Every time a Bob Jenson rep comes out to do my HVAC maintenance they do a wonderful job, they are polite, speedy, and make sure the system is running smoothly. They don't overlook anything.Pouria came out most recently for regular maintenance and was very kind and professional, he was respectful of my space and my pets. He was quick to point out a potential issue, explain what could go wrong, and made sure to let me know it would be addressed quickly so that the system wouldn't have any issues. He made sure to clean up dust and smudging from changing the filter and didn't leave any mess behind.I'm always so impressed with the service reps from Bob Jenson and this was no exception. Thank you Pouria!

We have been with Jensen for over 5 years. They installed a split system in our house in east county. We pay for a maintenance plan, so a technician comes twice a year to clean the filters and check the whole system.Yesterday, Pouvia was our technician. He provided excellent service! He was on time, friendly, efficient, and conscientious! He took the time to explain what he was doing and showed me a picture of our filters before and after cleaning! What a big difference! Pouvia also was careful to cover his shoes with covers each time he came in our house, to protect our carpets from dirt. I'm glad we continue to do business with Bob Jensen Heating and Air Conditioning!

I need to give a big shout out to all the individuals that helped with the replacement of my old heater/air conditioner. First CyrusThomas came to service my unit, noticing it was not working well. On the same day Mike Da Luz was able to come out and give me an estimate. This week Luis Garcia with his crew: Jorge Curiel and David Brito came out and in two days removed the old unit and put in a new, more efficent unit along with new air ducts. It was a lot of hard work but they were very professional and curteous.It helps when there is a good, cohesive group of individutals working together. Louis thank you for taking the time to show me how to navigate the thermostat and new app for my phone.

We would like to commend the team, from Bob Jenson Heating and Air Conditioning, comprising of Antonio Guadurrama (Team Leader), and his associates Jorge Curiel and Luiz Garcia. Their professionalism, knowledge, and commitment to excellence were truly exceptional. They were at our residence replacing and installing a new heating and air conditioning system. Throughout the procedure taking a day and a half (March 4&5), we were also impressed by their courteous and thoughtful manner. Our thanks and appreciation to Antonio as well as to Jorge and Luiz. They are a credit to the Bob Jenson organization.

1709763262

We have been customers of Bob Jenson for 25 years. Always great service. Today I had the maintenance done. I was especially pleased with how I was treated. From booking the appointment with Ellice in the office all the way to Cyrus doing the actual maintenance... just great people to work with.

We have a maintenance contract with Bob Jenning and are always happy with their work. Cyrus is an excellent tech.

1709594358

They did our air conditioning a few years ago and have provided excellent service since then. When our furnace died of old age they worked with us from estimates through completed project. Each step was as easy as possible. The price was fair. The workers were great. Even when we had a setback—no one’s fault—they immediately helped overcome it and we got the project completed. The installers were very efficient and helpful throughout. I must say we used them without other estimates based on their estimates on our air conditioning before and from service to estimates to installation it was a great process. Would use them again anytime.

1709231724

We have regular maintenance of our heat and air conditioning systems by Bob Jensen and are happy to have their help. Gino was here today and did a thorough inspection, complete with photos, of our system. We have an older, drafty home so we depend heavily on Gino and the other techs to keep it cool in summer and warm in winter. We recommend Bob Jensen.
