Where is the evaporator core located?
An air conditioner's evaporator coil, also called the evaporator core, is the part of the system where the refrigerant absorbs heat. It's where the cold air comes from. The evaporator coil is inside or near the air handler where the blower fan is.
Is the evaporator coil inside or outside?
An evaporator coil is the part of an air conditioner or heat pump that absorbs the heat from the air in your house. It is located inside the air handler or attached to the furnace.
How do you clean an evaporator coil without removing it?
Use a compressed air canister. One of the best ways to get the dirt and other debris out is to use compressed air. Blow the air into the coil to loosen the dirt. If there's stubborn dirt, though, you might need to put the nozzle close to the bottom of the debris, along its side.

How do you unblock an AC coil?
You'll need a wet-dry vacuum, a bucket to catch all the gunk your vacuum might dispel, as well as some white vinegar, or chlorine bleach, or hydrogen peroxide. Start by turning off your AC unit at both the thermostat and the breaker. Water + electricity + you is rarely a good combination and safety is always important!
What is the difference between condenser coil and evaporator coil?
Evaporator Coils vs. Condenser Coils. The evaporator coil is the part of an air-conditioning system that removes heat and moisture from indoor air to cool it. The condenser coil takes that heat and releases it outside.
How often should evaporator coils be cleaned?
every three monthsAt times, evaporator coils can collect debris and dirt quickly, so monthly cleaning may be needed. Typically, however, evaporator coils need to be cleaned every three months. Without proper care and upkeep, you can end up spending money on air conditioner repair as opposed to maintenance.

Signs of a Leaking Evaporator CoilWater Overflowing Drip Pan. Your AC unit has a drip pan to collect normal condensation build-up. ... AC Takes a Long Time to Cool Home. ... Weak, Unresponsive Airflow. ... Warm Airflow.
Where is the condenser coil located?
You'll find your condenser coil within a large, square box with a big fan on top located next to your house. Since the condenser coil's job is to release the heat from inside your house, it makes sense that the heat would be released into the outside air.
How does an evaporator coil work?
The evaporator coil works when air flows over a series of thin metal fins that are cooled by the refrigerant within the copper tubing. Technically, the evaporator moves the heat from the air into the refrigerant and the cooled air is then blown into the home through the ductwork.
How much does it cost to replace an evaporator coil?
Replacing your evaporator coil isn't cheap. On average, it'll cost about $1,000, but depending on the size and make of your system, it could be as low as $600 or as high as $2,000.
What to do if your evaporator is leaking?
If you find that your evaporator has started leaking, you basically have three options: Use a Sealant - One option is to inject a sealant into the refrigerant which travels through the system in search of leaks.
What is the coil of an evaporator made of?
The evaporator is where the cold air actually comes from and the coils are made from metals that easily conduct heat. Frequently the coils are made from copper, but steel and aluminum is also used. The tubes are bent into "U" shapes and are stacked into a panel. There are several steps that take place to cool the air.
How does a compressor work?
The compressor keeps the process running by pulling the cold, low pressured refrigerant through the evaporator coils and transfering it to the condenser in a hot, high pressured condition.
Why is air blown over a condenser?
Air is blown over the condenser by a large fan to assist the refrigerant in releasing it's heat. Within the condenser are many copper coil tubes that wind around the housing. This gives the refrigerant plenty of time to release the heat which was moved from within your home.
Where is the evaporator coil located in a split system air conditioner?
What is an Evaporator Coil and How Does It Work? In a split-system air conditioner, your evaporator coil is located inside, away from the condenser.
What is an evaporator coil?
The evaporator coil is made of metals like copper or steel because they conduct heat well. Outside the coil are fins, which protect the coils and allow the air to pass through to the coils.
Why is cooling misnomer?
The process of cooling is somewhat of a misnomer, because air is not cooled so much as the heat is removed. Refrigerant is sent to the evaporator coils inside the home to remove heat and humidity from the indoor air.
Do evaporator coils need to be repaired?
Evaporator Coil Repairs. Your air conditioner’s evaporator coils also need repairs on occasion, particularly related to maintenance. Without regular maintenance, the coils may become too dirty. If you wait too long, they may accumulate condensation and freeze from the refrigerant.
So, what is an evaporator coil, exactly?
An evaporator coil is the component of your heat pump or air conditioner that absorbs the heat and moisture from the air inside your house. It works alongside the condenser coil to produce cool air and complete the heat exchange cycle.
How does it work?
To understand how an AC evaporator coil works, it’s important to understand how an air conditioning unit functions as a whole. Unlike how a furnace produces heat, an air conditioner doesn’t actually produce cold air.
Where is it located?
The evaporator coil is attached to your furnace or inside your air handler, depending on the system. The AC evaporator coil is located inside the portion of the air conditioning unit that sits inside your home and should only be accessed by a trained HVAC professional.
How do these two work together?
Evaporator coils and condenser coils work in tandem to produce cold air and complete the heat exchange cycle. They form one continuous loop, where the evaporator coils absorb heat and the condenser coils release heat. The cooling process could not be completed without both sets of coils.
More on AC condenser coils
The condenser coils are located inside your unit’s condenser, which is the portion of the air conditioning unit outside your home. The condenser is responsible for turning refrigerant into a hot, highly pressurized gas. This gas then flows through the condenser coils, which are all in the path of blowing air, so the heat from your home is released.

Why does my evaporator tray have a lot of moisture?
If the tray has a lot of moisture, it could be due to a blockage in the drain line that connects the weep hole to the tray. If that's the case, you can open up the drain line by pushing a wire through it. Once the cleaning has been done, push the evaporator back into place if you've moved it and screw in the access plate.
How to clean condensation from evaporator?
