Short answer
We repair, replace and maintain heating and cooling systems in Philadelphia, PA and South Jersey: gas furnaces, hot-water and steam boilers, central air, heat pumps and ductless units, plus ductwork, water heaters, related home repairs and commercial rooftop units, walk-ins and boilers. The phone is answered 24 hours a day.
Which of these do you actually need?
Start with what the house is doing, not the name of the part. These are the most common starting points:
- No heat or no cooling right now: 24/7 Emergency HVAC Repair
- A furnace that runs but the house stays cold: Furnace Repair
- Radiators that bang, hiss or stay cold: Steam Heat Repair
- Central air blowing warm or icing up: AC Repair
- A top floor that will not cool down: Ductless Mini-Split Installation
- One floor hot, another cold: HVAC Zoning Systems
- No hot water or water around the tank: Water Heater Repair
- A restaurant walk-in losing temperature: Walk-In Cooler & Freezer Repair
If none of these fit, call and describe it. Most of the time the tech can tell from a two-minute conversation which visit to book.
Furnaces, boilers, steam and radiators
Heating
Older Philadelphia houses heat with almost everything: gas furnaces, cast iron hot-water boilers, one-pipe steam, and radiators that have outlived several boilers. Heating repairs start with finding where the system's sequence stops, and replacements start with sizing the new equipment to the house rather than to the old unit.
24/7 Emergency HVAC Repair
No heat, no cooling or a leaking boiler at night. Call any hour.
Furnace Repair
Gas furnaces that blow cold, short cycle or will not light.
Furnace Replacement & Installation
New gas furnaces sized for the house, not the old unit.
Boiler Repair
Hot-water boilers that lock out, leak or leave rooms cold.
Boiler Replacement
Condensing, combi and steam boilers for older homes.
Steam Heat Repair
Banging pipes, cold radiators and steam boilers that cut out.
Radiator & Baseboard Repair
Cold radiators, leaking valves and tired baseboard loops.
Furnace & Boiler Tune-Up
A fall visit that catches the cheap problems first.
Oil to Gas Conversion
Switching an oil boiler or furnace over to natural gas.
Central air, coils, compressors and small-duct systems
Cooling
Most cooling calls in rowhomes come down to a tired outdoor unit on a flat roof, an indoor coil starved for air, or a slow refrigerant leak. For houses that never had ducts, high-velocity systems run small tubing through closets and walls instead of full-size ductwork.
AC Repair
Central air that runs warm, freezes up or will not start.
Central AC Installation & Replacement
New central air systems matched to the ducts you have.
AC Tune-Up
Spring cleaning and checks before the first hot week.
AC Refrigerant Leak Repair
Finding the leak before anyone adds refrigerant.
AC Compressor Replacement
When the compressor fails, and when it is worth replacing.
Evaporator Coil Replacement
Leaking or rotted indoor coils swapped and matched.
High-Velocity Central Air
Small-duct central air for plaster-wall homes without ducts.
One outdoor unit for heat and cooling, and wall units where ducts never reach
Heat Pumps & Ductless
Heat pumps move heat instead of burning fuel, and ductless heads cool or heat single rooms like a hot third floor, an addition or a finished basement. They need clean filters and coils to keep their capacity, which is where cleaning visits come in.
Heat Pump Repair
Heat pumps stuck in defrost, blowing cool or running nonstop.
Heat Pump Installation
Cold-climate and dual-fuel heat pumps for local winters.
Ductless Mini-Split Installation
Wall units for hot third floors, additions and basements.
Ductless Mini-Split Repair
Error codes, dripping heads and units that stopped cooling.
Ductless Mini-Split Cleaning
Blower wheel and coil cleaning for musty, weak heads.
Ductwork, thermostats, zoning, humidity and filtration
Ducts & Indoor Air
The equipment is only half of comfort; the air has to get to the rooms. This group covers the ducts themselves, the controls that decide which floor gets air, and the add-ons that manage humidity and filtration through the same system.
Air Duct Cleaning
Supply and return cleaning after renovation dust or years of use.
Ductwork Installation & Replacement
New runs, returns and trunk lines for older homes.
Duct Sealing & Repair
Disconnected, leaking and uninsulated duct runs fixed.
Smart Thermostat Installation
Wi-Fi thermostats wired right for furnaces, boilers and heat pumps.
HVAC Zoning Systems
Separate control for the floor that is always too hot or cold.
Whole-House Dehumidifier Installation
Damp basements and clammy summer air pulled down.
Whole-House Humidifier Installation
Moisture back into dry winter air from forced-air heat.
Air Filtration & UV Purification
Media filters, UV lights and air cleaners on the system.
Water heaters and the repairs that come up around them
Water Heaters & Home Repairs
The water heater usually sits beside the furnace or boiler, and it shares a flue, a gas line and sometimes a problem with it. We also handle the home repairs that follow HVAC work or tend to come up on the same visit: vents, exhaust fans, liners, gas lines, insulation, ceiling fans and drywall.
Water Heater Repair
No hot water, a pilot that will not stay lit or a leak.
Water Heater Replacement
Gas, electric and power-vent tanks swapped and hauled away.
Tankless Water Heater Installation
Tankless units with the gas line and venting done right.
Dryer Vent Cleaning
Lint cleared from long vent runs and roof exits.
Bathroom Exhaust Fan Installation
Quiet fans vented outside so bathrooms dry out.
Chimney Liner Installation
Liners for gas furnaces, boilers and water heaters.
Gas Line Installation & Repair
New gas runs for ranges, dryers and grills, and leak repair.
Attic Insulation
Blown-in insulation and air sealing above the top floor.
Drywall & Plaster Repair
Patches after leaks, new vents and old plaster cracks.
Ceiling Fan Installation
Fans hung on fan-rated boxes, swapped for old light fixtures.
Rooftop units, walk-ins and boilers for businesses
