Variations among vendor services

HVAC vendors offer several different levels of service — be sure to consider the following before deciding on one:

  2. How much are you willing to spend?
  3. How much of your system and its parts are you willing to leave to chance?

Always remember to compare and contrast — not all contracts are created equal.
