Keeping our home and workplace at the right temperature at any time of the year is not a most straightforward task. Especially in the summer, it can quickly become unbearably warm. That’s why air conditioners are slowly becoming very popular among people.

There are many types of air conditioners. Amongst them, the central air conditioner is a common one. A central air conditioning system is a system in which air is cooled from a central location and distributed to and from rooms.

But which component does cooling? It’s the condenser coil of the central air conditioner. A condenser coil collects the heat from your room and releases it outside.

So are you curious about central air conditioners & their condenser coil? Want to know more about it, like where is the condenser coil located on a central air conditioner? After reading this article, all your curiosity will be gone by learning A-Z about a condenser coil of central air conditioners.

You will also learn about everyday problems and their solutions.

So, Let’s start with a standard overview of central air conditioners & condenser coils.

where is the condenser coil located on a central air conditioner

Where Is The Condenser Coil Located On A Central Air Conditioner?

The condenser coil is located directly behind the condenser “fins” on a central air conditioner.

Fins are mainly thin metal wiring that covers the outdoor AC unit. When refrigerant travels through the outdoor unit, it fills the many condenser coils, increasing its surface area so that heat escapes faster. As a result, condenser coils cool and condense refrigerants.

Significant Components Of Central Air Conditioners And Their Functions

There are four major components of central air conditioners. They are,

  1. Evaporator coil 
  2. Compressor 
  3. Condenser coil 
  4. Expansion valve 

Each of these components functions in sync with each other and has specific work. Apart from these components, there are some other components, such as an air filter, refrigerant, fan, thermostat, etc.

  1. Evaporator Coil

The evaporator coil is located in the air handler in the central air conditioning system. The evaporator coil is mainly made with copper. But sometimes, it is made with aluminium or steel.

Refrigerant is cooled just before entering into the evaporating coil. Then warm air is drawn into the HVAC unit to blow over the excellent evaporator coils. 

  1. Compressor

It’s the most critical component of central air conditioners. The Compressor is the workhorse of central air conditioning. It is located in the outdoor unit of central air conditioners.

It mainly compresses the refrigerants. Based on the size of the air conditioners, the size of the Compressor may vary. It’s the most expensive part of your air conditioner.

  1. Condenser coil

The condenser coil is the opposite of the evaporator coil. The condenser coil pulls away heat from the refrigerant and through it outside. 

  1. Expansion valve

The expansion valve mainly expands the liquid refrigerant into gas after facing a pressure drop, and then it is rapidly cooled. After that, the gaseous refrigerant goes into the evaporator coil to continue the air conditioning system.

Functions Of The Air Conditioner Components

After learning about significant components, it is prudent to know about the function of the major components.

Firstly, the refrigerant is compressed in the Compressor and turned into a hot, high-pressure liquid. Then, the liquid flowed towards the condenser coil and cooled down.

After that, refrigerant is expanded in the expansion valve, which converts the liquid into cool gas. Finally, the cool gas cools down the room. Ok! That is so simple. Right?

Types Of Central Air Conditioners 

There are two types of central air conditioners,

  1. Split system 
  2. HVAC packaged unit 
  1. Spilled system

The split system is for ample indoor space for cabinets. Spilled central air conditioning system holds condenser and compressor in an outdoor cabinet.

On the other hand, it holds the evaporator and handler in the indoor cabinet. Both indoor and outdoor cabinets are connected with copper tube by which cold air moves to the house efficiently. 

  1. HVAC packaged unit

The HVAC packaged unit is an all-in-one unit with no crawlspace or basement. All parts of the system are held in a cabinet. The evaporator coil, condenser and Compressor are all housed together to save space.

The cabinet is placed on the ceiling, cement slub or outside the home. Despite being an outdoor cabinet, the primary function of a packaged unit is indoor.

The Condenser Coil Of Central Air Conditioners: Inside Or Outside? 

The condenser coil is mainly outside. The air conditioner’s condenser coil is a large, square unit placed outside the home. It is mainly a part of a spilled air conditioning system or heat pump.

It works along with the Compressor by converting refrigerant gas back to liquid. It is mainly the opposite of the evaporator unit. It sends heat carriers by the refrigerant to the outside. 

So, We can say that the condenser coil of central air conditioners is an external component.

Can Condenser Coil Get Dirty? Signs Of The Dirty Condenser Coil

Condenser coil can get dirty quickly. As we have already known, a condenser coil’s primary function is to condense the refrigerant vapor to liquid. The condenser coil gets dirty while cooling the refrigerant.

Dirt from the outside air is absorbed into the outdoor cooling unit and begins to build up in the coils of central air conditioners.

If the condenser becomes dirty or fouled, it fails to condense the refrigerant.

Signs Of The Dirty Condenser Coil

What happens when your central air conditioner has a dirty condenser coil? Does it work properly? Let’s see! 

  1. Your home won’t cool properly.

If your air conditioner doesn’t work correctly and your home isn’t staying cool like before, you may blame the dirty condenser coil. Why? 

When dirt builds up your condenser coil, it produces a layer on the condenser coil. The layer acts as a barrier, making air and heat transfer harder. Thus air conditioners do not work correctly.

  1. A high energy bill.

As dirty condenser coil makes it harder and longer to cool your home, it needs more energy. So it will raise your energy bill.

  1. System breakdown.

The air conditioning system may break down at any time because of the dirt. Air conditioners have to work harder to cool down the place, and for other components’ being hot, the system may stop any time.

Five Easy Steps To Clean The Condenser Coil

There is nothing worse than having your air conditioner’s condenser coil dirty. It creates many problems and your AC may stop working. You have to make sure your condenser coil is free from dust, dirt, and debris to prevent the problem.

So, here are five easy steps to clean your dirty condenser coil. 

But before moving into steps, let’s learn about the required tools. 

Required Tools

  1. Screwdriver/ socket
  2. Cordless drill
  3. Hose or spray nozzle 
  4. Soft-bristle brush 

Step-By-Step Of Condenser Coil

Step 1: Disconnect the power

Disconnection of the service of AC is the first step. Pull the plug connector in the power box, or flip the AC breaker switch off at the main breaker level. Disconnection of power is fundamental. Otherwise, you may be injured during cleaning.

Step 2: Remove the screws

After disconnecting the power, you have to remove the screws with the help of a cordless drill.

Step 3: Panel removal 

Starting from the backside of the unit, remove the panels one-by-one. It would be best to be careful while removing the panel so that it doesn’t damage.

Step 4: Cleaning the fins

Use a soft-bristle brush or a hose with a spray nozzle to clean the fins. It would be best if you brushed up and down. Never brush side to side. You can spray water from the top. Do not spray straight on the fins. It can cause damage to the fins. 

Step 5: Reinstall panel

Reinstall the panels in the reverse order you removed them. Use a screwdriver. Leave the screws loose until all the panels are in, then tighten the screws. 

So, hopefully, following five easy steps, you can easily clean your condenser coil of the central air conditioner.
