Best coil cleaner for air conditioner 2023-Complete Buying Guide

When it comes to air conditioner maintenance, one of the most important tasks is to regularly clean the coils. Coils can become clogged with dirt and debris over time, reducing the efficiency of your cooling system and causing potential damage. That’s why it’s so essential to use a good coil cleaner to keep the system performing optimally.

This buying guide will help you find the best coil cleaner for your needs in 2021. We’ll explain what criteria you should pay attention to when shopping for one, describe the different types available, provide some helpful product recommendations and explain how proper maintenance with a coil cleaner can prolong the life of your air conditioner. By following our advice in this guide, you’ll be able to pick out a high quality cleaner that will help ensure that your AC keeps cooling properly for many years to come!

Brief explanation of air conditioner coils and their importance

to Source

Air conditioner coils are integral components of HVAC systems, and they’re responsible for cooling the air that is circulated within a home or building. Generally located in the blower compartment within an air conditioning unit, these coils contain tiny tubes that allow refrigerant to flow through and absorb heat from the surrounding air. Coils then radiate this heat outside of the unit through a process of condensation.

Over time, dirt, dust, grass clippings and other airborne particulates can settle on the coils decreasing its ability to properly cool the air. This can lead to decreased energy efficiency and eventual malfunctioning of the system which may require costly repairs. To prevent this from occurring, regular maintenance involving coil cleaning should be practiced on a routine basis. Coils cleaners contain chemicals formulated to remove stuck-on debris without damaging any part of the system so it’s essential that you understand what type of product you need before using it on your AC unit.

Overview of the importance of cleaning the coils

The coils in an air conditioning system play a vital role in cooling the air, as they are responsible for absorbing heat from the indoor environment and then releasing it outdoors. In order for the system to run effectively, these coils must be kept clean. Over time, dirt, dust, and other debris can accumulate on the coils, reducing their ability to absorb heat. As a result, the air conditioner need to run longer in order to cool the home – creating higher energy costs each month.

Cleaning your system’s coils is one of the simplest yet most effective ways of increasing efficiency while reducing energy bills significantly over time.

Purpose of the guide

The purpose of this guide is to provide air conditioner owners with information regarding the best coil cleaners for their needs in 2023. Coil cleaning is an important aspect of AC maintenance, as it helps reduce energy consumption and extend the lifespan of your unit.

This guide will discuss the different types of coil cleaners available, their advantages and disadvantages, how to use them properly, what to consider when selecting a cleaner, and provide our readers with helpful cleaning tips. By the end of this guide, you should feel confident in selecting a cleaner that is suitable for your air conditioner.

Factors to consider when choosing the best coil cleaner

to Source

When buying a coil cleaner to meet the needs of your air conditioner, there are several factors that you should consider. Below is a list of things to keep in mind when selecting the right coil cleaner:

  1. Type of coil cleaner: The type of coil cleaner that you choose for your AC system will depend on the material that your coils are made out of, as some cleaners may be suitable for one material and not another. Carefully read all instructions before purchasing a cleaner to ensure it is appropriate for use with your current setup.
  2. Coverage: When choosing a coil cleaner, you will want to ensure that it can provide sufficient coverage over the surface area of your coils so that they are properly cleaned and degreased.
  3. Safety: You should always make safety a priority when selecting any type of chemical cleaning product or device, and this is especially true when choosing one for use with an air conditioner. Consider whether or not the product has any warnings or safety hazards associated with it before purchasing it, as those could be potentially damaging to both you and your unit if not taken into account properly beforehand.
  4. Effectiveness: Of course, you will also want to look into how effective a cleaner is in removing dirt and degreasing coils prior to making a purchase decision; make sure any product you buy is up to task in providing satisfactory results every time you clean it off!
  5. Cost/Value Ratio: Finally, think about cost versus value when selecting a new AC coil cleaner; often times when looking around for options that fit within budget constraints, cost-effectiveness can become an important factor in decision-making processes!

Type of coils (aluminum, copper, etc.)

When considering a coil cleaner for your air conditioner, it is important to choose the right product for your unit’s type of coils. The most common types of coils used in air conditioners are aluminum, copper and tin-plated steel. Each of these coil materials require different cleaning methods and products in order to maximize the efficiency and life-span of your system. Taking the time to identify which type of coils you have will help you choose the most suitable cleaner for your air conditioner.

