Key Components:
- A4AC5 Air Conditioner: An outdoor unit designed for efficient cooling, operating quietly at 71-74 dB.
- A4AH4 Air Handler: An indoor unit featuring an all-aluminum coil, factory-installed flow control, fully insulated galvanized steel cabinet, and multi-speed fan motors for consistent air distribution.
- Heater: Field-installed component for heating functionality.
Energy Efficiency (SEER2):
SEER2 (Seasonal Energy Efficiency Ratio 2) measures the total heat removed from the conditioned space during the annual cooling season. This system boasts a 15.2 SEER2 rating, indicating high energy efficiency. The new M1 testing procedure for SEER2 increases external static pressure by a factor of five to better reflect real-world installation conditions.
Compared to older 10 SEER units, this system can provide significant energy savings. Higher SEER ratings directly correlate with greater energy efficiency, leading to lower operating costs.
Operating Stages:
- Single-Stage Systems: Operate at a single speed, turning off completely once the desired temperature is reached.
- Two-Stage Systems: Alternate between a low and high speed, offering improved comfort and efficiency by running at a lower speed for longer periods.
- Variable Speed Systems: Continuously vary their speed to maintain the ideal temperature, providing the highest level of comfort and efficiency. These systems run more continuously, similar to a dimmer switch, automatically adjusting output as needed.

4. Setup and Installation
Installation of this HVAC system requires specialized knowledge and tools. It is strongly recommended that installation be performed by a certified HVAC professional.
General Installation Steps (for professional reference):
- Site Preparation: Ensure adequate space and proper foundation for the outdoor condenser unit and indoor air handler.
- Ductwork Connection: Connect the air handler to the existing or new ductwork system.
- Refrigerant Line Installation: Install and connect the refrigerant lines between the condenser and air handler. Ensure proper evacuation and charging of the system.
- Electrical Wiring: Connect the units to the appropriate power supply according to wiring diagrams and local electrical codes.
- Condensate Drain: Install and properly route the condensate drain line from the air handler.
- Heater Installation: Integrate the field-installed heater into the air handler as per manufacturer instructions.

5. Operating Instructions
Once installed, your RunTru HVAC system is controlled primarily through your home's thermostat. Familiarize yourself with your thermostat's specific functions for optimal use.
Basic Operation:
- Cooling Mode: Set your thermostat to 'Cool' mode and select your desired temperature. The system will activate the air conditioner to cool your home.
- Heating Mode: Set your thermostat to 'Heat' mode and select your desired temperature. The system will activate the heater to warm your home.
- Fan Mode: You can typically set the fan to 'Auto' (runs only when heating/cooling) or 'On' (runs continuously for air circulation).
For systems with multiple stages or variable speed, the unit will automatically adjust its operation based on the thermostat's demand and the system's internal logic to maintain comfort and efficiency.
6. Maintenance
Regular maintenance is crucial for the longevity, efficiency, and optimal performance of your RunTru HVAC system. It is recommended to schedule professional maintenance annually.
User Maintenance:
- Air Filter Replacement: Check your air filter monthly and replace it every 1-3 months, or more frequently if you have pets or allergies. A clean filter ensures proper airflow and system efficiency.
- Clear Outdoor Unit: Keep the area around the outdoor condenser unit free from debris, leaves, and vegetation to ensure proper airflow.
- Condensate Drain: Periodically check the condensate drain line for clogs.
Professional Maintenance (Recommended Annually):
- Coil cleaning (evaporator and condenser coils)
- Refrigerant level check and adjustment
- Electrical connection inspection and tightening
- Blower motor and fan inspection
- Drain line cleaning and inspection
- Overall system performance check
