Furnace Repair in West Marlborough and Doe Run, PA
Seventeen square miles of pasture, and almost no gas main.
West Marlborough is one of the most rural townships in southern Chester County, with preserved farmland, horse farms and very old stone houses. Most homes heat with oil, and many have barns and outbuildings that need heat too. This page explains what tends to go wrong and how to get connected with an independent local heating company.

Why West Marlborough homes have the heating problems they do
Land preservation kept West Marlborough rural, so gas mains never arrived, and the housing stock stayed old. That combination means oil and propane, aging boilers, buildings that were never designed for central heat, and long drives for every service call.
The biggest reason is the King Ranch. For decades it was the largest landowner here and in adjoining townships. In the 1980s its 5,367-acre property was bought and protected with conservation easements, which led to tens of thousands more acres being preserved around it. Horses have since replaced cattle as the main livestock. Without new subdivisions, there was little reason to extend gas lines. In 2000, just 1% of homes used utility gas.
The houses themselves are old. Nearly half predate 1940, and many were heated by fireplaces or stoves when built. Later owners added boilers, radiators, oil furnaces and the odd heat pump. Wood and even coal still showed up in the 2000 Census. Each layer adds its own failure points.
Then there's the land. Open pasture and hilltops catch wind that sheltered village streets don't. Barn dust and hay clog filters. Outbuildings, tack rooms and workshops often have their own heaters on separate tanks.
Heating problems seen most in West Marlborough
These are typical patterns for a township with this housing and fuel mix.
Running out of oil
A dry tank stops the burner, and sludge from the bottom can clog the filter and nozzle. The fix is often a delivery, a new filter and nozzle, and bleeding the line. Automatic delivery prevents most of these. See oil furnace repair.
Oil burner lockouts
Dirty nozzles, weak fuel pumps, failed photocells and soot cause lockouts. Press the reset button once only. If the burner won't stay lit, call. Repeated resets can flood the chamber.
Old boilers and radiators
Pre-1940 farmhouses often run hot water or steam from an oil boiler. Failing circulators, low-water cutoffs and leaking sections are common. See boiler repair.
Propane run-outs and frozen regulators
Propane homes and outbuildings can run dry or have a regulator ice up in a storm. After a run-out, the system needs a leak check before it's relit. See propane furnace repair.
Heat in barns and outbuildings
Unit heaters, radiant tube heaters and mini splits in barns, tack rooms and workshops fail too, often from dust and rodents. Keep them on your service list.
Chimneys and carbon monoxide
Old masonry chimneys venting oil burners can crack, clog or lose their liner. Soot or a fuel smell means stop and call. Read our carbon monoxide guide.

West Marlborough history that shapes its heating
West Marlborough split from Marlborough Township in 1729, the same year as East Marlborough. It grew around mills on Buck Run and Doe Run, then became cattle and horse country. That history left very old houses and a landscape that preservation kept almost unchanged.
Buck Run and Doe Run powered the township's early mills. Doe Run's gristmill dates to 1744. A cotton mill there was later replaced by a town hall in 1898, which then served as a dairy.
Fox hunting shaped the land too. W. Plunket Stewart's Cheshire hunt hired its first huntsman in 1914. Stewart persuaded Robert Kleberg of the King Ranch in Texas to buy a large farm here, and the ranch later doubled its holdings. Texas cattle came north by rail to fatten on these pastures. When the ranch looked to sell in the early 1980s, the Brandywine Conservancy and local hunt members helped preserve it. The 771-acre Laurels parcel at its center was protected in 1985 and is now a nature preserve.
For heating, that story explains a lot. Few new homes were built, so the township kept its stone farmhouses, tenant houses and estate homes. Systems were added one building at a time, often on whatever fuel the farm already had. Our guide to heating old stone homes goes deeper.
What to expect when a heating company comes out
From Unionville village, the main road in is PA 82, which turns west onto Doe Run Road at the roundabout and runs through farmland to Doe Run. Give exact directions, gate codes and which building needs service.
The route from Unionville
PA 82 and PA 842 share Doe Run Road through Unionville. PA 842 splits off southwest on Upland Road, forming part of the border with East Marlborough. PA 82 continues northwest to Doe Run, where PA 841 begins, then crosses Buck Run into East Fallowfield. Street Road (PA 926) crosses the south of the township.
In ice and snow, hills and narrow lanes slow every driver. Farm lanes and long driveways may need plowing before a van can reach the house.
Help the technician find you
- Give your road and the nearest crossroad, not just the town name.
- Share gate codes, and say whether the call is for the house, a barn or a guest house.
- Have the oil or propane tank reading and supplier's name ready.
- Keep dogs and loose horses secured near the work area.
- Turn on an outside light for evening calls.
A winter checklist for farm and estate owners
On a rural property, most heating failures are preventable with fuel planning, yearly service and a plan for outages.
- Put every tank on automatic delivery, or read each gauge weekly from December to March.
- Have oil burners cleaned and tuned every year. See the tune-up checklist.
- List every heater on the property: house, guest house, barn, tack room, workshop.
- Change furnace filters monthly in winter. Barn dust and pet hair clog them fast.
- Have chimneys venting oil or wood inspected, and fix missing liners.
- Fit CO alarms near bedrooms and on each level with a fuel-burning appliance.
- If you have a generator, keep it outside and use a transfer switch installed by an electrician.
Oil, propane, electric and gas in West Marlborough
PECO supplies electricity. Natural gas is rare: in 2000 only 1% of homes used it. Most households rely on heating oil, with propane, electric heat pumps, wood and a little coal making up the rest.
Heating oil
The main fuel, at 64% of homes in 2000. Old tanks, sludge and burner service are everyday issues.
Oil furnace repairPropane
About 9% in 2000, and common in newer homes and outbuildings. Watch for run-outs and frozen regulators.
Propane furnace repairElectric and heat pumps
About 20% in 2000. A heat pump can cut oil use and add cooling, with oil kept as backup.
Heat pump repairWood and coal
Still 6% combined in 2000. Stoves and chimneys need yearly cleaning and CO alarms nearby.
CO safetyHeating questions from West Marlborough homeowners
Can I get natural gas in West Marlborough?
It's unlikely. Only about 1% of homes used utility gas in the 2000 Census, and preserved farmland means few mains. Call PECO with your address to be sure before planning a conversion.
I ran out of oil. What do I do?
Call your supplier for a delivery. Don't keep pressing the burner reset. After a run-out, the filter, nozzle and line often need service before the burner restarts, so you may need a technician too.
My propane tank ran dry. Can I just relight the furnace?
No. After a run-out, the system needs a leak check before it's relit. Your propane supplier or a qualified technician should do it.
Can one visit cover the house and the barn heater?
Often, if you ask when you book. Tell the company every unit you want looked at, the fuel each uses and where each one is. It saves a second trip.
Should I switch from oil to a heat pump?
Many rural owners add a heat pump and keep oil for the coldest nights. That cuts oil use and adds air conditioning. Get written quotes for both a straight replacement and a dual-fuel setup, and check PECO's current rebates.
Is a no-heat call on a farm an emergency?
It's urgent in freezing weather, especially with older adults, infants or someone ill in the house. A gas or heavy fuel smell, soot or a CO alarm is an emergency: get out and call 911 from outside.
Is help available to pay for heating oil?
Yes. LIHEAP runs from November 2, 2026 to April 23, 2027 and covers oil and propane. Cash grants range from $200 to $1,000 for eligible households, with crisis grants for emergencies. Apply through COMPASS or the Chester County Assistance Office.
