Excellence on Every Project
Sent a message to Platinum on Sunday to fix our AC. The next morning, they called back and said they could have a technician at my house in a matter of minutes. Not even five minutes later, our guy shows up. Did some extensive testing and troubleshooting. Recharged the system and had it up and running in about an hour. Now it works better than ever. And the cost was very reasonable. Jacob (the technician) did a great job. He’s very professional and he really knows AC systems. Platinum is our first choice for HVAC repair. We’re always happy to support local businesses. Thanks

Customer
Customer service: Amazing. Communication: Amazing. Diagnosis of work: Amazing. Cost: More reasonable than others. Customer satisfaction: 5 stars. Our church experienced an AC unit that malfunctioned during one of the hottest heat waves of the Summer. A company came in and misdiagnosed the issue, giving us an astronomical repair estimate. We called around to get another opinion. Everyone we called was at least two weeks out. Several recommended Platinum. Angelo (the owner) and Orlando (the assistant?) came out the next day. They quickly identified an issue and explained the process of repairing it simply.

Customer
Last January my furnace stopped working during the middle of winter during that cold snap when it was -20 degrees. I called Angelo and he came over in the middle of the night to fix the issue. This January the same thing happened and again, Angelo and his team came over and fixed it. Every time I need something to do with hvac I call Angelo and he is on it right away. It’s always a great experience and always a great price!

Customer
Amazing company is putting it lightly… everything from the estimate to the final product being installed everything was easy, affordable, and the work is second to none scheduling and communication with the owners was amazing. very helpful and knowledgeable about the products they service. Can’t recommend this company enough

Customer

It’s rare to find a company that combines and great service with integrity, but these guys nail it! I highly recommend them to anyone looking for reliable HVAC work at a great price!
