Two Year Limited Warranty

I wanted to send a note to thank the Service Technicians that helped me yesterday. I recently inherited my father’s self-serve car wash, and do not know anything about your products. The machine was not working properly and I called. The technician asked me a few questions, and walked me through the troubleshooting process. After a few tries – we were back up and running. It was wonderful to be able to call a company and talk to a knowledgeable person.

I will recommend Standard Change-Makers to anyone in the car wash industry as a trusted and reliable partner.

Sara Ann Malone, Big Suds Car Wash

Thanks! – I have dealt with Standard Changer Company both as a distributor and a customer for 40 years. Thanks for being the one company in the coin laundry industry that has been consistently solid, maintained excellent customer service, and continued to make their SC series products with the same high quality standards for that entire 4 decades. That is almost unheard of in this day and time. — Also, hats off to your outstanding parts and service team.

Because I manage multiple stores, being able to receive email alerts via the EF+ Module when my bill cassettes are low is an important time-saver!

Knowing when to refill bill cassettes means our patrons can always break $20 & $10 bills – which improves our customer service.

Bruce Gilliat, Las Vegas Coin Ldy.

The new EF+ Module is perfect for the passive owner. I would recommend this new device for anyone that needs to see how the businnes is doing when they can’t be there.

I’m not at my store every day, but I get daily audit reports from the change machines. It was easy to install and set-up. Now, when I fill my hoppers, I enter the starting amount and set the low level amount – so when it starts getting low, I get a text alert on my cell phone. It works great!
