⭐⭐⭐⭐⭐

Shaun did the initial troubleshooting and also did the actual work on my HVAC (AC). He was very professional and courteous. He was helpful in answering my questions regarding the AC issue. He made sure everything was in perfect condition after completing the job. I would recommend Shaun for sure. I also discussed with him about doing a yearly maintenance check on my HVAC.


- Manny I.

⭐⭐⭐⭐⭐

Shaun repaired our AC by replacing the refrigerant after it was blowing warm air. Shaun was very accommodating to our hectic schedule since we just had a baby, and worked around our needs and delays. He was professional, quick to schedule the work, negotiated directly with our home warranty, and completed the work with high quality. Thank you!


- Bajis K.

⭐⭐⭐⭐⭐

Shawn has got to be the most humble best mechanic I've come by in a long time. He's very very thorough and will not consider the job complete until he feels he has solved the problem and what has caused the problem. 100 percent recommended. Will definitely be number 1 on my list to call for future problems.


- Bubba

⭐⭐⭐⭐⭐

Shaun is awesome. He came in and fixed our problem in a timely manner. Very respectful and professional. I’ll recommend his services all the time.
