Finding your air conditioner tucked away in the attic? You're not alone! Many homes utilize attic-installed air conditioning units for various reasons, from space saving to maximizing airflow. But what's the proper name for this often-overlooked component of your home's cooling system? While there isn't one single, universally accepted name, several terms accurately describe it.
Common Names for an Attic AC Unit
The most common terms used to describe an air conditioning unit located in an attic include:
- Attic Air Conditioner: This is the most straightforward and easily understood term. It clearly indicates both the location and the function of the unit.
- Attic Air Handler: This term is often used if the unit in the attic only handles the airflow, with the compressor and condenser located elsewhere (typically outside). The attic unit then circulates the cooled air throughout the house.
- Upflow Air Handler: This term refers to the direction of airflow. In an attic installation, the air handler typically pushes air upwards into the living space.
- Split System Air Conditioner (Attic Unit): This emphasizes that the system is a split system, meaning the components are separated. The attic unit houses the evaporator coil and blower, while the condenser and compressor are external.
What are the different parts of an attic AC unit?
While the entire assembly might be called an "attic air conditioner," understanding the individual components is crucial for maintenance and troubleshooting. A typical attic AC unit, part of a split system, consists of:
- Evaporator Coil: This coil absorbs heat from the air circulated through the unit.
- Blower Motor: This motor circulates air over the evaporator coil and pushes the cooled air into your home’s ductwork.
- Air Filter: This crucial component traps dust, pollen, and other particles, improving air quality and extending the lifespan of the unit.
- Drain Pan and Pump: Condensation forms during the cooling process, and the drain pan collects this water. A pump may be included to remove the water from the unit.
How does an attic AC unit differ from other types?
The primary difference between an attic AC unit and other types lies in its location. Attic installation provides certain advantages:
- Space Saving: It frees up valuable floor space that might otherwise be occupied by a bulky air handler.
- Improved Airflow: In some home designs, placing the unit in the attic can improve airflow distribution throughout the house.
- Quieter Operation (potentially): Depending on the attic's insulation and construction, the noise from the unit may be less noticeable indoors.
However, attic installation also presents some potential challenges:
- Access for Maintenance: Accessing the unit for maintenance and repairs might be more difficult.
- Heat Buildup: The attic's heat can strain the unit, impacting its efficiency and lifespan. Proper insulation and ventilation are crucial to mitigate this issue.
- Potential for Leaks: Leaks in the ductwork are more likely to cause damage in an attic.
What are some common problems with attic AC units?
Several problems can affect attic-based AC units:
- Frozen Evaporator Coil: This can be caused by low refrigerant, restricted airflow, or a dirty air filter.
- Drainage Issues: Clogged drain lines can lead to water damage in the attic.
- Poor Airflow: This can be due to dirty filters, ductwork issues, or a failing blower motor.
- Refrigerant Leaks: These lead to reduced cooling capacity and can cause damage to the compressor.
Understanding the components, potential issues, and various names for your attic AC unit allows you to better maintain your home's cooling system and address any problems that may arise. Remember, regular maintenance and professional servicing are crucial for extending the lifespan and efficiency of your air conditioner, regardless of its location.
