Oscar was able to help us so fast during the recent heat wave. Our air conditioner had been having a multitude of problems and he was able to clearly explain the issues he was finding, solved them, and stayed after to make sure the solution actually worked. So grateful for Oscar’s help!

I’m so glad we decided to go with a smaller local company instead of one of the big HVAC corporations. Oscar at AMP HVAC was honest, responsive, and genuinely cared about helping us rather than trying to sell us things we didn’t need.
From the beginning, communication was great, he showed up when he said he would, explained everything clearly, and made the whole process stress-free. The quality of the work was excellent, and it’s obvious he takes pride in what he does.
We’re extremely happy with the results and will definitely be calling AMP HVAC for any future heating and air conditioning needs. Highly recommend!

Oscar was great to work with. Explained everything used photos to highlight his work. They (an associate worked with him) were very careful to cleanup and vacuum the area they worked on. I recommend him without reservation.
