Duct-Free Systems
Duct-free heating and cooling systems provide an energy-efficient solution for homes and businesses, offering targeted comfort without the need for traditional ductwork. These systems are perfect for individual rooms, additions, or buildings without existing duct systems. Just like central HVAC systems, the higher the SEER/SEER2 and HSPF/HSPF2 ratings, the more energy-efficient the unit.
Benefits of Duct-Free HVAC Systems
- Energy Savings – High SEER2 and HSPF2 ratings ensure efficiency and lower utility bills.
- Quiet Operation – No noisy ductwork or compressors.
- Flexible Installation – Ideal for older homes, home additions, and offices.
- Zoned Comfort – Control temperatures independently in different areas.
- Year-Round Use – Provides both heating and cooling in one system.
Understanding SEER2 & HSPF2 Efficiency Ratings
- SEER2 (Seasonal Energy Efficiency Ratio) measures efficiency across the entire cooling season.
- HSPF2 (Heating Seasonal Performance Factor) measures heating efficiency for heat pumps.
- EER2 (Energy Efficiency Ratio) evaluates performance at peak cooling temperatures.
Regional Energy Standards
The Department of Energy (DOE) has established minimum efficiency requirements based on location:
