Re: buying a hydronics business

What does this "business" include? Does he have a lengthy clientele list or service contracts that come with it? Trucks? Inventory? Property? Tools? Without a name/reputation and clientele, a business is generally worth about 80% of real property value (tools, vehicles, inventory, equipment, etc). I run an upper 6 figure hydronics business but if I sold out tomorrow, it'd be worth $50k at most and that's only because of the aforementioned real property. The name isn't worth a dime if somebody else is at the helm, and there are no service contracts or guaranteed income to sell.

Re: compressor

Resistance of the windings is different than megging the windings.

Winding resistance is taken with a multimeter (or ohmmeter) set to resistance/ohms/Ω (if not autoranging then generally the lowest range). Should be less than 40 Ω between the run terminal ("R") and common ("C"). It will be different between start ("S") and common, but I can never remember if it's a little higher or a little lower. The measurement between R & S is ≈ the sum of the measurement between R & C and S & C.

'Megging' a compressor is measuring the resistance of the insulation of the motor. It's taken with a megohmmeter between any one compressor terminal (doesn't matter which) and ground. With a cold compressor, it may be as low as 20 MΩ but may creep up as you measure. A regular multimeter isn't a good choice for this measurement. While it can tell you if the windings are good and shorted, it can't tell you if there's a weak spot that's getting ready to blow through.
