Thanks guys for all the responses. All of you hit it right on the head. "POOR MAINTAINENCE" On our Carrier 30GT unit...
Service crew only responded when we had a problem. Only once a year for maintenance and that was only to clean the fins. I later learned to clean them once a week with plain water but the damage was done. Their cleaner was too caustic and caused severe damage to fins years ago before my time there. On one of our service calls at night the machinery had gone down and when the owner of the service company responded and saw me reading the operating and trouble code manual and said " why are you wasting your time with that" I knew we were in trouble.
We went back to Carrier for service and maintenance but it was a little too late. We now have a rental unit (trane 200 ton with 2 screws, I think they bought out a small division of trane units) which is doing fine. We will probably get a permanent unit from Carrier once the engineers size up the building. I think it might be a 30GX with screws.
Thanks for all the help and tips from everyone. Reading other posts from this site regarding maintenance, oil changes and checking the quality of oil after changing it and other matters really has helped in our decision.
Fortunately the owner and manager has learned that trying to save a few dollars changing service companies ( we will stick with the manufacturer for service and maintenance) costs alot more in the long run.
Just a tidbit of information for anyone who has thought of it.... We were sold a bit of goods on compressor "snake oil --- compress sheild" and of course the guarantee of picking up 70 to 100 tons of cooling and a year guarantee on all 7 compressors. Well in a period of 5 to 12 months 3 compressors went south and in that time didnt see any increase in operating quality or savings on electric costs. Just food for thought......
Thanks again
