How To Differentiate Evaporator And Condenser Coils

Wondering, “What’s the difference between ac evaporator vs condenser coils?”

An air conditioner is a heating and cooling machine that removes moisture from the air and keeps the living space cool in summer. There are two major components that make up an air conditioner: the condenser coil and the evaporator. Both components have their own purpose. 

The condenser coil is responsible for cooling down the refrigerant while the evaporator pumps out heat into the room. If you are looking to replace either component, it is important to know what they do individually so you can choose the right replacement part.

So what are they? And how do they differ?

In this article, we’ll explore the differences between AC evaporator vs condenser coils and how they work together to keep you cool in any environment. Moreover, we’ll also cover some common problems of both of these types of coils and a few maintenance tips to keep them up-to-date.

So, let’s get started.

What’s an AC Evaporator Coil?

The evaporator coil is one part of a split system air conditioner, which means it works with another component—the condenser coil—to cool your home or office. This type of system uses refrigerant to create cold air that is distributed throughout your space through vents.

The evaporator coil sits outside your property and draws hot air from your home or business. It then converts this warm air into the cold by passing it over a refrigerant-filled core, which brings down its temperature until it reaches levels that can be circulated throughout your living space via ductwork.

How Does An AC Evaporator Coil Work?

The AC evaporator coil is one of the most important parts of your air conditioning system. It’s responsible for cooling down the air in your home or business, which makes it an essential part of keeping your home comfortable. The evaporator coil is installed inside an air handler, which is a small box that sits outside your home and contains all the parts necessary to power your HVAC unit.

There are two different types of AC evaporator coils: electric and gas. 

  • Electric coils are powered by electricity and are used in homes with central air conditioning systems. 
  • Gas coils use natural gas or propane to power them, and they’re usually found in commercial buildings that don’t use electric coils.

The way this part works is pretty simple: It helps remove heat from inside your home by circulating cold refrigerant through it. A fan blows warm air into the unit, which then passes over cool metal fins on the evaporator coil before being blown out into the room again. This process creates a continuous cycle of hot air being pulled into the unit, cooled down by refrigerant inside it, and circulated back out into rooms where people live or work.

What Is AC Condenser Coil?

AC condenser coils are a type of heat exchanger that is used in refrigeration and air conditioning systems. They are also known as evaporators.

They are responsible for transferring heat from the inside of your home to the outside in order to cool it down. This transfer is done through the evaporation of a liquid refrigerant.

How Does AC Condenser Coil Work?

The condenser coil is a vital part of your air conditioner that helps the system achieve proper cooling.

The condenser coil is located outside the home, usually attached to the side of the house or in an attic. The heat from inside your home is transferred to this coil via refrigerant, which causes the liquid to evaporate and release heat into the air. This process is known as phase change. The hot refrigerant then travels through a series of tubes to the compressor, compressing it into a smaller volume and increasing its pressure. This allows for more heat to be released into the air as well as provides cooling for your home.

If you notice that your AC isn’t cooling your home effectively or if it seems loud when it’s running, this could be an indication that something is wrong with your condenser coil. If this happens frequently, it may be time to call an HVAC expert for condenser coil replacement instead of repairing it because repairing can be more costly than replacing entirely.

Quick Differentiation Between AC Evaporator VS Condenser Coil

There are many homeowners in Hurricane, WV, who are confused about the difference between AC evaporators vs condenser coils. This is because these two components look similar, and their functions are almost the same. However, it is important to understand that these two components have some differences.

Common Problems Of An HVAC Evaporator Coil

Your HVAC evaporator coil is essential to your heating and cooling system. It’s the part that transfers heat from the air in your home to the refrigerant, which then carries that heat away.

If your evaporator coil isn’t working properly, it can cause a variety of problems. Here are some common issues you might encounter:

Coil Freezing

The first problem that can be caused by the evaporator coil is freezing. The reason for this is because there is a lack of circulation in the air, which causes the coil to freeze. This can be easily fixed by adding more air circulation to the system to help prevent freezing from occurring.

