We knew our HVAC was aging out so wanted to get it replaced while we could still negotiate price and before horrid temps set in. We checked around and opted for Vanguard. I ran their bid proposal through our HVAC repairman son-in-law in Az. He agreed both the price and equipment quality were very good. Enrique and Fabian worked into late at night for two days to completely replace our entire HVAC. Following completion Enrique made two subsequent visits to assure equipment was functioning properly under varied weather conditions. He was very honest and thorough. We are glad we went with Vanguard and are pleased with the results.
