I…read morecalled Millers to come out to give me a quote on replacing the AC unit as Eagle Air had quoted us at 30k to replace and install a new AC unit. Alan a manager came out to inspect and give us options on how we can proceed in replacing our current AC. He was incredibly well informed and very knowledgable in explaining what our best options were. He called the office on the spot to set up an appointment for a service tech to come out and see if we could first fix the AC before doing a total replacement. Alan offered to bring us a window AC unit due to me being in my late 3rd trimester to make sure I am comfortable in the mean time. Sonny the service tech came out and found the problem with the AC unit in record time! We had a previous company come out and told us it was the compressor and quoted us at 7k to replace. It was in fact the capacitor that was not working. Sonny fixed the issue incredibly fast and now we have perfect working AC just in time for the heatwave. He was extremely professional and helpful in answering all of our questions. 10/10 I could rave all day about how wonderful Alan and Sonny were in helping fix our AC issue in a timely manner with out breaking our wallets with a baby on the way. I will be only using Millers Air for life and will let all my family and friends know this is the only option for AC services they'll ever need. Alan and Sonny I whole heartedly thank you 1000x over for your incredible service and kindness!

After the previous company failed to complete our Furnace repair we asked our SIL for a…read morerecommendation. Miller's AC & Heating was my first call, I requested they repair our Dual Heating System. They had an appointment the very next day. Tony arrived early. He immediately understood the problem with the dual system. He skillfully set it up so it would work while he ordered the part required. He explained everything, was super friendly, quick, and efficient. We are excited to have heat while we wait for our part to arrive and be installed. Toni was a pleasure to work with, and we look forward to a fully functional Heating System. Sonny finished the job today...he was a pleasure to work with. Our builder did not mark any of the components, fortunately he solved the puzzle, and we now have a fully functioning Dual Heating System.

To the owner's credit, he took that feedback seriously and made a genuine effort to make things right. Fast forward a year later, I had them out for regular maintenance and the experience was completely different--in a good way. Scheduling was smooth, communication was clear, and the technician showed up on time, was professional, and did thorough, quality work. The system was checked carefully and everything was explained in a way that made sense. I really respect a business that listens to feedback and improves. While the initial install had its challenges, the follow-up service showed real accountability and commitment to customers. Based on this most recent experience, I'm comfortable continuing to use them for maintenance and would recommend them, especially knowing they stand behind their work.

They hit another home run when Isaiah and Monty were assigned to a plumbing issue at my house. It was a hectic week to start, topped off with a backed up toilet that started to overflow. After I turned off the toilet and used a plunger and some elbow grease to fight back the overflow, I knew I needed a professional opinion. Turns out, Jazz not only fixed a huge backup of sewage, fixing the immediate issue; they did it with such professionalism that I was really impressed. Monty and Isaiah were a great team. Special shout out to their non-pushy approach. I really appreciated the speed, efficiency, professionalism and honesty that these associates demonstrated. The folks on the phone, such as Mario and Adrian/AJ, are also fantastic and really made the process easy end-to-end. Well done, Jazz. That was excellent overall value and the highest-quality service I could ever ask for.

This was literally about an eight month ordeal due to the incompetence of "Tech Clean" The company…read morethat was administering the federal rebates for California as I needed the unit to actually be installed before I could claim it on my taxes, so I literally had to file an extension because tech clean was not on the ball.

I voiced my concern and they were understanding and apologetic for the lack of communication. They processed a refund for the full amount.

I sent out quotes and while one company (named after a music genre) replied with an appointment for one week LATER (no, just no: I'm not going to survive with no AC for 7 days with temps from the high 80s to high 100s) so I sat back to wait for other quotes with a closer appointment within a day or two. Jay from JE Moore Air Conditioning reached out to me and asked about my AC's symptoms (AC turns on, fan turns on, condenser turns on - yes, yes, no). Jay mentioned that my AC's capacitors may have died and was able to squeeze me in between his scheduled jobs THE DAY OF my quote inquiry to take a look. Note: your mileage may vary depending on YOUR AC symptoms and the jobs that Jay has scheduled for the day. My central air was fixed (failed capacitors was the culprit), a couple Benjamins from my wallet migrated successfully over to Jay, and I'm good to go. Cash preferred but checks accepted at a higher premium (I paid cash). THANKS, Jay!
