Common Installation Mistakes

You must know common installation mistakes when setting up your new AC in Chandler, AZ.

Two of the most common mistakes affecting your AC's cooling efficiencyAC are inadequate insulation and improper ductwork installation.

  • Inadequate insulation can lead to air leakage, causing the cooled air to escape and leaving your room warmer than desired.
  • However, improper ductwork installation can cause restricted airflow, reducing the cooling capacity of your AC.

To avoid these issues, ensure your home is insulated correctly, with sufficient insulation in the walls, attic, and floors.

Additionally, it's essential to have your ductwork installed correctly, ensuring no leaks or restrictions can hinder the airflow.


Insufficient Refrigerant Levels

Your AC's insufficient refrigerant levels can significantly impact its cooling efficiency and overall performance. When there isn't enough refrigerant in the system, your AC will struggle to cool your home effectively, and you may notice that the air coming out of the vents isn't as cold as it should be.


  • One cause of low refrigerant levels is refrigerant leaks. These leaks can occur in the coils, connections, or valves of your AC system. It's essential to address these leaks promptly to prevent further damage and ensure optimal cooling performance.
  • Clogged air filters are another potential issue that leads to low refrigerant levels. When the filters are dirty or blocked, they restrict the airflow, causing the AC unit to work harder and potentially leading to decreased refrigerant levels. Regularly cleaning or replacing your air filters can help prevent this problem.

If you suspect your AC has insufficient refrigerant levels, it's best to contact a professional HVAC technician to diagnose and resolve the issue.


Faulty Thermostat or Sensor

To effectively troubleshoot a faulty thermostat or sensor, check the connections and ensure they're secure. A faulty thermostat or sensor can cause issues with your HVAC system, like inaccurate temperature readings or a complete failure to cool or heat your home.

Begin by examining the wiring connections to ensure they're tight and secure. Loose connections can disrupt the communication between the thermostat and the sensor, leading to malfunctions.

The next step is to check the sensor calibration to see if the connections are secure. A sensor not calibrated correctly can provide inaccurate readings, causing the thermostat to operate improperly. Consult the manufacturer's instructions or contact a professional technician for guidance on calibrating the sensor.



In conclusion, if your new AC isn't cooling in Chandler, AZ, there could be common installation mistakes, insufficient refrigerant levels, or a faulty thermostat or sensor.
