AC Installation in
Chicago, IL
Four Seasons has installed AC systems in Chicago homes since 1971, covering every major system type your home might need. Chicago summers push heat indexes past 100°F, and a system sized wrong for your home raises your ComEd bill every single month it runs.
Most Chicago homeowners who call us mention the same experience: another company gave them a low quote, then added permit fees and disposal costs on the final invoice. We give you a full written quote before any work starts. The invoice you pay matches that number. That is how we have earned more than 51,000 verified reviews since we opened.

| Will someone actually show up on time? | We confirm a specific arrival window and call when your tech is on the way. Our 600+ trucks mean we have someone available. | Many companies give 4-to-8-hour windows and reschedule when jobs run long. |
| Who is coming into my home? | Our technicians are direct Four Seasons employees. Everyone passes a background check and holds EPA Section 608 certification. | Some contractors dispatch subcontractors with no standardized background check requirement. |
| Will this company still answer if something goes wrong? | We have served Chicago since 1971. We answer warranty calls for every system we install. | Newer or out-of-area companies may not be reachable when you need warranty service six months later. |

How Much Does It Cost to Install a New AC System?
The cost to install a new central air conditioning unit depends on what you want in terms of efficiency, compressor type, and upgrades. Costs will also depend on your home's specific circumstances, such as whether duct modifications are needed, whether electrical work is required, whether the unit is located on the roof, in the attic, or in the yard, and whether the indoor evaporator coil or refrigerant line needs to be replaced.
That said, we still want to provide a ballpark estimate so you feel more equipped to take the next step toward replacing your AC.
| Typical Range | Average Cost |
|---|---|
| $4,500 – $14,880 | $5,750 |
Factors to Be Aware of That Affect Cost
Every home’s cooling system is a little different, and so are the conditions that determine the total installation cost. At Four Seasons, we believe in clear pricing. This helps you see why costs can change from one project to another.
Below are the most common factors that influence what you’ll pay for a new central air conditioning system:
SEER Rating
More efficient systems cost more upfront. However, they lower your energy use and utility bills over time.
Compressor
You can choose from single-stage (most affordable), two-stage, or variable-speed compressors. Variable-speed models are quieter and provide more comfort, but they cost more.
System Size (Tonnage)
Larger homes require higher-capacity units (measured in tons), which impacts equipment and installation cost.
Indoor Coil
If your old evaporator coil or line set needs to be replaced, it will add to the total cost. This is necessary to match the new system’s refrigerant type or efficiency level.
Location
Units placed on rooftops, in attics, or small side yards require more setup time. They also need additional safety measures compared to ground-level installations.
Home Modifications
Ducts may need adjustments. New breakers or dedicated circuits may be required.
Add-On Comfort Features
Upgrades like smart thermostats, zoning controls, and purifiers.
