    Compressor Pricing by Size of AC

    Bigger AC units need more powerful compressors, which cost more. Apart from the size, the cooling capacity also hugely impacts the cost. In HVAC, cooling power is measured in tons.

    (1 ton=12,000 BTUs). So, higher tonnage means a higher price.

    Here's an average estimate of what you can expect to pay based on different sizes of AC Compressor:

    SIZE COST
    1.5 - 2 ton unit $700 to $1,400
    2.5 - 3 ton units $900 to $2,100
    3.5 - 4 ton units $1,100 to $2,100

    ​Compressor Cost by Its Type

    Reciprocating Compressors

    Generally, the price range is $400 -$1000 for reciprocating compressors. These compressors are strong and durable, but louder and less efficient. "It is used for residential as well commercial purposes.”​

    Rotary Compressors

    Generally, the price range of rotary compressors is between $50-$100 per unit. This is the cheapest and most efficient option for small AC units.

    Scroll Compressors

    Scroll compressors generally range from $500-$1500. They are quiet, efficient, and ideal for most homes.

    Variable Speed Compressors

    They usually range between $1,500 to $2,800. These compressors cut energy use by 30%-40% , and hence, are considered highly efficient.

    Compressor Cost in a Nutshell

    TYPE COST RANGE BEST FOR
    Reciprocating $400 -$1000 Residential As Well Commercial Purposes
    Rotatory $50-$100 Basic Efficiency
    Scroll $500-$1500 Quiet, efficient and ideal for most homes
    Variable Speed $1,500 - $2,800 Highly Efficient

    ​AC Compressor Cost by Air Conditioner Type

    Window AC

    Compressors for window AC units can cost between $150 and $700, which is also the cost of  buying a brand-new Window AC, so it's better to replace the whole unit if the compressor stops working.​

    Mini-Split

    The average cost to replace a mini-split AC compressor is between $600 and $2,200. This pricing includes labor charges as well as parts. For larger units, it’s better to replace the entire mini-split system rather than just changing the compressor.

    Central Air

    You can expect to pay between $800 and $3,000 on average for a central AC compressor replacement. Whereas, the cost of installing a new system ranges between $3080 and $5965. Hence, replacing the compressor is a smart option.

    Heat Pump

    The average cost for a heat pump compressor replacement lies between $800 and $3,000. These air conditioning systems are expensive to install, so it would be best to replace the compressor.

    Window AC $150 - $700
    Mini-Split $600 - $2,200
    Central- Air $800 - $3,000
    Heat Pump $800 and $3,000

    Bundle Repairs Together

    If your AC needs other repairs too, get all repairs done together because companies often give small discounts when you bundle services.

    Use Tax Credits

    You may get up to 30% back on HVAC upgrades through the Energy Efficiency Home Improvement Credit. Your local company may also offer rebates.

    Ask About Financing

    Some HVAC companies offer 0% financing for 12-18 months. You just need to make sure that you can pay it off within the promotional period. Credit unions may also give cheaper HVAC loans.

    Keep Safe Warranty

    Do regular maintenance and use licensed technicians. Skipping maintenance or using unlicensed workers can cancel your warranty and cost you more.

    Buy at the Right Time

    Consider replacing your compressor in the off-season, like in the late fall or early spring. Companies are less busy at that time and often give discounts.

    On average, an AC Compressor can last for about 12 to 15 years. However, its life depends on how well you maintain your AC, and things like regular servicing, right refrigerant levels, and not overloading the system play a vital role . A compressor usually stops working early because of overheating, refrigerant leak, or electrical problems. Getting your AC checked once a year can help it last longer.

    When Should You Repair Your AC Compressor?

    • When you find electrical problems like faulty capacitors or contractors.

    • If the small refrigerant leaks.

    • When you find inefficient cooling, it might just need more refrigerant or a good cleaning to start working properly again.

    • If you hear an unusual noise coming from your AC.

    When Should You Replace a Compressor?

    • You should replace your AC compressor when repair keeps failing, cooling becomes very weak, or the unit makes unusual or loud noises.

    • If the compressor has major electrical damage, or if it is 10-12 years old and has gone through refrigerant leaks, replacement is a smarter choice than repairing.

    Conclusion

    The price of a compressor varies depending on AC type, brand, etc. Knowing how much an AC compressor costs helps you make a vital decision when the compressor stops functioning. It helps you decide whether to replace the entire unit or just repair the non-functional compressor.
