Oil Furnaces

Heat Cool and Happy offers professional oil furnace installation, replacement, and repair services in Greencastle, PA and surrounding Franklin County communities.

Oil furnaces run differently than gas systems — fuel line, nozzle, and tank all matter — so getting the details right up front means fewer surprises down the road.

Our oil furnace installation and replacement service includes:

• A full home evaluation to size the right furnace for your space — including a check of your existing ductwork
• Safe removal and disposal of your old furnace
• Fuel line and oil tank inspection, checked for leaks and secured properly since oil systems store fuel on-site
• Nozzle, burner, and flue setup, tested to make sure the system burns clean and drafts properly
• A walkthrough of your new system so you know how to run it — thermostat, filters, and what to watch for down the road

Oil systems store and burn fuel differently than gas, so we pay close attention to the fuel line, tank condition, and flue — that's where most oil furnace issues actually start.

A few signs point to oil furnace problems that repair won't fully solve:

• You're burning through oil faster than you used to. Rising fuel consumption for the same amount of heat usually means the furnace is losing efficiency, not that winter got colder.
• Your tank shows any sign of rust, staining, or leaking. A failing tank isn't something to patch — it's a safety and environmental issue that often makes sense to address alongside a furnace replacement.
• You're seeing soot around the furnace or on nearby walls. Soot buildup usually means incomplete combustion, and it gets worse (and dirtier) the longer it's ignored.
• The burner keeps resetting or won't stay lit. Repeated ignition failures are a common sign the burner or nozzle system is wearing out, not a one-time fluke.
• You smell fuel oil inside the house. Unlike gas, oil odor indoors usually points to a fuel line or tank issue nearby — worth having checked promptly.
• It's 15-20+ years old and due for its next major service. At that age, the cost of keeping it running often starts outweighing the cost of replacing it.

If a few of these sound familiar, it's worth getting the system evaluated before you're stuck without heat mid-winter.
