Are heat pumps distinctively regulated by a specific code from central air-conditioning systems?

Heat pumps are generally not subject to a specific code that is distinct from those that apply to central air-conditioning systems. Instead, both systems typically fall under the same regulations and codes that govern HVAC equipment and installations in general. These regulations often cover safety, efficiency, and performance standards applicable to heating and cooling systems.

The confusion may arise because heat pumps can operate in heating mode as well as cooling mode, while traditional air-conditioning systems do not provide heating. However, the codes related to installation, maintenance, and operation focus more on the overall system performance and safety rather than separating these two types of systems into completely distinct regulatory categories. Therefore, the correct answer reflects the shared regulatory framework applicable to both heat pumps and central air-conditioning systems.
