Regular maintenance and proper checks will contribute to the safety, energy efficiency, and extended service life of your air source heat pump. By ensuring that your heat pump operates optimally, you can enjoy comfortable indoor temperatures while minimizing energy consumption and potential equipment wear and tear.

Inverter EVI Heat Pump, featured with cost-effectiveness, can be used in extremely cold area with climate temperature as low as -25℃ for heating/cooling, and domestic hot water.

Before starting the heating system with your air source heat pump, it's important to conduct thorough checks from the perspectives of safety, energy savings, and equipment service life. Here's a breakdown of the checks to perform under each aspect:

1. Safety Checks:

Electrical Connections:

Inspect all electrical connections, wires, and terminals for signs of wear, corrosion, or damage. Ensure that all connections are tight and secure. Loose connections can lead to electrical issues and safety hazards.

Isolating Power:

Confirm that the heat pump is safely isolated from the electrical supply before performing any maintenance or checks. This is crucial for preventing electrical accidents.

Refrigerant Lines:

Check the refrigerant lines for any signs of damage, leaks, or insulation deterioration. Leaking refrigerant can be hazardous to both your health and the environment. If you suspect a refrigerant leak, contact a qualified technician for repairs.

Condensate Drainage:

Ensure that the condensate drain lines are clear and unobstructed. Clogged drain lines can lead to water damage and potentially cause safety hazards.

Ventilation and Airflow:

Verify that the outdoor unit has proper ventilation and airflow. Remove any debris, leaves, or obstructions that could interfere with safe operation.

2. Energy Savings Checks:

Air Filters:

Clean or replace the air filters as needed. Dirty filters restrict airflow and reduce the heat pump's efficiency. Clean filters improve energy savings and indoor air quality.

Coil Cleaning:

Inspect and clean both the evaporator and condenser coils. Dirty coils reduce the efficiency of heat exchange. Clean coils ensure that the heat pump operates efficiently, saving energy.

Thermostat Calibration:

Test the thermostat for accuracy and responsiveness. Ensure that it's set at the desired temperature and programmed to optimize energy savings.

Ductwork Inspection:

Examine the ductwork for leaks, disconnected sections, or damaged insulation. Properly sealed and insulated ducts are vital for energy efficiency, as they help minimize heat loss.

Refrigerant Pressure:

Check the refrigerant pressure to ensure it's within the manufacturer's recommended range. Proper refrigerant levels are crucial for the heat pump's efficiency. Low pressure can lead to decreased energy savings.

3. Equipment Service Life Checks:

Expansion Valve and Reversing Valve:

Inspect these valves for proper operation and any signs of damage or malfunction. Ensure they are functioning correctly to control the refrigerant flow and switching between heating and cooling modes.

Fan Blades and Motors:

Check the fan blades and motors for damage or signs of wear. Lubricate fan motors if necessary, and ensure that blades are clean and balanced. Proper fan operation contributes to the longevity of the equipment.

Regular Maintenance:

If you haven't had a professional service recently, consider scheduling an annual maintenance service with a qualified HVAC technician. They can perform comprehensive inspections, calibrations, and address any issues that may affect the heat pump's service life.

Ambient Conditions:

Be mindful of extreme weather conditions. In extremely cold climates, make sure the heat pump is adequately protected from ice and snow accumulation, and in very hot climates, ensure that the outdoor unit has proper shading to avoid overworking the system.
