Changing or cleaning the filter

The first step is finding the filter. It may be behind the bottom panel of your indoor unit, or there may be two filters.

  • When removing a filter, make sure you insert the clean filter with the arrows on it pointing in the direction of the airflow.
  • When replacing your air handler filters, always use the same size and type that was originally supplied.
  • If you have a semi-permanent filter, you can take the filter out of the frame and vacuum it.
  • If you have disposable filters, they should be replaced every month with filters of the same size.

Setting the temperature while you’re away

When you’re going out of town for a few days, or when outdoor temperatures are moderate, don’t let your system run unnecessarily. When you return home, or when temperatures dictate, you can reset the system and it will immediately begin making your home comfortable again. If your heating system is not operational during the cold weather months, provisions must be taken to prevent the freeze-up of all water pipes and water receptacles.

Summer

Raise the thermostat to 85°F

Winter
