Final answer:
In heavy snowfall areas, it is good practice to mount the heat pump's outdoor unit on an elevated platform to prevent snow from blocking the coil.
Step-by-step explanation:
In heavy snowfall areas, it is good practice to mount the heat pump's outdoor unit on an elevated platform to prevent snow from blocking the coil. This is because snow accumulation can hinder the airflow and reduce the efficiency of the heat pump.
The elevated platform allows the heat pump to be raised off the ground, keeping the coils clear of snow and allowing for proper air circulation. This helps maintain the heat pump's performance and prevents potential damage.
Other options like wood, concrete, or plastic platforms may not be ideal in heavy snowfall areas as they may not withstand the weight of the heat pump or provide sufficient elevation to prevent snow accumulation.
