Today, instead of walking into the Arctic Circle, it seemed like you were in the Arizona desert. The possibility exists that your evaporator coil needs to be replaced. According to the model and manufacturer, evaporator coil replacement costs might range from $600 to $2,000 or more.

When Do You Need To Replace Central AC Coils?

The average lifespan of a central air conditioner is ten to fifteen years. The likelihood of a system breakdown increases with the age of your computer.

For years, the evaporator and condenser coils have been under pressure because to the constant expansion and contraction of the coils. Because of this, they are a frequent source of AC component failure.

AC Evaporator Coil Life Expectancy

A good evaporator coil is going to endure a long time if it’s well-maintained. The warranties for high-end equipment are often longer and more generous.

Only after 15 to 20 years will even the greatest coils begin to have an impact on the efficiency of your system.

Condenser Coil Life Expectancy

The lifespan of a condenser coil is anywhere from ten to twenty years. How long your condenser coil will survive, however, is also determined by how well you take care of it.

How Much Does an Evaporator Coil Replacement Cost by Unit?

The size of air conditioners varies from house to house. In contrast to your neighbor, who may have a 3-ton unit outdoors, you may only have a window unit. As a result, the cost of a new evaporator coil might range from $600 to $2,000, depending on the type of unit.

Replacing an evaporator coil costs, on average, about:

  • $550 per ton for 2 tons
  • a 2.5-ton haul costs $675.
  • 825 dollars for a three-ton haul.
  • $925 for 3.5 tons
  • 1,000 dollars for a four-ton haul.
  • $1,075 per ton

This price only covers the cost of the replacement unit, not the associated labor costs. The average cost of labor is $700. Consult your local air conditioning repair firm if the size of your system isn’t clearly stated on the unit.

Evaporator Coil Replacement Cost Breakdown

Besides the size of the unit, the evaporator coil brand and labor costs should also be taken into account. As a precaution, you should also be prepared in the event that the AC repair firm recommends additional repairs.


According to the job and service area, labor charges can range from $400 to $1,000. Because you require a license to handle refrigerant, labor costs are about the same as the evaporator coil. You don’t want to come into contact with refrigerant on your skin.

Ease of Access

It matters a great deal where your air conditioner is located in relation to the rest of your house. As a rule of thumb, the unit is a convenient location for a repair. The AC repair technician will have to shimmy into a tight space and may have to disassemble more of the unit if the device is older or difficult to work in.

When Should You Schedule A Service Call For Your AC Unit?

After six months without a tune-up, it’s time to get in touch with an HVAC professional.. In addition to checking coolant levels, blower and condensate drain lines, thermostat, outdoor unit and inside coils while they’re there, they can also perform other maintenance tasks.

Air conditioning units need regular maintenance, and a specialist will inform you what that upkeep is. When you make an appointment with an HVAC technician, the AC technician will:

  • Check the voltage, airflow, and temperature of the system.
  • Replace the air filters and, if necessary, clean the coils of any accumulation.
  • Perform a heat pump test.
  • Temperature readings should be checked.
  • R-22 refrigerants should be disposed of carefully after they have been repaired of any leaks.
  • To ensure everything is working properly, go through your system from top to bottom.
  • The coils should be free of any residue.
  • Repair or replace any damaged or worn out components.
  • System grade and anticipated lifespan are provided.

When you have an AC service firm maintain your unit, they will tell you if your older HVAC system needs a new coil. They may also offer you an estimate of how much it will cost to install a new air conditioning system.

How Can You Extend The Life Of Your New Coil?

If you want your coils to last as long as possible, you need to take care of them. It will, however, have an effect on your monthly electric expenditures.

With a little bit of knowledge in DIY home repair and a few basic tools, you can easily care for your coils. What you need to do is as follows.

In addition to keeping the air in your home clean, air filters also help to keep dust and other impurities out of your air conditioner. Your air conditioner’s lifespan would be shortened if it didn’t have an air filter.

