I would confidently recommend HVAC Keeper to anyone looking for reliable AC repair, HVAC diagnostics, or residential HVAC service.

Two AC units in our restaurant stopped working at the same time. We contacted several companies, and only HVAC Keeper was able to confidently tell us that the problem could be resolved by the next day. I would like to express my sincere gratitude to HVAC Keeper for their professionalism, excellent management, and highly skilled technicians. I highly recommend those guys to anyone looking for reliable commercial HVAC repair, emergency AC service, or a dependable HVAC company in Thousand Oaks.

HVAC Keeper did an outstanding job at our multi-unit complex on Kestone Ave in Los Angeles. Other companies recommended a full system replacement, but HVAC Keeper took the time to properly diagnose the issue and repair the system instead, saving us a significant amount of time and money. Their technicians were honest, knowledgeable, and focused on finding the most practical solution rather than pushing unnecessary replacements. Most importantly, they were able to restore cooling quickly and keep the tenants comfortable during a major heat wave. We truly appreciate their professionalism, fast response, and expertise in commercial and multi-unit HVAC systems. Highly recommended for anyone looking for reliable diagnostics, repairs, and honest HVAC service.

HVAC Keeper did an excellent job on our new commercial sports club space in Santa Monica. This was a complete HVAC installation from scratch for a new tenancy, including new units, ductwork, and the entire air distribution system. Their team carefully reviewed the blueprints and matched them with the real field conditions, making all the necessary adjustments to meet code requirements while maximizing efficiency and functionality for the space. They were extremely detail-oriented and made sure the entire system fit the layout perfectly. What really stood out was their professionalism and coordination with other trades on-site. Everything was completed quickly, efficiently, and with great communication throughout the project. The final result exceeded our expectations, and the quality of the installation was outstanding. We highly recommend HVAC Keeper for commercial HVAC installations, especially for complex tenant improvement projects where experience, efficiency, and problem-solving truly matter.
