They did not really trouble shoot. Insist the board has problem n need to take back machine to workshop to repair. Quite disappointing.

Prompt and great service.

They performed the task professionally and check holistically the aircond system. Highly recommended.

Experienced, efficient, clean & friendly.

Perfect

Friendly , professional and quick service. Initially I just needed a quick refill but these guys found an issue and fixed it at no extra cost. Thank you and I’ll be hiring you guys again.

Very good service, good workmanship and reasonable price. Thumbs up!
