WARRANTIES ON ALL AC SYSTEMS MUST BE INSTALLED BY A C-20 CERTIFIED CONTRACTOR EXAMPLE: IF A UNIT HAS A 5/15 YEAR WARRANTY WE COVER ALL PARTS–SUCH AS 5 YEARS ON THE COMPLETE UNIT 15 YEARS ON THE COMPRESSOR. NOT LABOR! KNOW WHAT YOU ARE DOING! YOU AS A CONTRACTOR SHOULD TELL US WHAT PART YOU NEED On failure normally only one part goes bad, not two. Make sure you are positive of the one part that is wrong with the unit! WE ARE WHOLESALE DISTRIBUTORS, NOT A HOME DEPOT
