Just had another very professional and great visit by Mike. Strongly recommend his services. He is professional, courteous, and knows his stuff. Doesn’t pressure you to do anything you don’t want and ensures you have the info you need. Has always addressed the issues that come up promptly. Even his maintenance services are better and more comprehensive than other larger companies. He quickly identified an issue that was causing flooding from my AC unit which was caused by failure of the prior technicians I had hired to do proper maintenance. He’s come and repaired a bunch of stuff for me. Again, a strong recommend.

I called Mike after finding his company on Google. They had many great reviews so I called them . Mike came out and repaired our old system, which was in it's last legs. . We decided to replace the system. They gave us a fair estimate, and installed a new HVAC.. This company is professional.., fair priced, and thorough in their work . l highly recommend them.

Mike is extremely professional and obviously cares a great deal about high quality installation. I upgraded my entire HVAC system through him and am very pleased with how he handled our very hectic schedule to get us up and running. The new system looking much better than the mickey moused install that was there previously

Fantastic service. Mike was great. I have an old school Cozy wall heater from the 70’s and he knew what to do. Will definitely be reaching out again for any heating (or cooling) needs!!

Thank you Mike for supplying the type of Customer Service that seems to be long forgotten. My experience with Supreme Mechanical Heating and Air Conditioning was excellent, not just good, I mean excellent. Between the professionalism that was displayed from entering my home to address my issues to the final solution I could not be more pleased. The issue was resolved in a quick and precise manner, Mike had what he needed to address the issue, as well as leaving my home spotless after the work was completed. If you are looking for a good reliable knowledgeable honest AC/Heater service call Mike at Supreme Mechanical Heating & Air Conditioning !!!!!!!!! I promise you will be as pleased as I am.

The best HVAC company I have ever worked with. I called on a Saturday night at 6 pm and Mike came to look at my AC which had stopped. He was able to do a fix to get tied me over. My 2007 AC needed replacing. So did the rest of my HVAC system in my attic from 1989. It had been limping along. Mike gave me great quotes and suggested I replace the ductwork since it was from 1989 and had been patched many times. So thankful I listened to Mike. The ducts were rotted and had holes we didn’t see. I was breathing in attic dust. Thanks to Mike i have great new systems and clean air. He was so responsive and so helpful.Highly recommend and won’t use anyone else.

Hands down the best and most honest AC service company in LA!I’ve been renting my place for the past 4 years, and every summer my landlord sends an AC company to service the unit. Let me tell you—it gets insanely hot upstairs. I’ve had to run the AC for at least 15 hours a day and still end up sweating.This year, my landlord finally brought in a different company—and thank God for that, because that’s when I met Mike, the technician. He’s the only tech in four years who actually asked me where the air condenser was located. I had no idea what he meant, because every other tech just showed up, swapped the filter, and left.Not Mike. He took his time, went up to the roof, and fully serviced the air condenser—something that should have been done every single year but clearly wasn’t. The difference in performance was night and day.Mike was honest, thorough, and actually cared about doing the job right. I can’t recommend this company enough, and I will definitely be requesting Mike for future services.Thank you, Mike! You seriously saved my summer.

I called Mike this morning and he made sure to fit me in as soon as he could. He kept in touch with me throughout the morning to let me know exactly what time he would be arriving at my place.As soon as he walked in, he immediately put shoe covers on his shoes and carefully started examining the thermostat as well as the AC unit. Cleaned everything thoroughly, made sure it was working, and was on his way in under an hour. He explained to me the problem and how to prevent it.Highly recommend.

We have a difficult set up with our unit on the roof. Mike was willing to figure out a way to work with us and had our unit up and running in no time. He thoroughly inspected each aspect of our unit as well to make sure there wasn't any other hitches we'd run into.Throughout our whole interaction, Mike was very professional and willing to provide us with any information on how to maintain everything properly, as well as realistic solutions we could implement going forward.We'll definitely be looking to them again in the future!

When my AC unit suddenly stopped working, I was referred to Mike through a good friend of mine. It was truly a pleasure working with Mike, and I would certainly recommend him for others in need of AC service/replacement jobs.Mike knows what he's doing and it's obvious from the start. He immediately identified what happened to our unit/why it broken and gave us several options. Our unit was old (installed in 2006) and he said he could fix it, but this would come with certain issues given the dated nature of the unit, or replace it, provided that we were financially able to do the latter. We went through the benefits and drawbacks of both options and ultimately opted to replace the unit. Mike then provided us with a few options and quotes in timely fashion, promptly getting our project onto his calendar and in-motion.Communicating with Mike is a breeze. He always answers the phone and reaches out/follows up as promised. He is timely, arriving when he says he is going to arrive, and happy to give you the time you need to answer all questions to make sure you make the decision that's best for you. He sets clear expectations and he follows through with them every time, without fail. This, to me, is always a contractor's greatest asset and is one of the reasons I'd definitely use Mikey again if we have any other HVAC-related issues.Beyond suggesting a great unit, Mike also noticed some other shortcomings in our AC system when preparing to install the new unit and gave some suggestions to ensure the new unit's optimal functioning. His suggestion would up being great and our home overall is much more comfortable than before.In short: Mike is great! :) I'd be happy to use him again and to recommend him to others.

They were very nice and Professional.

Supreme Mechanical was Great! Mike showed up promptly as scheduled, neat, clean and knowledgeable. I received a detailed explanation of the work completed and very good preventive advice. I would recommend again and again. Extremely Satisfied!Update! I have a rental property in Canyon Country and the AC went out. It was only 90* today! These are great tenants and I wanted to get the AC working ASAP. Mike was able to come out the same day, diagnose the problem, pick up the part and have the AC running again later the same day. Thanks again Mike!

Mike did a terrific job -- fast, detail-oriented, reasonably priced, and thorough. It's 95 degrees outside right now, and inside it's 72, and I couldn't be happier.
