HVAC equipment has a possibility to fail if they are not maintained properly, just like any mechanical equipment.

This is the reason why there is HVAC preventive maintenance checklist that you can follow so that you can avoid problems before they even occur.

Following this checklist, you can create your own schedule and you can also document the procedure and the things that you have accomplished.

It is important to inspect your HVAC equipment at least twice a year. It is also important to check on your chillers and boilers, since they are seasonal, and they are not used all year round.

It is even highly recommended to contact a mechanical contractor to check on your chiller and boiler, to make sure that everything is working perfectly.

You also need to inspect your cooling tower and its components including the fill valve, the fill, the sump, the spray nozzles, the support structure, the drive coupling, the gearbox, the motor bearing and the fan blades also, inspect the wiring and the motor starter for proper operation and wear.

Another thing that is a part of the HVAC preventive maintenance checklist is lubricating the bearings of your house pumps yearly. Check the couplings and see if there are any leaks that you need to fix.

Try to listen for any unusual pumping noises so that you can determine the cause of it.

As for your air conditioner, there are also things that you need to do with it that are included in the HVAC preventive maintenance checklist.

Check for molds in your system and clean them immediately. You can also apply a mold inhibitor to kill the mold and prevent it from coming back. This should be done quarterly.

Check your filters, if you see them all worn out and if they are dusty and dirty, then it is time to replace them. This could help you save on energy if your filter can be used to its full potential.

If you have a permanent filter, then you need to clean it every three months.

You also need to remove anything that is in the way of your air vents and clean the clutter.

The proper ventilation of air can help you save on your electricity bill. The efficiency is reduced if the airflow is blocked, this is also the reason why it is best to clean your condensing unit at least once every three months.

It is also highly recommended to clear everything that is blocking its way, such as leaves, branches, weed and more. You can use a broom or a soft brush to clean your condensing unit and you can spray it down using a water hose, but you need to turn the breaker off first.

Here are the other things that are on the checklist:

  • Check your refrigerator level
  • Clean the condenser coil and the evaporator
  • Clean the condensate drain and make sure that it is not blocked
  • Clean and adjust the blower components
  • Check the function of your thermostat and make sure that it is working properly
  • Look for duct leaks and measure the airflow in your home
  • Check all of your electrical connections
  • Lubricate all of the moving parts
  • Verify the safe operation of your system
  • Clean, rinse and repeat the process as HVAC maintenance should be done at least twice a year

These HVAC maintenance checklists can prevent the breakdown of your HVAC system and it can also prevent problems from occurring in the future.

Of course, there are instances wherein you will need a professional to do the cleaning and the maintenance for you, so it is best to call a professional to do the checkup.

Remember to do this twice a year so that unplanned expenses won’t occur and your place can be comfortable to live in.
