ENERGY SAVING TIPS

1. CLEAN OR REPLACE INDOOR RETURN AIR FILTER
   A clean return air filter will allow for proper airflow and will ensure that your system is running at its optimum performance and efficiency. Check your air filter every 30 days during cooling and heating seasons, and clean or replace it if its dirty.

2. INSTALL A PROGRAMMABLE, WI-FI, SMART THERMOSTAT
   A programmable Wi-Fi smart thermostat will allow you to monitor and control your homes cooling and heating temperature settings from a smart phone, tablet, or computer whenever you are away. They are designed to provide comfort and energy savings by using algorithms and operating history to adjust the operating settings throughout the day.

3. ADJUST THERMOSTAT SETTINGS
   Programming an occupied & unoccupied schedule throughout the week will not only save energy, it will also reduce the wear and prolong the lifespan of your equipment by preventing the system from operating when it is not necessary.

4. ROOMS EXPOSED TO DIRECT SUNLIGHT
   In the cooling season it is recommended to block the radiant heat effect from the sun by closing all window coverings during the daytime.
   In the heating season it is recommended to open all window covers to allow for the radiant heat from the sun to help warm the spaces being conditioned.

5. ROUTINE MAINTENANCE & SERVICE
   Keeping the area around the outdoor unit clear from any debris or leaves will allow for your system to run at its optimum performance and efficiency in both cooling and heating seasons.
   In heating mode, be sure to clear the underside of the unit of any snow or ice that may accumulate fol-lowing defrost cycles. It is critical to the proper operation of the heat pump that the outdoor unit is never buried, even partially, by ice or snow.
   A heat pump shelter protecting the outdoor unit from excessive snow accumulation is sometimes required in certain situations where the weather is more frequent and regular. Consult your GREE Canada-certified installer for more information on shelters that can be installed.
   Scheduling a pre-season routine maintenance to be performed by a licensed HVAC contractor can improve the systems
