We are delighted with the work from Vargas HVAC. They installed a mini-split AC in our garage and the work was exceptional. They were professional, punctual, and took the time to help us really understand the best option for our home and budget. They answered our many questions, walked us through the process and coordinated the permit requirements. We will definitely use them again. Thank you!
