FAQ

+

Q1. Is a SoftStart Home device basically a transformer? If not, what’s the difference?

A. No. SoftStart Home is NOT a transformer. Transformers either step up or step down voltage. A SoftStart Home is a solid-state system that protects A/C and heat pump motors and compressors from damage caused by sudden influxes of power. It greatly limits the inrush of high current typically associated with the motor startup of an inductive-load device, such as an air conditioner or heat pump. SoftStart Home provides a gentle ramp up to full speed (0.06 sec) and only works during startup.

Q2. How is SoftStart Home different from a Hard Start or Start Assist?

A. A Hard Start or Start Assist is a device that stores a large amount of power and releases its power all at once. That is why you hear a heavy thud when a motor/compressor is started with one of these devices. Hard Start and Start Assist devices are hard on the motors and compressors due to the extreme heat created by the large electrical inrush that they allow to reach these vital components. 

Q3. Is a SoftStart Home unit watertight and able to be mounted outside the A/C unit?

A. A SoftStart Home is water-resistant and should be installed with the wires pointed down, preferably inside the air conditioner or heat pump housing.

Q4. How long will a SoftStart Home unit last?

A. SoftStart Home is built to last for many seasons, but it is an electronic device and there are many factors that can shorten the life of electronics.  

Q5. What is the warranty on the SoftStart Home?

A. SoftStart Home is warranted for three years with online registration.

Q6. How does a soft start actually work?

A. SoftStart Home is a solid-state system that protects A/C and heat pump motors and compressors from excessive heat damage caused by sudden influxes of power. It greatly limits the inrush of current associated with motor startup by providing a gentle ramp up to full speed (0.06 sec) SoftStart Home only works during the startup, then it gets out of the way until it’s needed for the next startup. It does not operate while the air conditioner is running.

Q7. Can a SoftStart Home replace a hard start device?

A. Yes! The SoftStart Home can and DOES replace a Hard Start or Start Assist (to use a SoftStart Home, the Hard Start or Start Assist device MUST be disabled before powering up your unit). The SoftStart Home performs a “self test” before starting. If it detects the presence of a Hard Start or Start Assist device, it will not power up (a red light on LED 3 will appear). 

Q8. Can a SoftStart Home replace a surge arrestor?

A. A SoftStart Home does not offer typical surge protection capabilities.

Q9. What type of compressor will a SoftStart Home work with (single-stage, two-stage or variable)?

A. A SoftStart Home will work only on single- and two-stage systems – not a variable speed system.

Q10. Does a SoftStart Home work on refrigeration systems and circulator pumps?

A. SoftStart Home will work on refrigeration systems, but it will not work on circulation pump motors.

Q11. Can a SoftStart Home be taken off an old A/C or heat pump unit and reused on a new or different unit?

A. Yes! The SoftStart Home can be removed and used on a new unit if the older one is replaced. Installation may be different on the new A/C or heat pump, depending on the brand of the units.

Q12. Does each A/C or heat pump unit need its own SoftStart Home device?

A. Yes. Each A/C needs its own SoftStart Home unit if there are multiple A/Cs.

Q13. Will a SoftStart Home affect the air conditioner manufacturer’s warranty?

A. It should not affect the warranty, but it depends on how the SoftStart Home is installed. A SoftStart Home uses wiring connectors that work on many units without changing any wiring connectors. However, there are some air conditioners and heat pumps that require changing one or two wire connectors on the last step of the SoftStart Home installation.

Q14. Is the SoftStart Home unit tested?

A. The SoftStart Home is tested at the factory to withstand temperatures ranging from -40ºF to 185ºF. It is also cycle tested to last more than 100,000 cycles and operate more than 45,000 hours at working temperature.

Q16. There’s a green light on the SoftStart Home unit, the A/C is running, but there’s no reduction of in-rush current?

A. Step 1) Follow the Red Compressor wire FROM the Compressor TO Contactor Block T2 Terminal, Disconnect cut fork terminal off crimp Female on RED Compressor wire, Connect to Blue Softstart wire.

Step 2) Connect Black Softstart wire on a male spade BEHIND where Red Red Compressor wire was.It is important to follow this to achieve the reduction in inrush current.IF you disconnect the Red wireFROMthe Run Capacitor“C”terminal and connect it to the Blue Softstart wire and connect the black Softstart wire on the Run Capacitor“C”terminal. The SoftstartWILLget a green light and the Compressor is RUNNING but there will be NO REDUCTION in inrush current because it is a 14 gage wire even though the 10 gage and 14 gage are on the same post.If you connect the Softstart 14 gage Blue directly to the Compressor wire from T2 and connect the SoftStart Black 14 gage to T2 male spade, the inrush is reduced by 50 to 75% of normal inrush current.Also to correctly capture the inrush you MUST use an inrush meter that can capture 6,000 reading per second because the Softstart starts the compressor in 6/10th of a second.

Amazing product that works perfectly

AK - TX

Installed on a 2012 Goodman R410 condenser. I have a Tesla powerwall whole house backup system and every time the AC went to turn on the system would fault out despite the tesla survey person saying it would work. After installing this, it works perfectly every time with no issues whatsoever. I would recommend anyone with a home generator needs one, and to be honest even if you don't it lowers the starting stress on your compressor and even runs quieter - AK TX

This SoftStart is a game changer!

Richard John S.

This gadget does everything they claim. I have a Predator 9500 generator that will run the whole house but not the AC ( 3.5 ton Carrier). Well, after Danny, SoftStart customer support, made a wiring diagram just for me and my AC unit. It made it really easy to install and he is a really great guy. This is well worth the money and I could not be happier. I highly recommend it.

Great for saving your AC system

Wilson

This device adds life to your system by saving your compressor from the inrush current spike it takes to start everything. It also acts as a surge protector in the event of lightning. Also, by bringing down your inrush current, you will be able to run your house off a 30Amp 220V generator, without any trouble. A great investment!

Good product, easy to install

Larry M.

We bought these products about 5 weeks ago for each of our two central Rheem A/C/ units. We had discovered that our backup solar, battery or generator power could not always start up the 'ac units depeneding on what other loads were on-line. There would be a loud start up "thunk" and then the AC would shut down. I was thinking I might need a professional to install these, but actually the SoftStartHomes were easy to install following the accompanying instructions, maybe 20 minutes to install each one.

Will the SoftStartUp reduce the power consumption of my RV appliances?

The SoftStartUp does not decrease the power used by your appliances during normal operation, which is actually beneficial. Each appliance has a specific running current necessary for proper function. The SoftStartUp specifically addresses the surge of power needed at startup, reducing its impact to ensure seamless operation of your devices on the same electrical circuit.
