How much should it cost to replace the evaporator coil

Evaporators are used in Air Conditioning systems. An evaporator is a device in a process used to turn the liquid form of a chemical substance like water or into its gaseous form or vapour. It works in the exact opposite way of a condenser; it turns the liquid refrigerant into gas thus lowering the heat content and making the flowing fan air much cooler in the process.

Evaporator Coil

There are two different kinds of general evaporators available, both requiring evaporator coils

  • Flooded evaporators
  • Dry or Direct expansion evaporators

Functions Of Evaporator Coil

Evaporator coils are the most important part of an HVAC system’s evaporator. These coils are part of an air conditioner or a heat pump that absorbs the heat from the air in your house. An evaporator coil is responsible for picking up heat from the indoor air and transfers it effectively.

As we know that the job of the air conditioner is not to cool the air, rather to simply move the heated air from here to there. That is where the function of the coil comes in, to add it to the refrigerant. After coming out from the evaporator coil, the refrigerant flows through an insulated conduit to the outer AC unit, located outside or behind the house. Thus begins the job of the condenser coil.


Location of evaporator coil

The evaporator coil is located inside the air handler or the blower compartment, where it holds the entire chilled refrigerant and then the condenser moves into it. As the air from the blower coil moves over the coil, the cold refrigerant removes the heat, from your home’s air. Thus the refrigerant becomes warmer and travels to the condenser coil outdoors.

How long does an evaporator coil last?

Evaporator coils require proper maintenance, for consumers to use it to its full potential. If maintained properly, then it should last for 10 to 15 years depending on the usage, which is the ideal life of an evaporator coil and also comparable to the average lifespan of an air conditioning unit.

However, misuse and improper maintenance of the Ac unit can cut its lifetime shorter. If it isn’t being regularly cleaned then dust, dirt, insects, pollen grains, and such can move past the air filter and collect over the evaporator coil in due time. This will reduce the AC unit’s efficiency and lead to leakages and corrosion.

When does an evaporator coil go bad?

In 10 to 15 years the condition of the evaporator coil begins to deteriorate. As time goes on the coil’s inner lining starts to wear off due to erosion which leads to weakening of the metal. The outer lining also experiences the same corrosion, leading to damages and refrigerant leakages.

A few tell-tale signs of an evaporator coil going bad are listed

  • There is leakage from your air conditioning unit.
  • Weird sounds are coming from your AC units such as; banging, clanking, or hissing noises.
  • The air conditioner stops working altogether, switching off completely.
  • Your AC unit keeps turning on or off at random times.
  • Warm air starts blowing through your air vents.
  • Your HVAC unit has difficulty in cooling even after switching it on for long durations.

Cost of replacing an Evaporator coil

If a thorough cleaning cannot save the evaporator coil, then replacing it would be a good option. On average for replacing a coil for a home air conditioner, the prices range from Rs 400 to Rs 2500 depending on the type and manufacturer of the coil.

These prices do not include labour costs. These copper coils are available at a lot of places, including online shopping websites. It is a cost-effective method to fix your AC unit instead of purchasing a whole new Air conditioner.

Benefits of replacing the evaporator coil

  • Replacing the evaporator coils is very cost-effective, better than getting it repaired, thus saving a lot of money.
  • If your air conditioner is under warranty during the time of replacement, getting a discount is very easy.
  • For old HVAC units, the replacement of these coils can add a lot to the overall lifetime of the system.

What is a heat exchanger in a furnace?

The heat exchanger is an essential part of the furnace as it is responsible for heating the air. Heating indoor air isn’t possible without having a heat exchanger in a furnace. A heat exchanger is a device responsible for transferring heat between two or more fluids. The furnace combusts fuel in a chamber to produce heat. This process of combustion generates heat energy from the fuel source to heat air.

Heat exchanger In A Furnace

The combustion fumes and gas mixture is harmful to humans and is not safe for breathing. As this harmful gas not used for heating air, a heat exchanger needed to heat indoor air. A heat exchanger used to transfers heat without transferring the fluid. The furnace heat exchanger contains tubes to transfer air and exchange heat through it.

Furnace made up of various components and the heat exchanger one of the important parts of it. It takes the most of the furnace. It helps to keep you safe from combustion byproducts.

If any issue occurs it would affect the furnace and can create various problems. The heat exchange chamber should sealed properly to avoid the mixing of harmful gases with fresh air. The owner should know the furnace heat exchanger as it is an important part of the heating system.

