Mike, Dan and the crew did a fantastic job! Even though my installation was odd and quite difficult to complete (furnace in the crawl space), they did a fantastic job! Everything was cleanly installed and not a sign of them being on site except for that sweet cool air. I would highly recommend their service.

I’ve used Miller’s at my home and rental units for a number of years. They are quick to respond and seem honest in their repair assessments. I recently had Ori out to my condo in Pleasanton and he was very knowledgeable and professional in his repair skills. Larry, you’re not paying him enough!!!

My AC units compressor stopped working properly, the motor would run, but not the blades. Called Millers 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.

We had our AC unit inspected for a routine maintenance before the hot summer arrived. Ori D. responded and was very professional, explained and showed me everything he was testing and answered all of my questions. It turned out all I needed was a new capacitor and that all of my other system was functioning properly. He was very respectful and polite, I would highly recommend Millers for any HVAC issues.

Best interaction Ive ever had with an HVAC company. No phone systems, all personable folk that are good at their jobs!

Ore was a friendly and knowledgeable guy who helped me understand what I was dealing with. A great employee for your company.I highly recommend your company because of him.👏👏

I have used Millers A/C and Heating throughout the last 30 years. The service Ive received has consistently been top notch and professional. Larry Miller is the first person I call when I have heating, water heater, and A/C needs. Millers is the best!

Larry is the BEST. Took time (even in his day off) to service my A/C! Heading into triple digit heat with no A/C was a horrible feeling. Super thankful for Larry(Super friendly and professional too). Highly recommend

I cant say thank you enough to Mike who came out on the hottest day of the month to work on my AC on the rooftop. Fast repair, on time, great value, quality work and great follow-up work. I will strongly recommend to friends and relatives.Millers AC/Heating I am proud of your company.

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. 😊

Accurate and efficient diagnosis with prompt repairs on heater, air conditioning and thermostat issues

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.

I am very pleased with the two air conditioning and heating units I have purchased from Millers . I also recently received timely, excellent and professional follow-up service from service technician Ori Delgado. I highly recommend Millers Air Conditioning & Heating.Ken Z

Great service by knowledgeable people. Also they are fare and have honest pricing. The installed our whole system and has maintained it and serviced it a few times. They do an amazing job. I especially appreciated the speed of time they got me in when I had an AC emergency in the 💯 degree weather. I would recommend them to anyone who needs HVAC service.

Fantastic company and equipment. Probably why they have been in business for more thqn 60 years.Millers recently installed a high efficiency Bryant heating and air conditioner in our house. I am impressed with the final product. They completed the job fast and expertly. Their guys were in and out of here with little to no mess and they hauled away all of the old equipment and disposed of it. This unit is fantastic and half the noise of the old one. We actually added in a few accessories such as a tray for the easy changing of the filter, an air purifier, and a WIFI thermostat. What a great convenience to be able to turn on the heat before we get home and to check it when out of town. The air in the house smells cleaner too. Worth adding in the extras! Thanks again guys.

I really highly recommend . The techs are knowledgeable and a pleasure to work with. I have used other HVAC guys in the past but these guys beat them hands down. Give them a call, you won’t be sorry. Would highly recommend their services.

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 Millers!

I got in touch with Miller’s due to my 34-year-old dual AC/Heating unit giving me problems. Larry Miller came out same day to diagnose the issue, but of course the unit worked perfectly while he was there. Larry spent over an hour troubleshooting and we ended the appointment with a probable fix and directions to monitor the issue and report back on my findings. Although the unit did work better after Larry’s troubleshooting, the issue still occurred, but less frequently. After consulting with Larry, I made the decision to replace the entire unit as the existing unit was old and most likely in need of replacement very shortly.A week later I had a brand new unit and my AC is pumping without issue. Mike LeGate (highly recommended) worked his butt off getting the unit installed and up and running. He went above and beyond on the service side, even offering to get us a portable AC unit from his shop while he worked so we could have AC running in the house.Bottom line, DO NOT LOOK ANYWHERE ELSE FOR YOUR HVAC NEEDS!!! Miller’s is extremely fair, honest and knowledgeable. There is no need to look elsewhere!Thank you Mike and Larry!!!

