Home Safety

The safety of you and your loved ones is important during any season. Follow these steps for keeping your home safer during fall or any season:

  • Check the batteries in smoke detectors. If you have combustion appliances, a furnace, fireplace or wood stove, you should also make sure you have carbon monoxide (CO) detectors installed and in working order.
  • Attached garages should be sealed off from the living spaces. Install weatherstripping around the access door, and caulk any holes you see in walls and the ceiling. Attached garages are common sources for CO infiltration.
  • Seal cracks in walkways and the driveway.

Home Comfort and Efficiency

Take specific measures to make your home more comfortable and efficient for the forthcoming cooler weather.

  • Inspect weatherstripping around entry doors, and install as needed to seal air leakage.
  • Caulk cracks and gaps around windows.
  • Check exterior pipes, electrical wiring and cables for gaps and cracks that need caulking.
  • Boost attic insulation.

Fall HVAC Checklist

Schedule fall preventive maintenance with your Dallas HVAC contractor to ensure safe and efficient performance of your furnace or heat pump. These are just a few of the checks he will perform:


  • Check for gas leaks
  • Check the ignition system
  • Check and clean burners
  • Check heat exchanger for cracks
  • Check the flue or chimney for proper draft

Heat pump

  • Check reversing valve
  • Check defrost board
  • Check heat sequencers
  • Check for airflow restrictions (supply outlets, return grilles and outside cabinet)
  • Clean or change the filter (heat pump and furnace)

If you use a whole-house dehumidifier during the cooling months and/or a whole-house humidifier during the heating months, your Dallas HVAC pro can help you clean, inspect and prepare these systems for summer’s end and the arrival of fall.
