Checklist For HVAC Maintenance

Check out this simple and practical list of various preventive HVAC maintenance you can do to make sure your HVAC system is always in great shape.

Homeowners are advised to consult an HVAC contractor in checking their system and in doing routine HVAC maintenance tasks. Most likely, they’ll check and clean your unit’s wiring and various mechanisms, which an ordinary homeowner is not familiar and skilled in doing. You can extend your system’s lifespan and boost its efficiency by following this easy HVAC maintenance plan.

These are the tasks you should do right away, monthly or every season or at least once every year to achieve and maintain a healthy and efficient HVAC system …


  • Purchase a highly-efficient pleated air filter. That is if you haven’t bought one yet. Modern pleated filters are highly efficient and release an electrostatic charge that operates similarly to a magnet by grabbing even minute particles – even the ones that harbor bacteria.
  • Make sure your air conditioner and furnace are free of any dirt buildup, leaves, grass or pollen. Also, when mowing your lawn, make sure it does not discharge its grass clippings in the direction of your HVAC unit.
  • Make sure your outdoor cooling and heating units have free spaces of at least 2 feet all around it. Any form of blockage can interfere with the way your system works and ultimately affect its efficiency.

Monthly or seasonal:

  • Check your refrigerant line every month. If they are missing or already damaged, don’t hesitate in replacing it.
  • Change your air filters each month or every 90 days at the very least, but don’t forget to check it on a monthly basis. For homeowners who have pets at home, the need to change it monthly is non-negotiable.
  • During summer, shut off the water to you furnace humidifier.
  • During fall (or when you’ll likely turn on your heating system once more), change the wick filter of your humidifier and turn on the water. Also, make sure you set your humidistat’s relative humidity anywhere in between 35% up to 40%.Don’t close over 20% of the registers in your home so you don’t unnecessarily strain your HVAC system and force it to work harder.


  • Change the battery of your carbon monoxide detector. You can never tell when carbon monoxide is leaking. And because it can kill you without you knowing, having a reliable carbon monoxide detector is a must.
  • Make sure your AC unit outside is on a firm as well as level ground.
  • Keep a clear AC condensate drain by using bleach and water mixture. It will prevent mold and algae buildup that can result to annoying clogs.

Some of this HVAC maintenance you can safely do on your own, some you can’t. Contact your trusted HVAC contractor in the maintenance and repair of your system, so you not only extend its lifespan but boost its efficiency as well. Maximize what’s your money’s worth and ensure your family’s safety all year round without sacrificing home comfort and convenience.
