We go back in time to follow the invention of the Air Conditioner down thru history to our modern day. Check out our latest, fun infographic!

Marcella is amazing and makes you really feel heard.

I have been using Bob Jenson's for over 20 years and just purchased a new HVAC system with them. I am pleased with the product and so very impressed with the 2 technicians who installed that system. Tony Guaderama and Pouria were efficient and kept me advised as to what they were doing...they were a pleasure to have in my home. Highly recommend Bob Jenson's . From the moment you speak with Marcella and then get your needs met, you will be happy with the service and product.

This review to to commend the friendly, skilled and overall great guy - my technician, Marcos Frias. He turns up on time, listens to any concerns and quickly gets to work. I’ve been using Bob Jenson for my routine service plan for a few years now, to keep all my furnace and split AC units up and running and in top condition. I am extremely satisfied with their service and will use them in the future, should I choose to upgrade my equipment. Cheers!

Tom was super knowledgeable and was very good at quickly diagnosing the problem with my AC. He was able to clearly explain not just what went wrong, but also what caused it and what I can expect in the future.There are parts changers who just make guesses and then there are technicians who can diagnose and repair. Tom is definitely the latter! 👏🏻His professionalism and expertise was the reason I joined their maintenance club program in order to extend the life of my AC system.A+ service!

Bob Jenson is the only company I'd trust to service my HVAC systems! All of their techs have been professional, knowledgeable and very respectful of my property while onsite. Cyrus is an absolute gem and performed maintenance on both my mini split and central system. He even gave me advice on how to maximize airflow on my mini split since it is in a bigger space. Thanks a ton!

Just got our tune-up/checkup from tech Cyrus Thomas and appreciate his communications and professionalism. Our 24-year-old Lenox HVAC is operating like a charm! Nice to be able to trust a company in the old-school way.Excellent company, customer service, integrity, quality of work

Bob Jensen's company has been taking care of my heating and cooling needs since 2000. They have always gone above and beyond to take care of me. I would highly recommend them to anyone. Above all, they are honest and have never done anything that didn't need to be done. They have me as a customer for life!

She is always professional, efficient, friendly and thorough. I enjoy her calls.

It only took them three days to install two very difficult units. From taking out the original two from the 80’s that stopped working. They were on time, polite and left everything clean at the end of each day. Javier Zambada, Luis Garcia, Leo Juarez and Mike Daluz did an amazing job.

I've been doing business with Bob Jenson since 2008. Any issue I ever had they were able to resolve. Recently I had a new HVAC system installed. Things went smoothly, basically because of the great attention to detail I received from Customer Rep. Marcella Gorghis. She rocks! You cant go wrong with this company.......and Ms. Gorghis!

After talking to several other companies and getting the complete runaround, Bob Jenson was a breath of fresh air.Their tech, Tom, was able to diagnose our problem, explain it, and provided by far the most reasonable quote to replace the failed system.Their install team, Javier Zambada and Luis Garcia were professionals throughout the install, communicating at every step of the way.10/10, would recommend to anyone in the San Diego area if you have an AC issue.

Both office and technician personnel are knowledgeable and helpful. Great company to do business with. Marcella is very helpful in scheduling normal and emergency repair calls.
