I have a home in Huntington Beach that had an existing furnace and ductwork. I wanted to install AC utilizing the existing system. I consulted with several HVAC contractors and received quotes. Mina was the most knowledgeable of the group of contractors, provided the best suggestions, and also had a very competitive price. During the installation the ductwork turned out to be in poor condition. Mina replaced the ductwork and only charged me the cost of material and not the labor. For anyone who has done contracting this in unheard of. Change orders are often outrageously priced. Mina is an honest man who does good work and cares about satisfaction with the job. If you have the opportunity to use Mina I highly recommend him. The system has been installed and running for 1 month and all continues to work great. Thank you Mina.