Changing your HVAC system’s filters is the single most important thing you can do to keep it working efficiently. Every 30 to 60 days should suffice for the vast majority of households.

If you have pets, if you smoke, or if there are a lot of people living in your home, you may need to change them more frequently.

Maintaining your heating and cooling system is essential. Everything depends on every other part. The condenser, compressor, blower, and other components can be put under stress if the evaporator coil is not performing properly.

As a result, low refrigerant levels can damage the system, resulting in overheating, which can harm the delicate coil fins and connections.

Coil Cleaning – It is critical that the indoor and outdoor air conditioner coils are kept clean and that appropriate airflow is provided to them. The accumulation of leaves and other debris on the condenser’s exterior is a cause for worry because it restricts airflow.

The evaporator coil in your home will quickly become clogged with dust and other airborne particles if your filter is dirty or missing. Because of this, if you frequently fail to change your filters, you may need to inspect your evaporator coil.

Additionally, minor repairs might assist to keep your coils in good condition and increase their lifespan.

Best AC Coil Cleaner Buying Guide

Every year, households across the United States turn on their air conditioners to prepare for the upcoming summer months. While there are many different types of cooling systems, they all need to be well-maintained if you want to be cool and comfortable all year round.

The coils are the most important portion of your system to maintain clean, but there are several others. Coil cleaners come in a variety of shapes and sizes, and we’ll go through the pros and cons of each so you don’t have to.

AC Coils Explained

Most homeowners find HVAC and air conditioning systems to be confusing, which makes routine maintenance difficult. Every time you need to hire a professional, it might cost a lot of money. In order to properly clean the AC coils, you must know where they are and what they actually do.

When you run your air conditioner, it uses refrigerant, which is converted from gas to liquid form by components inside your machine. When working with the condenser coil, the compressor is responsible for converting refrigerant from a gas to a liquid. The liquid then passes through an evaporator coil, which does exactly what its name suggests: it evaporates the liquid.

During the process of cooling the coil, the liquid evaporates. In order to keep your house cool, a fan blows cold air across the coil, but the hot gas being evaporated is returning to the compressor. When the refrigerant returns to a liquid condition, the heat is dissipated outside, and the cycle repeats.

That’s only a rudimentary explanation of the process, but those coils are critical and must be kept clean for a variety of reasons.

The Importance of Keeping your Coils Clean

Depending on a variety of variables, the coils inside an air conditioning machine can become soiled over time or fast. You have to be on the lookout for dust and other particles going inside the system, as well as on the outside. There are a lot of things that can get stuck to the outside of a cooling system, including grass, leaves, and other debris. That’s a bad idea when you’re trying to cool down your system.

Your system’s components can overheat if ventilation is obstructed or impeded, resulting in malfunctions. However, this only applies to the surface of your air conditioner, as the inner coil can also cause issues if it isn’t properly cared for.

The inner and outer coils are important parts to pay attention to because of potential problems including frozen coils, leaks, and bad odors. You’ll save money on your utility costs and have a well-functioning system if you maintain the coils clean. Fortunately, the best AC coil cleaner can help, but you’ll first want to inspect the coils on your system to determine if they’re clogged or accessible.

Perform a Visual Inspection

Walking outside is the first step to inspecting the coils. In most circumstances, the condenser coil may be found on the outside of a cooling system through slots, and it’s straightforward to access in most cases. Unfortunately, it is the most susceptible to harm.

Check for any small sticks or other debris from yard maintenance or Mother Nature if it’s close to the ground. A system can easily become clogged with debris such as plastic pieces and grass clippings, which are widespread in the environment. Even while cleaning the condenser coil is straightforward in certain systems, you’ll still require a few tools and condenser coil cleaner. You might not even have to remove it if it’s a window-based system.

When it comes to the evaporator coil, dirt and dust, as well as grime buildup, are the most common issues. Unfortunately, the type of system it is can make it difficult to access to. If you’re dealing with a split-level system, you’ll usually have to remove an access panel or go into an attic or crawl space to see the coils.

