Best HVAC System Repair in Oakland CA

Prompt, and thorough. He discovered a problem that that the last service company did not notice, and explained it to me very well.

I called Supreme Heating and Plumbing during the middle of a heat wave (yes, you read that right--a heat wave...in Oakland!) when my AC/house fan was not working (90 degree temperatures on the top third floor of an apartment--no fun without AC!).

I had already called approximately ten other companies that day, understandably they were all booked and no one had any availability sooner than three days later. I talked to Amili from Supreme at noon and he was able to schedule a time to come out at 6pm. He was one of the few companies who could schedule an ACTUAL time instead of a window (literally one company had told me they could schedule for between noon-6pm where I would just need to wait around all day for them to show up) and also one of the few companies who would come out during evening hours without charging more. As a person who works standard office hours and commutes from Oakland to SF every day, this was REALLY appreciated.

Amili came out and arrived right on time. He was professional, friendly, and very informative. He crawled up to my sweltering attic to investigate, fiddled around with my thermostat, and quickly diagnosed the problem. Although he did not have the parts to fix the problem right then (the thermostat itself was faulty and had to be replaced), he explained exactly how to replace the thermostat and even how to re-wire the new one if the back had to be replaced. This turned out to be extremely useful because the new thermostat did indeed have a different backing and required re-wiring, which I have never done before.

I was able to head to Home Depot, buy the replacement part, rewire and install the new thermostat on my own following Amili's instructions, and get the house fan up and running!

Amili and Supreme Heating and Cooling are at the top of my list now for all my needs.

We've been using Jazz for various services over the past 4+ years and we've been so happy with their quality of work, reliability, and customer service. Every single technician (HVAC, plumbing, etc) is like the nicest person ever! Jazz installed a new Lenox AC & Furnace with tri-zoning in our 2 story home. They have also installed a new water heater and an earthquake shutoff valve for our gas meter. We also use their annual check-ups program for both our furnace and AC. We can't recommend both Jazz and Boom enough.

1st review ever, but had to write one because Damon deserves 5 stars alone for outstanding customer service.
Long story short called a bunch of services to ask if they had technician avail to unclog a sink drain. Everyone including Damon didn't seem to have anyone available, however Damon calls me back with a different company I should try. And low and behold I have a technician coming out today!
So thank you Damon! If I have any future problems I will definitely call you first.

Miguel arrived and promptly fixed the kitchen sink. Polite, professional, and competent! I will use Magic Plumbing again.
