Seasonal Tips… SUMMER

Summer Energy Saving Tips:

If You Lose Power. . .

If your air conditioner or heat pump is running and you experience a power outage for any reason, (lightning strikes, storms, power line damage, etc.) a shut-off sensor in the unit can be activated.

Lightning striking overheadThis sensor is called the "time-delay" sensor. It protects the unit from any further damage due to successive power surges by preventing the unit from re-starting immediately. The time before the unit can come back on varies between 10 and 20 minutes.

If this happens, turn the system to "Off" at the thermostat and wait 20 minutes to allow the sensor to re-set before attempting to turn the unit back on. If it does not restart, then call for service.

  • Blow grass clippings away from the condensing unit to keep clippings from blocking the coil.
