Spring/Warm Weather Preparation

Spring is finally here! There are many things you can do now to avoid problems and have a trouble-free spring. Here are a few suggestions.

  • Schedule yearly preventative maintenance on your heating, cooling, and hot water equipment.
  • Replace all air filters.
  • Keep your home comfy upon your arrival by investing in a wireless thermostat. Monitor your home while your away.
  • Clean your registers, vents, and baseboards to remove dust buildup and pet dander before you turn on your air conditioner.
  • Keep access to outside equipment easy for maintenance. Avoid planting in these areas.
  • Remove any debris and vegetation around the outside of your air conditioning condenser. Restricted air flow will only make your air conditioning work harder than it must reducing the efficiency.
  • Replace batteries in smoke detectors/CO2 detectors.
  • Set ceiling fans to run clockwise to direct cool air downward and to circulate it throughout the room.
  • If your condenser is in direct sunlight and heat, it will get hot. The hotter it gets the harder it works. Shade will help to protect it from the worst of the heat. In doing so you must remember to not block or restrict the airflow.
