Refrigerant renewal, $350
Recommended for systems that have already undergone a chemical wash but are still not performing as well as before.
- • Equipment Check: Gather all necessary tools and equipment, including a vacuum pump, refrigerant cylinders, refrigerant scales, manifold gauge set, and service wrenches.
- • Service Valves: Locate the service valves on the outdoor unit. These valves are typically covered by protective caps.
- • Manifold Gauge Connection: Attach the manifold gauge set to the service valves. The blue hose connects to the low-pressure side and the yellow hose will be used for vacuuming and charging refrigerant.
- • Ensure System is Empty: Check the manifold gauge to ensure all refrigerant has been evacuated and the system pressure is at 0 psi.
- •Vacuum Pump Connection: Disconnect the yellow hose from the recovery machine and connect it to the vacuum pump.
- •Initiating the Vacuum: Activate the vacuum pump to begin the evacuation process. The vacuum will remove any remaining refrigerant, moisture, and air from the system.
- •Duration: Maintain the vacuum for 15-30 minutes to ensure complete removal of contaminants. Check the manifold gauge; a proper vacuum is typically indicated by a pressure reading of -30psi or lower.
5. Checking for Leaks
• Hold the Vacuum: After the vacuum process is complete, turn off the vacuum pump and observe the pressure reading on the gauge for a few minutes. If the pressure remains stable, the system is likely free of leaks. If the pressure increases, it indicates a leak that must be located and repaired before proceeding.- • Calculating Refrigerant Quantity: Determine the factory-specified refrigerant charge for the system, typically noted on the data plate of the outdoor unit. Adjust for the length of the piping as necessary, using guidelines found in the manufacturer’s installation manual.
- • Refrigerant Cylinder Preparation: Place the refrigerant cylinder on the scales and connect the yellow hose to the cylinder. Open the cylinder valve slightly to purge air from the hose, then close the valve.
- • Initiating Charging: Open the low side valve on the manifold gauge to allow the refrigerant to flow into the system. Monitor the scales to ensure the correct amount of refrigerant is added.
- • Finishing the Charge: Once the specified weight of refrigerant has been charged, close the manifold gauge valves, and disconnect the hoses.
- • Re-check for Leaks: Perform a final leak check to ensure system integrity.
- •Start-up the System: Restore power to the air conditioning unit and start it. Observe the operation for a few minutes to ensure it is functioning correctly.
- • Performance Check: Measure the temperature drop across the indoor unit to assess cooling performance, including suction line temperature and pressure, FCU return air and off-coil air temperatures, and superheat value.
- • Record Keeping: Document the process, including the amount of refrigerant charged, and any repairs carried out.
- • Clean-up: Ensure all caps are replaced on service valves, tools are collected, and the work area is clean.

- • Removal and Dusting: Carefully remove the air filters from the FCU. Dust off loose debris using a soft brush or a vacuum cleaner.
- • Washing: Wash the filters with water to remove accumulated dirt and grime. Allow the filters to dry completely before reinstalling them.
- • Dust and Debris Removal: Use a vacuum cleaner to remove dust and debris from the fan coil and blower. In some cases, a soft brush may also be used to gently clean the coil fins.
- • Checking for Obstructions: Ensure that there are no obstructions that could impede the airflow or the operation of the blower.
- • Flushing the Drain Pan: Clean the drain pan, removing any standing water and debris to prevent Mold and algae growth.
- • Clearing the Drainage Pipes: Flush the drainage pipes with wet vacuum cleaner to ensure they are clear of blockages.
5. Inspection of Electrical Components
• Wiring Check: Inspect all electrical connections and wiring for signs of wear or damage. Tighten any loose connections.- • Functionality Test: Test the electrical components and controls of the FCU to ensure they are functioning correctly.
- • Pressure Check: Use a manifold gauge to check the refrigerant pressure. Low levels may indicate a leak or that the system requires recharging.
- • Leak Inspection: If low refrigerant levels are detected, a leak test may be conducted to identify and rectify any issues. Additional cost applies.
- • Cooling Efficiency: Measure the temperature drop across the indoor unit to assess cooling performance, including suction line temperature and pressure, FCU return air and off-coil air temperatures, and superheat value.

- • Power Off Ensure the air conditioning system is completely powered off to avoid any electrical hazards during the cleaning process.
- • Remove the Top Cover: The top cover of the outdoor unit is removed to fully access internal components such as the condenser coils and fan blades.
- • Protect Electronic Parts: Critical electronic components, including wiring and the control panel, are carefully covered with waterproof material to protect them from water and chemical exposure during the cleaning process.
- • Remove Fan Blade: The fan blade is carefully removed to allow better access to the condenser coils and to ensure a more thorough cleaning.
- • Inspect Components: Conduct a thorough inspection to check for any visible signs of damage or wear and to assess the overall condition of the unit before applying any chemicals.
- • Prepare Alkaline Solution: An alkaline chemical cleaner, initially with a pH of 13, is prepared from a concentrate according to the manufacturer's instructions before mixing. This solution is based on sodium or potassium hydroxide, known for their effective cleaning properties in removing grease, dirt, and biological debris.
- • Spray Chemical Cleaner: The diluted alkaline solution is evenly sprayed over the condenser coils from both sides and other accessible components. This cleaner is designed to break down accumulated dirt, mould, and debris effectively.
- • Dwell Time: Allow the chemical solution to sit for about 15 to 30 minutes to penetrate and loosen all the grime.
- •Two Technicians Required: The complexity and safety requirements of the task necessitate the presence of two trained technicians to efficiently and safely handle the equipment and cleaning process.
- •Rinsing: After the chemical has done its work, use a water jet to thoroughly rinse the entire unit, specifically the condenser coils from both outside and inside, to ensure maximum reach and removal of loosened debris and chemical residue.
- • Use Wet Vacuum Cleaner: Since the condensing unit (CU) is typically located at multi-storey buildings, a wet vacuum cleaner is used to remove all the awater from washing. This prevents any dripping that could affect the neighbours below.
- • Reassemble the Unit: Once the cleaning is completed and the unit is dry, replace the fan blade and remove all protective coverings from the electronic components. The top cover is then replaced.
- • System Test: Restore the power and turn on the air conditioning system to ensure it operates correctly. Check the airflow and temperature to confirm that the unit is functioning efficiently.
