Jensen Mechanical

I consulted with Ryan Jensen regarding my 33 year old HVAC system. Ryan was professional and gave me many options to correct the variable temperatures in my home. We contracted with Ryan and his company to replace the duct work, furnace and air conditioner.
Jensen Mechanical’s installation was considerate, clean and tidy and absolutely trustworthy. They communicated with me all along the way about what I would expect regarding the installation. I always felt safe when they were working around my home and the installation of the new system went smoothly. Chris and Joe (the installers) cleaned up each night before leaving the job and treated me and my home with the utmost respect.
I love my new system. It’s quite, heats evenly and I feel more comfortable in my home than I have in years.
I have nothing but good things to say about Jensen Mechanical and Ryan’s crew.

We use Jensen Mechanical for our AC/​heater services. This guy is very honest, professional with reasonable prices. The first time Ryan came in to our house, was last year during the winter time, he fix the heater. The second time we call him it was during the hot days of summer time. Our AC just stop working and we just melted in the house. Ryan came out as quick as possible and find out the problem! He replaced the part that was necessary to replace, he checked that everything is working well before he left. After couple days we notice that the AC unit stop working again. We called Ryan again! He came out the day after (and I know his schedule is busy, but still find the time to squeeze us in the schedule to come in). He checked again the unit and the thermostat. The problem was in the thermostat this time! He let us know that we don’t need to hurry to replace it yet. He make sure, he leaves after everything is working well. Since than everything was working well.
Thank you Ryan!!!
We will recommend your service for all our friends and family.

Fast, efficient, professional service at a reasonable price. Need I say more? Ryan is full of integrity and their office staff, Jennifer, quick to call back. Great customer experience.

Updated review because we had another great experience with Jensen mechanical and our AC. Ryan came out and reworked the way the condensation drains out the top story instead of the lower pipe. It took about an hour. After 10 years of water dripping down the left side of our house (builder error, as there are many in this neighborhood) it finally drains correctly, out the bottom pipe. We have had so many people look at the problem over the years and scratch their heads. And now it’s fixed. I recommend Ryan. He does good work, and solves problems that others can’t solve!

Ryan and his crew are top notch. He has taken care of our heating and air for the last 5 years with the utmost professionalism. Ryan even found the air conditioner work was under warranty, barely. The A/​C was put in before we bought the house and we never considered checking. Ryan checked on his own and let us know. He has made himself available the same day whenever we had a problem with our ancient furnace, keeping it alive as long as he could. A new machine was put in last year, and we couldn’t be happier.
Great service, pride, professionalism, gone above and beyond for us and as honest as they come.
We highly recommend Jensen Mechanical, without hesitation. They will be missed as we are moving and know how rare it is to find such an amazing company.
Thanks Jensen Mechanical! Thanks for the great service, thanks for being there whenever we needed you.

We were referred to Ryan by our electrician who has done a lot of work for us and the electrician told me Ryan’s work was top notch and he wasn’t kidding.
Ryan and his guys at Jensen Mechanical recently installed a brand new Carrier Infinity Heating and Cooling system. The new system replaced an aging furnace original to the house, 30 years, and added A\C when we didn’t have it before. The entire process from start to finish couldn’t have went smoother. Ryan did an excellent job in listening to what I wanted and gave excellent guidance as to the technical details of what I wanted, as well as, talked me out of something I thought I wanted but didn’t need. He is extremely responsive and has an attention to detail that very few people have.
The quality of the installation was top notch. Ryan’s guys are just excellent at what they do. The sheet metal work was superb and just looking at the system now that it’s all finished is almost too good to be true. I look forward to seeing my before and after photos on his website.
We went through 5 bids and in the end Jensen Mechanical had the best combination of price vs. deliverability.
FWIW, we installed Carriers top of the line, ultra high efficiency, modulating gas furnace with a 2-​stage 17-​SEER A\C including a dual zoning system for our upstairs and downstairs. This included a lot of work sealing our return air ducts and building new supply ducts. Again, the sheet metal work by Ryan’s sheet metal guy was amazing.

I have been using Jensen Mechanical for 5 years and have always had excellent customer service. Ryan is honest and always gets the job done! Highly recommended!

