HVAC reviews in Santa Clara, California

Sunset Household Services provided outstanding AC system installation. Their team was professional, punctual, and handled the entire process with great expertise. They ensured everything was set up correctly and took the time to explain the system's features. I highly recommend Sunset Household Services for their reliable and skilled installation services.

Sunset Household Services delivered excellent heating and cooling services. They handled both our heating and cooling issues with skill and efficiency. The team was knowledgeable, professional, and made sure everything was working perfectly. Their reliable service made a noticeable difference, and we’re very satisfied with their work.

Can't thank them enough for having an emergency furnace repair. It was a cold night when our furnace broke down. Their technician was quick to respond and fix the unit. Huge thanks.

I came home during a heatwave to find the AC not cooling properly. The technician found a refrigerant leak and repaired it on the spot. The cold air came back within hours, saving the day.

When‍‌‍‍‌‍‌‍‍‌ I needed an emergency HVAC repair done at my place in the middle of the night, these guys were really quite ‍‌‍‍‌‍‌‍‍‌amazing. The technician arrived quickly and was able to get the system cooling again in a very short time. I'm really thankful to them for being ‍‌‍‍‌‍‌‍‍‌available.

Really fun place to be at. You can make and meet new friends that prove to be very kind here. Definitely offers great certifications that are in good demand!

They gave me no help at all.... not even a referal.

We’ve been working with Bay Area Mechanical for about four years across eight of our locations. What started as regular maintenance services has grown into a great partnership that now includes service, repairs, and installation projects. Their team always provides clear options and takes the time to explain what’s needed. We really value their professionalism and the quality of their workmanship. They’ve become our go-to HVAC company, and we trust them with all of our locations.

Great experience working with Bay Area Mechanical as a subcontractor. Their team was friendly, professional, and easy to coordinate with. Communication was clear, and everything ran smoothly from start to finish. Looking forward to working together again!

Bay Area Mechanical is my go to company when I am in need of repairs. They are quick to respond and communicate very well. Everyone in the office is extremely polite and great to work with.

We’ve worked with Bay Area Mechanical since 2019 (over six years) at our San Jose facility. Their preventative maintenance program is thorough, they catch issues early, and as a maintenance customer, we receive a 2-hour response time when emergency service is needed. Professional, reliable, and easy to work with—highly recommended.

We consider Bay Area Mechanical a trusted mechanical contractor for the Palo Alto Elks Lodge. They support our comfort needs (HVAC/heating/boilers) and our operational needs (kitchen refrigeration, ice machines, exhaust, etc.). Their preventative maintenance program has kept our equipment in excellent operational condition, and their emergency response has helped us quickly restore critical systems when failures occur. I would highly recommend their services for large or small facilities.

Esi did a great job servicing our building for our Gym space. They were super easy to communicate with. They were really transparent and I would use them again!

We have been using ESI for over 13 years to install and maintain our HVAC system at our small business. If you are smart, care about keeping your HVAC running, and want to be appreciated as a client, do not use this business.

ESI is a great company to work with. We have worked with ESI on many projects for the past 15 years. They are very professional, excellent customer service and technicians. It’s always a pleasure to work with ESI crew.

Great group of people
Helpful, dependable and reliable. Excellent work ethics.

T3 Mechanical assisted us with HVAC for our room edition

Great service

Great and prompt service. Would recommend to everyone

Shlomi and team did excellent work at a Fair Price! We required a full replacement if the air ducts and also did a full cleanse of the AC Unit and furnace. All work was timely and easily passed city inspection! Highly recommended!

They came immediately within one hour after my call. Very knowledgeable and professional people, getting the diagnosis and repair done very quickly. I appreciate their hard working. 👍
