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

If you are wondering why don't all AC condenser units have hard start kits or start capacitors, it's simply because manufacturers decided to cut costs. 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.

I can't believe how many videos this dude makes that I've used. Thank you so much

[Mr.Average]

Dude... I ordered hard start kits for my 3 HVAC units, but I was not going to install them until I saw you do it! Again, much thanks and kudos to you.

[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!

[highlandswebclass]

I don’t see how anyone could NOT like this video. He not only showed exactly how to do what he said he was going to do, but gave an extra ton of free useful information. Some people will never be satisfied. Anyway, thanks a ton! 😊 🙏🏽

[SGuirin]

You saved me a lot of money. It took me literally 3 minutes to install the hard start kit and the compressor started right away.

[YvonneCSalazar]

thank you!! We live in Dallas, TX and just paid $$$ (10 times mark up) to have an A/C repair man install this. Glad I decided to learn more about this. Being a homeowner is tough (and can be expensive) so you empower & educate us consumers.

[MikeJones-lnyj]

Thanks so much! Compressor kept causing a locked rotor. Installing this hard start kit has helped so far! You are great at explaining what has to be done and how.

[WilliamWBG]

My friend, you are 100% awesome for teaching us how to service our HVAC. I cannot thank you enough.

[samTollefson]

I have a 13, 500 btu portable a/c unit that wouldn't start when powering the house with a 5 kw generator, I installed this exact one and it ran perfect! That one and a small window unit in the bedroom got us through a 9 day power outage after a hurricane. now, after seeing this video, I will install my spare one on my house 3 ton unit and get another spare.
Thanks as always for a great video!

[POW]

I was outside and my AC start up like a maniac screaming...I am glad the hard start capacitor on this tutorial clip is easy to easy to follow! I can do it.

[bassman]

Love this young man....soooo much helpful information with all his YouTube videos....my winter home in Florida thanks you!! lol I've referenced you more times than I can recall!! Thank you so much👍👍👍👍👍👍

[duanehouston]

[EllenD]

You're awesome! I'm a stay at home mom with zero hvac experience, yet I was able to replace our ac unit's start capacitor and both run capacitors in less than 20 minutes all thanks to you!!!! Thank you!!!

[MrPLC]

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.

[jsurprenant]

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

[TheTechParty]

You are the man!!! That kind of simple information can change lives. It worked, and it was simple!!! Thank you!!!

[crayho]

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.