You may discover other issues with your system while inspecting the condenser and evaporator coils. You may need to call in a professional if that is the case or if you are unable to access your coils.

DIY or Hire a Pro

Consider hiring a professional if you’ve done a visual inspection and don’t want to bother with accessing the inner coils. Depending on where you live, the type of system you have in your home, and your budget, this might be a difficult chore..

The expense of cleaning your own coils should be factored in before hiring a professional. Coil cleaner is the only special tool you’ll need; the rest are common household items. You should anticipate to spend anywhere from $30 to $100 to clean both coils using cleaner and any necessary instruments.

However, if you have problems removing a panel or otherwise encounter difficulties, you will be forced to seek the assistance of a professional. The same is true for coils that are too filthy to be cleaned using conventional procedures and require a thorough cleaning instead. If such is the case, the best option is to use an HVAC system expert, but finding the appropriate individual might be difficult.

No official title for coil cleaners may be found on the internet or through famous handyman services. It’s a service that may be offered by some HVAC businesses, but if it’s merely a light-duty cleaning and nothing else is wrong with your system, you can hire a trustworthy individual to do the job.

You’ll need to check references and receive multiple quotes before hiring a coil-cleaning service. Despite the fact that you may receive the cheapest or best person initially, in most cases, it pays to seek multiple quotes. Many people who undertake this kind of work may charge for an estimate, but if you hire an HVAC company, you’ll also have to pay for a service call.

Costs range from $50 to $150 for a coil cleaning performed by a professional or a person. Again, prices may vary depending on your region and the availability of professionals in your area who can clean your air conditioner’s coils.

Tools of the Trade

Coils can be cleaned with only a screwdriver and a few other common household items. Though you can remove the covers by hand, you can save a lot of time by using a screwdriver bit. If you don’t have a corded or cordless drill, you may have a hard time getting to the evaporator coil.

As long as you don’t already own a screwdriver or a drill, there are a plethora of possibilities to pick from. To make things easier, we recommend purchasing a screwdriver bit set, which has a variety of different sizes and shapes of bits. There are several alternatives, but if you’re just going to be working with screws, we recommend this DeWalt 45-piece bit set.

You’re halfway there once you have a tool that lets you get to the coils. Coil brushes and fin combs may be all that’s needed to complete a quick cleaning, but you may want to check out our buying guide first to see if you need them. Any bent fins on your system will eventually need to be straightened with one of these handy little tools.

If you plan to clean your coils yourself every year, the only other gear you’ll need is a coil gun sprayer. Due to its design and quick-connect method, it may not be ideal for all sorts of cleaners, but it will speed things up nonetheless. Depending on the layout of your system, you may also need a ladder, gloves, and a water hose.

How to Clean A/C Coils

For the condenser and evaporator coils, we’re now going to talk about the actual cleaning process. You should keep in mind that these are simply basic measures and may change slightly based on your home’s heating and air conditioning system.

How to Clean Condenser Coils

Be sure to turn off your equipment before starting any work. Make sure the electricity is turned off before you begin cleaning your air conditioner’s evaporator coils.

You should be able to see any debris on the condenser coil that could harm your unit. Weeds, bushes, and tall grass are all included in this category. A coil brush can be used to remove debris from the system. Using a paintbrush or anything that could damage the coils is tempting, but a decent coil brush is not expensive.

It’s a good idea to check the fins for damage after the debris has been removed. Remove any remaining debris from the outside of your fins with a fin comb. When you’re finished and satisfied with your job, go ahead and get your coil cleaner. Just follow the manufacturer’s instructions for the product you’ve purchased, and you’ll be good to go.

The condenser coils should be inspected for damage or bent fins once they have been cleaned and dried. Your system should be ready to go if everything is in order. In some cases, you may still require a professional to remove the fan or other components from your system. Consider hiring a professional cleaner if your cleaning efforts were ineffective.

