DIY install of air conditioner soft-start (Micro-Air Easy Start Flex) - so much quieter!

[@adammorton9311]

I have watched several of these micro air install videos as I plan to install the same flex this week. With that, I have to say you made a fantastic video and I appreciate the effort involved. I laughed out loud at the blackout after the install.

[@PaulBailey3]

I installed an older version on my home AC and my RV. They are wonderful devices. I can't believe this is not built into AC units already.

[@thepiecesfit5049]

Think I'm going to go steal the Hutch Mountain wiring approach. Blue female spade disconnects for orange and black, then Wago 221 splicing connectors for the white and brown wires. This way you can splice into the existing wires leaving the original connection, and should the Micro-Air fail you can have a running AC again in relatively short order without having to redo the termination on the wires.

[@harveypaxton1232]

Thanks for the great video. If your lights were flickering you should start from the breaker in the panel. Pull the breaker and check the buss bar and the breaker where it snaps onto the buss bar. then make sure the wires are properly torqued. Then the disconnect at the condenser and finally the connections in the condenser. They all seem to loosen over time. The Soft Start is a great way to make your unit last longer.

To add to the discussion. I bought a MicroAir soft starter. Had the company confirm that is was sized correctly and they even verified the connections - run wire, etc. Worked great for 2 months. Then no cold air. House in Florida, in the summer, heating up to 85+. I was out of town, so called my local AC tech and he discovered the run wire connection from the soft start was burned. For a distance of over 6 inches. He rewired the AC and Voila cold air again. I contacted MicroAir and told them what happened. Me being a trusting consumer, I thought they would stand by their product. NOPE! They told me the failure was caused by the heat. You think? Florida, in the summer, DUH! The original run wire worked for 9 years and after reconnecting the AC works fine. There is something wrong with the soft started and they won't admit it or support their unit. BUYER BEWARE!!

[@ZimorKilled]

Excellent video. Thanks for providing. Helped me to install quickly. I completed the install this past weekend on both my 3 ton and 2 ton units. I received 65% reduction on inrush, and minimal amps reduction on running. Given the cost of these units and cost for electricity, in Houston, I will never receive a payback. But, I installed these units so I could run my generator and start both AC units, which I couldn't beforehand. Maybe I could extend the life of my units by 1 year, but, that is an unknown.

[@ZimorKilled]

@@RadioRich100 I measured current both from my meter and as-noted on the Bluetooth app supplied by Micro-Air. Although not exactly the same amp reading, it was close. Soft starters for AC units provide a "ramp-up in voltage" that enables lower amperage and less heat, and wear and tear, on the fan and compressor motor. I am a registered Mechanical Engineer in the state of Texas.

[@ZimorKilled]

@@RadioRich100 Well geez ... I couldn't start my 3 Ton unit with the generator powering my house, before installing the soft starters, now I power both my AC units with spare amps to run microwave and other smaller appliances. This was confirmed when Beryl came through. But, have it your way ... I will keep my soft starters.

[@ZimorKilled]

@@RadioRich100 I have a Generac 24kw unit. Measured load, without AC + normal household operation is (refrig, etc.) measured at 22 amps (measured by the gen installer). The 24kw has a max load amperage of about 90. LRA for the 3 ton is 91 amps, and 2 ton is 67 amp. Obviously, I can start the 2 ton without the soft starter but 3 ton just trips on in-rush overload - this was proven at commissioning. Now, with the soft starters, I am at ~ 70 amps for normal household PLUS both units starting at same time ... which is not real world scenario. This has been proved. If I bought a larger size generator, it would be so expensive, and too large for my neighborhood to accept the sound level, plus, running load is on a larger generator would be about 30% and that is NOT a good operation for long-term engine running ... increase of deposits on cylinder walls and heads. Not everyone is wealthy to overbuy a generator and not everyone lives in the country where they can install generator 100 feet from their home to reduce noise level.

You may consider getting a 25k ohm 20 watt resistor with wire/alligator clip on each end to bleed your capacitors. It’s a slow bleed that won’t damage your capacitors. I use one especially for electrolytic capacitors. It takes about thirty seconds to discharge and is the best method for bleeding them.