What is a furnace heat exchanger?

The furnace heat exchanger is a system that is responsible for heating air indoor.  It works to separate combustion byproducts from your breathing air. The furnace heat exchanger comprises tubes and coils. It combusts the fuel and produces the heat. A furnace heat exchanger is a kind of metal shield present between the combustion chamber and blower.

The combustion chamber heats the exchanger, the air gets blown through it and the safe air heated. This breathable air then circulated indoors. As a mixture of combustion gas and fumes fatal, a heat exchanger required for fresh breathable air. Heat exchanger circulates the fresh heated air from the furnace through air ducts to the indoors.


The heat exchanger of a furnace starts from the burner assembly and connects the vent pipe to exchange the heat. The Tube network and the metal chamber together help in the exchange of fresh breathable air. One should always ensure that the heat exchange chamber properly sealed. If the heat exchanger not sealed properly, it could lead to the mixing of fatal gasses with fresh air.

How does a furnace heat exchanger work?

A furnace heat exchanger works to transfer heat from the combustion chamber to its exterior part. The heated air is blown via the ductwork throughout the indoor. The heat exchanger has various types of components in it and also various materials needed in construction.

Heat exchanger dispenses heated air from the furnace to the indoor space. When the combustion chamber heats the exchanger with gases, the air gets blown on the other side. The blown air heats the fresh air and it is then circulated to the indoor space.

The furnace heat exchanger works to interact with high-temperature gas with low-temperature gas. This process helps to ensure the exchange of heat. There were different types of components used in the furnace heat exchanger to transfer fresh heated air. Spiral tubes, fins, shells, tubes, and adiabatic wheels widely used components in the heat exchanger.

How to detect furnace heat exchanger problem

It is important to keep a check on the furnace heat exchanger frequently to avoid problems. There are flue gasses present on the furnace which are harmful, so it is necessary to inspect the furnace. Also, to ensure that the furnace heat exchanger is working efficiently, one should not ignore any signs.

A cracked furnace heat exchanger can lead to exposure to toxic gases. Carbon monoxide, nitrous oxide, and sulfur dioxide can be released when a furnace gets cracked.

What causes an evaporator coil to freeze And How To Fix It

An air conditioner works due to the circulation of refrigerant inside its two coils or pipes made of copper. The refrigerant a liquid substance that gets converted into the form of gas after being processed in the evaporator and its coils. As its state keeps changing, it is capable of absorbing heat. The refrigerant gas travels to the condenser coil and gets converted to liquid again and releases heat. By this process, heat pumps and air conditioners produce cool air.

Evaporator Coil Uses

The evaporator coil is part of the internal components in a standard central air conditioning system. Whereas in heat pumps. The evaporator can be anywhere in the inside or outside units, which depends entirely on whether the machine is providing cooling or heating to your home or workplace. In a heat pump, the outdoor coils function as evaporators for the generation of heat.

What causes an Evaporator Coil to Freeze?

Evaporator coils can freeze due to several reasons, they can be-

  • Defrost cycle malfunctioning-

Defrost cycles a part of cooling systems as they prevent the evaporator coils from getting accumulated with ice and frost. The most common principle of this cycle is to reverse the flow of refrigerant temporarily and allowing the flow of hot refrigerant through the coil, which will melt the ice that has been built upon the coils. If this defrosts cycle of your air conditioner is malfunctioning, it will be unable to melt the ice and frost that is accumulated.

  • Cold Coils-

If the temperature of your air conditioners evaporator coil goes down below 32 degrees, then this can lead to the freezing of the water vapors around the coil. Initially, there will be only a buildup of a thin layer of frost and ice, but overtime it will become a large layer that will be difficult to remove.

  • Decreased level of refrigerant-

The refrigerant is responsible for the absorption of heat in the air conditioning system. The content of refrigerant can get decreased due to problems such a leakage etc. This decrease leads to the incapability of the system to absorb heat which leads to more cool air passing all over the coils.

