A Handy HVAC Spring Cleaning Checklist

A Handy HVAC Spring Cleaning Checklist

HVAC systems are the most complicated part of any structure to maintain due to their many parts. However, when these parts are kept in top condition, all other components will function much more efficiently. There is an abundance of resources available for homeowners who want to perform their HVAC maintenance; however, there is little information available on how to go about this work.

Spring Cleaning Checklist

The following Spring Cleaning Checklist will make tasks much easier for you:

Remove Debris from Condenser Unit Drain

A Handy HVAC Spring Cleaning Checklist

If it has not been done already, remove the drain plug from the outside unit’s drain pan. A common error that results in reduced cooling performance is blocking or restricting airflow through the condenser unit. Removing the drain plug and clearing any debris out of the pan makes sure that there is nothing impeding airflow and allows for proper drainage.

Vacuum Interior Air Ducts

A Handy HVAC Spring Cleaning Checklist

The next step in HVAC Spring cleaning involves removing dirt from your air ducts with a vacuum cleaner. Although this may seem like a monotonous task, it is essential to maintain proper airflow and consequently cooling performance. An air duct cleaning kit can be obtained from one’s local hardware store if desired; however, using a good quality shop works just as well.

Note: If you have central A/C, it will automatically shut off while you vacuum your ducts unless you turn this function off in your thermostat.

Replace Damaged or Missing Duct Insulation

Replacing or repairing any missing or damaged insulation at your air ducts is a very important part of HVAC Spring cleaning. Without proper insulation, your heating and cooling system will have to work much harder, resulting in reduced energy efficiency as well as increased equipment wear and tear.

Clean Condenser Unit Fan Blades

The condenser unit fan blades should be cleaned at the same time as the rest of your exterior unit because it also gets covered with debris from around your property. Start by marking the power cord so that you don’t forget to plug it back in after cleaning the blades; then use an old paintbrush to remove all dirt. Next, use an air compressor to blow out any remaining debris.

Inspect Coil Fins

Before you can finish the exterior HVAC Spring cleaning checklist, it is important to check your coils for dirt or other obstructions. If there are any, carefully remove them with a soft-bristled brush. A coil fin comb may also come in handy if you have one on hand. Finish this step by using compressed air to thoroughly clean off the fins and ensure optimal airflow into your system.

Clean Evaporator Coils and Drain Pan

The evaporator coils are located within the home’s interior unit(s). This part should be cleaned at least once per year since all of the coolants passes through these coils before it reaches the furnace. Follow this HVAC Spring cleaning checklist to make sure that your evaporator coils are in top condition.

Replace Damaged or Worn Duct Work Segments

Once you have vacuumed out all of your air ducts, it is time to inspect them for any damage or wear. If there is significant wood rot on any segments of your flexible ductwork, replace them with new ones provided by a local hardware store or HVAC contractor.

Inspect and Adjust Unit Settings

Finally, check your unit’s settings and verify that they correspond with the current weather conditions for maximum cooling performance. Make sure that both the fan speed and cooling mode are set correctly; then turn off the power at the breaker before you finish the job.

The HVAC spring cleaning checklist is complete! All that’s left to do is sit back and enjoy maximum airflow and energy efficiency come summertime.
