Ever since JPS installed the furnace in 2019 at my residence we've had subpar AC in the house. The AC unit was installed 2 years before by another company for reference.
We finally decided to act on this, and JPS technician came out and immediately diagnosed a compressor failure in the AC unit and advised since still under warranty to refer back to the company that installed. JPS advised an ~$3000 cost for them to replace. I had mentioned that i noticed airflow had been suboptimal in cooling phase to the tech but was told this is normal.
After consulting with multiple inept techs at the other company and being given the run around from them I found out how to access the dealer settings in my Daikon One thermostat that JPS had installed. CFM was showing at 600 for a 2.5 ton AC unit and from my readings and understanding should have been at least 50% higher towards 1000CFM. Since the Daikon one wouldn't let me adjust settings i ultimately said screw it and re-installed my nest thermostat and reseting the furnace dipswitches as per the manual and low and behold my AC is working fine now.
Either Daikon one thermostat was not setup correctly in first install by JPS, and was not even reviewed nor was the airflow issue reviewed on site visit. I am very versed in mechanical and electrical systems and solved the issue but for anyone without a trade knowledge this would have possibly cost them over $1000 without resolution, and upwards of $3000-$5000 if a full unit was replaced- Which would not have solved the issue.
