Air Conditioner Soft Start Module, Easy DIY Install, Smallest Soft Start on The Market, Reverse Motor Protection for Generator Use. Proven Reliability. (16-32A)

As another commenter has said with great detail (Lindguini} this device works great. My inrush went from 80amp to under 30. I have an inverter with batteries and solar panels - and I was counting on being able to power my heatpump with this new setup. It would - barely - but the Vout from the inverter would drop from 240V to 160V - which is well below what the specs say is acceptable for my heatpump (197V). On my Goodman HP the "contactor" in built into a control board - not a separate relay like all of the examples. But I emailed a picture of my wiring diagram to their support email - and within an hour "Bob" (I suspect that email address is a shared one but who knows) sends me a diagram of a very similar Goodman control board - with the connections I needed to make. Only 4 were needed in my case. I'm pretty good on these DIY projects but I admit I was very nervous when I applied power the first time - the Airgo I received seemed like a possible return - but no issues. It did also seemed noticeably quieter. Anyway - inrush went from 80 to mid to upper 20s amps - and the voltage drop from the inverter during that inrush interval improved from 160 to 220. Very happy with this product. If you have any questions about how to connect take a picture of your wiring diagram - it should be on the inside of the access cover on your HP - and send it to "Bob". Don't guess. If you are not comfortable around hi voltage than hire a HVAC tech to put it in. I ask my installer if he could assign a tech to assist - at his normal "time and material" rates - and he did not to get involved - that it was VERY unlikely Goodman would approve of this modification - which I agreed was very likely - and my sense was that he did not want to get involved if equipment went bad - either during or after this "modification". I probably would have done the same. Just be aware.

I purchased this unit to take one of my AC units off grid with my Solar system. The 5T unit had a 7Kw startup that kicked my inverter back to the grid. This soft starter did exactly what I needed. AC now starts up at 4Kw and is stable. I can't wait to see what this does to my electric bill, in the heat of summer and off grid. I decided to start this project on a Saturday and quickly had a confidence issue when I wasn't 100% on the compressor load wire. Off course this is a must be 100% accurate wiring, no room for error or something gets cooked $$$. Called the number on the directions, did not expect to reach anyone. Just as I was taking pics to email support on Monday, Bob calls. I text him the pics and he walked me through everything and explained each wire and what I had. He even explained the Lennox factory wire diagram I sent him. With 110% confidence now, it worked great! My son is going to buy one now...

This soft start device is a game changer. We have a Goodman 5-ton condenser that starts each time with a loud, but normal, "thump" as the compressor gets hit with 130A start-up current. Residential condensers work this way by design since it requires the least amount of parts (simple contactor and run capacitor) and is therefore cheaper to manufacture. All of this is fine if your AC unit is located far enough away from your living space that the start up noise is not bothersome.Unfortunately, like most homes, our AC unit is installed on the side of our 3,000 sq. ft. house and you can hear the condenser start from most rooms. A good amount of the start up noise is amplified by the refrigerant lines that enter the house, go up the wall, and then over the attic space to the furnace/AC unit in the middle of the house. I have tried condenser mounting pads on the slab and an additional support bracket for the large refrigerant line but nothing has reduced the reverberating "thump" noise at start up.My research into this issue showed that people generally try to solve one of two problems with their AC units: "not enough" start problems and "too much" start problems. The "not enough" start camp winds up installing hard start capacitors to give the compressor an extra jolt so that it starts up reliably. This can be useful for older compressors or for units where the owner hasn't diagnosed other faults such as a worn out start/run capacitor. The other camp searches for ways to reduce the "too much" start problem that causes high current draw (a problem for generator/solar power sources), noise, and wear-and-tear on the compressor that I mentioned earlier.Which brings us to the electronic soft starter. This device is specifically designed to control the compressor in-rush current at start up and thereby reduce high power inrush, unnecessary noise, and wear on the compressor motor. It gradually accelerates the motor up to speed instead of hitting it with full current all at once. It's like accelerating in your car by gradually pressing the accelerator as opposed to slamming down the pedal and going full throttle from every stop. Both get you where you want to go but only one method does so without unnecessary power consumption, noise, and wear-and-tear.Installation of the AIRGO device is very straightforward for the technically-inclined and for those familiar with AC condenser components. The kit includes all the additional wires you need with pre-crimped terminations that makes installation in a standard AC unit easy. It turns out that the AIRGO unit is identical to the Eltwin soft starter (also sold here) but has different branding and, frankly, a much easier to understand connection diagram. I did create my own connection diagram (see photos) so that I could fully understand the connections as they related to my system (I also replaced the contactor and run capacitor at the same time). NOTE REGARDING WIRING: It doesn't matter if you have a single pole or double pole contactor. You can use either type per AIRGO with no wiring differences whatsoever. I did find (on Eltwin's soft starter website, btw) a schematic showing the soft starter "ACTIVE (T)" wire connected to the switching pole of the single pole contactor and the "COMMON" wire connected to the pass-through pole. Again, it makes no difference which pole is used but I wired it per the Eltwin schematic anyway. This is shown in the photo attached.Once connected, everything worked perfectly and exceeded my modest expectations. The AIRGO soft starter has COMPLETELY ELIMINATED THE START-UP "THUMP" NOISE from the compressor. It's totally gone. When standing next to the condenser, the ONLY start up sounds are the simple click of the contactor and then a slow whooshing sound as the compressor and fan come up to speed in less than 2 seconds. Inside the house, the only way we know that the condenser has turned on is when the interior HVAC fan powers up. No more jolt, no more “thump” —completely gone.In summary, the AIRGO soft starter delivers everything it promises and is worth every penny to restore peace and quiet to your AC condenser start-up. The AIRGO (aka Eltwin) soft starter device appears to have been around for at least 10 years which speaks well of its ongoing value and overall reliability. I expect the device has been refined to the point that it will deliver years of service when properly sized for your system and installed correctly. I only wish I had discovered this device years ago! Oh well, if you install one, you'll quickly forget the few extra dollars you spent on this quality device. For me, it paid for itself on the first start up.Thank you, AIRGO!

With hurricane season coming, I want to make sure that our home generator can keep the AC going in case of power outage. Our hard start kit wasn’t working under Generator power. While I was eyeing more expensive soft start kits (500$), I went with this one because I don’t think I really need the monitoring features and it was cheaper.Well, cheaper does not equal worse. This product is great. It works just as advertised but more than that , the customer service is simply outstanding. I called and left a message with a question about a contractor and the owner of the company. (The guy in the YouTube video.) called me back within 10 minutes. He explained he had been on the phone all day handling customer concerns. He spoke perfect America English. He was very patient with me. I sent him pictures of what I had done and he spent the time explaining everything to me and help me wire it correctly. In this day and age that level of Customer Care is unheard of. I don’t know how he’s gonna manage to do it if he continues to have as much success. Anyway, I highly recommend this to anyone get it now before he gets too big to handle all the phone calls.
