How to troubleshoot excessive noise in my SystemAir SYSCROLL 20-35 Air Heat Pump?
- K
  Karen RamosAug 18, 2025
  If your SystemAir Heat Pump is making excessive noise, start by checking the clamping brackets of the lines for vibration. If the noise is a whistler emitted by the thermostatic expansion valve, consider refilling. Inspect the dehydrating filter. If the compressor is noisy, it may have seized bearings, requiring a compressor replacement. Also, ensure that the compressor’s locknuts are tightened.

  Clinton HallAug 21, 2025
  If your SystemAir Heat Pump activates the HP alarm and stops, it could be due to several reasons. Check the operation of the pressure switch, and replace it if it’s defective. Ensure that the delivery valve is fully open; if it’s faulty, replace it. If there are substances with condensable gases in the circuit, drain the circuit. Also, check the condenser fan's cables and motor; if they are defective, repair or replace them.

What causes low oil level in the compressor of my SystemAir SYSCROLL 20-35 Air Heat Pump?
- L
  Lauren JenningsSep 10, 2025
  If you observe a low oil level in the compressor of your SystemAir Heat Pump, it could be due to one or more gas or oil leaks in the circuit; identify and remove these leaks. It may also indicate a mechanical failure of the compressor, requiring intervention from a Service Centre. Another potential cause is an anomaly of the oil heater of the compressor’s base; check the electric circuit and the resistor of the heater of the motor base, and replace any defective components.
