HVAC System Cleaning Tips

Posted on

HVAC units work to heat and cool the home in addition to filtering the air within it. Over a 12 month period, the majority of these systems will accumulate a large amount of debris and dirty. Not only does this work to ruin the quality of air within the home, but it also work to reduce the overall efficiency of the unit itself. By taking part in regular cleanings, you will be doing your part to ensure better air quality and unit functionality. In this article, we will outline the steps necessary to keep your unit running smoothly.

Air Conditioning

Step 1 – Outside the home you’ll find a condenser unit. Unplug the unit or flip the breaker to power it off.

Step 2 – Take a vacuum to the unit in order to remove the debris and dust along the fins. If there are weeds or grass nearby, employ the use of a weed whacker to clear the area as a way to prevent any clogs.

Step 3 – With a screwdriver, remove any screws along the top of the condenser and lift the top open. Be cautious when pulling up the cover so as not to cause any damage to the fan. Next, use a hose to spray the condenser, thereby cleaning out any dirt or debris.

Step 4 – Unscrew the cap on the condenser drain line. Pour yourself a cup of bleach and pour it into the drain line in order to eliminate any bacteria or algae. Allow the bleach to sit for about an hour, and attach a we/dry vacuum with the paper filter removed to the drain line. Turn the vacuum on for five second periods to remove the dead algae and bleach without doing harm to the line itself.

Step 5 – Take off the lid which covers the inside unit by pressing on the access button. Take out the filter, inspecting it for any debris and dirt. You may need to replace the filter if it is too dirty.


Step 1 – Remove the access panel to open up the indoor unit.

Step 2 – Flip the circuit breaker to the off position in order to turn off power to the unit.

Step 3 – Take a vacuum to the blower compartment and burners on the unit. Remove as much dust as you possibly can.

Step 4 – Remove the retaining nuts in order to gain access to the blower fan control panel. Remove the panel and allow the control to hang. Unscrew the retaining bolts in order to remove the blower fan and clean the fins using a soft brush.

If you’ve completed the steps outlined above and do not notice any improvement in your air quality or unit performance, it may be time to look into the possibility of a new unit. Place a call into your local HVAC specialist and schedule an appointment in order to assess whether repair or replacement is needed. Your HVAC technician will be able to provide you with information to help make a decision regarding the future of your current HVAC unit.
