Contract Postal Unit

Haik and his team were prompt, courteous & professional. Haik was able to answer all of our questions and the work was done completely to our satisfaction. I would definitely recommend Mastermind Mechanical to anyone in need of their services.

I highly recommend this company. We replaced our ac and furnace and from the first phone call, it was a great experience. Haik was very professional, on time for everything, respectful, honest, and informative. He knows what he's doing and was great at making sure we were on the same page for everything. The system runs great and I would absolutely choose Mastermind again.

Haik is professional and reasonable price. We have been using him for years to help us with our system. He came quick and got it done fast. Highly recommend him.

My air conditioner stopped working on a Saturday and on a day here in Vegas when it was 112 degrees outside. I called around to several places and no one answered until I called Mastermind Mechanical. Haik answered the phone and said he could be here within the hour. Not only did he keep his promise and showed up 20 minutes later but he diagnosed and fixed the problem! This honestly was the best experience I’ve had here in Vegas dealing with a repair company. He was honest, knowledgeable, fast, gave a fair price, and I will for sure use him again in the future and refer him/ the company to everyone I know.

I submitted a service request at 7:00 am and had someone here by 9:30. Haik was knowledgable and explained his recommendations thoroughly without any high pressure sales tactics. Would recommend to anyone with A/C service needs!

Real coastal, unique, and small post office. This place is filled with trinkets and gifts. Great customer service.

I live in Novato and was running an errand near by. This “post office” is a breath of fresh air! Customer service was stellar! I will make the drive just to use this adorable post office again!

Wonderful service. I normally dread visiting the post office but this experience has restored my faith! Lovely interaction (the post master gave me tips for my hike in Marin Hills). I will now save up my post office trips for when I'm visiting Larkspur. Thank you .

Update: this post office DOES sell postage. I was able to purchase international stamps!!!
