 Trustindex verifies that the original source of the review is Google. The technician that came to service and fix my cooling system, was very knowledgeable in what he was doing, he look for the issue and located the problem very quickly. Gave me an assessment, explained what the problem was, and what needed to be replaced to get the system back up and running. Outstanding tech I might add.

 Trustindex verifies that the original source of the review is Google. Listen. These guys are genuinely here to help their customers. Called on a day when I had an emergency and they were booked up. They made time for us. Simon talked us through every step and made sure we understood how to maintain our HVAC system properly. They are now our go-to! Don’t hesitate. Call.

 Trustindex verifies that the original source of the review is Google. I can't recommend Hernandez Heating & Cooling enough. Simmon came out for an estimate and was a standout compared to other companies. He was punctual, answered all my technical questions, and actually identified a critical safety risk that every other vendor had completely overlooked. He provided his estimates the same day and was proactive about identifying all available rebates to help with the costs. If you want a team that is thorough, safe, and professional, look no further.
