How To Clean A Coleman Mach AC 

You can proceed to DIY cleaning your Coleman MACH AC by following this step-by-step guide:

1. Prepare The AC Unit

Turn off the AC system and unplug it before starting the cleaning process. When it's safe to continue, remove the two 1/4-turn fasteners holding the grille attached to the ceiling assembly. Remove the grille and take the filter out.

2. Use A Vacuum To Clean The Filter

A vacuum is a good option for cleaning your AC filters as it sucks and pulls out all the dirt and dust inside. Be mindful not to apply too much suction to avoid damaging the screen.

For other filters with regular maintenance, cleaning requires nothing more than a vacuum. However, for those that are not regularly maintained, they may cost you more time. If that's your case, follow the remaining steps below for deep cleaning.

3. Soak And Scrub The Filter

In a large bucket, submerge the filter in warm water for 10 to 15 minutes. Filthy filters require more time and attention. You can run a soft brush through the screen to help remove the dirt and rinse.

4. Use A Vinegar Solution To Prevent Bacteria Growth

Vinegar solution is a natural antibacterial cleanser that will help prevent bacteria growth without causing chemicals in the air circulating inside the room. To do this step, prepare a 50/50 mixture of water and vinegar into a spray bottle.

Spray the vinegar solution evenly on the filter's two sides and let it sit for around 15 minutes. Then wash the screen once more so that when you turn your unit back on, it won't smell like vinegar.

5. Wipe The AC Unit With A Clean Dry Rag

Another important part of cleaning is to clean the external parts of your AC. Make sure to use a clean dry rag in wiping its parts to prevent damage that may be caused by wet particles.

6. Dry The Filter Before Putting It Back In Place

Because of the materials used in making AC filters, they may take several hours to dry. Once the filter is completely dry, carefully put it back into place. Reinstall the grille, push back the fasteners and you're good to go!

Routine Maintenance for your Coleman MACH AC

Broken RV air condition unit repair

Cleaning your Coleman MACH AC including its filter regularly can improve the unit's performance and reduce the need for expensive air conditioner repairs. It is recommended that the filters be cleaned at least every 2 weeks when the air conditioner is in use. More frequent cleaning is needed for people with allergies and respiratory conditions. 

Advantage Of A Clean AC Filter

Like any other appliance in your house, a clean AC filter benefits us in many ways. First and foremost, the filter secures the air conditioner by filtering dirt and dust that, if not removed, would clog the air handler and make your AC unit work harder to chill the air. This lot of work put on the AC's refrigerant can cause damage to the unit.

A clean AC filter also provides relief for people suffering from respiratory problems including allergies because it improves the quality of the air circulating around the room.

How Often Do You Change RV AC Filter?

Air flows continuously through your RV AC while it's operating. A filter system is used by air conditioners to prevent the entry of dust and filth. You should change the filter after 150 to 400 hours of use depending on your place and usage.

If you live in a dusty place or where there are a lot of pets, then you should change the filter after 150 hours of use. On the other hand, if you rarely use your AC and live in a place where there is less dust, then you can wait up to 400 hours of use before replacing them. To extend the life of your air filter, you should clean it every 30 days regardless of how less you used the unit.

How Do I Reset My Coleman Mach AC?

There is nothing worse than having a malfunctioning AC on a hot summer day. Resetting the unit is one good option to help the unit get back on track. Follow the steps below to reset a Coleman Mach AC:

  1. Switch off the thermostat.
  2. For roughly 5 minutes, take the air conditioner's switch out of the circuit breaker box.

Is It Okay To Spray Water On Your Air Conditioner While It's Running?

The summer season is the time of year when air conditioners are most needed, which means that they would work harder during that period than at any other time. Spraying or splashing water on an air conditioner's condenser unit won't harm it, but it will momentarily improve cooling performance and help clear out any dust or dirt that may have formed due to airflow through the unit.

How Does Spraying Water Help In Air Conditioning Service? 

One common way of cleaning the exterior of an AC unit is by spraying water.

Some people, however, are hesitant to do this since they were taught and are afraid that water and electricity should remain separate. But spraying water occasionally can help the condenser to perform well with the following benefits:

Running more efficiently

The condenser will cool more quickly if water is sprayed on it because the water will evaporate. As a result, the unit uses less energy to chill the area, saving you money on energy.

Increased Lifespan

The unit's lifespan increases since it has less work to do. Also, it is advisable that you clean the filters every 60 to 90 days to prevent them from clogging. Filthy filters can give you headaches and can cause issues on the unit.

Maintaining the cleanliness of the unit

Dust and other particles can build up on the vents of your AC unit making it the more reason to spray water on it to remove unwanted particles from clogging. The more dirt clinging to the outside of your AC unit, the dirtier your filter gets.

If the filter gets dirtier, then it will no longer catch all the dirt. It will cause some particles to clog the unit which can lead to more expensive repairs and replacements.
