Air conditioning
Humid July nights, an upstairs bedroom that never cools, or an old condenser that finally quit. We repair and install central AC and ductless systems, sized for your house and how you actually live in it.
01AC repair
Check the thermostat is on Cool, the filter isn't clogged, and both breakers (indoor and outdoor) are on. If you see ice, turn the system off and switch the fan to On to let it thaw.
02Central AC replacement
We size new systems with a load calculation, not by copying the old unit. Too big, and it cools fast but leaves the air damp and clammy. Too small, and it runs all day in a heat wave. Your written quote includes the equipment, line set, pad or roof stand, electrical disconnect, permit and haul-away.
We'll also look at your ductwork. In a lot of older homes, ducts added decades later in attics or closets are the real reason the second floor is hot.
03Ductless mini-splits
No ductwork? Ductless systems run small refrigerant lines from an outdoor unit to quiet wall-mounted heads in the rooms that need them. Most also heat.
We plan head placement and line routing with you, so the outside looks tidy and the inside doesn't look like an afterthought.

Valley neighborhoods along the rivers hold heat and humidity, and hilltop houses get full afternoon sun. Many older homes have attic-mounted air handlers added later, and condensers squeezed onto a narrow side yard or a hillside pad. We make sure the pad is level and the unit has room to breathe.

Rowhouse condensers often sit on the flat roof, which gets brutally hot in summer. We check roof stands, line set insulation and roof penetrations, and we're careful with the roofing. Shared walls help in winter, but the top floor of a rowhouse can bake in a heat wave. Philadelphia crew
06AC questions
If the system is under about ten years old and the repair is a part like a capacitor, motor or contactor, repair usually makes sense. If it's older, uses an outdated refrigerant, or has a major leak or compressor failure, replacing is often smarter. We'll give you prices for both so you can compare.
Yes. Your options are a ducted system with an air handler in the attic and ducts run through closets, or ductless mini-splits in the rooms that need cooling. In rowhouses and older homes with plaster walls, ductless is usually less disruptive. We'll walk the house with you and price both.
Usually the condensate drain is clogged with algae or debris, so water backs up and overflows the drain pan. A failed condensate pump or a frozen coil can also cause it. Turn the system off to limit damage and call us. Clearing the drain is a quick fix, and we'll add a safety switch if it's missing.
