Oil to Gas Conversion
Oil to gas conversion replaces your oil-burning boiler or furnace with equipment that runs on natural gas. Your fuel comes straight from the utility line. You stop waiting on delivery trucks and checking the tank gauge in the middle of January. For most Connecticut homeowners, the switch happens when an older system starts showing its age. Don’t wait for it to quit on a freezing night. Plan so you can choose your new equipment without the pressure of a breakdown.
Why Homeowners Make the Switch to Natural Gas
Natural gas arrives through a utility line, so your supply never runs dry between deliveries. An oil-to-gas conversion also frees up the space your old tank used to occupy. Here is what homeowners notice most:
- No tank monitoring or fuel delivery scheduling
- Cleaner combustion with fewer odors and less soot
- Modern gas furnaces rated up to 98% AFUE
- Access to efficient gas water heaters and appliances
Gas also pairs well with a full heating installation when your current system is past repair. A quick evaluation will tell you whether fixing or replacing your equipment makes more sense.
Choosing Between a Gas Boiler and a Gas Furnace
Homes with radiators or baseboard heat usually call for a boiler replacement oil to gas upgrade. Forced-air homes typically move to a high-efficiency gas furnace instead. The efficiency gains can be significant. According to ENERGY STAR, certified gas boilers carry AFUE ratings of 90% or greater. Certified oil boilers start at 87%.
| Feature | Oil Heating | Natural Gas Heating |
|---|---|---|
| Fuel supply | Truck deliveries to a tank | Piped in by the utility |
| On-site storage | Oil tank required | No tank needed |
| Combustion | More soot and odor | Cleaner burn |
| ENERGY STAR boiler rating | 87% AFUE or greater | 90% AFUE or greater |
How an HVAC Oil to Gas Conversion Works
Every conversion starts with a close look at your current setup. The process usually follows these steps:

- Gas service coordination with your utility
- Oil equipment removal and new system installation
- Safety testing and a walkthrough of your controls
