AC Installation and Replacement in Easton, PA

Replacing an air conditioner is the second most expensive thing most homeowners buy for their house, and it is the one they have the least information about. This page explains how we size, price and install a system in Easton and the Lehigh Valley, and what separates a good installation from a cheap one.

The install matters more than the brand

A correctly sized mid range system installed properly will outperform a premium system installed badly, every time. The failures we get called to fix on other companies’ installations are almost always the same three things: a system sized by rule of thumb instead of by calculation, ductwork that cannot carry the airflow the equipment needs, and a refrigerant charge that was never properly set.

Sizing is a calculation, not a guess

Bigger is not better with air conditioning. An oversized system cools the air quickly, satisfies the thermostat, and shuts off before it has removed the humidity. The result is a house that feels cold and clammy, and a compressor that wears out early from short cycling.

Sizing depends on the square footage, the insulation, the windows and which way they face, the ceiling heights, the ductwork and how airtight the house is. In an area like Easton with a lot of older housing stock, two houses of identical size can need genuinely different systems.

What a replacement includes

• An assessment of the existing ductwork, because new equipment on undersized ducts will underperform from day one
• Correct sizing for your house rather than a match to whatever was there before
• Removal and responsible disposal of the old equipment and its refrigerant
• New line set or a proper flush of the existing one
• A new condensate drain and safety switch
• Refrigerant charge set and verified against the manufacturer’s specification
• Airflow measured and adjusted
• Thermostat setup, and a walk through with you before we leave

What it costs

We are not going to publish a single number for a system replacement, because anyone who does is quoting a job they have not seen. The price depends on the size, the efficiency you choose, the condition of your ductwork and how accessible the equipment is.

What we will tell you: you get a written quote after we have looked at the house, and it will separate the equipment from the labour so you can see what you are paying for. Financing is available through Wisetack from $500 to $65,000, with approved applicants able to spread the cost.

Our published fees for diagnostic and service work are on our pricing page.

Should you replace the furnace at the same time

If your furnace and air conditioner share ductwork and a blower, and both are near the end of their lives, replacing them together usually costs less than two separate jobs and it guarantees the two halves are matched. If your furnace has years left, we will say so rather than sell you one.

Repair or replace

Replacement is usually the right answer when the system is past twelve to fifteen years, when it uses R22 refrigerant that has been phased out, or when a major component like the compressor has failed. If none of those are true, see AC repair instead.

Common questions

How long does an air conditioner installation take?

A straightforward changeout is usually a single day. Jobs that involve ductwork changes, electrical work or difficult access take longer, and we will tell you which yours is before we start.

How long should a new system last?

Twelve to fifteen years is normal, and longer with annual maintenance. Systems that fail early are usually oversized, poorly charged, or never serviced.

What efficiency rating should I buy?

Higher efficiency costs more upfront and saves more each month, so the answer depends on how long you plan to stay in the house. We will show you the difference in running cost rather than just pointing at the more expensive box.

Do I have to replace the ductwork too?

Usually not, but it has to be assessed. Undersized or leaking ducts will strangle a new system and you will have paid for capacity you never receive.

Can you install a system I bought myself?

Ask us. Manufacturer warranties frequently depend on who supplied and installed the equipment, and we will explain what you would be giving up before you commit.
