How much does oil to gas conversion cost in Watertown?

Conversion costs typically range from $8,000-$15,000 depending on your home’s specific requirements. This includes the new gas furnace, gas line installation from the street, interior piping, permits, and labor.

Factors affecting price include distance from the gas main to your house, basement accessibility, and whether electrical upgrades are needed. We provide detailed written estimates with no hidden fees.

Most homeowners save $1,500-$3,000 annually on heating costs, so the investment typically pays for itself within 3-5 years through energy savings alone.

Most residential conversions take 1-2 days for the actual installation work. However, the full process from initial consultation to completion typically takes 2-3 weeks due to permit processing and scheduling with National Grid.

We coordinate all the moving parts—permits, gas company scheduling, and equipment delivery—so you don’t have to manage multiple contractors and agencies. You’ll have a clear timeline upfront.

During installation, you’ll have temporary heating if needed. We don’t start removing your old system until the new one is ready to go online.

Yes, you need permits from both the Town of Watertown and National Grid. The town requires a plumbing permit for gas line installation, and National Grid requires approval for new gas service connections.

We handle all permit applications and inspections as part of our service. This includes submitting proper documentation, scheduling required inspections, and ensuring everything meets current Massachusetts plumbing codes.

Attempting DIY gas work or using unlicensed contractors can result in failed inspections, safety hazards, and insurance issues. All our technicians are licensed and insured for gas line installations.

Beyond heating, having gas service allows you to add other gas appliances like tankless water heaters, gas ranges, and dryers, further increasing your home’s appeal and functionality.

Modern natural gas systems are extremely safe when properly installed and maintained. Natural gas is lighter than air, so leaks dissipate upward rather than pooling like oil or propane. Gas systems also have multiple built-in safety shutoffs.

Oil systems carry risks of tank leaks, which can cause expensive soil contamination and environmental cleanup costs. Underground oil tanks are particularly problematic as they age and develop leaks.

All our gas installations include proper ventilation, gas leak detection, and safety shutoff systems that meet current Massachusetts codes. We also provide guidance on carbon monoxide detectors and annual maintenance requirements.
