Your HVAC system serves as a heart of your home. We love it when it is properly functioning and hate it when it is not operational. Although a HVAC broken system isn’t a big deal in mild weather but it must be operational at all times during winter and summer to keep your home warm and cool respectively. Sudden failure of your heating and cooling system could be due to improper maintenance like dirty HVAC equipment. Therefore, your heating, ventilation and air-conditioning system needs annual inspections to run smoothly and efficiently. Regardless of HVAC breakdown inconvenience, it can be very expensive to get a new system or repair it. So, the question arises how to inspect your HVAC system? The good news is that you can conduct regular HVAC system inspection yourself to keep it in good working condition and can consider contacting a certified professional to save your HVAC investment. Here I will briefly explain some steps to conduct your own HVAC inspection.

  • Start with the thermostat: First of all, check whether your thermostat is properly working or not. Also have a check on heating and cooling mechanisms, open the thermostat and use the Q-tip to clean the device.
  • Shut off the power: Make sure to turn off the power unit before starting the inspection. It is really very important because you will soon be checking or cleaning parts of the unit and there is high risk of electric shock so switch off the source of power first.
  • Remove debris from the external HVAC unit: You will need a screwdriver and a wrench to separate the fan cage. Later, remove debris or dirt from inner parts with the help of wet or dry vacuum.
  • Clean and repair the fins: You can use a sprayer hose to wash away debris from the interior of the unit. Using a pressure washer can be harmful for being a little powerful. You can also get fin-cleaning spray from your local hardware store if the fins are too dirty. The fins are designed straight to keep airflow efficient so whenever you want to straighten the fins then do it with help of a butter knife or other fin-straightening instrument. Afterwards, reattach the fan cage and that’s it.
  • Clear the area around the unit: There will be at least two feet of distance between your external unit and other equipment. You can place a piece of plywood or plastic to keep the top of the unit safe from falling rubble but don’t cover it as vermin can hide there during off months.
  • Level the unit: Your HVAC system can move overtime and an unlevelled condenser result in compressor failure before time. So, if your unit is not level then adjust it.
  • Clean the evaporator coil: Now it’s time to move the internal unit. Expose the evaporator coil door to clear the dust and spray coil cleaner. Use hot water, soap and a little bleach to clean it further.
  • Check the evaporator drain: If your evaporator drain is clogged then it can cause flooding types issues so remove the debris in the drain which hinder the flow of running water with the help of wet or dry vacuum.
  • Replace the filter regularly: Your HVAC unit usually creates big issues if it is not properly replaced on time as it traps debris from the system that causes malfunctioning.  Filter must be changed after six months on every cost or at least after one to three months for ideal results.

Finally, check the duct work for any leaks and inspect the air vents for debris or rodent presence. To keep yourself away from headache and inconvenience brought by a malfunctioning HVAC system, arrange a regular inspection. I hope this stuff will help you to understand how to inspect your HVAC system and maintain it to prolong its lifetime.
