Airflow And Refrigerant Charge: When Optimized, These 2 Factors Will Contribute To Peak System Performance

Last updated 2 years ago

By Greg, Pacific Aire Comfort Advisor

Ensuring optimal airflow and refrigerant charge in your HVAC system is a vital step in maintaining energy efficiency and comfort in your home. In order to satisfy your needs, and avoid high energy costs, you should have your air conditioner professionally serviced every year in order to diagnose problems quickly and properly, and avoid early system failure.

Airflow
The first thing that your technician or contractor should check is airflow. Common contributors to problems can include:
 

  • Blockages or obstacles in air passages
  • Not having enough ducts, as the ideal duct system would have a return air register in every room.

Most homes have approximately two or three return air registers providing circulation throughout the house. which can be remedied by installing louvered grilles in doors and walls or installing new ducts.

When installing new HVAC equipment, ducts should be sized correctly, as ducts that are too large or too small will also reduce efficiency and comfort in your home. This problem can also cause damage to your system's compressor and fans, if your HVAC system is constantly switching on and off. Leaks in ducts should also be repaired and sealed, applying the correct method and materials to seal them effectively.

Refrigerant
The other common issue with heating and cooling systems is incorrect refrigerant level, either too high or too low. Your technician should always first analyze airflow, as airflow and refrigerant charge operate conjointly.

If there is a leak in your system, the leak should be repaired and then tested by a qualified technician, who will know how to match the refrigerant levels to the manufacturer's specifications. Simply adding or removing refrigerant charge when your levels are incorrect will not solve your problems, but will possibly cause further efficiency issues and damage to your system.
