No cool, 8 year old Carrier 2 stage cooling system, Found outdoor unit board didn’t have power due to failed surge protector, surge protector needs to be replaced, quoted and homeowner accepted, replaced surge protector today and tested system functions, system called for cooling 2nd stage and everything came on with normal operations, future repair could be the outdoor board failure due to wear. Left system operational at my departure and cooling at this time, thank you for choosing total air.
