What recent reviews say

One reviewer reported that ERSA's condensation treatment failed to stop a leaking grille after application, and the business refused a refund citing a non-refundable policy. The reviewer suspected the company had misdiagnosed the root cause.

Based on limited recent reviews, so treat this as low-confidence.

Watch-outs
  • Service did not fix the problem
  • Non-refundable policy despite failed work
  • Blamed external factors instead of their solution

Highly rated for honest, detail-focused servicing when technicians like Aung, Lucas, and Jay show up; many repeat customers over years. But recent complaints flag communication gaps, unexpected price hikes mid-service, and inconsistent follow-ups when problems recur.
