- Keep your thermostat set to a reasonable temperature, unless there are residents with special needs.
- Summer recommended temperature settings:
- during wake hours is 78º F or higher
- during sleep hours is 78º F to 82º F
- Winter recommended temperature settings:
- during wake hours is 70º F or less
- during sleep hours is 70º F to 62º F

- An AC unit will work more efficiently in the shade.
- Direct sunlight adds heat to the outdoor unit, causing the entire AC system to work harder to cool the outside coils.
- If your AC unit was installed in an area where it is in the sun most of the day, try planting shrubs or trees around it. The cooler the unit, the better it will cool your home. Leave sufficient room for ventilation by making sure not to plant too close to the unit. Keep weeds and other structures away from the cooling unit.
- Check unit occasionally to ensure flowers, bushes, weeds and other structures are not restricting airflow around the unit, which reduces cooling efficiency.
- Planting trees in ideal locations away from power lines will reduce heat from direct sunlight on your home.
- In the summer, shade trees lower the temperature of your home’s siding, reducing the amount of energy needed for cooling.
- In the winter, when leaves are off the trees, sunlight can warm the siding, reducing your heating costs.
The SEER rating is a measure of the efficiency of an air conditioning system determined by measuring the cooling output for a specific energy input. The higher the SEER number, the less energy is needed for cooling and the more efficient the system.
In addition to the SEER rating, it is also important to match the coil and blower to ensure you achieve the optimal SEER rating. Your HVAC contractor should be able to provide you with guidance and options.