We had some duct work done and were referred from my family to Ryan Jensen and thank goodness we did. Ryan and his team of experts were kind, courteous and professional in EVERY aspect of the job — from the initial assessment, work performed to follow up efforts to ensure everything is working properly. There is NO reason why Ryan Jensen and his team shouldn’t get 5 stars. Plain and simple, the one stop shop for your HVAC needs in the TriValley.

Woke up on a cold Saturday morning, with no heat. Made a few calls and got a referral to Ryan Jensen from my plumber. He was here within 2 hours of my call and got the job done in less than 30 minutes. Ryan took the time to give me a detailed explanation of the problem and fix. The «after hours» service rate was less than I would have expected to pay for a normal business hours rate.
When the time calls to replace the heating system, I’m calling Jensen.

We scheduled a tune up call earlier this year after a neighbor recommended this company. Ryan arrive on time and conducted a very thorough inspection and tune up. He did a great job explaining all of the issues with our antiquated furnace and A/​C unit. Everything is still humming along, but we will be sure to call Jensen when the system reaches the end of its useful lifespan.

Wow – where to start with this company. Our HVAC system was at least 22 yrs old and we figured we should get a new, more energy efficient system so we interviewed 4 different companies and Ryan was the only one who went up to check the duct work that day. His price was good and he had great reviews so we chose him.
Everything went as planned and the crew was fantastic. Our attic entrance is in our main clothes closet and they taped that off to protect our clothing in case something were to fall. Nice touch. Everyone was pleasant, respectful and attended to the job– no fooling around for these guys! Ryan had found that our main entrance tube to the duct tubes was detached so we were hoping that once it was reattached, our master bedroom, which seemed to get very little air and heat, would now get the right amount of flow.
The system runs great but we still had the problem with very little flow in our bedroom.
Ryan came out to look things over again and decided we needed some other work so off to plan B we went, keeping our fingers crossed. On the day of repair, Chris noticed that there were two more detached ducts and they fed our bedroom. Seems that all these years, we had been heating and cooling our attic!
Our problem has been solved! Our bedroom is nice and cool tonight as I type this up.
Wish we had found Ryan many years ago. The other well known HVAC team in Antioch had never found a reason for this flow problem and they did go up into the attic.
We recommend this company completely. We are grateful that they kept working with us to find a solution to our problem. Thanks Ryan, Chris and all the others who helped make this job a success!

STAY AWAY! Sneaky and dishonest! We hired Jensen Mechanical to install an AC system in our home. Their bid wasn’t the cheapest, but the owner seemed trustworthy, at least initially. He turned out to be a total cheat and the job was a disaster.
It took a month to finish instead of the 3 days we were told it would be, the owner completely screwed up getting the proper permits with the city, lied to us repeatedly saying everything was in order, dragged his feet fixing his paperwork problems, and then argued with the inspector’s safety requirement to bolt the AC unit into our roof beams. After refusing to comply and causing even more delays by trying (hiring a consultant) and failing to convince the inspector that the bolt the unit into the roof was unnecessary, he crew ultimately «faked» bolting the unit down to pass the final inspection from the City.
Throughout the whole mess, the owner, Ryan Jensen, refused to actually take responsibility for his mismanagement, although he sure could run his mouth with excuses and blaming other people for things that he did wrong.
We didn’t know the full extent of the lies until we checked this «bolting» after the final inspection. The bolts did go into the wooden AC unit base, but were too short to go all the way through the roof surface and into the roof beams, which is what the inspector had stipulated. (A photo is attached.) Their plan was probably for us to never find out — but one of his crew admitted that «the bolts are only for show» — while he stood in front of our front-​door home security camera!
Now we have a project that is not up to permit standards and serious concerns about what other shortcuts were taken during the install. Is the wiring safe? Were proper materials used?. What Ryan Jensen did was outright FRAUD of a private consumer and to a governmental authority. He has been contacted by our attorney, but has not bothered to reply. Perhaps he is too busy cutting corners and defrauding his next customer.
We have video and photo evidence to support our claims, and we will be filing complaints with the CA licensing board, with the Better Business Bureau, seeking remedy with his bond company, filing for actual and punitive damages in court, etc.
If Jensen Mechanical was this brazen about lying to the authorities and taking the cheap way out in our case, what other undiscovered shortcuts have they have taken on past jobs, and what will they try to sneak past you if you hire them?

