SK Testing provides certified HVAC system verification for residential projects throughout Southern California. Under California's 2025/2026 Title 24 Energy Code, HVAC installations must be verified by an independent certified ECC/HERS Rater — your contractor cannot self-certify their own work.

We verify refrigerant charge, airflow measurements, and system performance to ensure your HVAC installation meets Title 24 compliance standards. Fast scheduling, same day CHEERS filing, serving San Gabriel Valley, Pasadena, Alhambra, Arcadia, Monterey Park and greater Los Angeles.

What we verify: - Refrigerant charge measurement - System airflow verification - HVAC installation compliance - CHEERS registry filing included

Cantonese and Mandarin speaking rater available. 提供粵語及普通話服務。
