HVAC reviews in Livermore, California

Larry and team are always fast to respond, professional and fair. I have used them for years. They helped us out with a new furnace and a/c years ago and we use them for servicing. Most recently they came out for same day service and fixed our furnace right away. I highly recommend Miller's!

Had a Full House Heat Pump and Condenser and new thermostats installed by Miller AC Recently, they did a great job. I have also used Miller AC and Heating when I had another place and the furnace stopped working the day before Thanks Giving, these guys were out and fixed the problem within hours. Special Thanks to Mike , Sabina and Nela and their boss Larry

I contacted Miller's to replace my 18 year old HVAC system and everything from the design/consultation/installation was timely and thorough. Whenever, I had a question or concern, they were answered promptly. The installers came at the promised time and the work was performed thoroughly. I also want to personally thank Mike (one of the owners) who took a hands on approach to my project to insure completeness and quality.

Miller's installed my ac/heat unit 4 years ago. They were great to deal with. Today the ac stopped working and I called. Despite this being their very busy season, they sent someone out a few hours later. A faulty part was replaced and the ac was back on before the heat of the day took hold.

I love Miller’s. I manage property and they are always prompt and considerate. My tenants love them. I personally just had them replace my heater and air conditioner. Again, they were prompt and efficient. Got the job done and you couldn’t even tell they were there. I highly recommend them!

Called Miller’s Air to service my heater and air conditioning unit and ducts. The units had not been service by the previous owners since 2015. After doing the inspection they found 2 bad condenser relays and a bad control board. All were replaced. Larry Miller and his staff are excellent and friendly. I will recommend them to all my friends and family.

Larry Miller is an honest outstanding business man. Not only is he trust worthy, but is honest and does quality work. I have been using his services for 7 years now and is the only company that I trust not to gouge me just because I am a woman. He has always looked out for us and our air conditioning and heating issues. He and his company get five stars all across the board. Thank you Larry for always taking such good care of my family and I. Yours truly Kim Sorensen. 😊

I am not a fan of these other chain HVAC companies and have opted to use Millers service for my AC needs. I had the opportunity and pleasure to have Ori come out 2x to diagnose my issue. He was very professional and very competent and knew his stuff. He completed the work and left everything very clean and tidy. Its service techs like Ori that make companies like Millers worth doing business with. Thank you Ori for the unparalleled service and professionalism during you visit. Highly recommend Ori for any service call with Miller.

My AC unit's compressor stopped working properly, the motor would run, but not the blades. Called Miller's Air Conditioning & Heating, explained my problem and was able to set up an appointment for today, to have a technician come over and check it out. Got a call from Ori, about 30 minutes before the appointment, asking me if it would be okay for him to come a little earlier. I told him not a problem, he came and to my delight not only was he able to detect the problem, but was able to fix it right away at a very reasonable price. Very happy with Ori and the Miller Company. Thank you for a job well done.

Excellent installation of A/C and Heater unit. Ned, Ed, Sergio and Michael, showed up on time and took their time in taking our old unit and installing the new one. Ned show me the new unit and explain how the city will process the permit.

I had a great experience from this local company. From my first meeting with Mike to the final day with the install crew, it just went almost TOO smoothly.
Replacing a heat and air conditioning system is a major investment and there are lots of options to consider. Mike was great at explaining how things would be installed and exactly what I would be getting. He's a patient guy. The install crew, Dan, Sean and Cameron were efficient, left the work areas clean and picked up, and took the time to explain the operation and maintenance tips.
Local company, great crew, happy customer.

Miller Installed my HVAC long time before. It was a great service and loved it. Then I referred many of my friends in my area and everyone appreciated their service.

But in the last few months, getting their support for fixes became super difficult.
One of my neighbor and friend suffered recently and finally got the service from the owner. Thank you.

Now I am struggling without AC and reached out my first and best Miller’s service.
Unfortunately I don’t have any technician available to help me till mid of next month.

