Furnace and Heat Pump Repair in Pennsbury Township, PA
The most electric-heated corner of the Brandywine, under a lot of trees.
Pennsbury was one of the few townships nearby where electricity, not gas or oil, was the top heating fuel in the 2000 census. Most homes date from the 1970s and 1980s and sit on wooded lots along winding roads. This guide covers what that means for heat pumps, oil burners and power outages, and how to get connected with a local heating company.

Pennsbury heating conditions, in one table
Pennsbury is a 10-square-mile township of wooded lots, farmsteads and 1970s and 1980s homes between Kennett Township and the Brandywine. Electric and oil heat dominated in the last census breakdown available, and gas reached only a small share of homes.
| Factor | Pennsbury Township | What it means for heating |
|---|---|---|
| Municipality | Township in Chester County; separated from Kennett Township in 1770 | Township office uses a Chadds Ford 19317 address |
| Population | 3,876 at the 2020 census, per the township's own data | Low density, spread-out homes |
| Age of residents | Median age 50.9 and 28% aged 65 or older in 2010 | Plan ahead for no-heat events; check on neighbors |
| Housing age (2000) | 29% built in the 1970s, 29% in the 1980s; 13% before 1960 | Many homes on replacement heat pumps and oil systems |
| Housing type (2000) | 64% detached, 20% attached, about 10% in buildings of 20+ units | Townhouse and condo communities alongside large lots |
| Heating fuel (2000) | Electric 40%, oil 35%, utility gas 14%, propane 11% | Heat pumps and oil burners lead repair calls |
| Roads | US 1 (Baltimore Pike), PA 52 (Lenape Road, Kennett Pike), PA 926 (Street Road) | Main routes plus many narrow wooded township roads |
| Historic sites | About ten National Register listings, including the Fairville Historic District | A handful of very old homes with special venting needs |
The fuel and age figures are from the Census 2000 housing profile, the most recent breakdown for the township that could be retrieved. Some homes have since changed fuels.
Why Pennsbury homes have the heating problems they do
Pennsbury was built out mostly in the 1970s and 1980s, largely beyond the gas mains, under heavy tree cover. That combination explains its reliance on electric and oil heat and its exposure to outages.
Built when electric heat was popular. More than half the homes counted in 2000 went up between 1970 and 1989. With 40% of homes on electric heat in 2000, heat pumps, electric furnaces and baseboard heat are all common. Those original heat pumps have usually been replaced at least once. The ductwork and wiring usually haven't.
Oil where gas didn't reach. Oil heated about a third of homes in 2000, including many farmhouses and larger houses. Oil systems need yearly cleaning, and tank age becomes a question in older properties.
Trees and power lines. Pennsbury's wooded lots and winding roads are a large part of its appeal. They also put branches over power lines. Every modern heating system needs electricity, and an all-electric home has no backup at all when the power is out.
Large, old houses next to small new ones. Historic farmsteads like the Brinton-King Farmstead and the 1714 Barns-Brinton House share roads with condo buildings. Each needs very different heating work.
Heating problems seen most in Pennsbury
These are typical patterns for the township's housing, not records of specific calls.
Heat pumps running on backup strips
When a heat pump can't keep up in cold weather, electric strip heat takes over. Bills jump and the house may still feel cool. A low refrigerant charge, a failed defrost board or a dirty outdoor coil are common causes. See heat pump repair.
Iced-over outdoor units
Some frost is normal. A unit encased in ice, or one that never seems to defrost, needs service. Under trees, leaves and dripping branches make it worse.
Original ducts on new equipment
A modern heat pump on 1970s ductwork can be noisy, uneven and inefficient. Leaky ducts in crawl spaces and attics lose a lot of heat.
Oil burner lockouts and soot
Clogged nozzles and filters, failing fuel pumps and photocells cause most oil no-heat calls. Press the reset button once only. See oil furnace repair.
No heat after a storm
After an outage, systems may not restart cleanly, and power surges can damage control boards. Generators must run outside and connect through a proper transfer switch. More in power outages and heat.
Propane run-outs
About one in ten homes used propane in 2000. A tank that runs dry needs a leak check before relighting. See propane furnace repair.
Pennsbury villages, roads and landmarks covered
The whole township is covered, from Fairville near the Delaware line to Parkersville and Street Road in the northwest, and east to the Chadds Ford area along the Brandywine.

