Thx so much. Too many videos assume that you know what wire on the starter does what. Once you explained that either wire can go on the C or Herm connection, things made sense.

[@Angel-bs1hm]

Same here bro!

[@jonsebastian1366]

A tech. put this on my heat pump today because the compressor was having trouble starting. It was not tripping the breaker, though. The capacitor tested good, but he installed this anyway. It seems to work better so far. Another company came out 4 times before I asked for a second opinion and the new guy installed this booster.

[@michaelcostello6991]

Excellent video. Took me a moment to realise the hard start is in parallel with the compressor run capacitor. Thank you

[@acservicetechchannel]

Glad it helped

[@3kgtman]

You should do a video about the different kind of hard start kits available and what applications they are best for. Like the three wire or the ones with electric or mechanical potential relays

[@acservicetechchannel]

I would like to at some point, thanks Wayne S!

[@parker897]

Finally this was explained to the point that I was confident in hooking this up myself on my RV roof air. Thank You

[@acservicetechchannel]

Thanks

[@Angel-bs1hm]

Nice video and nice ring by the way.

[@dennisrhodes9970]

Very helpful!! Thanks

[@abousamah1967]

Nice explnation I confused about ptc relays This relay disconnected the circuit when it heated ok After disconnecting it will become cold why not connect again Thank u

[@tejonBiker]

Thanks for this, I make the service to a some type of frankenstein, for some reason the previous technician take out all the capacitors and potential relay and just wired this between R and S wire, I was not able to figure out what was this thing, for some reason the previous technician don't install the run capacitor and the compresor stopped in the middle of the cycle.

[@williamserver4332]

Great informative video

[@wasimedoo7994]

Bro does that hard start capicator have a size how do you know the right size thanks keep it up God bless

[@richardrussell1025]

Have an oem hard start but the cap is blown on it. Replace the cap or just go with one of these spp6.

[@jerrymontalbano3222]

There is no mention with the Hard Start Capacitor Kit and what to do with the relay (I have a Carrier HN51KC024 coil relay in the compressor box)? As the kit has an attached unit as part of the kit, do I keep in the relay connected as is placed currently? Also, when I purchase the kit, is it a universal one or do I have to purchase a specific type or specification which will work with my Run Capacitor?

[@stanleykania7184]

Thanks

[@bozolito108]

Thank you good sir

[@acservicetechchannel]

You're welcome

[@earthstewardude]

another video say's this Suppco "Super Boost" kit does not really have a relay but a thermistor. I prefer to use this Suppco " Supper Boost" kit as it's cheaper than the one with the separate relay for $40... How does a newbie like me know which one to use? I have a 15,000 btu window unit so I'm guessing the SPP6 is going to be better than the SPP5... Thanks for your great videos!

[@acservicetechchannel]

A larger start cap would only be used for larger systems so for a small system that is less than 2 tons 24,000 btu/hr go ahead and use the SPP5, thanks

[@richieschmidt6225]

Is there any reason to not put the most powerful hard start capacitor on even a brand new system? So cheap, so easy to install, what's the catch?

[@ps-gr7pi]

hi. im hvac student now. im enjoying watching your video. i have couple of question. 1. are hard start kit and start capacitor same things? 2. most of unit have run capacitor. but the start wire from comp and condenser fan connect to run capacitor. i dont understand why start wire from comp and condenser fan have to wire run capacitor. i feel run wires have to connect to run capacitor. 3. then when do we use potential relay instead of hard start kit. i really appreciate your work. thanks a lot!!

[@acservicetechchannel]

A start capacitor does not have a potential relay, current relay, or ptc to open the electrical circuit after the motor is powered. A hard start kit from a equipment manufacturer is equipped with a potential relay to open the circuit up and shut the start cap out of the circuit. The Superboost in the video had 2 ptc's on the top of the cap which take the start cap out of the circuit, thanks. Start caps is connected onto the start winding of the on the dual cap. They connect to the herm and the other lead may connect to the 120v leg on the c terminal of the run cap or the contactor. The kick out of the circuit after the motor has started.

[@ps-gr7pi]

thank you so much! i am learning a lot with your channel!!!

