    Hector Martinez- Managing Partner
    Hello I am Hector Martinez, I am the managing partner for Martinez A/c & Htg, Inc.; it seems that I have been in the business all my life and being groomed for this by my father Adan and mother Lupe who started this business back in 1976. The Lord has blessed me with a wonderful partner, Christina, to share in the joys of life and help in the hard times of this life, I have two wonderful children, Desiree & Devina who have made me a proud grandfather and one niece, Ruby, who I raised.

    While learning this trade, I joined the Army Reserves in 1986 and for the next 21 years my duties were to be an Operating room technician (1986-2001) and later a Career counselor (2001-07) from a Private to SFC. During that time, I served in Desert Shield/Desert Storm and numerous other training events. Currently I am a member of VFW Post 6119. I feel my experiences in the Army has helped me to deal with running a business when its easy and when its hectic and all along balancing family life. As a former GW city councilman (1991-92) and later the Planning and Zoning Committee (2008-16), also the Live Oak County Economic Development Council (1992-93) and several other volunteer organizations throughout my life, I have found that some of my best experiences have been when I have helped people succeed. That is what I want for my employees and customers.
