Repair or Replace? Making the Right Call for Your Heating System

Facing a malfunctioning heating system can leave Merrimack homeowners wondering whether it's best to repair or replace it. Consider the following factors to make an informed decision:


  • If your heating system is relatively new and the issue is minor, repairing is often the cost-effective choice.
  • Regular maintenance and occasional repairs can extend the life of your system, postponing the need for a replacement.


  • If your heating system is over 15 years old and experiencing frequent breakdowns, a replacement may be more economical in the long run.
  • Older systems tend to be less energy-efficient, leading to higher utility bills. Upgrading to a newer model can result in substantial savings.
  • If the cost of repairs exceeds the value of your heating system, investing in a new one makes better financial sense.

At A. Fagundes Plumbing & Heating, we provide honest assessments to help you determine the best course of action for your Merrimack home's heating system.
