The evaporator unit of AC systems and heat pump HVAC systems is the indoor component and is located next to the air handler. As residential air conditioning became more popular during the 1970s and 1980s, equipment manufacturers began to seek out less expensive and faster ways of producing coils. The material of which the coils are made is subject to some controversy, as some in the HVAC industry have strong feelings and opinions about which type is better.
Features and Benefits of Aluminum Coils
Aluminum coils for the evaporator unit are less expensive to produce. This allows for a more affordable air conditioner or heat pump. Aluminum is also easy to recycle, and many systems that include aluminum coils produce it with recycled material. Aluminum is less effective at heat transfer compared to copper.
Features and Benefits of Copper Coils
Copper coils are the industry standard and are more durable, less likely to fail, and offer a longer lifespan. They are less subject to coolant leaks, which can make them a more cost effective and environmentally friendly choice over the long run. Copper coils are easier to maintain and repair, but increase the cost of an air conditioner or heat pump system. Some units are vandalized due to the copper fittings within the system.
Why Coils Are Important to HVAC Systems and AC Systems
The coils are the passageway for the chemical coolant. The coils must be in optimal working order for the heat transfer process to take place. A hole or other damage to a coil can render the system inefficient or ineffective at heating or conditioning a home or a building.
Repair vs Replacement of Evaporator Coils
If the evaporator coils on your air conditioner or HVAC system are in need of replacement, you’ll need to consider the reliability, price, durability, and lifespan of the replacement part. If you’re looking for a long-term replacement, copper is the way to go. If you’re looking for the least expensive replacement part, aluminum is it. In many cases, an aluminum part is not able to be repaired at all. In some cases, the entire evaporator component will need to be replaced.
The air conditioner and other types of HVAC equipment have many different components, all of which need to be properly maintained and occasionally repaired in order to efficiently and effectively heat or condition the air.
