An aircon cooling coil is essentially the heart of your air conditioner, where the magic happens. It's where the cold air comes from.

The evaporator coil is typically made from copper, steel, or aluminum because these metals conduct heat easily. Most residential AC evaporators consist of tubes bent into U-shapes and set into panels.

The panels are usually positioned in the form of an "A" and are lined with thin pieces of metal known as fins, which bring the passing air to be cooled closer to the coils to maximize the refrigerant's effect.

As the AC runs, the compressor pulls cold, low-pressure liquid refrigerant through the tubing in the evaporator coil. The refrigerant passes through the expansion valve, which relieves pressure from the liquid refrigerant, rapidly cooling it.

The liquid refrigerant leaving the expansion valve is quite cold, allowing it to absorb heat from the air. The expansion valve also controls how much refrigerant flows to the evaporator.

The blower fan draws hot room air over the evaporator coil, and the refrigerant absorbs heat from the passing air, warming up and evaporating in the process.

Even a fine layer of dust on the evaporator coil can reduce its efficiency by acting as an insulator, keeping the heat in and the air away from the cold coils. This means the coil can't absorb as much heat as it can when clean.

Higher energy use is another issue that may occur due to a dirty evaporator coil. The system will have to run longer to provide the indoor temperature you want, resulting in increased energy consumption.

A layer of frost on your evaporator is never normal and can cause the compressor to fail if left unchecked. Letting your system run with a frozen evaporator raises the temperature in the compressor and can eventually lead to its failure.

Tiny pinhole leaks can also develop on the evaporator coil due to corrosion from the mixing of moisture with chemicals found in household air. Oily residue around the evaporator or in the drain pan is a sign your coil is leaky and needs replacement.

Here are some common causes of evaporator coil damage:

Ensuring good home ventilation can help reduce the risk of evaporator coil damage by minimizing the presence of volatile organic compounds (VOCs) in your indoor air.

Dirty coils can force your air conditioner to work harder, leading to frozen coils. Regular maintenance, including professional tune-ups, can prevent issues like cracking, freezing, and dirt buildup.

Airflow issues can cause blocked vents, faulty filters, or defective ductwork, resulting in frozen coils. Cleaning the unit, replacing filters, and ensuring all vents are open can help resolve this problem.

Refrigerant leaks can cause poor cooling and higher energy consumption. Leaks reduce refrigerant, leading to ice on the coils, so it's essential to call a technician to inspect and fix the issue.

Dirty and debris buildup on condenser coils can easily occur, reducing efficiency. Cleaning the coils regularly or scheduling a professional cleaning can help prevent this.

Cracking, freezing, and dirt buildup on evaporator coils can be prevented with regular maintenance, including professional tune-ups. Homeowners should replace air filters, but professionals should handle more serious problems like frozen or leaky coils.

Your aircon cooling system relies on two key coils to keep your home cool. The evaporator coil is located in the indoor air handler.

The evaporator coil extracts heat from the indoor air as refrigerant flows through it. Warm air from your home is drawn over the coil, and the refrigerant absorbs the heat, cooling the air before circulating it back inside.

The condenser coil, on the other hand, is located outside and is responsible for releasing the absorbed heat. A fan blows across the condenser coil, expelling the heat into the outdoor air.

Here's a breakdown of the two coils:

The two main types of aircon cooling coils are the evaporator coil and the condenser coil. These coils work together to maintain a comfortable indoor temperature.

The evaporator coil is located in the indoor air handler and extracts heat from the indoor air. Warm air from your home is drawn over the coil, and the refrigerant absorbs the heat, cooling the air before circulating it back inside.

The condenser coil, on the other hand, is located outside and releases the absorbed heat into the outdoor air. A fan blows across the condenser coil, expelling the heat and allowing the refrigerant to return to the evaporator coil.

Here are the key differences between the evaporator coil and the condenser coil:

R-22 air conditioning systems are a thing of the past. They're expensive and difficult to find on the market.
