Professional HVAC Services

Professional HVAC Services at Sun State HVAC

AC Repair, Heating, Air Balance, Refrigeration and HVAC Repair, is all we do at Sun State HVAC and we are experts at it. 

It’s not easy to find truly great AC Repair Technicians and those who do exist require and deserve a decent income.  Because of this many of the formerly advertised AC Repair companies have suddenly become plumbing specialists! They now even advertise “Plumbing and Air Conditioning instead of the other way around, making Plumbing their primary source of business!  A wise man might say, let auto mechanics be auto mechanics; doctors be doctors; plumbers be plumbers, and HVAC technicians be HVAC technicians!


Obviously, both HVAC technicians and plumbers provide important services but they do so from completely  different mental views.  

For instance, a highly qualified AC technician will not provide standard plumbing tasks e.g. snaking drains, running cameras through sewer lines, digging trenches cutting through concrete to repair or replace broken sewer or other drain or supply pipe systems.  They will also not replace old corroded attic galvanized water supply lines.  This is not because he or she cannot or does not know how to do it but because this type of work is mentally not what normally intrigues a student who wishes to be a highly  trained HVAC technician in the first place.  Technicians of this type are intrigued by electromechanical and enthalpy more in line with physics than the physical. 


With Sun State HVAC you never have to worry that something might be missed.
