I have a few rent houses that I would like to make idiot/tenant proof as much as possible. I installed a builder grade Goodman condenser last year in one of them and want to add encapsulated high pressure cutout and low pressure cutout switches to this unit, 42k btu, R22. Looks like 410psi is the standard for the high side. Is that correct? Any recommendations for the low side, would a 35psi cutout be acceptable or something higher like 50psi. My primary concern is keeping the condensing unit from destroying itself if a fan craps out or the freon leaks out.
Also, is it acceptable to install a hard start kit whether or not required by the manufacturer. Seems there is an opinion that a hard start kit would prolong the life of the compressor because of the quicker start-up and less heating of the windings.
From the slumlord standpoint, does it make sense to replace the run caps every few years as preventative maintenance or do the caps typically fail at random time intervals. thanx ...Al
