Homes in Wynnefield, and what heats and cools them

Thomas Wynne built Wynnestay in 1689, and the house was renovated in 1904 and listed on the National Register in 2008. Most of Wynnefield stayed farmland until the Market-Frankford Elevated and the trolley lines made it practical to live this far out. The early twentieth century brought large stone homes faced in a heavy gray stone called Wissahickon schist. In the 1920s rural lots were divided into smaller blocks of row houses and Diamond Street was laid out in 1923. Many of the newer houses were built with rear alleys and garages. Today the 19131 ZIP mixes two-story brick town homes and row duplexes with garden, mid-rise and high-rise apartments.

  • Boilers and radiators

    Houses from the early twentieth century were commonly built around a boiler. Where the radiators remain, a cold room usually traces back to trapped air, a stuck vent or a tired circulator.

  • Outdoor units off the rear alley

    On rowhouses and twins built with a rear alley, the back of the lot is usually the practical place for a condenser, and the alley gives a path in for service.

  • Separate systems in row duplexes

    A duplex with one apartment above another often has a separate furnace or boiler for each unit, so each one needs its own look at tune-up time.

Stone houses on old farmland

For most of its history Wynnefield was farmland. The best-known survivor from those years is Wynnestay, which Thomas Wynne built in 1689 and which still stands on Woodbine Avenue. The neighborhood itself arrived with the elevated train and the trolleys, and the first wave of it was built in stone. Much like Chestnut Hill and Mount Airy, early Wynnefield was defined by heavy gray Wissahickon schist, and a lot of those houses are still here.

Stone houses of that age were generally built to be heated by a boiler, with radiators under the windows. If yours still works that way, it is worth keeping in good order rather than written off. A boiler that short-cycles, a radiator that stays cold or a pipe that knocks usually has one cause, and finding that cause is where we start. You hear the price before any work begins.

Cooling behind walls of schist

Air conditioning is the harder problem, since running ductwork in a stone house means cutting chases through plaster and finding room in closets, and the thick exterior walls leave little space to hide anything. If the attic has headroom, a compact air handler can be tucked up there to cool the bedrooms, and the rooms below stay on their radiators.

Rowhouses, twins and the alley out back

The 1920s changed Wynnefield’s streets. Rural lots were split into smaller parcels for rows of houses and Diamond Street went in during 1923. Many of the new houses came with rear alleys and garages. Twins were popular with upper-middle-class families.

That layout shapes where heating and cooling equipment can go. A rowhouse has neighbors on both sides, so the rear of the lot or a flat roof is usually the only place for an outdoor unit, and the alley is the easiest way to reach it. On a twin, each half normally has its own system, and a new condenser belongs on your side of the property with enough clearance to breathe. Row duplexes, with one apartment stacked on another, often have two of everything.

What customers say

Saki of SK Heating and Air Conditioning has been servicing my HVAC system for the past 4-5 years. He is always prompt, neat, polite, and professional and I really like the convenience of communicating by text. One thing that sets SK apart from other service companies is that he has never attempted to sell me anything I didn’t need. I can’t recommend Saki enough.

FAQs about HVAC services in Wynnefield, Philadelphia, PA

Our stone house has radiators and no ducts. How can we add air conditioning?

The attic is usually the place to start. If it has headroom, a compact air handler can sit up there and cool the bedrooms through short duct runs, while the rooms below keep their radiators. Taking ducts down to the first floor means cutting chases through plaster and borrowing closet space, so we look at the house before suggesting how far to go.

Do I need a permit to replace my furnace or boiler in Wynnefield?

Yes. In Philadelphia, installing heating and cooling equipment takes a Mechanical Permit from the Department of Licenses and Inspections. Replacing an appliance in a one- or two-family house qualifies for an EZ permit, which needs no drawings, and the work has to be done by a licensed contractor. Routine repairs and upkeep are exempt.

Who supplies gas and electricity in Wynnefield?

Philadelphia Gas Works (PGW) supplies natural gas inside the city, and PECO supplies electricity. If you ever smell gas, PGW says to leave the house first and then call them at 215-235-1212 from a safe place. Once the gas side is safe, we can look at the furnace or boiler.
