What is the AC Unit in the Attic Called?
An air conditioning unit located in an attic is typically called an attic air conditioner or, more technically, a split system air conditioner with the air handler in the attic. While the term "attic AC unit" is commonly used and easily understood, it's helpful to understand the more precise terminology to better grasp the system's components.
Let's break down why these terms are used and clarify some potential confusion:
What are the different parts of an attic AC system?
A split system air conditioner, as the name suggests, is split into two main parts:
-
Condenser Unit: This is the outdoor part of the system, containing the compressor, condenser coils, and fan. It's responsible for releasing heat absorbed from inside your home. While not in the attic, it's crucial to the entire system's functionality.
-
Air Handler (or Evaporator Coil and Blower): This is the indoor part located in your attic. It circulates cool air throughout your home. This unit contains the evaporator coil, which absorbs heat from the air, and a blower fan that pushes the cooled air through your ductwork. This is the part most people refer to when asking "What is the AC unit in the attic called?"
Therefore, while "attic AC unit" is a convenient shorthand, "air handler" (or sometimes "evaporator coil unit") is more accurate when referring specifically to the component inside the attic.
Why is my AC unit in the attic?
There are several reasons why homeowners might have their air handler unit located in the attic:
-
Space Constraints: If there isn't enough space inside the home to house the air handler, the attic provides a convenient alternative.
-
Noise Reduction: Placing the air handler in the attic helps to reduce noise levels within the living spaces.
-
Existing Ductwork: An existing ductwork system might already be in place in the attic, making it a more cost-effective choice to use the attic for the air handler.
What are the pros and cons of having an AC unit in the attic?
Pros:
- Saves Space: It frees up valuable floor space in the home.
- Potentially Quieter Operation: Reduces noise pollution in living areas.
Cons:
- Increased Maintenance Difficulty: Accessing and maintaining the unit can be more challenging.
- Heat Exposure: The attic can become extremely hot, potentially impacting the efficiency and lifespan of the unit. Proper insulation and ventilation are crucial.
- Potential for Leaks: Leaks in the ductwork can lead to moisture problems in the attic.
How do I know if my attic air conditioner needs maintenance?
Regular maintenance is crucial for the longevity and efficiency of any air conditioning system. Signs that your attic air conditioner might need attention include:
- Unusual Noises: Strange banging, rattling, or squealing sounds.
- Reduced Cooling Capacity: Your home isn't getting as cool as it used to.
- Increased Energy Bills: Your energy consumption has significantly increased.
- Frozen Coils: Ice buildup on the evaporator coil is a serious issue that requires immediate professional attention.
What are common problems with attic AC units?
- Overheating: As mentioned previously, the attic's high temperatures can cause the unit to overheat, reducing its efficiency and potentially leading to damage.
- Moisture Problems: Poor insulation or leaks in the ductwork can lead to moisture buildup in the attic, potentially causing mold and other problems.
- Dust Buildup: Dust and debris can accumulate in the unit, restricting airflow and reducing efficiency.
Remember, regular maintenance and addressing problems promptly will ensure your attic air conditioning unit runs smoothly and efficiently for years to come. If you suspect a problem, it's always best to call a qualified HVAC technician for professional help.
