The installation labor for a 2.5 ton Rheem AC unit typically ranges from $2,000 to $4,000. Costs vary based on the following:
- Retrofit vs. New Install: Replacing an existing system is generally less expensive than installing a system in a home without central air.

- Electrical Work: Additional wiring or disconnect box installation may cost several hundred dollars.
- Permitting: Local code inspections, permits, and fees often add $150–$500.

What’s Included In A Typical AC Installation Package?
When you purchase a new Rheem air conditioner with professional installation, most HVAC contractors include:

- Installation and leveling of the new condenser unit
- Wiring and refrigerant line connection
- Connection to air handler/furnace and thermostat
- System startup and quality check
- Warranty activation

Long-Term Operating Costs: Energy Efficiency And SEER Ratings
The SEER or SEER2 rating (Seasonal Energy Efficiency Ratio) tells you how efficiently an air conditioner cools your home. Higher SEER2 means lower electricity usage. Here is how annual costs might differ for a typical American household (at $0.14 per kWh, 1,500 hours of cooling per year):
| Rheem Model | SEER2 Rating | Estimated Annual Electricity Cost |
|---|---|---|
| Rheem Classic | 15.2 | $825 |
| Rheem Classic Plus | 16.5 | $765 |
| Rheem Prestige | 18.0 | $700 |
Investing in a higher-efficiency model can save $100–$300 annually, depending on your climate and usage.

Should You Replace Your Existing System Or Upgrade?
If your central AC is more than 10–15 years old, upgrading to a modern Rheem model can provide:
- Lower energy bills due to improved efficiency standards
- Enhanced comfort with quieter operation and better humidity control
- Fewer repairs and peace of mind from warranties
Older systems with R-22 refrigerant should be replaced, since R-22 is now phased out and costly to recharge. New Rheem units use environmentally-friendly refrigerants, complying with current law and supporting sustainability.
