Buying Guide for Mini Split Attic Air Handlers
When selecting a mini split attic air handler, consider the following key factors to ensure an optimal fit for your space and comfort needs.
Capacity and Size
BTU capacity should match your attic’s size and insulation. Higher BTUs are necessary for larger or poorly insulated attics. Over-sizing wastes energy; under-sizing leads to inefficient performance.
Energy Efficiency (SEER Ratings)
Look for models with high SEER2 ratings (Seasonal Energy Efficiency Ratio) for energy savings. Modern units feature inverter technology that adjusts compressor speed improving efficiency and lowering power bills.
Heating Capability
If your attic requires heating, choose units with heat pump functionality capable of efficient operation in low ambient temperatures, especially important for colder climates.
Installation Requirements
Consider the ease of installation. Some units support DIY installations, while others require professional service, especially if brazing line sets or installing multi-position handlers.
Control Features
WiFi compatibility, remote controls, and multiple operating modes (sleep, turbo, eco) enhance convenience and personalized comfort. Some models support voice assistant integration for smarter management.
Noise Levels
Attic air handlers should operate quietly to avoid disrupting the home. Look for units specifying low noise in decibels, especially if your attic is near living spaces.
Environmental Impact
Consider refrigerants used; newer R32 refrigerants are more eco-friendly than traditional options, reducing environmental footprint.
Multi-Zone Capability
Multi-zone systems allow independent temperature control in different attic sections or adjacent rooms, providing tailored comfort but requiring more complex installation.
