AC Replacement in Philadelphia | Free Estimates

Replace Your Air Conditioner With Confidence

W.F. Smith replaces central air conditioners for homes across Philadelphia and nearby Bucks and Montgomery County communities. We size each new system for the home as it is today instead of copying the old equipment.

If repair is still the better choice, we tell you. If replacement makes more sense, the free estimate explains the new system and every part of the work needed to install it.

When to Consider Replacing Your AC

A major part, such as the compressor or indoor coil, has failed on a system that is already well into its service life.
Repair visits are coming more often each summer.
The system uses R-22 refrigerant, which has not been produced in the U.S. since 2020.
Some rooms never cool, or the house stays humid, and the current system has never fixed it.
You are replacing the furnace, or considering a heat pump, and want the new equipment matched.

Repair or Replace: How We Help You Decide

A replacement decision should consider more than the age of the equipment. The technician can explain the failed component, the condition of the rest of the system, the repair cost, and whether other major components are likely to need attention soon.

When you want to compare both paths, W.F. Smith can provide the repair option and a replacement estimate so you can make the decision with the full picture.

Most central air conditioners give 15 to 20 years of service. A small repair can make sense at almost any age. A compressor or coil failure late in that window usually tips the math toward replacement.

What an AC Replacement Includes

A load calculation, so the new system fits the house you have now, including any insulation, window, or layout changes since the old unit went in.
An outdoor unit and indoor coil rated to work together, with matching refrigerant.
A check of the ductwork, airflow, electrical service, condensate drain, and access.

Removal of the old equipment, with its refrigerant recovered as federal rules require.
Startup, performance testing, thermostat setup, and equipment warranty registration.

Why Replacing Only the Outdoor Unit Rarely Works Now

A new outdoor unit has to match the indoor coil, the blower in your furnace or air handler, the thermostat, and the refrigerant. Under EPA rules, new central air conditioners built since January 1, 2025 use lower-impact refrigerants such as R-454B or R-32 instead of R-410A.

Those newer refrigerants need a compatible indoor coil. A mismatched pair can cool poorly, wear out early, and may not be covered by the manufacturer’s warranty. That is why most replacements today include the indoor coil, and why we check the coil, furnace, and controls before quoting.

Heat Pump or Air Conditioner?

When an air conditioner wears out, a heat pump is worth pricing alongside it. A heat pump cools exactly like central air in summer and also heats the house in spring, fall, and much of the winter.

Many homeowners keep their gas furnace and pair it with the heat pump in a dual-fuel system. The heat pump handles mild weather, and the furnace takes over on the coldest days. Your free estimate can include both options side by side.

What Affects AC Replacement Cost?

Capacity, efficiency rating, and single-stage, two-stage, or variable-speed operation.
Whether the ductwork needs repair or resizing.
Electrical updates for the new equipment.
Access, such as a rooftop condenser on a rowhome or an attic air handler.
Whether the indoor coil, furnace, or air handler is replaced at the same time.

Every new split air conditioner installed in Pennsylvania must meet the federal minimum of 13.4 SEER2, a standard that took effect in 2023. Higher-efficiency models cost more up front and less to run each summer.

Current rebates and specials are listed on our Specials page, and financing is available on new systems. Programs change during the year, so your written proposal names any offer that applies to the equipment you choose.

How AC Replacement Works

A free in-home visit to look at the current system, the ductwork, and the house.
A load calculation and a compatibility check of the indoor coil, furnace or air handler, and electrical service.
A written proposal with the recommended equipment and the full scope of work.
Removal of the old system and its refrigerant, then installation of the new equipment. The old refrigerant lines stay only if they are the right size and in good condition.
Startup, performance checks, thermostat setup, and warranty registration.

Protect the New System With Preventive Maintenance

A tune-up each spring keeps the new coil clean and the drain clear, and it gives you a yearly record of how the system runs. Homeowners who want ongoing service through one program can join the W.F. Smith Maintenance Plan, and plan members get priority when they need emergency service.

AC Replacement Questions From Philadelphia Homeowners

How long do air conditioners last?

Most central air conditioners last about 15 to 20 years. Condition matters more than age, though. A 16-year-old system with a clean repair history may have years left, while a 10-year-old unit with a leaking coil may not be worth fixing. Regular maintenance, correct sizing, and good installation all push a system toward the long end of that range.

Can I replace only the outdoor unit?

Sometimes, but far less often than before. The outdoor unit must match the indoor coil and use the same refrigerant. New outdoor units built since 2025 use newer refrigerants that need a compatible coil, so pairing one with an old coil rarely works. We check the age and type of your coil before quoting an outdoor-only replacement.

Should I replace the furnace at the same time?

It often makes sense when the furnace is also near the end of its life or cannot move enough air for the new AC. Doing both at once means one installation, matched equipment, and warranties that start on the same day. If the furnace is newer and in good shape, we replace only the air conditioner. The estimate can price both options.

Is a heat pump a good replacement for central air in Philadelphia?

For many homes, yes. A heat pump replaces the outdoor air conditioner and also heats the house, which can reduce how much gas the furnace burns. Paired with your existing gas furnace in a dual-fuel setup, the furnace still handles the coldest days. Your free estimate can price a new air conditioner and a heat pump side by side.

Are rebates or financing available?

Often, but the programs change. Rebates can come from utilities, equipment manufacturers, and government programs, and each has its own dates and rules. Our Specials page lists current offers, and financing is available on new systems. Your written proposal names any rebate or offer that applies to the equipment you choose.

What happens to my old air conditioner?

We remove it as part of the job. Before the old unit is disconnected, its refrigerant is recovered with certified equipment, as federal rules require, so it is not released into the air. The old equipment then leaves with our crew, and you do not have to arrange disposal.

Compare Your Options Before You Decide

Request a replacement estimate if your current system is becoming unreliable or a major repair has prompted you to compare both paths.
