Sam is amazing. He was hired on to work on putting in a new hvac unit at a home in Hillsborough that I assist with managing. He was friendly and available. His work was very thorough and from the beginning to the end, he walked us through to make sure we understood everything that was going on. Whenever the owners of the house needed him, he would schedule time to come out and look at the a/c or heater even after the installation was complete. He wanted to make sure that we understood everything he was doing and it was very much appreciated.

I would easily recommend Sam for any job, he is reasonable and fair with his pricing but best of all, he is easy to work with.

Had a 32 year old furnace with a fan motor that went out one night. I was referred to Cal- State HVAC by a repair company who did not have the parts to fix such an old furnace. Samir, the owner, called me back very quickly and we set an appointment for the next day at 6:30 pm. He was running late from his earlier job, but rather than leaving me waiting he called at 6:20 (before our appointment time) to say that it would be 7:30 instead.

He arrived at 7:30 exactly, true to his word. He gave me an incredibly fair price, clearly explained what needed to be done, told me about some other options and exactly how much those would cost. There was no pressure or hidden fees at all. He even left and gave my husband and I time to discuss the work before we signed anything. He said he could start the work in 2 days at 8am.

Again, true to his word he was right on time with his crew. He did a great job in a timely manner and cleaned up thoroughly. We will definitely call him again for any future heating and AC needs.

I contacted Cal State HVAC this morning for help with a broken water heater.

Alex and Samier quickly arrived with the new water heater and an excellent job on the installation.

Both Alex and Samier are very professional, fair and trustworthy. They are also nice guys!

I will gladly call on them again should I need their help.
