How is heat pump installation different from a standard AC replacement?
The work looks similar. The crew removes the old equipment, sets a new outdoor unit and indoor air handler, connects the lines, wiring and drain, and tests the system. Some differences are worth knowing.
- Controls. A heat pump needs a compatible thermostat that manages heating, cooling and the backup heat strips.
- Backup heat. Most heat pump air handlers include electric heat strips for cold nights, and these need the right electrical supply.
- Defrost. The outdoor unit can build frost on a cold, damp morning and runs a defrost cycle. Drainage around the pad matters.
- Airflow. Heating mode often needs good airflow, so the ducts should be checked.
If your goal is to cool only, you may prefer a standard system, and our page on AC installation covers that. A technician can explain which fits your home.