[@dtrrtd774]

So the hard start kits are basically larger capacitors that allow for greater starting torque, but have some method of automatically disconnecting them once it's up to speed, because they can't be left in place continuously without overheating. Maybe OEM setups don't use them by default to avoid possible issues if the disconnect mechanism fails, which could end up overheating and damaging the compressor itself. Otherwise the only drawback may be just a few bucks extra cost, which may be more the driving factor for them.

[@acservicetechchannel]

Thanks Keith, I appreciate it. Will do!

[@haroldnesbitt9126]

Hello, I have a 2 ton unit and the compressor barely comes on, and then goes off, I think it is stuck! I saw below that you said "Basically, we don't add them (5-2-1 Hard Start) unless the motor is having a problem starting." My compressor IS having trouble starting. Would you suggest the 5-2-1 hard start units or would the SPP5 or 6 work? My fan blows, and sometimes if I listen close enough I can hear the compressor with a quiet buzz, in and out. The temp maintains until it gets hot, then goes from 75 to 78; the pipes outside show condensation, but I can hear clearly that the compressor is not on. The upstairs unit sits right next to it, and I hear the compressor working just fine. Would a hard start work?

[@jimbola77]

super video thank's for sharing!!!

[@itcoinbaythebitcoinmarketp5296]

Hi I was wondering if you might have any guesses for my situation which is: Sometime within the last several years the guys servicing my system added a hard start capacitor (if they told me about this I have forgotten). Anyway, when we first turned the AC on this year it tripped the breaker. However, after resetting the breaker it ran fine but again trips the breaker at seemingly random intervals. Perhaps heat of day, sometimes once, sometimes twice, causes this? I did find a fairly plugged intake filter downstairs (since we don't turn on the air downstairs I mistakenly thought that air was not being drawn in there) which I replaced and that seemed to alleviate the issue for about a week. Then it started doing the same thing again, once or twice a day, usually in the afternoon it trips the breaker but will reset and run fine. Yesterday we replaced the run capacitor (which subsequently checked out within tolerance) but shortly afterward it tripped the breaker again but also again it reset and has been running fine. An AC guy told me to get ready to replace the unit/compressor as it's R22. The system is 15+/- years old. Sounds like the only thing left to check is the voltage to the compressor but that is probably grasping at straws. Any other suggestions? Thanks in advance for any help. Great videos, thanks!!!

[@michaelbrandon5385]

What ended up happening my breaker has been tripping... I just had the capacitor replaced with a. Hard start kit.... we will see if it does the trick over the next few days as where I live gets very very hot.

[@itcoinbaythebitcoinmarketp5296]

Broke down and bought a new unit. One thing the company warned me about is double filtering which puts extra strain on the system--since I have a filter at the unit they told me not to filter at the return air intakes. Thought I'd mention this in case this led to a premature death of my compressor and might prevent it for someone else.

[@SombraLocs]

Great video!

[@demoll78]

Can't I use that to run 14seer 3 ton ac unit with that off a generator

[@keithhoward3181]

Good video. Keep them coming

[@acservicetechchannel]

Thank you very much!

[@earthstewardude]

I have a 15,000 BTU window unit where compressor is struggling / on briefly and then off... no mention in your title that you are only talking about central air. Is this solution valid for a big 15,000 window unit?

[@acservicetechchannel]

It helps for starting the compressor but doesn't help while the compressor is running, thanks

[@douglasmccoy2571]

What if the cap only has two slots....one with 2 knives and one with 4 knives? Do you do it the same way? Or do you put the double ended to the supply and one to the 2 knife or 4 knife?

[@acservicetechchannel]

Hey Douglas, check out these videos first on capacitors, testing, and wiring, thanks- kzbin.info/www/bejne/hZO3oZyuh7ytr7M

[@ProfessorBalance]

Could you show us the size of the actual boost capacitor inside?

[@acservicetechchannel]

The ratings on these capacitors are actually covered by the sticker on the side, thanks

[@truckinforever985]

How do you determine the horsepower for the correct Supco

[@ralphhalili8511]

If you have a current or potential relay and start and run cap all checked out good. Do you add and wire that hard start one lead to c and one lead to h of the dual run cap or you have to take out the oem start cap and current ot potentially relay? Thanks

[@acservicetechchannel]

What is the initial problem. Is the compressor not starting?

