Best Furnace Repair in Oakland CA

Carlos was on time, efficient at resolving any issues, knowledgeable and easy to work with.

We had a heat pump installed. We are very happy with the service. They were reliable, very professional, and left the work areas cleaner than they found them. They also respond quickly to questions and made the process very easy.

These guys leave multiple flyers all around my house every week. It's a mess! Asked them to stop they said no. I am so tired of cleaning up their litter!

Mike installed a new Williams Top Vent wall Furnace. He did a great job. He arrived on time. He knew exactly what to do. Install the Furnace in a timely manner, Left no mess, and at a very fare price. The next time I need any pluming or heating work to be done I will call Diamond Plumbing and Heating. That's for sure.

Friendly and professional! Offered advice while expertly installing our hot water heater. He even corrected a mistake made by the original installers.

These guys can fix almost any plumbing problem, if not all of them. Theyre quick, affordable and very knowledgeable. They are the go to for any plumbing needs.

Victor, owner operator of Gladiator Rooter and Plumbing handled to provide us a brand new main water line (copper L grade pipe) to our house on June 30th., 2020. His price quote compared to other companies was most welcoming. He understood the project so quickly and finished the project in one day. I highly recommend to anyone, if you're looking for fixing any issues related to plumbing.

The plumbing technician, Issacc,was on time, friendly, polite and extremely knowledgeable .
I highly recommend him.

These guys are the BEST! I've worked with several outfits over the years but none that compare to Supreme Plumbing and Heating!!
