Why AERMEC Air Conditioner unit does not start?
- G
  Garrett SimmonsAug 14, 2025
  The AERMEC Air Conditioner unit might fail to start due to several reasons: * Lack of electrical voltage, requiring a voltage check and inspection of upstream safety systems. * The master, remote, control panel, or main switch being OFF, needing to be set to ON. * An uninstalled or unwired flow switch, which needs proper installation, avoiding bridging the contacts to prevent damage in case of insufficient water. * Low power supply voltage, necessitating a check of the power supply line. * A broken compressor remote control switch coil, faulty electronic circuit board, faulty peak condenser, or faulty compressor, each requiring component replacement.

What to do if AERMEC Air Conditioner compressor stops due to the intervention of the protections?
- J
  Jamie AndersonAug 17, 2025
  If the AERMEC Air Conditioner compressor stops due to the activation of its safety mechanisms, it could be due to: * Excessive flow pressure. * Low intake pressure. * Low power supply voltage. * Poorly tightened electrical connections. * Operation outside operating limits. In these cases, check the operating limits using the graphics. It may also be due to a malfunctioning pressure switch (replace the component), intervention of circuit breaker protection (check the power supply voltage and calibrations, and the electrical isolation of the windings), or flow switch intervention (check water flow rate).

Why AERMEC Air Conditioner compressor has high discharge pressure?
- L
  Laura WilliamsAug 21, 2025
  High discharge pressure in the AERMEC Air Conditioner's compressor can be caused by: * High external air temperature. * High utility inlet water temperature. In such cases, check the operating limits using the graphics. * Insufficient air or water flow. Control the operation of the fans, the cleanliness of the coil, the operation of the pump (speed), and the cleanliness of the filter. * Anomalous fan operation (check or replace if broken). * Air in the hydraulic system (vent the circuit). * Too much refrigerant gas charged (restore the correct charge).

Why AERMEC Air Conditioner has poor yield?
- P
  pjohnsonAug 25, 2025
  Poor yield in the AERMEC Air Conditioner can stem from several causes: * Lack of refrigerant. * Dirty coils. * Clogged water filter. * Improper appliance dimensioning. * Operating outside the specified limits. To address this, check for refrigerant leaks and replenish the refrigerant, clean the coils and the filter, check the appliance's performance, and verify that the operating limits are within the ranges specified in the graphics.

What causes noises and vibrations in AERMEC Air Conditioner?
- M
  Marissa ThompsonAug 27, 2025
  Noises and vibrations in your AERMEC Air Conditioner can arise from: * Contact between metallic bodies (check). * Weak support (strengthen). * Loose screws (tighten the screws).
S
Sandra RoweAug 31, 2025
Why AERMEC Air Conditioner compressor has low discharge pressure?
- M
  Mary ThomasAug 31, 2025
  Low discharge pressure in the AERMEC Air Conditioner's compressor can occur due to: * Low outside air temperature. * Low water inlet temperature. Check the operating limits using the graphics. * Moisture in the refrigerant circuit (empty and restore the gas charge). * Air in the hydraulic system (bleed the circuit). * Insufficient gas load (restore the correct load).
M
Megan HallSep 3, 2025
Why AERMEC Air Conditioner compressor is noisy?
- A
  Ashley WalshSep 3, 2025
  A noisy compressor in the AERMEC Air Conditioner can be attributed to: * Liquid return to the compressor (check). * Inadequate fixing (check). * Inverted phase (invert a phase).
B
Barbara DawsonSep 7, 2025
Why AERMEC Air Conditioner has high intake pressure?
- M
  Melissa HernandezSep 7, 2025
  High intake pressure in your AERMEC Air Conditioner can be caused by: * High external air temperature. * High utility inlet water temperature. * Thermostatic expansion valve being too open or damaged. Check the operating limits using the graphics and adjust or replace the valve if damaged.

Why AERMEC Air Conditioner has low intake pressure?
- K
  Karen SmithSep 10, 2025
  Low intake pressure in the AERMEC Air Conditioner may result from: * Utilities low inlet water temperature. * Low outside air temperature. * Thermostatic expansion valve damaged or blocked. Check the operating limits using the graphics and adjust or replace if damaged. * Insufficient water flow. * Insufficient air flow. Control operation of the fans, cleanliness of the coil, pump operation (speed), and filter cleanliness.
