Tech explains AC installation cost to homeowner outdoors near air conditioner on sunny day.

No matter how well you maintain your air conditioner, you’ll have to replace it sooner or later. At that point, it comes down to a simple question: How much will a new AC installation cost? Take it from the pros at Gross Heating & Air Conditioning—the answer depends on a few different factors. Below, we’ll share a few of them. Read them over, then call us to set up an estimate for a new system.

Home Air Conditioner Installation Variables

System Size

Believe it or not, air conditioners come in different sizes. In fact, measuring your house is one of the first steps our team takes when we start the installation process. It lets us know how big your home is—and what size air conditioner you’ll need to best suit your needs. A system that’s too small will run constantly in order to meet your desired temperature. And one that’s too big won’t cycle properly. Both can lead to energy inefficiency, which can inflate your utility bills.

Type of Air Conditioner

Not only are there different AC sizes—there are also different types of units. Certain cooling systems work exactly as you’d think: When you adjust your thermostat, the AC kicks on until that temperature is met before shutting off. However, other kinds operate at variable speeds, meaning they cycle through different stages depending on your home temperature to maintain optimal energy efficiency. These types cost more but make up for it in terms of energy savings.

In addition to these, you could also consider alternative cooling solutions, such as ductless split systems or heat pumps.

SEER Rating

SEER, or Seasonal Energy Efficiency Ratio, indicates just how well any given AC uses energy. All systems have a SEER of at least 13. The higher the number, the more efficient the system—and the higher the AC installation cost. However, as with the point above, the amount you save on energy can help make up for the initial price tag over time.


If you already have a central air conditioner and you’re installing the same, you must already have ductwork. But if your home doesn’t have ductwork, the cost of your AC unit installation will be much higher. In that case, we might recommend a high velocity or ductless system depending on your home. These individual units can be installed directly into rooms for customized temperatures across the house. It may be a cheaper option for you than retrofitting ventilation.

The Team You Choose for Installation

Though certain air conditioners are more energy-efficient than others, one of the biggest factors is who you choose to install your system. Your best bet? Gross Heating.
