Symptoms of a Dirty Evaporator Coil: How They Affect Performance

Evaporator Coil: How They Affect Performance

If you have noticed that your AC unit is not performing as well as it used to, there might be a good reason for this. A dirty evaporator coil can affect the performance of an AC unit in many ways. You can use an Evaporator Coil Cleaner to fix this issue. This blog post will explain what symptoms to look out for and how dirty coils can impact your AC’s performance. It will also provide tips on how to clean these coils, so they are running at peak condition again! Let’s discuss them in detail!

Symptoms of a Dirty Evaporator Coil

There are many symptoms of a dirty evaporator coil. Sometimes you might not notice any changes in the performance. If so, it’s extremely important to clean these coils regularly. Not cleaning them can lead to some major problems that will be explained below!

The first symptom is that your AC unit emits an unusual smell when running, although it doesn’t happen very often with modern units. The reason for this is because there could be bacteria and mold inside the system, which grow more at higher temperatures created by AC units. This musty smell gets worse during humid days or seasons too! You should consider getting someone who specializes in HVAC systems to check out your equipment as soon as possible if you notice this problem occurring more often.

Another major symptom will be that your AC unit freezes up or ice builds up on the coils, which can lead to your equipment not running at all! This is because the buildup of minerals and dirt causes a blockage in liquid flow inside the system, so it creates an overload situation for the water pump resulting in freezing pipes. The best way to prevent this from happening is by regularly changing out your filters as air flows through them first before reaching any other components. You must also check if there are any leaks with hoses, connections, etc.


How They Affect Performance

Having an iced-up evaporator coil can reduce the airflow in your unit, which will cause it to work harder. If this happens, then you’ll notice that your home is not cooling as well or that you are getting more noise coming from the system during operation.

This might also lead to additional wear and tear on parts like fans, blowers, compressors, among others, since they’re working overtime with little to no relief for them while trying to get rid of heat. In order to avoid these issues, HVAC professionals recommend Evaporator Coil Cleaning once a year just before summer kicks off so that there won’t be any added stress on equipment leading into high usage months when people turn their units on full blast!

After all, nobody wants to pay for repairs or replacements of HVAC equipment before summer!

How Can You Clean A Dirty Evaporator Coil?

You can clean these coils to increase the performance of your AC. There are professionals who can do this for you but if you’re looking to save some money, here are the steps that will help:

  • Shut off the power supply of equipment before attempting cleaning procedures
  • Start by removing fan blades and clean them thoroughly with a soap water solution.
  • Spray anti-rust agent on all exterior parts that come into contact with refrigerant or oil (like fans)
  • Clean all the dirt and dust with a vacuum
  • Spray anti-rust agent on all exterior parts that come into contact with refrigerant or oil (like fans)
  • Clean the coils. You can use water and baking soda for this purpose, but it is very important to let the solution dry before using any AC equipment again! If you don’t have enough time, there are many service providers who offer Cleaning evaporator Coil at great prices! That way, they will take care of everything without needing too much effort from your end!

Now, here is what you should know when scheduling a maintenance appointment! While asking how often technicians recommend having evaporator coils cleaned, be sure to ask these questions, too, so there won’t be any disappointments later on.

When Do You Need to Replace Your AC Evaporator Coil?

In some situations, you need to replace your AC evaporation coils. Some of the situations are:

  • Old coils
  • Severely rusted coils
  • Corroded or broken coil fins
  • Leaking evaporator manifold gaskets.

Evaporators are the devices that produce cold air for your AC system. Dirty, leaky, corroded, or damaged evaporation coils can cause serious problems to the performance of an air conditioner!

Evaporation coils have a great impact on how efficient and effective the compressor runs in order to cool down your home. When it comes time for furnace repair, you need someone who has hands-on experience with all brands of AC units. It is very important to detect any problem at its early stage because small issues can turn into big ones if not taken care of immediately.


I hope this blog has been informative and helpful. The information here about AC evaporator coils is also crucial in maintaining your home for a long time to come! If you are facing any other issue with your HVAC system, it’s better to get some help from some experts in this field.
