Generally these soft start devices are installed to lower the start-up current if you have installed a generator or some other alternate power source. I know they may extend the life of the compressor but doubling it or any fixed extension, there is really no way to tell. They are also good to quiet down the condensor giving your neighbor some relief if their bedroom window is near your unit. If you really want to extend the life of your condensor besides the soft start you also might want to install the Rectorseal 96424 Surge Protector RSH-50 VRMDC with Breaker Model: RSH50VRMDC. The RSH-50 VRMDC KIT combines the VRM60A, RSH-50, & 60A disconnect breaker in a NEMA 3R enclosure, for an all-in-one equipment solution. The RSH-50 uses Gas Discharge Tube (GDT) Technology along with Thermally Fused Metal Oxide Varistors (TMOV) for ultimate protection. It also disconnects the power on a brown-out or high voltage event protecting the condensor.

Also, last I looked, If you are an original owner then you get the 10 year warranty on the compressor and related parts. For subsequent homowners, its 5 years.
On my new Carrier Infinity Greenspeed, the warrenty is now fully transferrable. |
I have replaced the contactor and capacitor(made in USA). Now if the fan fails the HPCO should take it out. If the sensor is bad then it may kill compressor unless the MicroAir senses abnormal current which I believe it does.
Reducing the peak inrush current by 50% or more will significantly extend the life of the compressor. Lower current will reduce insulation breakdown and stress on bearings and other components. The surge protector is a good idea.
Now if the evaporator has a leak that can't be repaired then you are screwed unless you can find a replacement. That will be unlikely since 410A equipment is no longer in production. You will have to replace the whole system.