[@56nomadman]

Great video Dmitry!

[@jwhite4]

Nice video. Energy savings - I was going to post this as a reply to a post below, but thought I'd make it a separate post. I don't think it will provide any savings. As Dmitry commented below, the amp reduction is only for a brief while, at startup. So while that technically does save some current ($), the compressor isn't doing as much work (as much cooling). It will bee to run longer to make up for the missing BTU's. It converts that huge bu brief current spike to a lower but longer current draw. At the end of the day, it'll end up being the same total current draw. I don't think any soft start manufacturers advertise energy savings as a benefit. Also thanks to the poster that determined that the Flex is an all-capacity, but 25% smaller unit, than the original Breeze, which you had to buy in 3T, 4T, or 5T capacities. I only need a 3T unit for my house, so a ~$299 3T Breeze might be fine. Deciding if it's worth getting the Flex, figuring the smaller unit might (and latest and greatest version) might be worth the higher cost.

[@richlikeg3722]

I think having compressor soft starting compared to the hard starts will increase the life expectancy of it. Not sure if I read that somewhere? 🤔

[@co7366]

Correct. Imagine pressing your cars gas pedal to the floor and then going from park directly to Drive vs slowly accelerating to the appropriate speed. A lot of wear and tear in the long run. It saves some electricity as well

[@JimGnatek-y7z]

If you use the bluetooth feature to monitor starting current and number of starts you may find that it may have faults due to a capacitor or loose wiring problems. Micro Air was very helpful in solving these problems for me. You may also find that the compressor does hum louder on startup as time goes on.

[@aholmes6612]

What I have found is that you have 5 learn starts when installed. I installed mine when it was cooler during the spring but once we got to 100 degrees everyday I had a fault, so I reset it to learn all over again...problem solved.

Had the Micro-Air Easy Start Flex installed by my HVAC company last week on my 5 ton Carrier unit that is 14yrs old. LRA is 117a on the label of the unit. It is now 24.5/34a on start up. A couple of things I learned from tech support. Bluetooth signal is low power so you have to be within 2ft or closer to connect to the app. Also any solid stream of water like sprinklers or water coming off the roof in direct contact with the Flex , water will intrude and void the warranty. I asked about applying a bead of clear silicone around the window and where screws were. They said that would void the warranty. They suggested a water proof box to put the Flex in like other customers have done.

[@DmitryBrant]

Hmm interesting, thanks for that note. I guess by making the unit smaller, they expect more users to be able to install it inside the panel itself. But I do recall reading that it's supposed to be IP65 rated, which I suppose is for general "weather" resistance, but it sounds like they're being sticklers about specific types of water presence around it.

[@michaeladams4592]

Will not void your warranty with MicroAir. It is IP65 rated, they even say you can mount it outside the compartment if there isn't room for it inside. Just make sure you install with the wire exiting downward to be on the safe side (in case of pooling on the waterproof grommet). If your HVAC company told you that, maybe they were referring to their own installation warranty or something.. but MicroAir themselves are extremely supportive and state on their own videos these can be installed externally/in contact with elements.

[@GH-wt7ww]

@@michaeladams4592 I agree with the wire exiting downward and so far I have been very pleased how the starter has been working. Everyone will have a different situation to their application but be mindful where it is installed. Mine is installed on the exterior above the liquid and suction lines since there was no room inside the panel as you did and never any pooling. I asked tech support if I could just add a small bead of clear silicone on the seam where the box and clear top meet and where screws go in for extra added water protection since we get a lot of high winds and heavy rain here in Houston, Tx. This is a copy and paste from tech support response. They do not want direct water hitting them. " The starters are IP65 rated meaning they're water resistant but can't be installed where they'll direct roof runoff or main sprinkler water hitting them." You'd do better to make or purchase a box to mount it in like I've seen several other customers do. Do not add any kind of sealant or this will void your warranty.

[@cezarnebun9607]

FYI...LRA is when the motor is fully locked, not spinning at all...when we test motors at work we only perform the test for less than a second in order to not burn the motor windings. Sure the motor does pull a lot of amps when starting up but will never be at LRA spec since it is not truly locked up. Great video, btw. I am really surprised that they don't include the installation hardware, especially for the price.

