Choose Your Air Conditioning Service

AC Repair

Your system is blowing warm air, leaking water, freezing up, tripping a breaker, or not starting at all. A technician finds the cause and gives you the repair price before any work begins.

AC Installation

You are adding central air or ductless cooling to a home that does not have it. We assess the house, the ductwork, and the electrical supply before we recommend equipment.

AC Replacement

Your current system is aging or costly to keep running. We compare repair and replacement costs with you and size the new system to your home.

AC Maintenance

Your system works, and you want it checked before summer. A spring tune-up looks at airflow, drainage, coils, electrical parts, and cooling performance while small problems are still easy to fix.

Signs Your Air Conditioner Needs Service

Call for service when your system stops keeping the house comfortable or shows any of these signs. Philadelphia summers bring long stretches of heat and humidity, so small problems tend to show up fast.

  • Warm air from the vents. Causes can include airflow problems, electrical failures, refrigerant loss, or compressor-related issues.
  • Ice on the indoor coil or copper lines. Turn the system off and schedule service rather than continuing to run a frozen system.
  • Water near the indoor unit. A drain, pump, frozen coil, or pan problem may be involved.
  • A house that feels cool but damp. Short run times, airflow problems, or improper sizing may reduce dehumidification.
  • Upper floors that never cool. Ductwork, airflow, solar gain, or system sizing may all contribute.
  • New noises, repeated breaker trips, or a hot electrical smell. Shut the system down and request service rather than repeatedly resetting a breaker.

How We Size an Air Conditioner

We size every new system with a load calculation, not the size of the old unit or the square footage alone. The calculation accounts for insulation, windows, sun exposure, ceiling height, and how air moves between floors.

A system that is too large cools the house quickly and shuts off before it removes much moisture. A system that is too small runs constantly on the hottest days. Two homes of the same size on the same Philadelphia block can need different equipment.

Central Air, Ductless, and Heat Pump Options

The right cooling approach depends on the home. Central air uses ductwork to cool the whole house. Ductless mini-splits serve rooms or zones without conventional ductwork. Heat pumps provide both heating and cooling with one system.

In rowhomes and older houses built for radiator heat, ductless is often the simplest way to add cooling without opening walls and ceilings. When an aging central air conditioner needs replacing, many homeowners choose a heat pump instead and keep their gas furnace as backup for the coldest days.

Air Conditioning Across Philadelphia and Nearby Communities

W.F. Smith serves Philadelphia and nearby communities across Bucks and Montgomery Counties. City homes can present access, ductwork, rooftop-equipment, and top-floor comfort challenges, so the service or estimate starts with the actual layout and equipment in the home.

Our Philadelphia HVAC service page covers rowhome cooling, rooftop condensers, and the city neighborhoods our crews work in most.

Air Conditioning Questions From Philadelphia Homeowners

Who repairs, installs, replaces, and maintains air conditioners in Philadelphia?

W.F. Smith, a family-owned heating and cooling company on State Road in Northeast Philadelphia, has worked on home air conditioning since 1946. We repair, install, replace, and maintain central air, ductless mini-splits, and heat pumps across Philadelphia and nearby Bucks and Montgomery County communities. The company holds Pennsylvania Home Improvement Contractor license PA003700.
Switch the system off at the thermostat if you see ice, smell burning, or the breaker trips, and then call for service. During office hours, Monday through Friday from 8:00 a.m. to 4:00 p.m., the office books the repair. After hours, an answering service reaches the on-call technician, who quotes the after-hours rate before coming out.
The right size comes from a room-by-room load calculation done in your home, not from the old unit’s size. Two houses with the same square footage can need different equipment once insulation, windows, and sun exposure are counted. A system that is too big shuts off before it dries the air. A system that is too small runs nonstop in July and still falls behind.
Most of the new cooling systems we install are Lennox or Mitsubishi Electric, and Mitsubishi Electric is the brand we install most often for ductless. Our technicians also repair other major brands. You can book an AC repair with W.F. Smith no matter who made your equipment or who installed it.
No. Estimates for new and replacement cooling systems are free. We visit the home, measure it, and give you written options before you decide anything. Repair visits work differently. The office tells you the visit fee when you book, so you know that cost before a technician comes out.

Yes. Along with homes, W.F. Smith installs and services cooling for offices, restaurants, and apartment buildings, including rooftop units and VRF systems. Commercial projects are planned around how the building is used and when the work can happen with the least disruption. Our Commercial AC page explains how those jobs are handled.
