Factors that affect central air conditioner prices

Several factors could affect the price of a central air conditioner. Some of these factors include the size of the unit, the type of home you have, the size of your home, the cost of professional installation, advanced features it might come with and whether you have an existing HVAC system already in place.

Size of unit and type of home

Installation costs can vary depending on how large or small the unit is as well as the type of home you have. Modern homes typically make installation easier and cheaper. Air conditioning units come in different sizes, shapes, energy efficiency ratings and cooling capacities. The type of unit you choose has a direct impact on installation costs.

Size of home

The larger your home, the larger the unit you’ll need to cool your home efficiently. As you may have guessed, larger units generally cost more to install than smaller units because of the amount of labor involved.

Professional installation

Professional installation costs can tack on thousands of dollars to the overall price of your new central air conditioning system. Be sure to factor in installation when calculating your budget for your new central air conditioner.

Advanced features

Better brands of central air conditioners generally come with smarter technology. With these features come additional costs. The better your unit, the more you can expect to pay. On the plus side, better brands mean better warranties and a longer lifespan.

Whether you have an existing HVAC system

If you have an existing HVAC system in place, you may pay lower installation costs than someone without an existing HVAC system. Most modern homes are set up for central air conditioner installation, but older homes might need some ductwork. If your home has old, worn or small ductwork, you may need to replace it to avoid higher energy bills or noisy operation.

Single-stage vs. multi-stage

Single-stage systems usually only operate at one speed. Single-stage units typically run at full power even when it isn’t necessary. Multi-stage units generally adjust to room temperature to ensure ideal comfort levels, saving you more on energy costs.

Costs to run a central air conditioner

To determine how much it costs to run your central air conditioner, take a look at some of the factors that go into that cost, including energy efficiency, maintenance costs and annual expenses.

Energy efficiency

Air conditioners with higher energy efficiency can save you more money on energy bills. Natural gas units generally cost more than electric units. However, both gas and oil prices can fluctuate from month to month.

Maintenance costs

The average cost for air conditioner service ranges from $50 to $140. Annual maintenance costs generally range from $70 to $100.

Costs to run per year 

The cost to run your central air conditioning unit per year varies, but you can easily calculate how that figure

First, you’ll need to know the total amperage and the size, as well as the standard voltage. Multiply the number of amps by the number of volts to get your total watts used. Then divide the number by 1,000 to get your kilowatt usage per hour. Then you’ll multiply the number of kilowatts used by how much you’re charged per kilowatt-hour (usually only a few cents) and you’ll know how much money you pay per hour. Multiply that number by how many hours you think you typically run the air conditioner per day and you can determine your central air conditioning energy costs for the year.

Additional costs to consider

In this section, we’ll take a look at additional costs to consider when it comes to purchasing a central air conditioner. Those additional costs can include new ductwork, a home insulation efficiency upgrade or new gas lines.

New ductwork

If your home isn’t already set up for a central air conditioning system, you may need to pay an additional $2,000 for new ductwork.

Home insulation efficiency

If your home isn’t properly insulated, you could end up spending between $1,400 to $2,300 on home insulation to ensure your air conditioning unit is working effectively. Insulation comes in a variety of different forms, so it’s difficult to pinpoint cost. You might consider these types of insulation:

  • Structured insulated panels
  • Foam boards
  • Concrete blocks
  • Rigid fibrous insulation
  • Loose-fill
  • Sprayed foam insulation
  • Blanket, batt and roll
  • Insulating concrete forms
  • Reflective system

New gas lines

Installing new gas lines may be required in order to install your new central air conditioner. The average cost is about $521, but it can range from about $120 to $1,350.
