I have a Carrier Infinity system with a 24ANA160 5 Ton AC unit and a 58MVC-120-20 furnace. In the rooms with the longest duct runs we have heating/cooling variances of between 5-8 degrees from the thermostat. I believe we have poor airflow. The contractor disagrees with me but does not offer much in the way of solutions on the temperature variance and says it is withing "industry standards"
Here is a picture of what I am getting currently.
Is the static pressure good enough when in high heat mode?
The air delivery Chart says high heat mode should be 1900 cfm from static pressures between .1 and .5. After .5 the cfm drops off. Would higher static pressures give me more airflow or higher velocity of the current airflow to adequately heat the rooms I have issues with?
