Delta Sierra Mechanical

The final inspection by the City of Stockton was today and the system that was installed by Delta Sierra Mechanical passed. There was never a doubt in my mind that it would not pass. The technicians took their time and installed the system properly and as neatly as possible. I am extremely happy with their work and attention to detail.

The service tech Henry, replaced my thermostat and reset the system so I could resume controlling my system via the app. He also suggested purchasing the HVAC twice yearly maintenance plan which was money well spent. This was my first time having my system serviced by Delta Sierra Mechanical, and I am EXTREMELY pleased and would HIGHLY recommend them.

The crew was on time, professional, and they finished before dinner, which I was impressed, great service and a great deal, highly recommend the Delta Sierra crew

I had my regular HVAC maintenance service today, and Adrian was excellent. He provided clear, detailed explanations and was very friendly throughout the visit. I really appreciated his professionalism and great attitude.

I had a new AC/Furnace unit installed. They did such a fantastic job. I just wanted to give a special thanks to Mike the owner who worked with me throughout the project. The Gentleman that were at my house doing the install did a fantastic job. One name stands out above the rest and that name is Brandon. If you do have to get a new system installed you absolutely want him out there. Thank you To "Team Delta Sierra Mechanical".

This company is great! After being told by another company during a routine ac and furnace tune up that both their motors were leaking oil I contacted my home warranty company, American Home Shield (also great) and explained what was going on and they arranged for Sierra Delta Mechanical to come to my home and check things out. From my initial contact with their office when they called to set, and then later confirm the appointment, all the way through the technician coming today the employees were great! Our technician Henry arrived on time, he was very respectful of my home, he spent a lot of time looking at both the ac and furnace and explained in detail what he saw. He gave me a lot of useful i formation that I plan to pass on to people in my retiree group. I would 100% recommend using this company, and i feel like Henry was very knowledgeable in his craft and I he has definitely put my mind at ease. Thank you!! Kathy K.

Our technician Henry arrived sooner than expected and that was actually better timing for us so it was perfect! He was very polite and informative with providing us different options. Not only was he informative but very honest and completed the service in a timely manner. He is definitely representing your company in an expertise manner. If we ever needed another service, we would request our tech.