How to Clean Evaporator Coils

Things can get ugly with the evaporator coil, especially if it hasn’t been cleaned before. Before you begin, be sure to turn off the electricity to your unit and get some evaporator coil cleaning, both of which we’ll cover in the instruction that follows.

Evaporator coils can be tricky to clean because of their tight spaces and the risk of damaging the fins if you get too close while doing so. It will take longer to clean the evaporator coil, and you must be careful around the drain line and drip pan. Wear safety goggles and put aside some time.

It is feasible to clean the evaporator coil yourself, but because of where it is, hiring an HVAC professional or someone with coil cleaning skills may be more convenient. If you plan to clean the evaporator coil yourself, this video will give you a clearer understanding of what to expect.

How to find the Best AC Coil Cleaner

A thorough understanding of the process of cleaning your own coils can be gained through this guide. Coil cleanser is the one thing we haven’t talked about before, and it’s essential for cleaning coils. A speciality product like this one doesn’t have as many options to choose from as compared to other cleaners.

As a result, finding a solution that is both safe and simple to use is the primary concern. Despite the fact that most coil cleaners have more in common than they have differences, there are a few factors you should keep in mind before making a final decision.

What type of coils do you have?

There are times when it’s more convenient to call in a professional. In today’s HVAC systems, there are two types of coils used, and cleaners for each kind. Coils made of microchannels are more durable, compact, and efficient than those made of ordinary fins.

They can be located on the condenser and the evaporator, respectively. These coils can be cleaned more easily with the use of special cleaning formulations. In addition to using conventional coil cleaning, it will be helpful to know what type of coils your system has.

Types of Coil Cleaner

In the world of air conditioner coil cleaners, there are two main categories: aerosol spray cans and 1-gallon jug cleansers. Foaming cleaners and no-rinse cleaners are both available, but they all come in a jug or aerosol can.

Some products are marketed for use on evaporator coils, while others are marketed for use on condenser coils. At least half of those items may be used on either metal or plastic, and several cleansers can be used to a wide range of other materials as well. Appliances in your kitchen and car are included in this.

Safety Concerns

It’s always a good idea to use cleaning products with caution, as you could injure yourself or the items around the item you plan to clean. There are several cleansers on the market today that claim to be biodegradable, compared to only a few years ago, which is a big improvement.

Look for USDA-certified materials for cleaning coils in a kitchen or any other place where food is cooked. Most firms make this information readily available, but if you can’t find it, check the back of the can. Coil cleaners are a common product category, and several firms have a range of USDA-certified coil cleaners.

Capacity vs. Cost

Everyone enjoys a good price! When it comes to money, it doesn’t matter whether you live in the United States or New Zealand. When it comes to cleaning items like cleansers, that is typically linked to capacity, and that is the situation with HVAC coil cleaners.

This may seem like an excellent deal, given the long shelf life of cleaners, but it’s actually a bad idea. I mean, how often are you going to clean your coils in the first place? If this is your first time making a purchase, it’s best to go with a smaller amount than you could otherwise regret.

A lesser capacity allows you to test a product before deciding whether or not to purchase it. Unless your coils are exceptionally clean to begin with, this is the best option if you’re not sure exactly what you’re searching for. However, it will cost you more in the long run.

The average aerosol can weighs between 16 and 18 ounces, based on our experience with the product. A double-pack of cans may save you money over purchasing individual cans. It is possible to use a spray cleaning on both the evaporator and condenser, but it is most commonly applied to the former.

There are a lot more possibilities if you prefer gallons to aerosol cans. Most are offered in 1-gallon jugs, with the exception of a few companies who provide 5-gallon pails. In most circumstances, the initial cost will be higher for something that will only be used for a short period of time.

The Best AC Coil Cleaners

There are a number of similarities among the many HVAC coil cleaners on the market. While the label, color, and name may be distinctive, the contents of each bottle are strikingly similar. In light of this, we’ve compiled a list of the top condenser and evaporator coil cleaners.
