Call us

(562) 805-3250

The phone is answered by a technician. If your line is down, call — do not email and wait.

Request a quote

For planned work, PM agreements, or anything that is not urgent, the quote form is the fastest route. Tell us the equipment and what it is doing and we will come back to you.

Hours

  • The phone is answered 24 hours a day, seven days a week. A technician picks up — not a call center, not an answering service.
  • On-site work runs Monday to Friday, 3:00 am – 1:00 pm. Early by design — it means we are on site for first shift, and often before your line starts.
  • After hours, weekends and shutdowns by arrangement, at a premium rate. If your only window is a Saturday night changeover, that is usually the right time for us to be there.

Response time

On site within 24 hours across our service area. When you call, you will be told when we can actually be there — not a best-effort promise.

Where we come from

We are a service-area business, so there is no counter to visit. On-site work covers Los Angeles, Orange, Riverside, San Bernardino, San Diego and Ventura counties. Remote support is available nationwide.

What to have ready

The first conversation goes much further if you have these to hand:

  • What the machine is doing now, and what it was doing before
  • Any fault code showing on the drive or controller
  • Nameplate data — voltage, horsepower, full-load amps
  • What has already been tried, and anything that changed recently

Not sure it is worth a call?

Try the free calculators and trainers first. If they get you to the answer, you have saved yourself a call-out — and we would rather you did that than pay us for something you could solve in ten minutes.