What to do to fix a Frozen Evaporator Coil

The evaporators can stop working or their effectiveness to produce cooling can get decreased due to the buildup of frost and ice all around its coil. Since they enclosed in a unit and not in contact with the outer surrounding. They can’t even absorb heat from there, and the air that ejected out from the supply vent will be hot. Due to this reason, the cooling mechanism of the system can get affected. When this happens, it’s best recommended calling a local HVAC professional. And your technician will mostly-

  • First, turn off the air conditioner’s power so that it stops operating- to be safe.
  • He will then open the evaporator coil’s access door to check the buildup of frost and ice.
  • If the coils were frozen, then your technician can get rid of it using a various number of ways. But it is important to note that hammering or using tools to chip off the ice should never be done as it can damage the coils seriously.
  • The technician makes sure that the defrosted coils properly cleaned and in nice condition. You can use soft-bristle brushes to clean coils. Usually, the directions were given by the manufacturer on how to clean coils to prevent damage. Specifically to the fins as the fins provide extra surface area to produce heat.
  • In case the heat transferring fins appear bent, using a specialized tool called a ‘fin comb’ they were straightened. And all these tasks are best left to the HVAC Professional.

After the technician is done following the above steps, and the coil is clean and the ice melted, your air conditioner should be good to go. Turn the air conditioner on to check. Don’t forget to take instructions, tips, and tricks to prevent your evaporator coil from freezing again.


The article above has covered important points such as what are evaporators and why do we need one, how does evaporator coils get frozen, and how to solve this problem.

  • ●      However not all blank screen problems are technical, it caused by a software issue, so if these methods don’t work calling the Trane dealer for expert help is advisable.

What is the difference between a Fireplace Insert and a Built-in Fireplace?

When people talk about fireplaces, they usually refer to an open fireplace. Basically, in other words, means an open area in the wall with a flue on top of it to have a fire indoors at home or workplace. The basic idea behind fireplaces is that it’s open.


Some fireplaces have glass doors in them, and you might feel that as it is not open anymore, but still it’s a fireplace.

Types of Fireplaces

Fireplaces were of two kinds- Factory-Built Fireplaces which also known as prefabricated fireplaces or prefabs, and Masonry Fireplaces.

Masonry Fireplace

This fireplace almost all the time made up of bricks. Some specialty types of masonry fireplaces that are more exotic in nature, which also 99.9% made up of brick, use some refractory materials.

Factory-Built Fireplace

A factory-built fireplace nothing but a fireplace which made up of metal boxes containing refractory bricks inside them. They manufactured in such a way that they framed in houses without needing masonries. Sometimes gas used to fuel them but most of the time, woods used for burning. These fireplaces are considered absolutely safe if installed by the manufacturer’s instructions.

The Heatalator

A heatalator is more of an in-between situation. This name given to brands and their products which are generally like them. For example, just as all tissue papers are not only of one brand, you can prefer to ask for that particular one brand and you will be shown plenty of different options like that.

This same thing applies to the heatalator. Heatalator like a combination of both the above-mentioned fireplaces made up of a metal firebox and built to fit into a masonry structure. Although it was built in a factory it still considered a masonry fireplace because of its heat transfer requirement, clearance, etc.  in a nutshell, a heatalator also a fireplace.

What does a Fireplace Insert mean?

Now comes the question, what is a fireplace insert? In a simple word, it is like a ‘stove’. Gas or wood anything can be used to fuel it, it is basically nothing but a stove which can be inserted or fit into an open fireplace.

Most of the time, fireplaces exclusively installed into masonry fireplaces. But some special models come into the category installed into prefabricated fireplaces.

While installing a fireplace insert, it mandatory to follow all the instructions given by the manufacturer, or else you will put your house and family members, and yourself at risk. Follow the below-given two-piece of advice which can help you keep your family warm and safe in the long run-

  1. Make sure that your stove has a perfectly sized linear from the chimney to all the way down to the top of the stove.
  2. Make sure that any insert buying capable of being installed to your fireplace.


This article has covered what fireplaces and inserts are and their types and their difference. In a nutshell, the basic difference is that a fireplace insert is equipment that is to install into an already existing wood-burning or gas burning fireplace to increase its efficiency. Whereas a built-in fireplace is a brand new installation in a home where there is no already existing fireplace. So basically, an insert supposed to install into a fireplace that you already have.


How to Identify a Cracked Furnace Heat Exchanger

A heat exchanger is a system containing tubes and coils in a furnace. Its work is to heat the air. A furnace works to combusts the fuel by which heat generates in it. The heat exchanger is a type of metal shield present between the combustion chamber and the blower.

Heat Exchanger

It circulates the heated air from the furnace via air ducts in your indoor space. A heat exchanger needed for breathable air, as a mixture of combustion and fumes is not safe.
