Oil-to-Gas Furnace Conversion in Durham Region: What Homeowners Should Know

A lot of older homes across Pickering, Ajax, Whitby, Oshawa, and Clarington were built when oil heat was standard for the area, and natural gas has only reached some of those streets more recently. If gas is now available at your property, converting usually means lower fuel costs and simpler service than oil, but it's a real project, not a drop-in swap.

This is step one, before anything else gets planned — your local gas utility confirms whether a service line reaches your property or what it costs to extend one. Everything downstream of this depends on the answer, so it's worth confirming before you fall in love with a specific furnace.

An old oil tank — indoor or buried — needs proper decommissioning or removal, and a buried tank in particular can turn into an environmental question if it's leaked. We coordinate this as part of the conversion rather than leaving you to sort it separately after the new furnace is already in.

Oil furnaces vent differently than gas furnaces, so the chimney or venting setup usually needs to change, not just the equipment in the mechanical room. Gas piping has to be run and pressure-tested, and older electrical panels sometimes need a look depending on what else is going in. We map this out on the quote, not as change-order surprises mid-install.

Depending on what you're installing, a high-efficiency gas furnace or a cold-climate heat pump paired with gas backup may qualify for Home Renovation Savings Program incentives — worth confirming eligibility before you order equipment, since amounts depend on your specific setup. We walk through what's realistic on your written quote.
