of the higher-impact upgrades a home like this can make: gas is typically cheaper and more stable than oil in this region, the heat is cleaner, and you lose the delivery schedule and the tank entirely.
A proper conversion is more than swapping a furnace. We evaluate whether natural gas is available at the street and the meter, coordinate the gas service and line where needed, size a high-efficiency gas furnace or boiler to your home with a load calculation, handle the venting and combustion-air requirements, and deal with the old oil equipment. Every step is permitted and inspected because this is fuel-gas work that must be done to code.
The result is a modern, efficient heating system with lower operating cost and cleaner operation, installed by a contractor who does the sizing and the safety work properly rather than cutting corners on a fuel conversion.

Reasons homeowners convert to gas
- High and unpredictable oil prices and delivery costs
- An aging oil furnace or boiler due for replacement
- Wanting to remove an oil tank from the basement or yard
- Natural gas already available at the street
- Soot, odor, and the maintenance that comes with oil heat
- A push for cleaner, more efficient heating
What our oil-to-gas conversion covers
Furnace & boiler conversions
Convert oil-fired furnaces or boilers to efficient natural-gas equipment sized to your home.
Gas service coordination
We handle the gas-line and service coordination and the venting and combustion-air requirements.
Permitted fuel-gas work
Every conversion is permitted and inspected — this is safety-critical work done to code.
Old-equipment removal
We deal with the old oil furnace, boiler, and tank so you are not left with the cleanup.
Our process
Gas availability check
We confirm natural gas service at the street and meter and identify what the gas line and service require.
Load calculation & design
We size a high-efficiency gas furnace or boiler with a Manual J calculation and plan venting and combustion air.
Permitted conversion
We pull the Pittsburgh mechanical and fuel-gas permits, install to code, and coordinate the old oil-equipment removal.
Startup & documentation
We complete combustion testing and startup, then document warranties and the completed permit.
Why a conversion is more than a furnace swap
Converting from oil to gas is fuel-gas work, and doing it right means more than dropping in a new furnace. We confirm natural gas is available at the street and meter, coordinate the gas service and line where needed, size high-efficiency equipment to your home with a load calculation, handle the venting and combustion-air requirements, and deal with the old oil furnace and tank. Every step is permitted and inspected because this is safety-critical work. The single biggest variable in the cost is how far the gas has to travel to reach you, which is why we confirm availability first and put the full scope — gas work, equipment, permits, and tank removal — in writing.
What affects the cost
A conversion is a planned project quoted after we assess the home and gas availability. Cost drivers include:
- Whether gas service and a meter already exist, or must be brought in
- The furnace or boiler capacity and efficiency selected
- Venting, combustion-air, and gas-line requirements
- Removal and disposal of the old oil equipment and tank
Conversion cost depends heavily on gas availability and the new equipment. We give you a written scope covering the gas work, equipment, permits, tank removal, and warranty before you commit.
| Factor | Lower cost | Higher cost |
|---|---|---|
| Gas service | Meter already present | Service must be extended |
| Equipment | Furnace only | Furnace and boiler |
| Venting | Sidewall PVC | Chimney liner needed |
| Old tank | Above-ground removal | Underground tank |
Why choose Werth-Aire for oil-to-gas conversion
A conversion is safety-critical fuel-gas work, and we do it by the book — confirming gas availability, sizing the new equipment, pulling the permits, and hauling the old oil tank away so you are not left with the cleanup.
