    To many people patting backs.

    Bottom line is it is a job.

    Plan ahead, try to foresee problems.

    Go at it, and do the best you can in the shortest amount of time.

    With priority on doing it correctly and not on time constraints.

    8, 10, 16, 6.5, hours matters not, as long as you can walk away knowing there will be no call back the jib is done.

    I can buy that, I think far to many people just look at how quickly they can do the task at hand. But, when that is done they don't take the time to run the unit and let it cycle on its own to see if it is working properly. You sometimes discover a lot of underlying problems when you take some time and just watch a system while taking measurements. This may take several hours sometimes.

    If you change valve plates and place back in operation, and hit the road, you are really not providing a quality service to the customer.
    You may have met the scope of what was on the work order or was quoted, but did the customer get his problem identified and resolved or just get symptoms fixed temporarily.

    Sadly far to many in this field only look at the symptoms of a problem and fix that, but do not look at Root cause. Which may take some time.
    Often times customers do not understand why it takes so much time to get to the bottom of a problem. They do not understand the dynamics of an HVAC system and think it pretty simple straightforward stuff.

    If you include the time to investigate up front I have found it is much easier than going back after you make repairs and asking for more time.
    How much time elapses before you do not consider it a "Callback"? 6 months, a year?
    We are providing a 3 years parts and labor warranty on our work.
    How long do you provide?

    By the way, I was joking about the 6.5 hours! I have a whole box full of attaboys, but haven't found a bank or store yet that will accept them as payment.

    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.

    Beware of advice given by some guy on the Internet.

    The gaskets were the fiber ones so a decent amount of scraping was required.
    I recovered all 40lbs of refrigerant from the circuit and I replaced the contactor also.
    I arrived on the job at 7:30 and connected my recovery machine. I left at 8:00 to go to my supplier to pick up the valve plates, new gaskets, oil and contactor.
    I was back on the job at 9:30 and my recovery was completed.
    I used 5 psi of nitrogen to push my oil out of the compressor and by 10:00 I was ready to pull off the heads.
    By 12:00 I had all 3 heads off and all fiber gaskets scraped off. I took a 1/2 hour lunch and by 1:30 I had all 3 heads installed and torqued to 85lb/ft.
    My helper was filling the oil while I was torquing the heads.
    I then pressure tested the system with nitrogen and began my vacuum.
    By 3:00 my vacuum was completed and I began charging the system from the high side. By 4:00 truck was packed and unit was running. I ran into another problem since one of the 2 tx valves in parallel wouldn't open so I had to go back the next day to replace the power element.

    If I was doing this under warranty I could have easily done it in 5 hours with my helper or 8 hours alone busting ass.
    I was taking the time to show him how everything worked and what to look for.
    Ours was a rooftop job and not in a mechanical room.
    I`ve heard it might not be legal "EPA" to leave your recover machine running unattended.

    It takes three people to do anything around here. Two do the work, one explains to the crowd of people who showed up when they seen smoke and flames.

    I can't tell you about the USA but we are good to go here if we have the tank overfill switch connected.

    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 clientèle.
    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.
