Old City is one of the oldest residential neighborhoods in America — and the HVAC systems inside these homes reflect that. Homes along Elfreth's Alley, Race Street, Arch Street, and throughout the historic grid were built in an era long before central air conditioning existed. The defining challenge for any HVAC contractor working here is the same: beautiful, historically significant homes that have no ductwork and weren't designed around modern HVAC systems.
The single best upgrade we can install in most Old City homes is a ductless mini-split heat pump. A Mitsubishi or Fujitsu system requires only a 3-inch penetration through an exterior wall for the refrigerant line — no dropped ceilings, no ductwork ripped through your home, no major construction. A single-zone system handles a floor or a large open-plan space. Multi-zone systems let you control individual rooms and floors independently from the same outdoor unit. And because heat pumps both heat and cool, you're replacing or supplementing your heating system at the same time.
For converted warehouse condos — common in Old City between Front Street and 5th Street — we often install multi-zone systems that give owners independent climate control in bedroom and living areas. These buildings can have challenging condenser placement due to historic preservation guidelines and rooftop access restrictions; we work with building management to find compliant placement before any install begins.
A significant number of older Old City homes — particularly the pre-war row houses — were originally heated by steam boilers. These systems push steam through radiators throughout the home and have been working reliably for decades, but they're not immortal. Common issues include banging pipes, uneven heat distribution, failed zone valves, and eventually the boiler itself reaching end of life.
When a boiler in an Old City home fails, there are two paths: replace the boiler in kind with a modern high-efficiency unit, or use the opportunity to transition to a ductless heat pump for both heating and cooling. Which makes sense depends on the age and condition of your radiator system, your budget, and how long you plan to stay in the home. We assess each situation honestly and give you the numbers, not the upsell.

📞 (215) 379-2800Yes — and it's usually the best option. Most pre-war row houses in Old City have no ductwork, making traditional central AC highly invasive to install. A Mitsubishi or Fujitsu ductless mini-split provides efficient heating and cooling with just a small wall penetration. We can cool a single room or zone an entire multi-story home.
Yes. Many Old City homes have steam boilers or hot water boiler systems. We repair and maintain these and replace them with high-efficiency alternatives when needed. We also do 24/7 emergency boiler service — if you lose heat, call (215) 379-2800.
A ductless mini-split heat pump is the cleanest solution. We mount a wall-mounted air handler indoors, run a refrigerant line through a 3-inch hole to an outdoor condenser, and you have both heating and cooling. Multi-zone systems give you independent floor-by-floor control. Far less invasive than adding ductwork, and modern units are quiet and energy-efficient.
Yes. We work in converted warehouse condos and multi-unit buildings in Old City regularly. We coordinate with building management when needed and are familiar with the condenser placement restrictions common in historic properties. Call us to discuss your specific building.
For homes without ductwork, ductless mini-splits are the most practical and efficient option — minimal renovation required. For homes with working radiator systems, keeping the boiler for heat and adding a ductless system for cooling is often the most cost-effective approach. We assess each home and recommend what actually makes sense.
Our headquarters is in Huntingdon Valley, about 20–25 minutes from Old City in normal traffic. We provide 24/7 emergency service with no after-hours surcharges for maintenance plan members. Call (215) 379-2800 any time.

"McCorry installed a Mitsubishi mini-split in our Old City row house. No ductwork, minimal disruption, and the system is incredibly quiet. Wish we'd done it years ago."
"Our boiler died on a Friday night in January. McCorry had a tech at our door within 2 hours. They had the part on the truck and we had heat back the same night."
"Very professional. They assessed our historic condo building, worked with our building manager on condenser placement, and the install was clean and fast."
