    • Using the first, second, third and fourth digits of the Goodman furnace serial number 9709xxx you will find the year and month of manufacture. The first and second digits are the year and the fourth and fifth digits are the month of manufacture. Your Goodman furnace was manufactured in September, 1997.

    • Signs that your Goodman furnace may be nearing the end of its lifespan include increasing energy bills, frequent breakdowns, uneven heating, noisy operation, a yellow or flickering pilot light, rust or corrosion, reduced heating capacity, high carbon monoxide levels, and visible cracks or damage. If you observe these signs, it’s important to have your furnace inspected by a professional HVAC technician to determine whether it should be repaired or replaced. Regular maintenance can help prolong the lifespan of your furnace and reduce the major issues.

  1. My HVAC technician recently told me that the compressor and coils in my Goodman unit are from 1990, even though the furnace itself is a 2004 model. Is this possible, and if so, what could explain the age difference?

    • there are a few possibilities:

      1. Replacement parts: It’s not uncommon for individual components of furnace to be replaced over time, especially if they fail or become outdated. So, it’s entirely possible that the original 2004 Goodman unit had its compressor and coils replaced with older parts at some point.

      2. Misidentification: There’s a chance that either the inspector or the technician might have misidentified the age of the components. It’s always a good idea to double-check the serial numbers or model numbers on the equipment itself against manufacturer records.

      Some technicians might have a more direct communication style, focusing on potential problems without sugarcoating their findings. This can come across as alarmist, especially to laypeople unfamiliar with HVAC systems.

      Without further information, it’s difficult to say for sure what’s going on. However, by rephrasing your question and considering the possibilities I mentioned, you can get a better understanding of the situation and figure out the true age of your Goodman furnace.
