How to Install a Hard Start Kit in Your Air Conditioner

Does your air conditioner need a hard start kit? If you need some help with it, in this video I show you how to install and wire a SPP6 Hard Start Kit. Here are some of the reasons why you might need to put one in:
- Your AC unit is getting old
- Occasionally trips breaker
- Long refrigerant line sets
- You have multiple air conditioners
- You have a non-bleed TXV metering device
- The compressor is locked up and changing the capacitor didn't help
- If you have a home power generator
- If you have known voltage fluctuation issues
- Lights dim when the air conditioner turns on

Back in the day, almost all AC units had a start capacitor. It does prolong the life of the unit but it will work with just a run capacitor (the silver one) so they decided to cut the "extra part" out. Just like cellphones used to have EMF blockers but since they were expensive, manufacturers decided to cut costs and stop putting them in. 🔋 And here are more capacitor videos for further information if needed: Original Video on Replacing a Capacitor: kzbin.info/www/bejne/eWmVeamYq7Vjbqc How to Replace a Capacitor Full Guide: kzbin.info/www/bejne/b4uql6l5YrWAjbc How to Order The CORRECT Capacitor: kzbin.info/www/bejne/o5zUkoKcq61nl5Y How to Check Capacitor With Multimeter: kzbin.info/www/bejne/a5CTn36jbpljpKM How to Replace a Start Capacitor: kzbin.info/www/bejne/nnSTn3mKZr2Dmas How to Discharge a Capacitor: kzbin.info/www/bejne/ambSi4ukeNGAepI How to Combine Capacitors: kzbin.info/www/bejne/p32tgIqLaJiHfNE What to do if Capacitor is Rusted: kzbin.info/www/bejne/iISsmmdtqt90pqs How to Install SPP6 Hard Start Kit: kzbin.info/www/bejne/ipmlpIV8p8mBn7s How to Install 5-2-1 Hard Start Kit: kzbin.info/www/bejne/gYO0ZHWwf7WDpJI How to Wire A/C Condenser Unit: kzbin.info/www/bejne/gXTEn417qLGJe6s

[@Yeps31]

Probably HVAC guys who watch it and get pissed that they will lose some easy jobs. I just ordered a replacement on ebay for $30 (including shipping). HVAC guy would charge $125+/hour and another 80-90 for the part.

I agree, that dude is a awesome teacher.

[@travislemarr9900]

Not this ac guy. More power to you. Theres no shortage of work. And just to add a reminder he said to make sure thers no coil behind the screw. 100 percent the number 2 thing i see with do it yourselfers. -Charge in the ozone-. Number 2 would be a 30 amp fuse for a 3 amp low voltage, now at the minimum you got a shorted wire in the outdoor unit and a fried transformer. At minimum

[@imyouragent]

I can't believe I was quoted over $700 to do install a hard start kit. Item cost me less than $15 on amazon and took less than 5 minutes to install. Thank you!

[@crayh5o]

My HVAC company installed one when they tested my run capacitor and it was close to dying during my Spring checkup. I don’t know if I really needed a hard start capacitor, but had them install it based on their suggestion and because the compressor was 14 years old. I don’t really notice a difference after it was installed, but I hope it can extend the life of the compressor. Thank you for making this video.

[@MrPLC999]

I finally got around to installing a KickStart unit. What a difference!! Should have done it years ago!! The compressor always made a very loud 60 cycle hum when it would start but in recent years it was occasionally cutting in and out when trying to start (it's a scroll). Now, the loud hum is gone, and no more cutting in and out. Perfect! I used the Rectorseal KS1 96506, by the way. Installation was easy.

[@lizbethpadilla777]

Would your ac use more electricity when it would do that? Because mine is doing that rn and I can’t find the start kit anywhere and my house is burning hot just wondering if I can have it on?

[@jsurprenant50]

The two wire hard start you have in your hand has a positive temperature coefficient thermistor under that top cap. Not a potential relay. It opens and closes due to temperature rise and fall, not an electromagnet

[@WordofAdviceTV]

Thank you for the correction! Good to know!

So hypothetically if one has this on their AC Unit and they live in say the DESERT, where daytime temps are 100+, this is worse than having nothing? correct?

It actually changes the phase angle during start up, which increases start up torque. The relay will drop out once the run winding gets up to speed.

Thx. I am the proud owner of (2) 33 year old Trane condenser units - installed when the house was built. Last night the upstairs unit stopped cooling. I replaced the 3 capacitors (2 had bad readings) from my stash and got the unit running. I had heard about these Hard Start boost devices but needed to know more. This video is great. Many thanks. My situation checks several on that list. I will order one today.

