24/7 + HVAC + HOT WATER = McCORRY COMFORT
New central air, ductless mini-split, or heat pump installation throughout Philadelphia, Montgomery County, Bucks County, and Delaware County. Properly sized, professionally installed, backed by 25 years of local experience.
Every installation starts with a Manual J load calculation — the only accurate way to size a system for your home. Oversized and undersized units both fail prematurely and cost more to run.
The most common installation for Philadelphia-area homes with existing ductwork. We install the outdoor condenser, indoor air handler or coil, and connect to your existing forced-air system. Sized right for your home's actual load.
Schedule a quote →No ductwork required. Ideal for additions, older homes, converted spaces, or any room where extending ducts isn't practical. Single-zone and multi-zone systems available. Mitsubishi and Fujitsu are our primary brands.
Schedule a quote →One system for both heating and cooling. Modern heat pumps work efficiently in Philadelphia winters. Great for homes replacing older AC + electric heat, or for efficiency-focused upgrades. We install both ducted and ductless heat pumps.
Schedule a quote →Replacing everything — furnace, AC, and coil — at once? Combined installs save on labor and are the most efficient path to a high-performing, matched system. We'll spec out the right combination for your home.

We recommend the right system for your home, your budget, and your efficiency goals. We'll explain the options — no pressure.
Most central air installs are completed in one day. Our crew handles everything — equipment, electrical connections, refrigerant charge, and testing.
We start up the system, verify performance, and walk you through thermostat operation and filter maintenance before we leave.
We recommend based on your home's needs and long-term reliability — not on margin. Ask us which system we'd put in our own home.
"McCorry installed a new Carrier central air system in our 1960s split-level. They sized it properly, didn't oversell us on tonnage, and the whole job was done in one day. House is cooling evenly for the first time ever."
"Had a ductless mini-split put in the addition on our house. No ductwork was possible. McCorry recommended the right Mitsubishi unit, installed it cleanly, and it's been flawless. Highly recommend."
"Very professional from quote to installation. They explained why the old unit was oversized and what the right size was for our square footage. Noticeably more efficient now."
Standard central air: one day. Single-zone ductless mini-split: 4–6 hours. Multi-zone or new ductwork: 2–3 days. We'll give you an accurate timeline when we assess your home.
Depends on square footage, insulation, windows, ceiling height, and sun exposure — not just square footage alone. We do a Manual J load calc on every job. A 1,500 sq ft home in Philadelphia may need a different size than the same house two miles away depending on the build.
If you have forced-air heat (furnace), central AC ties right into it. No ductwork? A ductless mini-split system is the clean solution — no major construction required.
Carrier, Trane, Lennox, Mitsubishi, Fujitsu, Daikin, Bosch, and York. We'll recommend the right brand and model for your situation — not the one with the highest margin.

Yes. Replacement swaps out an existing system — typically faster and less involved. New installation may require more electrical work, refrigerant line runs, and potentially ductwork. See our AC replacement page →
