  Several factors can cause poor heating performance in your Rinnai Air Conditioner. The temperature setting might be higher than the ambient room temperature, so lower it. A dirty heat exchanger on the indoor or outdoor unit can also cause this, so clean it. Ensure the air filter is clean. Check for blockages in the air inlet or outlet of either unit. Make sure doors and windows are closed, and reduce excessive heat from sunlight by closing windows and curtains. Lastly, low refrigerant levels due to leaks or long-term use can cause poor performance; check for leaks and refill if necessary.

The power switch might be off, so ensure it is turned on. A burned-out fuse could also be the cause, requiring a fuse replacement. If the remote control batteries are dead, replace them.

What to do if Rinnai Air Conditioner starts and stops frequently?
- L
  Lindsay MckenzieSep 3, 2025
  If your Rinnai Air Conditioner starts and stops frequently, it could be due to several reasons: There might be too much or too little refrigerant in the system, so check for leaks and recharge the system. Air or other foreign material might be in the refrigeration system, requiring evacuation and recharge. A system circuit could be blocked, necessitating identification and replacement of the malfunctioning part. The compressor might be broken and need replacement. Lastly, the voltage could be too high or too low, requiring the installation of a manostat to regulate it.
