Heating Oil Costs Got You Down?

You’re not imagining it. Heating oil comes from the same part of crude oil as diesel fuel. When refineries go offline, demand overseas climbs or inventories run low, prices jump, and homeowners on oil feel it with every delivery.

Propane is different. The U.S. produces far more propane than it uses, much of it from natural gas production, so its price depends mostly on supply here at home.

Virginia averages for the week of October 19, 2026 (U.S. Energy Information Administration):

  • Heating oil: $6.00 per gallon
  • Propane: $3.76 per gallon

For this winter, the EIA expects homes heating with oil to spend about 21% more than last winter, while propane homes are expected to spend about 3% less.

Propane holds less heat per gallon than oil, so your real savings depend on your system. That’s why we start with a free assessment.

Electricity Prices Frustrating You?

Between rising oil prices and climbing electric rates, it can feel like your energy bills are out of your hands. They don’t have to be. You can take control, and for many homes out here, propane is the way to do it.

Why propane?

Made in America

The U.S. produces far more propane than it uses, so its price isn’t tied to global diesel markets.

R

Less heat wasted

Modern propane boilers and furnaces run up to 95% to 96% efficient.

R

Lighten your electric bill

Run your water heater, dryer, range and more on propane instead of electricity.

R

Clean and simple

No soot, no oil smell, and no oil tank in the basement.

R

Ready for outages

Propane can fuel a standby generator to keep your heat and well pump running.

Your fuel, your terms

Estimates only. Default prices are Virginia residential averages from the U.S. Energy Information Administration (week of Oct. 19, 2026). Your actual savings depend on your home, usage, equipment and fuel contract. Assumed efficiencies: oil systems 65% to 84% by age, propane burner conversion 83%, condensing propane boiler 95%, propane furnace 96%. Savings shown before installation costs. The fit score is a guide only; your free on-site assessment makes the final determination and includes a written quote.

Signs You’re Overpaying for Heat

An old oil system can waste a surprising amount of every gallon you buy.

R

Oil bills over $3,000 a winter

R

Boiler or furnace 20+ years old

R

Frequent or emergency oil deliveries

R

Soot, smoke or oil odors

R

Uneven heat or cold rooms

R

Repairs every heating season

Older oil systems often run at 65% to 75% efficiency, which means a quarter or more of every gallon goes up the chimney. A new high-efficiency system can cut that waste dramatically.

How Our Free Heating Assessment Works

  1. We look at your system: its age, condition, efficiency and how it heats your home.
  2. We review your fuel use: your oil deliveries or bills from last winter.
  3. We compare your options: a propane burner conversion on your existing boiler, a new high-efficiency propane boiler, or a new propane furnace.
  4. You get a written quote and estimated yearly savings, with no pressure to decide.

We’ll also walk you through what happens with your propane tank and your old oil tank, so there are no surprises.

Oil to Propane Conversion FAQs

Is propane cheaper than heating oil?

Per gallon, yes, by a wide margin right now. In Virginia, heating oil averaged about $6.00 a gallon and propane about $3.76 the week of October 19, 2026, according to the U.S. Energy Information Administration. A gallon of propane holds about two-thirds the heat of a gallon of oil, so your real savings depend on how efficient your old and new equipment are. Our calculator and free assessment factor that in.

How much can I save by converting from oil to propane?

It depends on how much oil you use, how old your system is, and what you replace it with. Homes with older boilers that use 700 gallons or more a year can often save $1,000 or more a year with a new high-efficiency propane system. A burner-only conversion saves less, but costs less upfront.

Can I convert my oil boiler to propane?

Often, yes. If the boiler is in good condition, we can install a propane burner on it. If it is old or inefficient, replacing it with a condensing propane boiler usually saves much more over time.

What happens to my old oil tank?

When you switch, the old oil tank needs to be emptied and either removed or properly abandoned. We will explain your options during the assessment.

Do I need a propane tank?

Yes. Propane is stored in a tank on your property, either leased from a propane supplier or owned. Owning your tank lets you shop around for the best propane price.

Can other appliances run on the same propane tank?

Yes. The same propane tank that heats your home can also run a tankless water heater, clothes dryer, range and oven, outdoor grill, gas fireplace and even a standby generator. Our licensed plumbers run the gas lines and make the connections, so everything is installed safely and to code.

Is the heating assessment really free?

Yes. We look at your system and your fuel use, then give you a written quote and savings estimate with no obligation.

Phenomenal company that goes above and beyond. Our family genuinely appreciates their vast array of skills, rapid response, expertise & professionalism. Honest and hard workers. We had multiple issues and in a matter of days we had two different people out to the house to take care of everything. They are fast and professional and do excellent work!!! I forgot to take pictures but we had issues ranging from leaking pipes, to stuff stuck in our drain (kids), electrical outlet issues, post-fire check of electrical in addition to the install of a dishwasher. We’ve also had HVAC repair and well services. Everything is always top notch and the best possible work you can get. We will continue to use their services!

We’ve HVAC maintenance done (thankfully) and greatly appreciate the care and effort to ensure our system could stand up to the heat. They came out & did a full checkup & preventative maintenance on our system & stopped an emergency before it would’ve ultimately occurred. Greatly appreciate their consistency & efficiency. Austin and his team are extremely hard workers & are always prepared for the situation. They’re willing to explain and provide recommendations & solid solutions to complex issues. Truly thankful for this company.
