Quick answer

Naugle services oil furnaces and handles oil-to-gas and oil-to-heat-pump conversions across Lenawee County, MI. Turnkey conversion quotes include the new equipment, gas line tap and run, oil tank removal and proper disposal, and utility coordination — not a 'we install the furnace and you find a gas guy' situation. Federal 25C tax credit paperwork filed on heat pump conversions. Call or text 517-423-3121.

Oil furnace repair and replacement

Oil furnaces aren't going anywhere overnight — there are still hundreds of homes in Lenawee, Hillsdale, and Washtenaw counties running on oil. We service every major oil-fired furnace and boiler brand, keep common parts on hand, and quote repair vs. replacement honestly.

Converting from oil to natural gas

If natural gas is available at the street, converting almost always pencils out within 5-7 years on fuel savings alone. Operating cost on natural gas runs roughly half of oil in our service area, and you eliminate the oil tank, deliveries, and tank-leak liability that comes with oil heat.

Our conversion quote includes everything: new high-efficiency gas furnace, gas line tap and run, oil tank removal and proper disposal, and coordination with the utility for new service. Turnkey — not a 'we install the furnace and you find a gas guy' situation.

What an AMAZING company! I know we will be using them as needed for years to come. We had our central air replaced today. I can't say enough about this company!

Was referred to Naugle by a friend and they are fantastic!
B. P., Adrian
Called at 7 AM with no heat — they had a tech here by 9:30 and we were warm again before noon. Fair price, no upsell. Exactly what you want.

FAQ

Oil Furnaces questions, answered

Yes. Oil furnaces are less common than they used to be, but plenty of older Lenawee County homes still run on oil. We tune up, repair, and replace oil furnaces, and we handle the change-over to natural gas or propane when that's the better play.

How financing fits with your install

  • Same equipment options. Financing doesn't change what we install or how — only how you pay for it.
  • Multiple plan lengths. Short-term 0% APR promos through longer-term loans, so the payment fits the household budget.
  • Decision at the estimate. We bring the lender right to your kitchen table. Approval is typically a few minutes.
  • Stack with rebates. Financing works alongside any utility rebate or federal tax credit you qualify for — we file the paperwork.

Financing through third-party lenders. Terms and approval depend on credit qualification, loan product, and equipment.
