I’m a retired school district Facilities Manager. Our district had thousand of A/C units in the desert. Our maintenance department faced 20 to 30 units down on any given 110 degree day. Many units were 20 or more years old due to budget restraints. Hard start kits are not a panacea, but when you have 30 kids and a teacher in a sweltering room, they serve a purpose until the compressor can be replaced (not an option with RV’s)

They tried just about every “hard start” kit on the market and the one that was most successful was the 5-2-1 compressor saver.

I put one on my 13.5 and it has never failed to start and restart with my Yammy 2400 at high altitude (up to 7,500) and high temperature.

Jus’ sayin’

Thinking of the "replace compressor" point made above, an appliance tech told me that compressor windings develop additional resistance with age, therefore draw more amps, therefore harder to start, therefore even damaging a start device. So a "boost" like 5-2-1 can allow a tired compressor to work a little longer. Maybe a lot longer. I put a SUPCO kit on a Whirlpool fridge 10 years ago. It had "eaten" the original start assist and that cheap fix has had it running ever since.

They are just capacitors. Nothing else. Installed correctly, I don't think they can void your warranty. But, that's easy for me to say. It's not my warranty. For only about ten times the Coleman kit price, you can get a MicroAir Easy Start kit (Web Site). It really does a better job at controlling start-up timing and spreading the surge. But, it is pricey. I put one in my trailer. I'm very satisfied.


Bingo...I installed two of these on my 5th. I can run both a/c's at same time on 30A circuit now.

I hear good things about 5-2-1 Compressor Saver as well. It connects with at least one additional wire than SUPCO, which might make it able to determine the startup status of the compressor a little more accurately.

My AC installer included a 5-2-1 on my 4 ton home unit when I replaced the unit a few years ago. Only time will tell if the compressor last longer than the previous one.
