Homes in Center City, and what heats and cools them

Society Hill has one of the largest concentrations of original 18th- and early 19th-century buildings in the country, mostly brick rowhouses of two to four stories in Federal and Georgian styles. Around Rittenhouse Square, most of the grand mansions gave way to condominium and co-op buildings after World War II, while Spruce Street keeps its brick and brownstone rows. Old City’s warehouses became lofts from the 1970s on, Washington Square West mixes rowhouses with condos and mid-rise apartments, and greater Center City has added more than 50,000 housing units since 1990.

  • Water-source heat pumps and fan coils

    Common in condo and apartment towers, where the equipment in each unit ties into a building water loop and the association runs the central boilers and cooling tower.

  • Through-wall PTAC units

    Packaged units under a window that heat and cool a single room. A replacement has to fit the existing wall sleeve and electrical supply.

  • Boilers and radiators

    Typical of rowhouses and brownstones built before forced air, with the boiler in the basement and cast-iron radiators on each floor.

Heating and AC service in Center City condos and towers

About 69,000 people lived in Center City at the 2020 census, and greater Center City has added more than 50,000 homes since 1990. Towers are part of that story, from Society Hill Towers, finished to I.M. Pei’s design in 1964, to the condominium and co-op buildings that replaced most of the mansions around Rittenhouse Square after World War II. In a condo tower, the equipment serving your unit is usually a water-source heat pump in a closet, a fan coil connected to the building’s hot and chilled water, or a through-wall unit under a window. The owner typically maintains that equipment while the association runs the boilers, cooling tower and piping. Some large downtown buildings take their heat from a 41-mile network of steam pipes under the streets, fed by a plant in Grays Ferry, and there the building’s engineers look after the supply side. Buildings often set rules for outside contractors, so check with the management office when you book a repair.

Boiler and furnace repair in Center City brownstones and rowhouses

Society Hill holds one of the largest collections of original 18th- and early 19th-century buildings in the country, mostly brick rowhouses of two to four stories. West of Broad Street, Spruce Street runs past brick and brownstone houses, among them a late 19th-century row of brownstones on the 1900 block, and Washington Square West mixes its rowhouses with condos and mid-rise apartments. Houses this old were built long before forced air, so they commonly heat with a gas boiler and radiators, or with a furnace fitted later into a tight basement. When one stops, we troubleshoot first, give you the price before any work begins, repair it the same day when we can and answer no-heat emergencies at any hour.

Cooling Old City lofts and historic homes

Old City was the city’s warehouse district. From the 1970s, artists and early residents turned its industrial buildings into homes with ceilings of 12 to 17 feet, and the Wireworks at 3rd and Race Streets became condominiums in the mid-1980s. In rooms that tall, warm air pools near the ceiling, so where the supply and return openings sit counts as much as the size of the equipment. In the rowhouses, a furnace fitted into the basement usually brings ductwork that can carry central air too, and if the house already has a high-velocity system, we can retrofit it with new equipment rather than cutting new chases through plaster. Society Hill and Old City are both on the Philadelphia Register of Historic Places, so new outdoor equipment there is reviewed by the Historical Commission as part of the permit.

Replacement and seasonal maintenance in Center City

When a heat pump, PTAC or boiler is near the end of its life, you see the replacement price next to the repair price before you decide. In a tower, a new unit has to match the closet, the wall sleeve or the water connections the old one used, so the model and size need confirming before anything is ordered. In a house, new systems can often go in the next day. Our $54 Seasonal Maintenance visit suits every kind of system downtown, since a clogged filter or a dirty coil costs far less to deal with in spring than during the first heat wave. Our shop in Bala Cynwyd is about seven miles from City Hall, a straight run down the Schuylkill Expressway.

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 Center City, Philadelphia, PA

Our condo has a heat pump in a closet. Do we call the building or an HVAC company?

Usually an HVAC company. In most condo towers the heat pump or fan coil serving your unit is yours to maintain, while the boilers, cooling tower and water loop belong to the association. Your condo documents spell out the split. Ask the management office about its rules for contractors, such as an insurance certificate or a booked service elevator, before the visit.

Can a through-wall PTAC unit be repaired, or does it need replacing?

Plenty of PTAC problems are repairable, such as a failed fan motor, a bad control board or a coil clogged with dust. When the compressor has failed on an older unit, replacement usually makes more sense, and the new unit must fit the existing wall sleeve and outlet. You get the price for either before any work starts.

We’re replacing the rooftop condenser on our Society Hill rowhouse. What approvals apply?

Replacing heating or cooling equipment in Philadelphia needs a mechanical permit from the Department of Licenses and Inspections, and a licensed contractor must do the work. Society Hill is on the Philadelphia Register of Historic Places, so the Historical Commission reviews new mechanical equipment as part of that permit, with photos showing how visible the work is from the street. Window air conditioners that don’t alter the windows are exempt.

Our Old City loft has very high ceilings and never feels comfortable. What helps?

In a tall room, warm air collects near the ceiling, so a loft can feel chilly at floor level in winter and stuffy up high in summer. Returns placed low, supply outlets aimed at the living space and ceiling fans that push warm air back down all help. If the ductwork was laid out for an open floor that has since been divided, rebalancing or adding a zone can even it out.
