FAQ

What clients ask before starting

Do you solve voltage dips, surges or harmonics?

Yes. Power-quality problems — voltage dip, sag, harmonics, electrical noise and transients — are part of our electrical scope. We diagnose and report first, then propose a fix with a price.

Do you work on residential and office buildings too?

Yes. Our electrical scope covers both industrial plants and buildings — for example The Green View Hotel in Pattaya and rental offices and accommodation for KK One Corporation.

Can you work outside business hours or during shutdowns?

Yes. Most of our factory, hospital and showroom work is done outside operating hours or during shutdowns so production and occupants are not disrupted.

How do quotations work? Is the assessment free?

A preliminary assessment from drawings, a TOR or site photos sent on LINE is free. For site surveys on larger projects we explain the terms first. Quotations are itemized — equipment, labour and materials shown separately.

Can you issue tax invoices to companies?

Yes. We are a registered company and issue quotations, invoices and full tax invoices, with billing and credit terms as agreed.
