    Most common capacitors to stock ?

    Hello,
    Im tired of paying for expensive universal capacitors to keep on truck.
    Can some of you guys with more experience recommend the most common size dual capacitors for residential condensing units to keep stocked on the truck ? It makes alot more sense to me to have these on the truck instead of making a trip to the parts supplier.
    thanks,
    Bob

    I would be embarrassed to tell you how many different caps I stock on my truck, but I usually never have to chase one, and if I do have to chase one, I buy two, so I will have that one in stock for the next time.

    Thanks Mr Bill,
    I assume you have 20 to 30 different caps on your truck

    For me... I just charge enough $$ for a cap to make the universals (Turbo's) pay.

    I generally keep around a dozen give or take fixed values on hand... then the variables.

    Remember you can 'gang up' fixed caps also.

    Depends on budget. There are alot of combinations. I try and replace what i use with two. Also keep singles in case i have to join two for certain applications. I hate to have a deep stock of anything that isnt being used.

    All of them.
    If more government is the answer, then it's a really stupid question.

    60

    And all the 25-60 are +5 mfd 440v

    Maybe a few randoms tossed in the mix.

    Then we keep alot of 25-50 in stock at the office with the +3 and +7.5 fan motor

    Last summer one of our techs filled a 5 gallon bucket full of capacitors out in one of our heat spells for one weekend. Once you get them all stocked. over time i would think the single use capacitors would be the best bang for your buck and $$

    I've got about 50-60 caps in my truck. I've never used the multi mfd ones. From 5mfd to 80/7.5 and everything in between.

    I keep a handful of 3,5,7.5,10,and 15. I stock up on the Turbo universals. The Universal caps are more expensive but they have a 5 year warranty and the customers love warranties.

    A couple of Turbo 200's ought to do the trick. Along with a few 5's and 7.5's for those pesky blower motors.
