    AC Repair

    It is a well known fact that summer temperatures in our ‘Valley of the Sun’ often soar above 115 deg F and often cross above the 120 deg F area!   This kind of heat can feel devastating to those who have never experienced it before and many valley residents even experience forms of anxiety as a result. Winters in the area are for the most part quite mild. Because of this newcomers to the Phoenix area valley often don’t realize how important it is to have a properly maintained well operating air conditioning system until the summer hits and we get the seasons first really hot weekend.   Read More…

    Heating Repair

    In fact normal winter temperatures rarely fall below the low 30’s, and sometimes into the high teens but even so, because of the area’s low humidity, 30 degrees can actually feel much, much colder and again when it is really dry you can feel bone-shivering chills even at temperatures up into the 40’s and above!  Read More…

    Restaurant HVAC

    The reason is because Sun State HVAC restaurant service was literally born as a direct result of the founders 25 years of restaurant operations background by way of being born to parents who owned and operated a Phoenix AZ family delicatessen, restaurant and fresh meat business for 52 years.  Mark Gresin says –  Read More…
