The Diamond Air team is truly exceptional. I purchased a full HVAC system from them 5 years ago, and when my heater suddenly stopped working, they promptly arrived the next business day. They expertly diagnosed the issue, identifying a faulty gas valve, quickly obtained the necessary part, and installed it the same day. The best part was that they didn't charge me a single penny for the repair, which was completely unexpected and greatly appreciated. Diamond Air has proven to be an outstanding service provider.
We are extremely satisfied with our choice to use Diamond Air Services. From start to finish, the entire experience was exceptional. Their level of professionalism, attention to detail, and quality of work far exceeded our expectations. The technicians were knowledgeable, punctual, and took the time to thoroughly explain their actions. It's clear they take great pride in their work, and the final installation/repair reflects that. They ensured everything was completed correctly and left the area clean and organized.
Howie and his team did an excellent job installing our new heater and removing the old one. The entire process, from consultation to installation to city inspection, was completed quickly and efficiently. The price was very reasonable, and the service and communication were clear and easy throughout. The team was professional, clean, and respectful of our home, ensuring everything was tidy when the job was done. We also appreciated the helpful recommendations they provided. We highly recommend Howie and his team.
I contacted this company to have my AC unit inspected because my lower unit had stopped cooling, and I'm so glad I did. The response time was impressively quick from the moment I reached out. Howie was friendly, professional, and truly knowledgeable. What I valued most was his honesty - he walked me through the diagnostic findings, explained everything in plain language, and did not try to sell me on unnecessary repairs or parts. This level of transparency is rare and refreshing. The pricing was fair, with no surprise charges or hidden fees, and he got the job done right the first time. If you're looking for an AC company you can trust, this is the one to call. I've already recommended them to my neighbors.
We recently needed a complete air duct replacement for our HVAC system, and Baran and Oscar did an amazing job. They were professional and highly knowledgeable, completing the job in half a day. We were impressed by their professionalism and the steps they took to keep our home clean during and after the work was done. We would highly recommend Diamond Air for any heating or AC needs.
