The air conditioner is one of the top modern developments. With a rise in temperatures all over the world, it has become a staple in many homes with many people choosing this as their preferred method of regulating the temperature in the summer.
Unfortunately, the air conditioner does have some maintenance that goes along with it and you will need to keep it in the best possible condition to have it working smoothly and effectively. While there are many parts to an air conditioner, the AC coils are essential to the cooling process and need to be cleaned and maintained effectively.

The Main Purpose of the AC Coils
AC coils are broken into 2 different types. The evaporator coil is the main part responsible for giving you cool air. Air also goes through the condenser coils which is the second part of the cooling process. Despite what many people believe, the air-conditioner does not cool the air. It actually just removes the heat from the air.
The evaporator coil will extract the heat as it passes through and then, through the help of a refrigerant, enable you to have cold air. The heat is extracted and released outdoors while your home is kept cooler. The fan that is included on top will blow the hot air over the condenser coils and this releases some of the heat from the refrigerant before it is passed outside. These two coils need to remain in optimal condition for your air conditioner to have an effective cooling process.
Operating Your AC Unit with Dirty Coils
One of the biggest mistakes you could make is using your AC unit with dirty coils. One of the first problems that you will have is a lack of cooling in the home and the coils will not be able to effectively extract all of the heat. The only way to have your air conditioner work effectively is to make sure the coils are kept clean and free of contaminants.
The dirt or contaminants will eventually act as a barrier to the coils and this keeps the heat from escaping. It might also lead to drainage problems but fortunately, it can be fixed quite easily. After the coils have been cleaned thoroughly, your AC unit will be working as if brand new. Cleaning should be done often to ensure that the dirt does not build up.
Characteristics of a Good AC Coil Cleaner
When searching for a good AC coil cleaner, there are a couple of things that you need to keep in mind. With so many options available, it can be a daunting prospect to find the right one. Here are a couple of things that you should look for in a great coil cleaner:
- Alkaline-based: Acid based products are commonly found in many cleaning products. The acid will clean your coils, but dirt on coils can be rather stubborn and the acid could damage the coils. Most AC manufacturers will recommend using only water, but a gentle alkaline-based substance can also work.
- Usability: The product should be easy to apply and you should not need to have to put in too much effort. If an additional sprayer is included, this will make the application process much easier and you need not worry about applying too much of it.
- USDA Authorized: If a product is U.S.D.A. Authorized, it means that it will be safe to be used near food. This also means that you need not worry about any poisonous substances that could cause problems for your health either.
- Price: Some cleaners specifically designed for cleaning AC coils can be more expensive than the general-purpose cleaners you are used to. Fortunately a little can go a long way.
- Versatility: While you might only be using this cleaner once every now and again for your coils, you should seek something that can be used elsewhere as well. This gives you more versatility and makes it that much easier for you to use the product on removing dirt and grime elsewhere.
- No harmful additives: Chlorinated solvents are quite harmful to the environment and while they do the job of cleaning a little faster and better, it does not bode well for your health. While it can be hard to find something completely green, you should consider something ozone-friendly.
When it comes to cleaning substances, it can be hard to specifically say that certain ingredients are better than others are. One of the main things you need to keep in mind is the safety. You should check the labels for safety information and whether the product can be damaging to your health as well.
Is This a DIY Job?
Cleaning your condenser and evaporator is a job you can do yourself, but it requires a lot of care. Be careful not to bend the fins of the coils or to break, move or bend any of the tubes around. Of course, it’s always important to shut off your air conditioner first to avoid the danger of electrocution!
However, if you’re not comfortable with this, or fear damaging your system, make an appointment with an HVAC contractor. It would be great to get a maintenance contractor that includes this service as well!

Air conditioning cleaners are effective at helping you do this and they are highly recommended by AC specialists as well.
