Heat Pump Energy Savers

For heat pumps with outdoor coils, the location of the outdoor unit may affect its efficiency.

Outdoor units should be protected from high winds, which can cause defrosting problems. You can strategically place a bush or a fence upwind of the coils to block the unit from high winds.

Proper operation of your heat pump will also save energy. Do not set back the heat pump's thermostat if it causes the backup heating to come on. Backup heating systems are usually more expensive to operate. Continuous indoor fan operation can degrade heat pump performance unless a high-efficiency, variable-speed fan motor is used. Operate the system on the "auto" fan setting on the thermostat.

And like all heating and cooling systems, proper maintenance is key to efficient operation. Clean or change filters once a month or as needed, and maintain the system according to manufacturer's instructions. Dirty filters, coils, and fans reduce airflow through the system. Reduced airflow decreases system performance and can damage your system's compressor. Clean and lubricate the fan motor annually to ensure the required airflow is provided for proper operation. The fan speed should be checked at the same time. Incorrect pulley settings, loose fan belts, or incorrect motor speeds can all contribute to poor performance.