The quality of service and professionalism provided by technicians from Millers is second to none, absolutely outstanding. Larry Miller is an expert with over 40 years of experience. If you are experiencing a HVAC issue, do not hesitate to call Millers, they will fix the problem and treat you right!

Very thorough investigation of my problem by Kevin. Explained what he was doing and put in the extra effort to check hard to get at places.

I called Millers because of our past experience with them. Ori Delgado was the tech who made the service call to assess our cooling system. He was professional and friendly, but more importantly he was very thorough and had some good and effective recommendations.

It took three calls over the course of two weeks to get someone to come take a look at my unit. The service technician was nice and informative. He told me the unit needed to be replaced. I called three more times throughout the following week to get a status update on my new unit. I never once heard from them. I will never use Millers ever again.

Got a heater issue which cant be identified by another company, so called Millers for help. Kevin come to us and spend half hour to test each part, then find out the root cause. One week later he come back again with all replacements shipping arrived. Replace the broken ones and give all heater cooler fan a test to make sure them work well. Kevin did awesome work, while answered a lot of my questions. Thank you!

Well, after 4 days with no A/C in this merciless heat, Millers Air Conditioning & Heating came to our rescue. Kevin arrived according to schedule, actually I was pleasantly surprised he was a little early. He got information quickly, then did his thing. He worked his magic and pretty much knew what was wrong within 15 minutes. He completed the repair and got us back up and running. Thank you Kevin and Millers Air Conditioning & Heating!

Kevin from Millers came out and helped us turn an ancient zone heating and AC setup into something usable and installed a Nest Thermostat for us. Kevin was great and I would not hesitate to call Millers again.

Best HVAC company out ! They did a wonderful job at my house . can’t thank them enough. Thanks again Millers !

Millers has supported our home for many years.There was a PG&E power surge that damaged our HVAC. Mike and the Miller team quickly came out to fix. Our controller board was cooked. The board was non-standard so they put in a temporary board while the exact model was rushed from the factory.Then there is the rat story a year later. The HVAC was intermediately turning off. Millers came out. A transformer was blowing out. After they replaced that they added a pop-up fuse to protect the transformer, nice commitment to quality.Then the root cause was identified by Millers. In a very remote spot in our 100 year old crawl space they determined that a rat had eaten the insulation off of the control causing periodic shorts.The crawl space was sealed but a couple of years later it happened again. During peak summer heat Mike and Millers got the air condition running on a Friday evening. I then replaced the control wires with ones that were metal cladded to provide protection against rats should they get back in the crawl space.Millers then came out on Labor Day and replaced the fuse that had blown before the new conduit was installed.Their performance has been excellent.

Very pleased.

On Tuesday, I called for an appt., and was pleasantly surprised they had a technician available to arrive on Thursday between 10:30-12:30. Ori arrived around 10:30 and completed the work needed within an hour. He was very knowledgeable and friendly.

Wonderful and fast service, Mike was courteous, I am a disabled veteran and pleased with the way Mike handeled our problem. We are grateful, satisfied with Millers co.

Miller’s replaced my air conditioner in one day with a better unit, more efficient, great price could not be happier. A company you can certainly trust.

This company is awesome, I trust them with all of my heating and air conditioning needs. If you want it done right go with Millers

He never finished the service.

Over the last few weeks, the air condition system in my daughters home in Livermore has failed---it is no surprise it is near 20 years old---Miller Co has repaired it very quickly in the past but the old unit is DOA----A few weeks ago, I had JIM WILLIS come out and do a new unit replace and design for the house--Jim was absolutely top drawer in presenting a design and quote that I accepted---Install was promised in about 10 days----Today, as PROMISED, Miller technician, DAVE MAYHEW arrived with new unit and his tools and expertise ready to go---over the next few hours, Dave proved he is a very competent and able tech--he installed the new unit and thermostat and it took only minutes to watch the temp go down---I commend Jim and Dave as well as Miller Co for having such excellent representatives and service---On a scale of 5 STARS I give them 10! Bob Woods, Livermore.

This is an old Livermore company that has been around forever. Larry the owner does good work.

Best a/c company in town!

Conscientious and professional with great product!
