When should I replace my heating, cooling and ventilation system?
You should start thinking about replacement when your HVAC equipment is 15 years or older. On average, non-maintenanced equipment will last anywhere from 10-15 years. Maintenanced equipment will live about 15-20+ years. Keep in mind you can make a system last as long as you want if you keep repairing and replacing broken parts. Eventually you will have to when it makes more sense to replace rather than repair it.