@@lklpalka Hi Ed. Sorry about the slow response. Yes, this booster and my A.C. unit are working fine. I expect to get another season out of the 2 A.C. units ... fingers crossed considering their age. If you are still undecided about buying and installing one, my recommendation still holds true.

@@ApexHotShot I'm ready to install the replacement hard start kit today... same specs as original. Have a spare cap with extra 100mfd more kick on hand just in case. Repl. of oem dual-run cap didn't do much. Maybe new contactor and start kit will keep it for another year or two.

[@edvanhalen9056]

Love your videos! Very informative. Open Question for the HVAC Gurus... I know Start performance improvement with a 5-2-1 Hard Start Capacitor Kit is not as great on SCROLL compressors, compared to RECIPROCAL types (many Y.T. vids show reductions of Inrush Amps by as much as 45% after installing a 5-2-1 Kit - I assume these are on Reciprocal compressor units). At best, I've seen only about a 9% reduction in Inrush Amps on my Rheem 5-Ton Scroll Compressor aftter the 5-2-1 Kit was installed. Is this a normal "improvement" to see when matching the 5-2-1 Hard Start kit (biggest capacitor) to a Scroll compressor, or should I be seeing lower Inrush results than this? Install Story/DETAILS, for anyone interested: So, I just installed a CPS 5-2-1 CSRU3 Hard Start KIT in my 7YR old Rheem 5-ton SCROLL compressor/condenser unit, ( was running fine), but was slightly slower, buzzier, and metered with INRUSH Amps a bit above the specification on start-ups, recently. L.R.A. specification for this 5-Ton split unit is: 152.9 Amps. BEFORE 5-2-1 Install... Compressor "C" wire Metered INRUSH = 157.2 Amps. AFTER 5-2-1 Install... Compressor "C" wire Metered INRUSH = 156.1 Amps. Metered several "call for cooling" startups @ 150-155Amps INRUSH, AFTER Install: Best score was 147Amps INRUSH, with most starts hitting 152-155Amps. Disappointed (thinking the 5-2-1 kit was a dud), I metered INRUSH again, a day later, on a few more start-ups - I found that my INRUSH was averaging between 142-146 Amps and the compressor has a more positive start, no buzzy wind-up; lighting in home doesn't dim during start, as before. All wiring terminals checked & re-verified, good. (Same weather, thermostat settings, no other system changes since install day). Odd - I'm unsure why unit seemed to perform better the following day. Thanks for reading!

[@jmonte2811]

Great simple and straight forward. I have tired the 5 2 1 on a couple of units without much success only lasting a few months (following the wiring diagram carefully). So I am going to give this one a try. Thanks again.

Installing dishwasher, fixing plumbing issues, installing 240v circuit, adding new breakers in the electrical panel, troubleshooting AC problems, installing thermostat, installing inlet for generator, etc, etc, etc. My advice: if you feel that you can do it, then you are right.

Awesome explanation. My run capacitor is open circuit. Now that I know it is a run capacitor thanks to you, I can just replace it. I was looking for the start kit in my unit and didn't see one, even though it's shown in the schematic. Sounds like I could easily add it and improve things a bit.

[@peterh2800]

Excellent teacher. Excellent video.

[@Anthony-kf1ec]

So if I already have a capacitor installed, should I take that out before installing my hard start kit?

[@Capt-Intrepid]

This Subco uses a Positive Temperature Coefficient Relay (as stated on their website) not a Potential Relay. Not Good! Only use Hard Start Kits that use a true Potential Relay. The RectorSeal Kickstart (2 wire) and the 5-2-1 Compressor Saver (3 wire) hard start kits use a Potential Relay. I recommend the Kickstart (it uses 2 wires that connect to the Run Capacitor - HERM and COM). But the Compressor Saver is also good (3 wires with one connecting to the common / ground on the Contactor relay). They both work the same way - the Potential Relay detects the pickup voltage (back EMF). This causes the relay to disconnect the start capacitor when the compressor reaches about 75% speed (usually less than a second). Note: Supco does have hard start kits with a Mechanical Potential Relay (Models 3W1, 3W2, & 3W3).

FYI those subco caps are not good! Love the channel!

Hi Jay I have a new installed an AC unit the inside and the out side about a year ago. However, a few days ago the condenser unit capacitor failed and unable to start the compressor . I had to replace the capacitor, now working fine. The unit is 3 tone /14 seer and 45/5 capacitor. I also noticed that it doesn’t have hard start capacitor; my question is would it helps to put hard start capacitor to maintain the life of compressor and for easy start. I always watch your video. I exceedingly appreciate you for every education you provided us with. Thank you

[@logangregory7105]

Only thing I’d add is do the wires matter or can you use the two interchangeable

[@elbrad1016]

Great video brother, I wish you were my instructor.