Another comment said it is low energy Bluetooth, so it would have limited range anyway.

[@DmitryBrant]

Haha yes, I realized it has a bluetooth function after I already installed it, and you're right that it's basically inside a faraday cage, but I was able to communicate with it within a couple of feet.

[@AshtonCoolman]

@@DmitryBrant I bought some magnetic, rubber covered feet for mine on Amazon. They arrived today. I'm going to just slap mine on the outside of my unit with them. It'll also let me hide it under the panel if necessary.

[@Bill_CBR]

Would have been nice if you had recorded the actual starting current (peak in-rush current) as well as what is the actual running current while the compressor is running.

[@aholmes6612]

Min went from 150 down to 37 and running at 10.9

[@co7366]

He mentioned in another comment peak Amp is 30 and live now is 13A

[@kogiekobayashi3421]

I am interested to get it for my 2.5 and 4 ton Trane. What model and where did you get it? I have inquire and some air conditioner company ask for an arm and a leg to instal it.

[@Dillinger128]

my flex did 7 learn starts. did yours?

[@Simple_retired_life]

Can you please share where you purchased it? Website link . Tfs!!

[@dodgee_doo]

I hate that I cannot monitor error codes and I have to send the data to the company to get results back. That's the only thing stopping me from recommending it.

[@hjjordan2]

Does the wiring harness come with the product in the box?

[@DmitryBrant]

Yes, the unit comes with the wires already coming out of it.

[@GatoGamingSi]

I've been looking for one for my house but the ones on Amazon seem to be for RV use. Where did you get yours?

[@LygerTheCLaw]

how much better is this that a hard start cap? i mean it is almost 100 times the cost.

[@ZimorKilled]

A hard start provides more power to start a compressor. Soft start is opposite, it reduces power to start the compressor and fan motor.

[@liltiti86]

What easy start do I need for a 5 ton 150Lra

[@jameschuke4104]

Put a amp meter on your hot wire out n see max amps before n after

[@simprophet]

How does an air conditioner cool down a house?? 0:40 In Rush Current

[@Monztuh]

Lol i get it bro

[@marct9587]

So, what did you do with that wire that was originally connected to the herm terminal on the capacitor? Did you terminate it with something?

[@DmitryBrant]

That wire stayed on the Herm terminal; The new wire was in addition to that one. (The capacitor terminals have multiple connectors that you can plug onto, exactly for these kinds of purposes)

[@davidgentz1731]

Basically what you're getting is a start capacitor and then they're probably bring it on the condenser fan a little different time maybe before the compressor but unless you have a adjustable speed compressor you need to get that thing a shot and get it going and that's what they're doing and that's a can of a scam they've had that for years

[@jbhobbyist9372]

Are you aware there is an app to monitor your micro-air?

[@DmitryBrant]

haha yes, I realized it has a bluetooth function after I already installed it. The app says the peak current is now 30A, and live current is 13A (and no faults).

[@jbhobbyist9372]

@@DmitryBrant Great!

[@Bill_CBR]

@@DmitryBrant That's a significant reduction in current. Looking at your label shown at kzbin.info/www/bejne/joCxoGSCipeMaqcsi=1EkMGSERWBoTFPup&t=116 it indicates a RLA of up to 26.8 amps and an LRA of 134 amps. That's huge. Thanks for sharing.

[@co7366]

@@DmitryBranthave you noticed lower electric bill by any chance? Judging by current usage being dropped by half, I wanna be optimistic and say you have ? 😀. Thanks so much for a great video

[@jameschuke4104]

Not a relay contactor

[@Sam-ys4pc]

Dont put one of these in, they destroy compressors. My Hvac guy said never put them in. Hes always disconnecting them. The hype thats going around about them is incorrect. They donot reduce current to the motor, you cannot measure correctly with a clamp meter.

[@avflyguy]

This really isn't a review. His goal was to reduce the noise it made. After statup should it not sound the same? Would have been nice to have seen a meter to capture start up Amps, then running amps. I'd like to do that on my 4 ton, but don't think my 5500 watt gen would work.
