What a wonderful experience, JJ contacted me immediately by text message after he read my request for help with installation of my dryer duct work. He made room for me between other obligations and without hesitation, he had solved my needs. After he left I had another question and 1/2 hour later, he showed up again and helped me with something that wasn’t even in the original contract. Can’t thank him enough. Thanks JJ. I highly recommend Cen-Cal to all.

I had my dryer duct replaced and upgraded from flexible to rigid duct. JJ & Amir came with thier technition and all worked together to finish the replacement in the crawlspace. Previously, I had lint accumulating in the very long flex pipe causing dryer sesnor warning. Hopefully with the rigid pipe and proper periodic cleaning, I won't face the issue again.

JJ was professional, punctual, and responsive in my query about inspecting the vents in my bathrooms for potential leaks. He did a thorough job of inspecting the attic to rule out leaks. He also inspected the roof to confirm. He established trust through his actions and expertise. I would work with him again.

I recently hired Amir to fix my air conditioner, and overall the experience was very positive. They were responsive from the start, scheduling an appointment quickly and arriving on time. Amir clearly explained the issue with the unit in a way that was easy to understand, which I appreciated. The repair was completed efficiently, and they made sure everything was working properly before leaving. I also liked that they were transparent about pricing—there were no surprise charges, and the cost felt reasonable for the work done. They kept the work area clean and were respectful of my home. Overall, I would recommend Amir for their professionalism, clear communication, and reliable service.