  • Aluminum Coils
    • Aluminum coils are one of the most common types of coils used in air conditioners. They are also some of the easiest to clean as they require less aggressive agents than other materials. This means that basic cleaners such as diluted dish soap or window cleaner can often be used to remove dirt and debris from aluminum coils with minimal effort.
  • Copper Coils
    • Copper coils are considered to be more efficient than aluminum, though they can corrode faster due to their higher electrical conductivity compared with other types of metal used in air conditioners. As a result, it is important that you select a coil cleaning agent which is suitable for use with copper coils as using an unsuitable product can lead to permanent damage done both the unit’s efficiency and lifespan. It is best practice to use a non-abrasive cleaner specifically designed for cleaning copper surface when dealing with this type material in order for it remain functional for longer periods without replacement or repair work required on it sooner than expected due its sensitive nature.
  • Tin-Plated Steel Coils
    • Tin-plated steel feature both good conductivity as well as corrosion resistance qualities which makes them among some varieties preferred over others when building an AC unit today comes into mind while many companies continue opting them due their cost effective nature even after alternative metals have been made available at present. Despite their innate ability withstand corrosion better than others lighter metals based types, these blades should still be given considerable attention by users along with any other variety into confirmation that they get properly maintenanced on regular basis so remain protected while avoiding any unwanted issues cropping up further down line even after good amount usage occurred over time. Same rule applies when attempting select appropriate methods products require during clean up process since just like copper varieties sn wrong object can end causing significant harm rendering entire setup useless if efforts done correctly following all necessary steps suggested experts garnered through years experience would help guarantee one giving off optimal performance without fail if all outlined tasks stepped performed accordingly from start finish.

Strength of the cleaner

One of the most important factors to consider when buying a coil cleaner for your air conditioner is its strength. Some cleaners are designed for heavy-duty jobs and require users to dilute them before spraying. Others are designed for lighter duty applications and can be used at full strength.

It’s important to select a cleaner that adequately matches the desired task.

Another factor to consider is whether or not the cleaner contains solvents that could damage your air conditioner’s components. Some solvents can strip away important lubrication on metal and plastic components, which can cause them to wear out quickly or become damaged altogether. Always read the product label closely before purchasing a coil cleaner and ensure that it’s safe and compatible with your specific model of AC system.


Safety is a crucial factor to consider when choosing and using coil cleaners for air conditioners. Since most coil cleaners contain hazardous chemicals, always make sure you’re using them in a well-ventilated area with personal safety gear like safety glasses, gloves, and a respirator. Though some products do not contain harsh chemicals, it’s still important to take the necessary precautions when applying any kind of cleaner.

Before starting the coil cleaning process, make sure that your unit is disconnected from the power source and read all directions thoroughly. Using too much cleaner or leaving it on for a too long duration can damage your unit and result in worse system performance than before. Avoid excessive contact with skin and eyes while spraying or rinsing off the coil cleaner.

Before re-attaching your air conditioner system to electricity source after cleaning its coils, make sure that the surface of evaporator coils are completely dry to avoid any electric shock hazard or short circuit issue.

Ease of use

When selecting a cleaner for your air conditioner’s coils, first consider the amount of time and effort it will take to use it. Many coil cleaners will require you to brush and manually scrub the coils, while others may utilize foaming technology that allows the cleaner to cling to the coil surface long enough to be effective. Not only is this more efficient, but it can also minimize environmental waste compared with aerosol-based products that must be applied multiple times.

Additionally, many foaming cleaners are designed for applicators with minimal maintenance requirements—allowing for quick and easy applications with less mess.

Environmental impact

The environmental impact of a coil cleaner needs to be considered when making your choice. Coil cleaning agents are typically volatile organic compounds (VOCs) or petroleum-based or chlorinated solvents. They can have a negative effect on indoor air quality, so choosing an effective and less damaging cleaner is important.

Look for “green-certified” coil cleaners which are made from natural, biodegradable ingredients such as plant extracts and citrus oils. These products are often safer for human health due to their low levels of VOCs, and many are nonflammable and nontoxic to aquatic life. Additionally, aerosol-free product delivery systems reduce VOCs in finished air systems by containing product inside the unit and not spraying it into the atmosphere.


For 2023, the choice of an ideal coil cleaner for your air conditioner depends on your priorities and budget. Foam coil cleaners are longer lasting, but may be too harsh for some situations. Gel cleaners are easier to use and offer less abrasivity, but you may need to apply them more frequently. Finally, aerosol foam coil cleaners offer the perfect blend of convenience and ease of use but have a limited lifespan.

Ultimately, it is up to you to decide which option best suits your needs this year and beyond!

  • Foam coil cleaners – longer lasting, but may be too harsh for some situations.
  • Gel cleaners – easier to use and offer less abrasivity, but you may need to apply them more frequently.
  • Aerosol foam coil cleaners – offer the perfect blend of convenience and ease of use but have a limited lifespan.