[@DanhNguyen-sf8zo]

Thank you Jay, you're the Best HVAC Instructor Dan HVAC ATL 👍

[@johnson4940]

Thank you man.

[@wasimedoo7994]

Very good information very easy to install

[@mikeinocencio9516]

If you already have a start assist and a relay like he did on your unit. Make sure you take that out of the circuit befor installing a hardstart kit..

[@robertpaulson8094]

The part you missed in your explanation. Do I still hook just the 2 wires up and leave the relay connected? Mine is an older trane that has the capacitor hooked up to the relay with 3 wires RLY1097 relay

[@MegaGuitman]

Thank you for this awesome video sure helped getting my ac up and running

[@edwinblanco2675]

You made look easier bro your the men

[@mariovasquez4727]

Very precise straight to the point

[@DanO181919]

I’m just trying to understand in my head how this works....lol Compressors are very specific about what size capacitors is will use. How is it that that the 3 in 1 Supco hard start kit will work for multiple different units that require different size caps to run the compressor. It’s like a one size fits all.

[@benjamindees]

It's really only the run capacitor that needs to be a specific size. The start capacitor just needs to be 'big enough'. So once it is started, the start capacitor is taken out of the circuit by a relay.

[@michaelsabatiii6052]

something like that would be great for air comp.

[@JoelRemix]

I read that a hard start kit must match your system’s tonnage and or compressor HP. So how do we choose the correct hard start kit for our system? Thank you 😊

[@jasonpoolo3523]

There's a 1,2,3 ton start up and a4, 5 ton startup. Look on your a/c what tonnage it is and choose one or the other. If you live where it's hot get a 3wire kit not a two wire kit.

[@jasonpoolo3523]

Sorry just saw how old your comment was

[@JoelRemix]

@@jasonpoolo3523 and still helpful to know this. Thank you for taking the time to share. I live in Texas and the three wire thing was also good to know.

update on safety of possible electric charge on capacitor and disconnecting power to unit

[@moisesbonilla9362]

Thank you sir for taking your time and posting your helping videos, ordered my subco hard start today

[@WordofAdviceTV]

Glad I could help! Thank you for leaving a comment!

[@SRT8FLEX]

Thank you!

[@luiscayey777]

I like this videos from him, they are very educational

[@joebojanic1905]

Thanks for the info. Our compressor was giving me some issues this year so I tried this and it worked. Hopefully we can at least get through this summer with this cheap fix.

[@WordofAdviceTV]

Might even get a couple years out of it! :) Stay cool, thank you for commenting!

[@wasimedoo1506]

That was very good information thanks for that so I will have to take out the start capacitor and just install this hard start on com and herm

[@lisarod4615]

Great video for beginners. Thanks!

[@tntheatingandairllc]

Great video very helpful keep up the good work 👍👍

[@paulbrunton3116]

You are awesome Saved me a bunch! Thank you!

[@erock801]

Will be ordering. Our Rheem system is 15+ years old but with a newer Copeland compressor and I just replaced the reeeaaaaally bad contactor and cap. you mentioned lights dimming - do you have a video for how to trouble shoot? it seems like our lights dim every time something turns on!

[@mannymixxx]

Can you do a video on how to install 521 hard start with heat sequencer. This is supposed to be the best setup as hard stop kit will provide the boost needed to start the compressor thus reducing amp load which is will be good on you electric bill. And the hest sequencer will allow the condenser fan to start first to free up the refringent and the compressor few seconds later so that the compressor doesnt need to work too hard to get the refringent moving. This also reduces the noise level drasticaly. It's like having a hign end high efficiency unit that runs quite!!!!

[@kennywhitmire]

Excellent and very explanatory video! I have a question, I have a 2 ton compressor, and a 50amp generator with a 15000 (12500 constant) watts , it has a hard time with the start up , I am ordering one of your hard starts and curious of your thoughts if this could help my issue?

[@thinkingimpaired5663]

Interesting video as i sit in my house with a broken hvac system. Lol

[@djimenez1877]

Where are you located?

[@thinkingimpaired5663]

@@djimenez1877 thanks for asking i went ahead and completed the repair. Im in northern california. Ive had so many no shows from repair companies that i just ended up doing the repair myself. One electricians repair was so shoddy that i actually had two fires from shorts. I repaired those myself because of no shows one again.

[@brandonrolland8240]

You're the goat, thank you!

[@MrLuiscbr]

Can you make a video on how to install a circuit board, on a furnace or Airhundler that doesn't use a board.

[@condor5635]

So I have a dual capacitor just like you showed. Will any hard start kit work regardless of the microfarads your capacitor is rated at? They don’t have any specifications like the capacitors with microfarads or anything? Great video thanks for posting
