Types of HVAC Systems
Central Air Systems
Most Common: Uses ductwork to distribute heated or cooled air throughout the home. Includes furnace and central AC units.
Best for: Larger homes with existing ductwork
Heat Pumps
Dual Function: Provides both heating and cooling by moving heat rather than generating it. Very energy efficient.
Best for: Moderate climates, energy-conscious homeowners
Ductless Mini-Splits
Flexible: Individual units for specific rooms or zones. No ductwork required. Highly efficient.
Best for: Room additions, homes without ducts, zone control
Packaged Systems
All-in-One: Heating and cooling components housed in a single outdoor unit. Connects to ductwork.
Best for: Small homes, commercial buildings, space-constrained installations
Hybrid Systems
Smart Choice: Combines heat pump with gas furnace backup. Switches between systems for optimal efficiency.
Best for: Areas with extreme temperature variations
Geothermal Systems
Earth Energy: Uses stable ground temperatures for heating and cooling. Extremely efficient but higher upfront cost.
Best for: Long-term energy savings, eco-conscious homeowners
Understanding Energy Efficiency Ratings
SEER Rating (Cooling)
Seasonal Energy Efficiency Ratio measures cooling efficiency. Higher numbers mean greater efficiency and lower operating costs.
- 13-14 SEER: Minimum efficiency, basic models
- 15-17 SEER: Good efficiency, most popular
- 18+ SEER: High efficiency, premium models
AFUE Rating (Heating)
Annual Fuel Utilization Efficiency measures heating efficiency as a percentage of fuel converted to heat.
- 80% AFUE: Standard efficiency furnaces
- 90-95% AFUE: High efficiency furnaces
- 95%+ AFUE: Condensing, ultra-high efficiency
