What Is Included In AC Unit And Air Handler Installation?

Professional installation should be comprehensive, covering removal of existing units, refrigerant evacuation, new line set installation, electrical upgrades, mounting, leak testing, and full system commissioning. Most reputable contractors provide a warranty on labor, in addition to manufacturer coverage on components.

• Old system removal & disposal
• Electrical and refrigerant line connections
• Thermostat installation or wiring updates
• System refrigerant charge and pressure testing
• Performance calibration and permit handling

Skipping steps or improper matching can void warranties and significantly reduce system efficiency.

Matching The Right AC Unit And Air Handler

Ensuring compatibility between condenser and air handler is key for efficiency, reliability, and warranty purposes. Mismatching can cause system failures, energy waste, or comfort issues due to incorrect airflow or pressure.

Manufacturers provide AHRI certified matched system pairings. Always follow these recommendations, especially to qualify for utility rebates or incentives.

Energy Efficiency And AC/Air Handler Costs

High-efficiency AC systems (16 SEER and above) cost more initially, but lower monthly electric bills and may qualify for federal and utility rebates. Air handlers with variable speed motors further reduce energy usage and improve humidity removal, contributing to year-round comfort.

With current energy codes and EPA standards, many installers recommend at least 15 SEER for southern states and 14 SEER minimum elsewhere in the US.

Is It Cheaper To Replace Both AC Unit And Air Handler Together?

Coordinated replacement of both units often delivers better long-term value. Mismatched components can create performance issues and typically void manufacturer warranties. Most HVAC professionals advise full system upgrades every 15-20 years or when major efficiency standards change.

Bundling installation can also yield labor discounts and ensure up-to-date compatibility with smart thermostats or zoning equipment.

Brands And Warranty Considerations

Major brands in the US market include Trane, Carrier, Lennox, Goodman, Rheem, and York. Each offers a range from entry-level to premium models, with extended warranties up to 10-12 years on compressors and parts when installed by certified contractors.

Choose brands with reliable local support and proven longevity, even if initial cost is higher. Strong warranty coverage and readily available parts save money over the system’s lifetime.
