AC Coil Cleaners Buying Guide

You will always want to ensure that you are buying the best of the best when it comes to cleaning agents or products for anything in your home. This applies to your air conditioner and the coils that you would need to keep clean. Here is everything that you want to know about buying the right AC coil cleaner for your needs.

The Importance of Keeping Your AC Coils Clean

There are plenty of reasons that you want to keep the coils of your air conditioner clean, but the biggest one is that it will be much more efficient. If you are cleaning the outdoor coils, you will ensure that all of the debris and dirt that would be blocking the filters are cleaned. This will help save money over time, and you would be able to keep your machine running for a longer period of time if it is properly maintained.

DIY or Hire a Pro

You might be thinking about whether or not you will be able to clean the coils yourself or if you need to hire an expert. However, there a few options that you can consider, including:

  • How to clean a/c coils – Depending on the type of product you have, you can either spray it directly on the coils as is, or you would need to dilute it down. Once you have the product ready, you need to spray it onto the coils and then let it sit the required time. After the time has elapsed, which can be around 10 minutes or longer, then you either need to rinse it off or turn the machine on depending on what the directions say.
  • How to clean condenser coils – You will want to ensure that you are looking at the coils and seeing just how dirty they might be. If there are large debris that you can see on the outside, then go ahead and brush those off. After that, you want to straighten out the fins and spray the product directly onto the fins. This needs to sit for around 10 times; then, you can rinse the fins down if necessary.

However, there can be some problems with cleaning them yourself, especially if you don’t have the time. Make sure to consider if you will do the maintenance yourself or if you want to hire the experts to handle it.


How to Clean Evaporator Coils

If you have already purchased your AC coil cleaner, you will need to get that ready. However, you can do this with some warm water and some mild detergent if you don’t. Here are some steps that you need to take to help you clean the evaporator coils properly, including:

  1. Getting your product or detergent and water solution ready
  2. Applying the solution directly to all of the evaporator coils
  3. Wait a few seconds or minutes before it can soak in and start to loosen up the debris, and apply if required
  4. Wipe down the evaporator coils of the loose materials using a brush or soft cloth

This process should be done every few months and especially at the beginning of the summer and winter. Ensure that if you are doing these steps and the evaporator coils aren’t coming completely clean, you will repeat them as many times as required.


Types of Coil Cleaner

Another thing that you need to be aware of is the various types of coil cleaners available. The more you know, the easier it will be for you to decide which one to go for. Some of the types include:

  • Acid-based – This one is made using Hydrofluoric acid, and it shouldn’t ever be used in any indoor system, including chilled water or evaporator coils. This should also be used for outdoor usage for air-cooled condenser cleaning.
  • Alkaline – This has sodium hydroxide or Potassium as the main active ingredients. These should be rinsed off fully when used in any AC system to ensure that the coils and the entire system aren’t damaged.
  • Evaporator – These are non-toxic and non-corrosive, and they are great for being used for indoor systems. These are often either in foam base products or concentrates so that you can water them down before usage.

Ensure that you consider all of these types and choose the one that would work for your needs.


Capacity vs. Cost

Another thing that you are going to want to consider is the cleaner’s capacity versus the cost. Think about how much of the product you would need to clean the system you are using, especially if you are going for the canned products. The majority of the canned products can handle one of the split-level air conditioner systems, while the concentrate will clean the entire household central air system.


Characteristics of a Good AC Coil Cleaner

You want to make sure you are aware of numerous characteristics before you look at the AC coil cleaners. These includes:

  • Alkaline-based – These products are acid-based, and it is often found in a wide variety of cleaning products. The acid can help with getting off stubborn dirt, but it can also damage your coils. This is why you want to consider finding a gentle product that is alkaline-based rather than just water.
  • Usability – You also need to make sure that the product you are looking at will be easy to use and doesn’t require a lot of effort. Think about whether a sprayer will be included since this makes applying it simpler, and you don’t have to worry about overdoing it.
  • USDA authorization – Another thing you need to think about is whether it can be used close to food preparations. If it has authorization from the USDA, it will be safe, and you don’t have to worry about anything.
  • Versatility – You might also want to consider purchasing a product that doesn’t need to be used on coils alone. This is because you would only need to use it once or twice a year, so think about if you can use it on other items in your home to get rid of grime and dust.
  • Price – The final thing that you need to consider and that is the price. These products can end up costing you more than any general-purpose cleansers, so think about the cost. However, for the most part, a small amount of this product can be highly effective.

These are just a few of the main characteristics that you need to consider before choosing any product in the end.


FAQ

  • Why is it important that I clean my AC coils regularly?

If you aren’t cleaning your AC coils regularly, then debris, dirt, and oil will be collecting. This means that the fins on your system won’t work as effectively, which means you aren’t getting as much air in the home, and you are spending more on running it. Also, you would have to replace it sooner than if you were to maintain it properly.

  • How often should I be cleaning my AC coils?

You should make sure that you are cleaning the AC coils at least 1 time every year. If you don’t use the system in the winter, you might want to do it or have an expert inspect the system after the summer.

  • How do I know when I should be cleaning the coils?

If your system isn’t cooling down your house as effectively or as fast as before, you should look at cleaning it. You can order the product in advance and have it on hand so that you can clean it when it starts to get slow. However, you also want to clean it between seasons, especially after winter.


Conclusion

Ensure that you are picking the right AC coil cleaner for your needs, including the price. You also need to make sure that you know how to clean the coils and how often they should be cleaned, which should be around 1 time per year or even between summer and winter. Go ahead and use some of these cleaners to help keep your air conditioner in good condition so you can save money.

My name is Ryan. I have had a hard time dealing with my allergies. Happily, I found that an air purifier was effective to ease my allergy symptoms. I spent a lot of time researching the best air purifier. I know how hard it can be to find the suitable one. During the reading period, I also read a lot about humidifiers and dehumidifiers. I learned the mechanisms behind the technologies as well as the manufacturers and organizations within the industry. I now feel convinced that I have built a guide that shows you all you need to know about air purifiers, humidifiers, and dehumidifiers. So I came up with the idea of creating this website.
