Can I install a Soft Start Unit on my MrCool Universal 5 Ton?

First off, what is a soft start unit? A Soft Start Unit, or a start assist kit, is an accessory designed to enhance the performance of your air conditioning unit. It primarily targets the compressor, which is the heart of your AC system.

Why is a Soft Start unit Necessary?

Soft start units reduce power surges. When your AC kicks on, it requires a substantial amount of electricity to start the compressor. This sudden surge in power can strain your electrical system and, over time, lead to premature wear and tear. The Soft Start Kit mitigates this by gradually ramping up the compressor's power, reducing power surges. It extends the lifespan of your compressor. Compressors are one of the most expensive components to replace in an AC unit, so this can save you money in the long run. It will improve the efficiency. It allows your AC to start more smoothly, which can result in increased overall system efficiency. This means your AC will use less energy to achieve the same cooling effect, potentially lowering your energy bills.

Can I Install one on my MrCool Universal?

Sorry, Charlie, no you can not. BUT adding a surge protector to your MrCool Universal is a smart move to protect your system from voltage spikes and electrical surges. Surges can occur due to lightning strikes, utility grid fluctuations, or other electrical disturbances. By adding a surge protector, you are taking a proactive step to protect your HVAC and ensure reliable performance, especially during electrical disturbances and bad weather conditions.

Confused, you say how great a soft start is for your compressor, then turn around a say you can't do it ? Which way is it - yes or if no, why not ?

It is unfortunate that the question was not answered as to why a soft start is not necessary for Mr. Cool Universal units. Inverter compressors are variable speed and powered by direct current. They do not even have a "LRA" (Locked Rotor Amps) rating which is what a Soft Start unit would attempt to mitigate. They are variable speed compressors that start slow and ramp up to the speed requested by the motor controller. I have a Mr. Cool 5-ton Universal and it is uncanny to hear it start slowly then settling into a nice barely quiet hum.

Why can't you use a soft start ? Actually they should be required for everyone's good! Looks like manufactures are more Interested in building a cheep product rather than a good one.

Why doesn't it come with proper surge protection?