Coil Corrosion

The second problem that can be caused by an evaporator coil is corrosion. Corrosion occurs when water or moisture gets inside the tubing and freezes, which causes it to expand and crack. This can cause damage to your home’s heating system and should be addressed immediately if it happens in your home!

Refrigerant Leaks

A refrigerant leak is one of the most common problems that can occur in an HVAC evaporator coil. Over time, the coil can develop small cracks or holes, leading to refrigerant leakage. This not only reduces the cooling capacity of the system but also puts additional strain on other components. If you notice a decline in cooling performance or hear hissing sounds coming from your unit, it is essential to have a qualified Hurricane HVAC technician inspect the evaporator coil for potential leaks.

Restricted Airflow

Restricted airflow is another issue that can affect the performance of the HVAC evaporator coil. It can be caused by clogged air filters, blocked vents, or dirty coils. When airflow is restricted, the coil may become overloaded, leading to reduced cooling efficiency and potential system breakdown.

Coil Fin Damage

The coil fins are delicate metal blades that surround the evaporator coil. They enhance heat transfer by increasing the surface area. However, these fins can easily get bent or damaged, affecting the coil’s performance. Bent fins can disrupt airflow and reduce the coil’s ability to extract heat efficiently. If you notice bent fins, it is crucial to have them straightened by a professional Heat Pump technician in Hurricane, WV, to restore optimal performance.

Mold and Biological Growth 

If there is enough moisture in your home for mold to grow on your evaporator coil, it can be very dangerous for pets and humans. The spores produced by mold can irritate the lungs and cause asthma attacks in those who are sensitive to them while also making everyone else sick if they aren’t careful with their cleaning methods during repairs or replacement jobs like these!

Coil Dirt and Debris Buildup 

This is the most common problem with evaporator coils. When dirt and grime build up on them, they become less efficient at removing heat from your home. This causes your air conditioner to work harder, which can result in higher energy bills.

Improper Sizing or Matching

HVAC systems are designed to work efficiently when the components are properly sized and matched. If the evaporator coil is not correctly sized for the system or is mismatched with the condensing unit, it can lead to operational problems. These problems may include inadequate cooling, reduced efficiency, and increased wear and tear on the equipment.

Common Problems Of Air Conditioning Condenser Coils

Have you noticed a decrease in the efficiency of your air conditioning system? The first step to getting this problem solved is to understand exactly what is causing your Air conditioning condenser coils to fail. In this section, we’ll take a look at some common problems that can lead to decreased efficiency and a higher electric bill.


This is one of the most common problems with air conditioning condenser coils. It can happen in two ways – either through direct contact with water or through chemical reactions that occur due to exposure to high levels of humidity or salt concentrations. The corrosion can lead to a decrease in efficiency and an increased risk of failure of the coil.

Dirt and Debris

Dirt and debris on an air conditioning condenser coil can interfere with its ability to cool down properly, leading to overheating, which can cause severe damage to other parts of your system as well as create unpleasant odors in your home or office space.

Clogging and Blockages

The condenser coil can suffer from clogs and blockages along with dirt and debris. These can occur due to the accumulation of debris or the presence of pests, such as insects or small animals. Clogs and blockages restrict airflow and can cause the system to work harder, leading to decreased performance and potential damage to the compressor.

Bent or Damaged Fins

The thin metal fins surrounding the condenser coils are susceptible to bending or damage due to various factors such as harsh weather conditions, accidental impact, or improper maintenance. Bent fins obstruct the airflow, obstructing the heat exchange process and reducing the air conditioner’s overall performance. It is essential to straighten or replace damaged fins to ensure unobstructed airflow and optimal cooling efficiency.

Inadequate Maintenance

Air conditioning systems, including the condenser coils, require regular maintenance to function optimally. Neglecting routine maintenance tasks such as cleaning, lubrication, and inspection can lead to various problems, including reduced cooling efficiency and increased energy consumption. Following a maintenance schedule recommended by the manufacturer will help identify and address potential issues before they escalate.