[@LocalAutosOnline]

What do I do if my capacitor already has 4 common wires connected? I am trying to add a Hard Start kit to my pool heater and I don't have a common terminal available on the capacitor. Thanks in advance

[@acservicetechchannel]

There should be a common wire coming from the contactor to the capacitor. At least that is what we have on air conditioning units. We just add it at the contactor since they are connected by a 3" long wire and there are more tabs there.

[@LocalAutosOnline]

@@acservicetechchannel Thanks, I was thinking along the same lines but wanted to be 100% sure. I wired it to the contactor and it works perfectly. Thanks again.

[@1condo1]

Just what I needed to know! Thanks.

[@acservicetechchannel]

Thanks 1condo1!

[@johntrauger68]

Is it wise to install a hard start kit (I've got the 5-2-1 kit I think it is called), and a scroll compressor on my home unit. I've read the kit will significantly reduce the motor starting current which from an old motor guy like me is a good thing. I had an HVAC service tech tell me I should not add the kit unless I need it, because of mechanical blah, blah issues. What little I know about scroll compressors informs me they have a minimal or no valve train. How might the startup mechanical be impacted by lower motor starting current and a bit more starting torque? Thanks for any input.

[@acservicetechchannel]

Basically, we don't add them unless the motor is having a problem starting. It would be bad to potentially weaken and overheat the thermal overload limit on a scroll as it is glued with resin in place on top of the windings inside the compressor. He was probably just saying anything added after OEM could be a concern for the manufacturer in a warranty issue, that is all. The start cap takes itself out within a fraction of a second due to the ptc thermister, thanks

[@johntrauger68]

Thanks.

[@acservicetechchannel]

Glad to help John!

[@markphillipsart]

Since there isn't much price difference between the SPP5 and SPP6 why not just go with the SPP6 first? Just wondering.

[@acservicetechchannel]

We try not to oversize the start cap in order to make sure that there is not too much voltage going to the compressor, that is all. Thanks

[@markphillipsart]

Thank you for the response.

[@DanO181919]

Is there a way to test a hard start kit itself to determine that it is working? Thanks!

[@acservicetechchannel]

mfd of the cap itself and 0 resistance across the two ptc relays inside. The ptcs are already connected and you can measure through them but the mfd of the cap is covered by the sticker on the side, thanks Danny L!

[@dtrrtd774]

@@acservicetechchannel Maybe check that the PTC component is working by passing current through it to see that it starts increasing in resistance as it heats up as a final check too.

[@phillyflash43]

I replaced a faulty relay switch with an RCO810 Supco 3 'N 1 Start device. I used it to replace a defective relay switch (clicks once per minute, rattles inside). It instructs the user to remove any capacitor (my fridge didn't have one) and overload switch (my fridge had a "guardette" mounted against the compressor). So I removed the guardette, and wired in the RCO810 per instructions. I'm wondering though if I should have removed the guardette from the circuit since I suspect it's some kind of thermal protection device or maybe I should wire it back in? The fridge is working but I'm concerned I may have removed a vital component.

[@acservicetechchannel]

Honestly, I would replace exact model number with exact model number if you are not sure and that is it, thanks

[@phillyflash43]

Unfortunately the original part is no longer available anywhere, even parts websites. The refrigerator is working ok so far. I've contacted supco for advice, they've helped in the past. Thank you for responding.

[@HowToDoitright]

Is it really beneficial to install this on every AC unit which is working just fine? I have heard mixed inputs. Some say it help reduce start stress on compressors and some say it put load on compressors with hard start? So confusing. I have done some research and it does reduce the Inrush Amperage however not sure if it elongates the compressor life or shortens it?

[@acservicetechchannel]

I can only go by manufacturers and they typically say to only install their hard start kits for compressor life but yeah a start cap with a potential relay or ptc thermistor does reduce inrush, thanks!

[@sk-kx2um]

the breaker.was jumping The kit he said didnt know how long it last. The SEER is 27 and mines was reading at 33, so he says it was jumping back off cause it went past 27. He said he had a starter kt, gave me cool air but cause the valves were barely hanging, he couldnt tell me how long it stay cool, Anyone?

[@MsFishingdog]

great video. thanks

[@acservicetechchannel]

Thank you for your comments!

[@10rninjariderzx]

those 2 wire bopst caps with ptc are junk . put a potential relay and proper start cap with bleed resistor.