These 100+ degree days has me thanking my lucky starts we have an excellent AC in our house. Ryan is very trustworthy, professional, knowledgeable, prompt and helpful. He provided different rebates we could take advantage of and gave great advice when we were trying to select the right HVAC for our house. Ryan is responsive and reliable. We love him and recommend him to all our friends.

Highly recommend this company. Attention to detail all the way around and great workers, too. Glad we are able to stay cool in this horrible heat! :-)

I can’t say enough about Ryan Jensen of Jensen Mechanical, as well as his assistant, Chris. After experiencing one of those nightmare home projects you hear about constantly, with workers who talked a good talk but did me more harm than good with their complete lack of care for my home and dishonesty, I only wish Ryan handled more than solely heating and A/​C! I would trust him with anything. He was my only point of sanity through an insane nightmare. He is professional, courteous, and was the only aspect of this larger job that went perfectly.
Replacing two small wall furnaces with new central heating throughout a 50-​year house is no small feat. I love the system he installed, the way he installed it, and his reliable and trustworthy way of approaching his work. I would recommend Ryan and his company to anyone. To use anyone else would be a huge loss. Thank you for everything, Ryan!

There are simply NOT enough stars to accurately leave my Review. Ive managed my own property for over 35 years & Ryan Jensen is the most knowledgable HVAC contractor I’ve ever met, my two units have floor heaters that are over 60 years old. He’s Honest & Fair too. The kind of guy you feel confident recommending to friends and family. ! You can call Ryan and not have to deal with that Contractor Anxiety. that you get when you know you need a specialist, and that’s worth everything.

At the recommendation of a friend, we had Ryan Jensen come out and look at our system. We have done an addition to the house and our A/​C wasn’t keeping up with the heat. Our son also has serious allergies to pollen and often gets up at night, with puffy eyes, runny nose and unable to sleep. Ryan recommended a Carrier Infinity system for us that would filter out the dust and pollen and an ActivTech unit to purify the air in our home ²⁴⁄₇.
The very first morning the system had been running all night, our son got up without any allergic symptoms at all. Now that we’ve had the system for about a week, I’ve noticed a difference in how my eyes feel less gritty with my contacts without all of the dust floating around. Our 20 year old furnace was about 65% efficient, and filtered practically nothing. This Infinity is at 97% and filters practically everything!
Our son hasn’t had to take his antihistamines at night since you installed our ActivTech System. Great Installation Chris and Joe! You impressed my husband with your metal work, job site management and your work ethic.
Thank you Jensen Mechanical for improving our life by improving the air quality in our home everyday, all day.
PS. I love my toe kick registers in the kitchen, very cool… worth the extra cost.

Jensen Mechanical saved our lives. Ryan came out to do a service on our home HVAC system. During his inspection of our furnace he found a 13″ by 6″ crack in the heat exchanger that had been filling our home with Carbon Monoxide (CO) and actually had been giving our 17 y/​o son unexplained migraines and vertigo. I had no idea this was even possible. Ryan showed us the symptomatic smoke staining by the vents throughout our home and told me that the furnace «blow by» and CO had been setting off my smoke alarms at night. I had thought it was just dust being blown around. It wasn’t just dust.
What more is there to say. It’s not just Firemen that save lives, it’s professionals like Ryan Jensen too.

Just wanted to post a quick note on Jensen Mechanical. My Air Conditioner was not getting as cold as it should be so I called Jensen Mechanical to schedule an appointment as soon as possible as it was going to be getting really hot that week. They fit me into the schedule that day at 7pm which was amazing. Both Jennifer, who helped me make the appointment, and Ryan who came to check out my A/​C were amazing.
Ryan went above and beyond what I had hoped for and was cool enough to explain what was going on every step of the way.
I would highly recommend Jensen Mechanical for any HVAC service or install needs.

The technician arrived on time and was very professional. He tested the various components of my system and was able to determine that it was a bad capacitor and replaced it on the spot. He also answered all of my questions about how my system worked and suggested a few things that could save me money in the future.
I would recommend them to my friends and use them again in the future.