I wish everyone not to have this kind of issue.
At present I don’t know how to resolve my problem.

They park their vans blocking the sidewalk. And they have been there for hours. A person in a wheelchair probably won't be able to get through and will have to go on the street.

I have been a Millers customer for almost 10 years and they never fail to impress. They recently went out of their way to solve an issue and I just can't recommend them enough.

Guy and Sergio did an excellent job installing our fans. I found that everyone I talked to in the company was professional, knowledgeable, and easy to talk to. All appointments were on time. My complements to DJ, Sergio, and Guy for working in the attic on a hot day, and we love our new fans and they are working very well. I would definitely recommend them to a friend. Thank you!

The 5-Star review is for Tony, the technician who fixed the problem with our furnace. Our furnace was installed in 2018 but had never worked properly. Tony spent the time to diagnose the issue and we finally have a furnace that works as it should.

Our furnace was not giving out enough heat and we called Miller's to send a service technician. Sonny came out the next day, quickly diagnosed the problem, made a few other checks, and fixed it. He was friendly, knowledgable, and completed the work is less than an hour. We will call Miller's again the next time we have an issue.

I enthusiastically recommend Miller’s Air Conditioning and Heating for installation and service. Having gone to four local companies first, I found a disappointing pattern of generic brief reviews of my HVAC replacement needs followed by high priced quotes on low-end models. One even suggested they could give me better pricing if I did not seek a permit. (???!!!)

Things got off to a good start when I spoke to Stephanie at Miller’s and she took the time to listen and to schedule DJ for enough time. DJ reviewed my existing system, analyzed my needs, answered my questions candidly, provided a fair quote on a better system, and replied to consequent emails promptly. I also had great interactions with a number of Miller’s employees on the installation, training, testing, and permitting including Pablo, Sergio, Tony, and Alan – really a great crew. I realize no business is PERFECT, but I would say Miller’s is as close as you are going to get for transparency, fairness, good quality reliable products, high quality workmanship, and a focus on a customer’s positive experience. Thank you everyone at Miller’s!

I’ve used Miller’s HVAC several times now, and they’ve become my go-to local HVAC company for anything related to AC repair and heating/cooling service. The first two times, Sonny came out. He’s incredibly knowledgeable and helped diagnose and fix our AC issues in our older home. He added freon, replaced a few parts, and got our system running much more efficiently.

A few months later, we hired Miller’s HVAC again for a full ductwork replacement under our house. Their three service techs were fantastic. On day one they took measurements and removed all the old ducting, and on day two they returned to install everything. They worked fast, cleaned up thoroughly, and even caught a blown fuse on our AC unit and repaired it on the spot.

The owners, DJ and Kelly, are wonderful, the communication is great, and you can tell this is a small local business that truly cares about quality and customer service. If you need AC repair, ductwork installation, or HVAC maintenance in the area, I highly recommend Miller’s HVAC. They’ve taken great care of us every time!

We had a faulty furnace with a bad inducer motor, and after a truly disappointing experience with another HVAC company (rhymes with Spaz), I found Millers — and what a difference.

From the first call, Kelly made scheduling easy and pleasant. Dominic (hope I’m spelling that right) showed up right on time, quickly diagnosed the issue, confirmed the part was in stock, drove to their warehouse to pick it up, and had our furnace fully repaired the same day.

The service was fast, professional, and priced very reasonably. I’m seriously impressed — I’ll be calling Millers again for any future HVAC needs and recommending them to everyone I know.

I’m thrilled to share my experience with Millers Air Conditioning after my recent installation of a new air conditioning unit. They were so quick to come out and give me a quote, and I was impressed that they were able to start the job right away! The team was prompt, professional, and incredibly knowledgeable, making the entire process seamless. I appreciated their attention to detail and dedication to ensuring everything was perfect before they left. It’s refreshing to work with a locally owned family business that truly cares about its customers. If you’re looking for quality service and a dependable product, I highly recommend Millers Air Conditioning!! They’ve definitely earned my trust!
