    When you disconnect your system from power in the fall do you have the power turned on at least 24 hours before you turn the A/C on? Just asking as I think that Armstrong uses the capaciter in the off cycle as a crankcase heater of sorts and if power was not on for 24 hours then the unit could have had trouble starting up and locked itself. Just a thought.

    I also agree that if the compressor is changed the manufacturer may check it and determine that it is OK and charge the dealer for it. A hard start is an assessory that is availiable with most units new or old from the manufacturer. They are needed many times for voltage variances. I would thing that if one was added and the system is working properly you shaoul be just fine. I also understand your concerns but this is when you need to rely on your contractor to do the right thing for you. If you don't trust there advise then I would try a different contractor.
    Its a good Life!

    My exact first thought when I read that as well. There may very well be something that got the proverbial ball rolling for this compressor to now require hard start components. Then again, if there is no electrical issue from the electrical supplier and there are no problems with the electrical circuit to the outdoor unit, the hard start capacitor could very well be able to be taken off and the compressor never have a problem again. The question is; why would you do that? Start components have been "removed" from outdoor units as a standard item due to cost restrictions. All that has been done here is that an eliminated component has been put back into the system.

    Thought

    How about this thought....The original cut (short) of the power line was stopped at the main circuit board so I doubt that had anything to do with the issue. However, the electrician fixed the problem (in the Spring before the AC was turned on), he then flipped the outside power on to check his work, tried to start the unit, the unit came on and he walked away (fan only). The compressor never had the 24 hours to heat properly and locked going forward. If I recall this time around I wondered why the outside power was already on when I checked this Spring...the electrician probably turned it on to check his work. Sound logical or would the second start attempt in June properly warm the unit anyway?

    too much speculation.
    Many A/Cs are started without a 24 hour warm up with no adverse effects.

    How many times must one fix something before it is fixed?

    you have to admit it's creative thinking for a novice........I think based on what I'm hearing we will run as is. See how things go through next spring before the warranty truly evaporates and hope for the best from there. My next task is to sell the other half....you guys know how fun that can be! Thanks for all the information and advice.

    My opinion is if I pull up to a job and I have to add a booster with the unit still under warranty I will replace it and the supplier we use ask little to no questions.However the units we deal with all have scroll compressors in them.

    Theory is a booster should never have to be added to a scroll only recip.
    If I am wrong someone please correct me.

    Some units with a scroll, come from the factory with one.

    Some scrolls come from the factory with a start kit.

    4 and 5 ton scrolls take a lot to get off LRA, a start kit helps, and can extend their life span also.

    I stand corrected.I have just never seen them with boosters.I have put them on scrolls before to get someone by so I know it works.

    Creative; yes. But you are reminding me way too much of my wife who will just continue to ask question after question until I yell at her; OK! I don't know.....OK? Then she sulks and I feel bad

    Just because start components are needed is not an indication that something is wrong with the compressor. Applicable conditions are usually the reason for the need for start components. General low voltage, brown outs, voltage spikes, ground lightning or just normal wear of the compressor are common reasons for using start components.

    I understand all that you said but at a school I went to had a copeland technical advisor there and he told us never to put a booster on a scroll but apparently I was mislead or something changed.Maybe it was being lazy on my part for not doing research on it.Now I will.Thanks
