American Standard AC quality.

[Huiping S.]

One property installed a American Standard 4ton 16 seer, silver AC in Aug-2022. First time stopped to work in 4-28-2024 and disconnected from thermostat without any idea why. Last weekend it stopped to work again but heard loud sounds in the air handler. The exam is the motor burn out. The technician spend all day to figure it out and replaced another motor and it woks now. The AC installer company said the reason is the Inverter motor which government asked to change all AC to have this motor to save energy. Said they replace many motor of AC like us each week. It is under 2 years and very disappointed for the quality. The manufacture asked me to provide an diagnosis  report from a professional to say needs to replace a new AC.  This AC costs $17000 in 2020 and assume will no problem for a long time but most expensive one and shortest time died. 

We have no interest to get a new junk of this same company but like to hear some feedback from investor follows and electric engineer.

Do you think the motor be changed to a non-change speed will resolve the issue? Like all the old AC. 

I was told by 2026, all AC will have this kind of failure Inverter motor to save energy! !

HVAC techs always complain about government mandated changes. Often their complaints have merit. 

Sometimes parts fail and they get replaced and life goes on. I don't think going away from a variable speed motor will make the system last longer, but I'm also not a tech. 

My bigger concern is 17k for an AC system in 2020 or 2022. Just for a condenser and coil, single system? Did you get multiple bids? I'd have to quit the business if I was paying that sort of price for an AC system.
