Most central air conditioner replacements in Morris, IL cost $5,000 to $9,500 installed, and replacing the furnace at the same time typically runs $9,000 to $16,000. Where your price lands depends on the efficiency you choose, the size of your home and the condition of your ductwork. A standard 14.3 SEER2 single-stage air conditioner sits at the low end, a two-stage model in the middle and a variable-speed model at the top.
In this blog, we’ll dive into everything you need to know about installing an AC unit, including cost determinants, tips for hiring the right professional, and what to expect during the installation process.
Factors That Determine the Average Cost of AC Installation in Morris, IL
Type of AC System
Central AC installation costs are typically higher than mini split AC installation due to the ductwork required. Central systems are great for whole-home cooling, while ductless mini splits are perfect for zoned cooling solutions.
Size of the Unit
The size of the AC unit is crucial. Larger homes need higher-capacity units, which cost more. A professional will perform a load calculation to determine the correct size for your home.
Existing Ductwork
If your home already has ductwork in good condition, you’ll save money on installation. Leaky or undersized ducts usually add $500 to $2,000 for sealing or repairs, and a home without ductwork is priced at the free in-home estimate.
Labor & Installation Complexity
An indoor coil in a tight attic or crawlspace, a long refrigerant line run or an electrical upgrade for the new outdoor unit all add labor to an AC installation.
Permits and Inspections
Depending on local regulations, a new air conditioner may need a permit and an inspection. Ask us about the permit when we quote your new AC.
SEER2 Rating
SEER2 measures how efficiently an air conditioner cools over a season. The higher the SEER2 rating, the less electricity the air conditioner uses and the more it costs upfront. Our good, better and best options run from a 14.3 SEER2 single-stage air conditioner to a 17+ SEER2 variable-speed model.

Questions You Should Ask an AC Installation Professional
When hiring an AC installation service in Morris, IL, here are some essential questions to ask:
- Are you licensed and certified? Always verify that your installer has the necessary credentials to perform the job safely and legally.
- Can you provide a detailed quote? Ask for a breakdown of all costs, including equipment, labor, and potential extras like permits or inspections.
- Do you offer warranties? Check if there’s a warranty for the unit and the installation service. A reliable contractor should stand by their work.
- What is the timeline for installation? Get a clear idea of how long the process will take so you can plan accordingly.
- Do you offer maintenance services? Ongoing maintenance is key to extending the life of your AC unit, so it’s helpful to choose a provider that offers these services. Reliable contractors such as EZ Air offer convenient and affordable maintenance plans so you can stay comfortable throughout the year!
What to Expect from an AC Installation Service
When installing an AC unit, a reliable service provider will follow a structured process to ensure your system operates efficiently and meets your home’s cooling needs. Here’s a more detailed look at each step in the process:
1. Initial Consultation and Load Calculation
Before installation begins, the professional will visit your home for a consultation. During this phase:
- Load Calculation: Using specialized tools, the technician will calculate the cooling load for your home, considering factors like square footage, ceiling height, insulation, and the number of windows. This ensures you get a unit that is neither too small (leading to inefficiency) nor too large (resulting in short cycling and higher energy costs).
- Recommendation of Unit Type: Based on your home’s layout and needs, the installer will recommend the right AC system, be it a central AC unit, a ductless mini split, or another option.
2. Removing Old Equipment
If you’re replacing an old AC unit, this step involves:
- Safe Removal: The installer will safely disconnect and remove the old equipment, including refrigerant lines and electrical connections, following EPA guidelines to prevent environmental damage.
- Proper Disposal: Any refrigerants or other hazardous materials are disposed of in compliance with local laws.
3. Installing New Equipment
This is the core part of the process and involves multiple steps depending on the system being installed:
- Outdoor Condenser Installation: For central AC systems, the outdoor unit (condenser) is installed on a level surface. The location is chosen to maximize efficiency while minimizing noise and exposure to the elements.
- Indoor Unit Setup: For central systems, the evaporator coil is installed near the furnace or air handler. For ductless systems, wall-mounted indoor units are strategically placed to ensure optimal cooling in designated zones.
- Ductwork Installation or Modification: If installing a central system, the installer will either use existing ductwork or install new ducts if none are present. This may involve cutting into walls, ceilings, or floors.
5. System Testing and Calibration
This is the final phase and ensures your new AC system is ready to perform at its best:
- System Startup: The technician will power up the system and monitor its performance.
- Airflow Testing: Airflow from the vents or indoor units is measured to ensure consistent cooling throughout the home. Adjustments may be made to optimize performance.
- Thermostat Calibration: The thermostat is calibrated to ensure accurate temperature readings and effective communication with the system. If you’ve opted for a smart thermostat, the technician can also help you set it up and provide guidance on its features.
- Owner Walkthrough: Finally, the installer will provide a walkthrough of the system, explaining basic operation, maintenance tips, and warranty information. Experienced AC installation companies, such as EZ Air, also offer maintenance plans to ensure your system continues operating optimally in the long run.
Frequently Asked Questions
How long does AC installation take?
Most air conditioner replacements are finished in one day. Replacing the furnace at the same time, or adding ductwork or an electrical upgrade, can add a day.
Are there energy rebates for installing a high-efficiency AC unit?
The rebates in Morris are on heat pumps: ComEd gives instant discounts of up to $2,000 in 2026 on qualifying heat pumps installed by a ComEd heat pump-trained contractor. Standard central air conditioners do not get a ComEd rebate this year, so it is worth pricing a heat pump installation in Morris next to a new AC.
What maintenance does a new AC unit require?
Regular filter changes, annual professional inspections, and cleaning are essential to keep your system running efficiently. Contact EZ Air to learn more about maintenance options after installation.
