Do you want to know how to clean your air conditioner parts? We all like the cool air and comfortable atmosphere the air conditioner provides. But in summer, if the filters and the inside of the A/C aren’t cleaned up, it converts less effective and more heated up. Is such a thing worth spending plenty of money over when you can take care of it yourself, at home?

With a few easy steps, you can make sure that your air conditioner is clean and ready to keep you cool in the burning heat of summer, just in time!

How to Clean Your Air Conditioner Ducts

This is apparently the messiest part of cleaning your air conditioner. After all, all the dirt, dust, debris, fungi, and bacteria are usually found in the air ducts. This is typically the problem with central air conditioners (skip ahead if you haven’t installed air ducts in your house).

Don’t worry, we’ll guide you on cleaning your HVAC ducts without making a mess of your home.

1. Cover the Supply Registers and Home electronics

Utilize plastic sheets to cover electronics such as desktops and televisions.

Next, apply a few cleaning cloths to the cover and check all the supply registers (vent covers). This is to block dust and dirt from getting blown into your rooms.

2. Turn on the Fan

This will assist loosen and blow all dirt and dust from inside the ducts and onto the duct openings for easier cleaning.

 3. Open and Clean the Supply and Return Registers 

Make sure you’ve switched off the fan and your air conditioner. Next, open the supply and return registers and clean all the dirt accumulated there.

Use your long-handled dust brush to reach under into the ducts and pull in all the dust and dirt. Then, use your vacuum cleaner to absorb it all in.

4. Clean the Air Ducts

First, apply your long-handled dust brush to move as far as you can and clean the air ducts. Next, apply your heavy-duty vacuum cleaner (preferably with a long hose) to suck in all the dust and dirt. Then, dip your cleansing cloths in soapy water and brush as far into the ducts as your hand can reach.

5. Replace the Furnace Filter

You’re advised to replace your furnace filter at least once a year (this is your turn). Sometimes the dirt build-up might be too much and forever clog the filter.

Finally, give the components to dry and carefully put together the air ducts. Remember to keep your electronics covered from dust.

How to Clean Your Air Conditioner Coils

You might not know this, but it’s at the coils where everything appears. The Air Conditioner Coils contain the refrigerant that is capable of cooling your indoor air. Your AC first sucks in the hot indoor air and gives it over the coils. The refrigerant in the coils then receives the heat from the indoor air. The cool air is then shifted back into the room.

Dirt and dust build-up on the coils will decrease your air conditioner’s efficiency. The layer of dirt will insulate the coils and hinder the refrigerant from receiving heat. This will force your air conditioner to utilize more electricity. The result is high electricity bills.

1. Gain Access to Your Air Conditioner’s Coils

First, switch off your air conditioner and also make sure the electricity is switched off. For Window Air Conditioner Units, the coils are normally located at the back (the part that is outside your window/ inside the wall). Track your AC’s manual and unfasten the cover using the screwdriver.

You might have to unmount the unit from the window to avoid forming a puddle of water outside your window. For Central Air Conditioners, their position will alter with each model. Check the AC’s manual.

2. Inspect and Brush the Coils and Fins

Before you start cleaning, open your eyes and examine the coils and fins for any sign of damage.  Next, apply your hand to pick out and remove large colonies of mold, dust, and dirt debris.

After that, pick up the coil brush and wash motion that is parallel to the fins found on the coils. This will help straighten out fins that might be somewhat bent or out of position. Be firm but careful.

3. Rinse the Coils

Take your garden hose and rinse the coils with water at average pressure. This will help remove any leftover dirt particles.

4. Apply the Foaming Coil Cleaner

Please note that there are two main kinds of foaming coil cleaners:

  • Standard cleaners
  • Modern cleaners that don’t need you to rinse after application

Shake the bottle and apply straight onto the coils and fins. Its foaming property will allow it to squeeze into spots where your cleaning water couldn’t reach.

You must apply the foam until the coils are fully covered and out of sight. Next, leave the foam for 15 minutes.

5. Rinse and allow the coils to dry

For standard coil cleaners, you’ll have to rinse after application and let the coils dry before assembling your unit. Rinse in a motion parallel to fins to check the hose water from bending them.

For the latest coil cleaners, there is no need to rinse. Wait for the foam to dry up and compile your AC. You’ll be amazed how clean your air conditioner’s coils can drastically improve its efficiency.

How to Clean Your Air Conditioner Filter(s)

Filters deserve more credit than they get. You have no idea just how great filters are in your home. We already mentioned earlier just how nasty your indoor air could be with all that dirt, bacteria, fungi, and pet fur.

Filters are the primary tools responsible for cleaning your indoor air.

In addition to that, filters ensure that dust and dirt don’t reach other internal components (like those coils you just cleaned).

1. Open your AC to Access the Filter(s)

First, learn to switch off your air conditioner and unplug it from the power supply.

Enter through your AC’s manual to know where the filter is located and whether or not they’re more than one (usually the case with central air conditioners). You can also search for a YouTube video that is precise to your AC’s brand and model.

Next, apply the screwdriver to open the cover or untie the filter(s). It’s also essential to confirm whether or not the filter is replaceable. Normally, reusable (non-replaceable) filters have metal or plastic frames. In this case, you’ll have to clean them.

Replaceable filters are usually embedded with cardboard frames (Remove and replace them with new filters). Pay attention to the filter’s size not to buy an incompatible filter with your air conditioner.

2. Inspect the filter

Check to notice if your filter might be damaged, corroded, or with any sign of wear. Replace your filter if you spot any of these mistakes.

3. Clean the filter

First, use your hand-held vacuum cleaner to suck in all the dust and debris from the filter. Next, take the filter to your bathtub or sink and use faucet water to eliminate any leftover dirt. Make sure to wash it face down in the direction reverse to airflow.

4. Allow the filter to dry

Place it out in the open below natural light and heat. Too much heat, and you’ll damage it. You can apply your hairdryer at a medium setting to quicken the method. Make sure to flip the filter every 10 minutes until both sides are fully dry.

You should also check on your air conditioner’s filter at least once every month, particularly if you live in hot and humid areas that are prone to mold infestations.

Is it OK to spray water on your room air conditioner?

Yes, you can spray water on your air conditioner if it needs a cleaning, and nothing terrible will happen. Spraying water on your AC’s condenser also supports it run more efficiently. Your condenser needs regular spritzing to keep doing a good job.

What happens if AC is not serviced?

If you do not do the regular aircon servicing, then dirt and dust will get deposited in its filters. This deposition of dust and dirt in the filters affects its working, and your air conditioning system will need to invest more effort in its working.

Can I use vinegar to clean AC coils?

Take your spray bottle, vinegar, and water. Mix half water and half vinegar inside the bottle. Shake the solution well, and employ it to the evaporator coil and condenser coil. Vinegar will not hurt the parts and is a very effective cleaner.
