I can’t say enough great things about Omid , He came to our home to fix our air conditioning system. From start to finish, the experience was professional, efficient, and honestly just a huge relief.
They arrived on time, quickly diagnosed the issue, and had everything up and running again in no time. It was clear they really knew what they were doing — not just in HVAC work, but in general home repairs as well. In fact, this wasn’t our first time working with them. They had previously helped us with plumbing issues and even repaired a faulty faucet, and each time the quality of work was outstanding.
If you’re looking for someone trustworthy, skilled, and genuinely committed to doing a great job, I highly recommend them. We’ll definitely be calling again for any future repairs — HVAC, plumbing, or otherwise. An absolute 10/10!

I would highly recommend Jeff, the owner of Otech, and his services. I thought I was having an issue with my water heater; he came out to my house and identified that the actual issue was with a faucet. He was prompt to respond, explained the issue, and made recommendations. He was able to fit me into his schedule quickly to help me with the identified issue. His pricing was reasonable, he was trustworthy, and he took care in cleaning up the area after he was done. We will use Jeff at Otech for our future plumbing needs.

I am so thankful for Otech, I had a plumbing issue and a furnace issue in the same week and they saved me twice. The cold water cut-off under the kitchen sink and an old main cutoff valve needed to be replaced. Excellent job on both valves at a reasonable price. While the plumber was there, the furnace failed. On Friday night it was too late to buy the new part, but Monday he came right back and fixed the furnace. And it is better than ever, also at a reasonable price. If you find your self without heat or leaking pipes, and you don't know who to trust, I can only suggest you call Otech for your own peace of mind.
