How Much Does it Cost to Replace an Air Conditioning System?

As industry leaders providing quality air conditioning, heating, and indoor air quality services to the Greater Austin area since 1977, McCullough Heating & Air Conditioning knows how confusing it can be for homeowners when it comes to replacing their AC system. In order to make sure you fully understand the many factors that could affect the price to replace your home’s air conditioning system, we've whipped together this handy blog to guide you through your purchase. Take a peek!

Factors That Affect the Cost of Your Austin, TX AC Replacement

Type of AC system

While there are several different types of air conditioners you can buy, with a fairly broad cost range, the two main systems we recommend include:

  • Central air conditioners– A central AC system is made up of an indoor unit, an outdoor unit, and ductwork to help cool your entire home in the summer.
  • Mini-split (or ductless) air conditioners– Mini-split air conditioners typically work best in older homes where ductwork can’t be easily added or in those where homeowners wish to have a single area where air conditioning runs through. If you’re looking to cool your entire home, ductless AC systems may be more economical to operate but may be more expensive than central AC systems (excluding ductwork).

Size of the AC System

As with most products in the market, size/capacity inherently affects exactly how much you’ll be expected to cough up. When it comes to air conditioning units, size is expressed in tons. Generally speaking, larger air conditioning units tend to be more costly, as they have more capacity and can serve a larger area.

In order to determine which size unit is right for your home, your air conditioning contractor will need to perform a heat load analysis (or Manual J load calculation). These calculations take into account all aspects of your in-home environment, including the square footage of your home, window size and location, construction materials, wall construction and orientation, ceiling heights, flooring, appliances, insulation and more.

Energy Efficiency of the Air Conditioner

The higher the Seasonal Energy Efficient Rating (SEER), the more energy-efficient (and costly) the unit will be. The minimum efficiency air conditioner you can buy in Austin, Texas is a 14-SEER unit, but they can also go as high as 26-SEER. It’s similar to miles per gallon for your vehicle: the higher the SEER, the more efficient the unit.

HVAC Contractor You Choose

Surely, we know how important it is to do your research and make sure you’re getting the best deal you can find in Austin, but keep in mind: You often get what you pay for. While it is true that a smaller, one- to two-person contractor might be able to charge less for nearly every service they offer, a vast majority of air conditioning contractors in the area go out of business within five to eight years.

Before selecting a contractor, it is important to ask, “Will this contractor be able to come back right away when I encounter any problems?” Put yourself in a small contractor’s shoes: If you were slammed with installs during the peak season, how likely would you stop what you’re doing to service a system you installed five years ago?

Other Factors of AC Replacement to Consider

The cost of your air conditioning system replacement can be affected by other additional factors, including:

  • Duct repair/replacement– If you're experiencing uneven home cooling, higher-than-normal energy bills, or an uncontrollable amount of dust in your home, you might have some leaky ducts that may need to be repaired or replaced.
  • Zoning– Zoning allows you to control the temperature of individual areas within your home. Sometimes, an entire family can't agree upon a specific, comfortable temperature to sleep at night, and a zoning system could be the perfect solution to that problem.
  • Smart thermostats– Want access to your thermostat from your smartphone? Smart thermostats are a great way to control your home's temperature while you are away and save hundreds on energy bills annually.

How can I get a good deal on my AC system replacement?

For the best deal on your new air conditioning system, purchase in either late fall or springtime when contractors tend to be less busy and manufacturers are typically offering their best rebates. Take advantage of rebates and tax credits from Austin Energy and combine it with those manufacturer rebates for the biggest savings.

How do I know if the price I was quoted is fair?

Try and call around to schedule two to three appointments for quotes from different contractors in the Austin area on the estimated cost to replace your home air conditioning system. Since this is the third largest investment you’ll make (following your home and your vehicle), you want to be certain that the deal you're getting and the contractor you choose to work with is reputable and trustworthy.
