Air flow is the most overlooked problem with a Heating & Cooling System.
An undersized or poorly installed duct system can be the root cause of system failures.
HVAC systems are comprised of two major components,
the Refrigerant System and the Air Delivery System.

The major components of the refrigerant system consist of the compressor, the evaporator coil, condenser coil, metering device. This is where the “Freon” is circulated and removes the heat from the building during the cooling cycle. The refrigerant system operating efficiency is based on pressures and temperatures. The pressure and temperatures of the refrigerant system are regulated by air flow.  Too little air flow on the evaporator side will cause lower pressures and temperatures. Most common cause of this, is dirty air filters. On the condenser side, an undersized condenser fan motor or dirty condenser coil will cause higher pressures in the system. There are many other causes of poor air flow, but whatever the cause is, this will reduce the performance, efficiency and life expectancy of the system.

The Air Delivery System is comprised of the Blower Motor and Wheel, the Supply and Return Ducts, the Air Filter(s) and Grills/Registers. Just as the compressor is the heart of the refrigerant system, the blower motor and wheel are the heart of the air delivery system. An improperly sized or poorly installed duct system will reduce the performance and efficiency of the blower motor/wheel reducing the amount of airflow. Reduced air flow will lower pressures in the refrigerant system causing a misdiagnosis of the problem. Possibly resulting in over charging the refrigerant system with refrigerant. This increases the pressures on the compressor reducing its performance, efficiency and life span.

At Desert West Services,
our owners, managers and technicians have gone through extensive training in diagnosing and solving air flow challenges. We have solved air flow problems with a simple fix of replacing a return grill to full duct system replacements. We have invested  in state of the art equipment and tools to diagnose, design and provide solutions for air flow challenges.
