A home warranty policy can provide extra protection for heating and cooling systems and often includes coverage for repair costs. Of course that coverage comes at a cost. Whether your home warranty plan covers your current HVAC system depends on the plan you have. Be sure to research and compare plans carefully. Consider your level of DIY skills and decide if you’d feel better if your HVAC system had additional coverage.


  • Peace of mind if purchasing an older home with an older system.
  • Fixed repair costs per visit.


  • Dollar limit cap per repair or per year.
  • Repair or replace decision not yours to make. If replaced, you may not get to choose the new model.


In addition to being necessary to register for a Trane warranty, your serial number includes some vital information about your unit - if you can decipher the confusing serial number nomenclature. A Trane serial number includes:

  • Manufacturing date (year, month, week, day).
  • Manufacturing plant location.
  • Sequential number.


The model number of your new air conditioner or furnace actually tells you a lot about the features of your new system. Here’s what all the numbers and letters of your Trane model number mean:

  • Type of hvac unit.
  • Refrigerant types.
  • Seer rating.
  • Heating input.
  • Heating stages.
  • Furnace configuration.
  • Hvac ton.
  • Voltage.
  • Compressor series.
