Mak was outstanding working on our complex Mitsubishi mini-split system with multiple indoor units. Another technician had told us we needed to replace the entire system, but Mak took the time to thoroughly diagnose the actual problem instead of jumping to the most expensive fix. What impressed us most is that he didn’t even need to call Mitsubishi’s technical support line — he knew the system well enough to identify and resolve all the issues on his own. Saved us from an unnecessary full replacement. Knowledgeable, honest, and efficient. Highly recommend!…Read moreCentral Air Conditioning Repair or
Maimax did a great job by detecting the issue quickly and fixing it efficiently. I recommend them for HVAC jobs without hesitation.
Excellent experience with Marimax. Showed up when they said they would, diagnosed the issue and professionally repaired it. I highly recommend this HVAC service provider!
Good experience working with Maksym. He did the initial maintain r and then was able to return to fix a new problem that arose.
Highly recommended. Stayed until the furnace was fixed. Very professional.
