We Leave Our Customers Smiling
Ready for 5-Star Level Service?
You wake up to consistent warmth without worrying about oil deliveries or empty tanks. Your heating bills drop by thousands each year because natural gas costs significantly less than oil to produce the same amount of heat.
You get a cleaner system that doesn’t leave soot, ash, or sulfur buildup requiring constant maintenance. Your basement gains space without that bulky oil tank, and your home value increases with modern, efficient heating that buyers actually want.
The reliability alone changes everything. No more scheduling deliveries, no more running out of fuel during storms, no more price shocks when oil spikes. Just consistent, affordable heat delivered through underground pipelines.
We started as an oil company in Ocean Grove’s Bristol County area over 30 years ago. We’ve seen firsthand how oil heating costs have climbed while gas prices stayed stable.
Since 2001, we’ve expanded into full HVAC and plumbing services, completing hundreds of oil to gas conversions across Massachusetts. Our NATE-certified technicians know exactly what works in Ocean Grove’s climate and housing stock.
We’re still family-owned, still local, and we still answer our own phones. When you call Dempsey Energy, you talk to someone who works here, not a call center in another state.
First, we assess your current system and home layout to determine the best approach for your oil to gas conversion in Ocean Grove. We handle all permits, inspections, and utility coordination so you don’t have to navigate the bureaucracy.
Next, we install the gas line from the street to your home (if needed) and set up your new gas heating equipment. Our fully stocked trucks mean we complete most conversions without delays or multiple trips.
Finally, we test everything thoroughly, coordinate the final inspection, and arrange for your gas meter installation. We also handle removal of your old oil tank and equipment, leaving your basement clean and ready for better use of that space.

Your oil to gas conversion includes complete system design, all necessary permits, gas line installation, new high-efficiency heating equipment, and thorough testing. We coordinate with National Grid for meter installation and handle all inspections.
Ocean Grove homeowners typically see 30-50% reductions in heating costs after converting from oil to gas. With Massachusetts oil users spending nearly $6,000 annually compared to $3,000 for natural gas users, the savings add up quickly.
We also include removal and proper disposal of your old oil tank and equipment. Many Ocean Grove homes built before 1980 have basement oil tanks that free up valuable space once removed. Your new gas equipment takes up far less room and operates much more quietly than old oil systems.
