Should I replace the AC and furnace at the same time?

If both are near end of life, replacing together gives you one matched, right-sized system, one labor mobilization, and aligned warranties — often cheaper than two separate jobs. If only one has failed and the other is newer, a good installer confirms the AHRI match instead of upselling the pair.

Does replacing both as a system improve efficiency?

Yes, when it's done as a matched set. The rated SEER2 only holds for an AHRI-certified combination of condenser, coil, and air handler, and a whole-system changeout is the moment to right-size with an ACCA Manual J load calculation rather than copying the old equipment.

Does replacing both the AC and furnace in Greensboro require additional inspections or permits?

Replacing matched systems may trigger additional permit and inspection requirements under the 2021 code. Homeowners should ask whether the contractor will pull required permits and schedule any municipal inspections. Confirm who will handle permit fees and inspection coordination.

When should a homeowner expect final commissioning tests after a condenser or combo replacement?

Final commissioning tests should occur immediately after installation and before job closeout. Tests include airflow verification, refrigerant charge, thermostat calibration, and system run-time observation. Request a written commissioning checklist that the contractor will sign and deliver.
