You’ll want to find a manufacture date. This is typically found on a label on the surface of your system.
If your system is newer than five years old, it might still be warrantied. However, warranty terms and conditions vary by manufacturer and installing company.
At Coastal Service Experts, we can verify your warranty standing with a system inspection. We also have HVAC service memberships in Savannah for residential heating and AC systems, regardless of unit age or manufacturer warranty status.
