With 18,000 BTU of cooling power, this system can effectively reduce indoor temperatures even during peak summer conditions, provided the space is properly insulated and sized appropriately.

Benefits of 1.5 Ton Capacity

• Suitable for larger bedrooms or open living areas
• Efficient for commercial office rooms
• Ideal for residential additions
• Balanced cooling without oversizing

Correct sizing is critical for maximizing efficiency and preventing unnecessary cycling.

Heating Capability – Heat Pump Efficiency

The HES-18-HD-A is a heat pump system, meaning it can both cool and heat by reversing the refrigeration cycle. This dual functionality provides year-round climate control.

Heat Pump Advantages

• Energy-efficient heating compared to electric resistance heaters
• Lower operational costs during mild winter conditions
• Consistent indoor temperature control
• Single-system convenience

Heat pumps are particularly effective in regions with moderate winters, offering a practical solution without separate heating equipment.

16.5 SEER Energy Efficiency

The system features a 16.5 SEER rating, reflecting strong seasonal efficiency compared to older HVAC systems that often operate at 13 SEER or below.

What 16.5 SEER Means

SEER measures cooling output divided by total energy consumption during a cooling season. A higher SEER rating indicates better efficiency.

With 16.5 SEER, this system provides:

• Lower electricity usage compared to older units
• Improved long-term cost savings
• Reduced environmental impact
• Balanced performance and affordability

For property owners managing multiple units, such as apartments or student housing, efficiency plays a significant role in controlling operating expenses.

Inverter Compressor Technology

One of the most important features of the MULTI MANUFACTURING HES-18-HD-A is its high efficiency inverter compressor.

Traditional HVAC systems operate in an on/off cycle, while inverter compressors adjust speed based on demand.

Advantages of Inverter Technology

1. Reduced energy consumption
2. Smoother temperature control
3. Lower startup power surge
4. Improved longevity
5. Quieter operation

By modulating compressor speed, the system maintains stable indoor conditions without constant cycling.

Low Amp Draw DC Outdoor Motor

The outdoor heat pump unit incorporates a DC motor designed for low amp draw.

Benefits of DC Motor Technology

• Reduced electrical load
• Improved energy efficiency
• Lower operational noise
• Enhanced durability

Lower amp draw is especially beneficial in properties where electrical infrastructure may be limited or where multiple systems operate simultaneously.

Noise Level – 55 Decibels

The system operates at approximately 55 decibels, placing it within a moderate and comfortable noise range.

For context:

• Normal conversation averages 60 decibels
• Quiet office environments range between 40–50 decibels

At 55 decibels, the unit delivers:

• Comfortable background sound levels
• Suitable performance for apartments and offices
• Minimal disruption in residential settings

Quiet inverter compressors further enhance overall acoustic comfort.

Design and Dimensions

The compact structure measures:

• 12.5 inches depth
• 31.6 inches width
• 21.8 inches height

Its metal exterior contributes to durability and resistance against environmental exposure.

The streamlined design allows flexible placement in:

• Utility areas
• Exterior wall mounts
• Rooftop installations
• Dedicated HVAC closets

Its manageable size makes it adaptable for modular buildings and prefabricated housing.

Refrigerant – R-410A

The HES-18-HD-A utilizes R-410A refrigerant, widely used in modern HVAC systems.
