So, you’ve decided it’s time to upgrade your air conditioner—great choice! A new AC system can bring improved comfort, energy efficiency, and peace of mind for years to come. But if you’ve never had one installed before, you might be wondering what the process looks like.
Here’s a step-by-step breakdown of what to expect during a new AC installation, from the initial consultation to the final system check.
1. Pre-Installation Consultation
Before installation day, a licensed HVAC technician will visit your home for an in-home evaluation. During this visit, they will:
-
Assess your home’s layout and size
-
Check existing ductwork and insulation
-
Calculate the correct AC size (using load calculations)
-
Discuss your comfort preferences and energy efficiency goals
-
Provide a detailed estimate for equipment and labor
✅ Tip: This is a great time to ask questions about SEER ratings, brand options, warranties, and financing plans.
2. Preparing for Installation Day
On the day of installation, the crew will arrive with your new equipment and necessary tools. Here’s how you can help things go smoothly:
-
Clear the area around your indoor and outdoor units
-
Ensure pets and children are kept safely away from the work zone
-
Move any fragile or valuable items near the workspace
Most installations take 4 to 8 hours, depending on the complexity of the job.
3. Removing the Old Unit
The team will first disconnect and remove your old AC system. This may include:
-
Safely draining refrigerant
-
Disconnecting electrical wiring
-
Removing the old air handler or furnace (if applicable)
-
Hauling away old equipment for proper disposal
4. Installing the New System
Next, the crew will install your new air conditioner. This includes:
-
Setting the outdoor condenser unit on a level pad
-
Installing or replacing the indoor air handler or evaporator coil
-
Connecting refrigerant lines, drain lines, and electrical components
-
Sealing and securing all duct connections
-
Installing a new thermostat (if included)
✅ Note: If you’re upgrading from an older system, there may be some minor modifications to your ductwork, wiring, or line sets.
5. System Testing and Calibration
Once everything is installed, the technician will:
-
Pressurize and vacuum the refrigerant lines
-
Add refrigerant (if needed)
-
Power on the system and run a full diagnostic
-
Calibrate the thermostat and ensure proper airflow
-
Test temperature output, pressure levels, and overall performance
They’ll also check for any leaks or strange noises and make sure your system is operating within manufacturer specs.
6. Final Walkthrough and Instructions
Before they leave, the technician will:
-
Show you how to use your new thermostat
-
Explain maintenance tips (like filter changes)
-
Review warranty coverage and registration
-
Answer any final questions you have about the system
You’ll also receive documentation about your new AC, including manuals, service recommendations, and warranty info.
7. Post-Installation Support
A reputable HVAC company will offer continued support after installation, including:
-
Maintenance plans
-
Warranty servicing
-
Seasonal tune-ups
-
Emergency repair services
✅ Tip: Schedule your first maintenance appointment 6–12 months after installation to keep your system running like new.
