How to improve cooling performance of Diamond Air Conditioner?
- H
  Haley HayesAug 2, 2025
  If your Diamond Air Conditioner isn't cooling well, several factors could be the cause. First, ensure that your temperature setting is lower than the current room temperature. Check and clean the air filter and the heat exchangers on both the indoor and outdoor units. Make sure that nothing is blocking the air inlet or outlet of either unit. Keep doors and windows closed while the unit is running, and use curtains to block excessive sunlight. Finally, low refrigerant levels could be the issue, so inspect for leaks and refill the refrigerant if needed.

Why does my Diamond Air Conditioner start and stop frequently?

  Mario ClineAug 12, 2025
  If your Diamond Air Conditioner cycles on and off frequently, several issues could be responsible. The refrigerant level might be incorrect, either too high or too low; in this case, check for leaks and recharge the system. Air, non-compressible gas, or foreign material might have entered the refrigeration system, requiring evacuation and recharge. A blocked system circuit could also be the cause, necessitating identification and replacement of the faulty component. Alternatively, the compressor may be failing and need replacement. Finally, voltage fluctuations could be a factor; consider installing a manostat to regulate the voltage.
