What to do now

Get a replacement quote now, before a breakdown in the hottest or coldest week forces a rushed choice.
A common rule of thumb: if the repair cost times the age in years is over 5,000, replacing usually makes more sense.
Ask about rebates. Many utilities and states pay toward a high-efficiency replacement.
Some home insurers and home buyers’ inspectors ask the age of the HVAC system. Florida 4-point inspections record it.
Most HVAC parts warranties run 5 to 10 years and require registration within 60 to 90 days of install. Check with the installer.

Where the serial is on a Goodman

On a furnace or air handler, remove the front door: the rating plate is on the inside wall of the cabinet. On an outdoor unit, look on the side of the cabinet near the electrical panel.

Turn off the furnace switch before removing the front door. The outdoor unit’s plate is usually on the side panel near the electrical connections, sometimes on the back.
