The Comfort Zone Heating and Cooling apologizes for any dissatisfaction Dorothy Bolton may have towards our company. Comfort Zone entered into a contract with Dorothy Bolton November 30, 2007 to include the following. [Gas connection in attic from basement, flu pipe from unit through roof, Refrigeration line connect, evacuation leak test, A coil mounted to unit, filter rack and filter, condensate drain, humidifier including water supply, control wiring, all grills, supply and return connection to unit, and start up] Our warranty states [All materials and labor are guaranteed for 1 year against defects or poor workmanship and shall receive free repair during normal working hours for that period.] Our company DOES believe that the compressor is defected, and would be covered under the manufactures warranty. However OUR company DID NOT provide Dorothy Bolton with the equipment. Making it impossible for us to be able to recover warranty coverage for equipment we did not provide. Our advice to Dorothy is to find her previous contractor that delivered and installed her units and acquire the paperwork the unit was purchased with.
