I highly recommend Mike and Supreme Mechanical for your HVAC issues.

Mike was quick to respond, scheduled my appointment the next day, confirmed, notified and showed up on time. He had the parts on hand (capacitors) to get my unit back up and running. Did a thorough system check including adjusting the gas pressure, refrigerant levels and checking for carbon monoxide from the heater. He explained everything he was doing clearly, he obviously knows what he’s doing. His pricing is competitive and the service is excellent. I will definitely be referring him to my friends and family.

Supreme Mechanical did an excellent job replacing my old mini-split when it went on the fritz. Mike explained the process clearly and answered all my questions. Mike and Jose were punctual, professional, and extremely knowledgeable. The installation was smooth and they left my place spotless afterwards. I was especially impressed with their attention to detail and how Mike took the time to ensure everything was installed correctly and functioning properly.

The new system is working perfectly. It’s rare to find a company that combines great customer service with top-notch workmanship. I will definitely use them again for any future heating or cooling needs.

Highly recommend!

We are so glad we found Mike. He is professional, courteous, and punctual. He installed a Bosch heat pump system for us after listening carefully to us to figure out what we needed, and made some tweaks to our duct system to make everything run efficiently. There were no delays, he performed the work on the days he said he was going to. We love the system. Mike is knowledgeable about heat pumps and clearly passionate about it, too. When the system was unpacked he admired it like you would a nice new car. For us it was just an HVAC, but he saw a beautiful piece of engineering. I liked that. The system worked flawlessly to keep us cool during the heat wave and has been working great heating up the place now that it’s gotten colder. Yaay for Mike!
