How To Clean Hvac Coils Like a Pro

In cases where maintenance checks aren’t being made, it can take a while before a problem becomes evident. However, when this is the case, things can go from bad to worse fast.

That’s why it’s so important to have a good understanding of how HVAC systems work, as well as how to keep an eye on them for problems. Cleaning HVAC coils, for example, is a crucial, yet often neglected task.

If your HVAC coils look like they could use a good cleaning, never fear! With a few simple steps, you can have them look like new in no time. 

Read on to know how to clean HVAC coils.


Turn off the Power of the Unit

Assuming you have an air-cooled condensing unit, you will need to switch off the power of the unit before you can start cleaning the coils. The easiest way to do this is to find the circuit breaker panel and flip the switch for the outdoor HVAC unit.

If you can’t find the panel, or if the breaker is labeled, you can always shut off the power at the outdoor unit itself by pulling the disconnect switch.

Remove the Covers of the Unit

The next thing you need to do when cleaning HVAC coils is removed the unit covers so you can access the coils. This may seem like a daunting task, but it’s actually quite easy.

Simply use a screwdriver to unscrew the screws that hold the covers in place. Once the covers are off, you’ll be able to see the coils and clean them with a soft brush.

Remove Any Dirt or Debris on the Coils

If you want to clean your HVAC coils like a pro, you need to remove any dirt or debris on the coils. The easiest way to do this is to use a vacuum cleaner with a hose attachment.

Vacuum the coils from the inside out, being careful not to damage the fins. Once the coils are clean, you can use a coil cleaning solution to remove any stubborn dirt or debris.

Rinse Them With a Garden Hose

If you want to give your HVAC coils a good rinse, you can do so with a garden hose. Before rinsing it, make sure that the water pressure on your garden hose is not too high.

High water pressure on your garden hose might end up damaging the coils. Also, be sure to double-check that the unit is not connected to any power source to avoid any short-circuiting.

Apply a Coil Cleaning Solution to the Coils

Finally, apply a coil cleaning solution to finish it off. You can either buy one or make a homemade solution. If you bought one, make sure to follow the manufacturer’s instructions when applying the solution.

You will need to let the solution sit on the coils for a period of time before rinsing it off. Be sure to rinse the coils again thoroughly to remove all traces of the solution.

If any problems persist, call HVAC professionals just like this here for high-quality services.