- Parkersville, home of the 1830 Parkersville Friends Meetinghouse off Street Road
- The Chadds Ford area in the township's east, part of the Chadds Ford census-designated place
- The Twin Bridges rural historic district near Brandywine Creek, listed in 2017

- The Barns-Brinton House on US 1, run as a museum by the Chadds Ford Historical Society, and the 54-acre township park
Pennsbury history that shapes heating today
Pennsbury stayed rural for most of its history. Its population nearly quadrupled between 1960 and 2000, so most homes date from a single era with its own heating habits.
- After 1700
Quaker farms on the Brandywine
Families including the Brintons, Harlans and Peirces settle farms along the west bank of the creek.
- 1714
Barns-Brinton House
William Barns builds a brick house and tavern on the Nottingham Road, now US 1.
- 1770
A township of its own
Pennsbury formally separates from Kennett Township.
- 1777
Battle of Brandywine
British troops advance through the valley; most fighting happens east of the creek.
- 1800s
Fairville and the meetinghouse
Fairville grows as a service village on the pike, and the Parkersville meetinghouse is built in 1830.
- 1960 to 2000
Suburban growth
Population grows from 936 to 3,500. Most homes get electric heat pumps, baseboard or oil.
- 2020
3,876 residents
Growth has slowed, and the township emphasizes open space and low density.
For heating, that history means most work in Pennsbury is on 1970s and 1980s houses with electric or oil systems, plus a small number of historic buildings. The old homes guide covers the latter.
What to expect when a heating company comes out
Pennsbury sits right next to East Marlborough, so it's close to Unionville. The challenge is less distance than narrow, wooded roads and driveways, especially after storms.
- From Unionville. Street Road (PA 926) runs east from the Unionville area into the township's northwest corner. Lenape Road (PA 52) and US 1 are the other main ways in.
- Driveways. Long or steep wooded driveways can be hard to reach after ice or a storm. Clear and salt the drive if you can, and mention it on the call.
- Downed trees. After a big storm, roads may be blocked. Expect delays until crews clear the roads and power is restored.
- Heat pump details. Note whether the outdoor unit is running, iced or silent, and whether the thermostat shows "aux" or "emergency" heat.
- Oil details. Read the tank gauge and note when the last delivery and cleaning were.
- Townhouses and condos. Know where your outdoor unit is and whether the association handles any equipment.
Pennsbury owner checklist
Built around the township's two big risks: aging electric and oil systems, and winter outages under the trees.
- Heat pump: keep the outdoor unit clear of leaves and 2 feet of space around it; check it after storms.
- Heat pump: learn your thermostat's "aux" and "emergency heat" settings, and don't leave emergency heat on.
- Oil: schedule yearly burner cleaning and keep the tank above a quarter.
- Outages: have a plan for heat if the power is out for a day; see the outage guide.
- Generator: outside only, far from windows and doors, with a transfer switch installed by a qualified electrician.
- CO alarms: on every level, with battery backup.
- Trees: report limbs on power lines to PECO.
Stop and call instead if
- You smell gas or propane. Leave and call 911 from outside.
- A CO alarm sounds, especially with a generator running.
- An oil burner won't stay lit after one reset. More presses can flood the chamber.
- You ran out of propane. It needs a leak check before relighting.
- Someone elderly or ill is in a cold house.
Electric, oil, gas and propane in Pennsbury
PECO is the electric utility for the township and supplies gas where mains reach. In 2000, only about one home in seven used utility gas. Most relied on electricity or oil, with propane in about one in ten. What you have depends on your street.

Pennsbury heating questions
Why is my electric bill so high in January?
Your heat pump may be leaning on electric backup strips. That happens in deep cold, but also when the heat pump is low on refrigerant, iced up or failing. If "aux" shows often in mild weather, have it checked.
Should I use emergency heat?
Only when the heat pump itself has failed and you're waiting for repair. Emergency heat runs the electric strips alone and is expensive. Normal backup heat switches on automatically when needed.
My outdoor unit is covered in ice. Is that normal?
Light frost that clears during defrost cycles is normal. A solid block of ice, or a unit that never defrosts, isn't. Turn it to emergency heat and call for service.
Is natural gas available in Pennsbury?
On some streets. In the 2000 census, only about 14% of homes used utility gas. Ask PECO with your exact address before planning a conversion.
What should I do when the power goes out in winter?
Close off unused rooms, keep doors shut and drip faucets on outside walls. Never use an oven, grill or indoor generator for heat. A generator must run outside with a proper transfer switch.
Is my oil tank too old?
Age alone doesn't decide it, but rust, weeping seams, wet spots or an oil smell around the tank are warning signs. Ask your oil company or technician to look at it during the yearly service.
Is my mailing address Chadds Ford or Kennett Square?
Many are Chadds Ford 19317, which the township's own office uses, but post office lines don't follow township borders. For a service call, give your street and nearest main road.
