Oil to Gas Conversion | Derry, NH

⚡

Oil to gas conversions are one of the best investments a homeowner in southern New Hampshire can make right now. Natural gas typically costs less per BTU than heating oil, burns cleaner, and powers a wider range of high-efficiency equipment. The Air Department handles the complete conversion in Derry and surrounding NH towns: removing the old oil equipment, installing a new high-efficiency gas furnace or boiler, and managing the gas line connections and permits.

The cost difference between oil and natural gas has been significant in recent years. NH homeowners who converted have reported meaningful reductions in annual heating costs, and the newer high-efficiency gas equipment that replaces old oil units compounds those savings further. Gas furnaces and boilers also tend to require less maintenance than oil equipment and last longer. The upfront cost of a conversion is typically recovered within a few years of lower fuel bills.

The conversion process involves several steps: disconnecting and removing the old oil burner or furnace, draining and removing the oil tank if it is indoors, installing the new gas appliance, running the gas line from the street or existing gas meter to the equipment, and pulling the required permits from the town. Brad handles all of it and coordinates with the gas utility to schedule the meter connection. In most cases the entire job is done in one to two days.

Natural gas service is available throughout Derry, Londonderry, and most of the surrounding communities served by Liberty Utilities (formerly National Grid NH). If you are not sure whether gas is available at your address, Brad can find out before you commit to anything. He is licensed for gas work in both New Hampshire and Massachusetts, so whether your home is on either side of the border, he can handle the job.

Common Questions About Oil to Gas Conversion in Derry, NH

How much does an oil to gas conversion cost in New Hampshire?

The cost depends on the equipment selected, whether the indoor oil tank needs to be removed, and the distance from the existing gas meter or street main to the equipment. A typical residential conversion ranges from $4,000 to $8,000 for equipment and labor. High-efficiency equipment may qualify for Mass Save rebates (MA) or federal tax credits (NH) that bring the net cost down significantly. Brad provides a detailed estimate before any work begins.

How long does the oil to gas conversion process take?

Most residential conversions take one to two days from start to finish. That includes removing the old equipment, installing the new gas appliance, running the gas line, and completing the permit inspection. The gas utility connection may take an additional few days to schedule depending on availability.

Is natural gas available in Derry, NH?

Natural gas is available throughout most of Derry, Londonderry, and surrounding towns served by Liberty Utilities. Whether gas is available at your specific address depends on the proximity of the distribution main. Brad can verify availability before you invest time in planning a conversion.

What happens to my oil tank during the conversion?

If you have an indoor oil tank, it needs to be drained and removed as part of the conversion. Brad includes tank removal in the conversion scope. Outdoor buried tanks are handled separately and typically involve an environmental contractor. Brad can advise on next steps if you have a buried tank.
