Our compressor supplier requires us to fill out this startup report when replacing compressors.
I use a similar report during my annual PM's and whenever a system is serviced.

I have never tried Compref but they're certainly cheaper than Totaline.
I bought a 06DX537 last week for $1500 which comes with a 3 year warranty.
I like using them because they are close to most of my clientθle.
I try not going towards the east end since I'll usually get stuck in traffic during peak hours.
I can call G&S almost any time and be at their door in one hour picking up a compressor.
They are reasonable with their warranty also since I needed to replace one which let go after a crankcase heater died and flooded back the compressor.
I like dealing with family run businesses whenever I can.
Thanks-i may try them instead of compref then.Compref used to have an office in calgary here but closed it and someone told me they were using GShermetique and had good service.Thanks again
