You’ll want to find a manufacture date. This is frequently found on a label on the exterior of your equipment.
If your system is less than five years old, it could still be warrantied. Having said that, warranty terms and conditions vary between manufacturer and installing company.
At D.A. Bennett Service Experts, we can verify your warranty status via a system inspection. We also offer HVAC service memberships in Albany for residential heating and air conditioning equipment, regardless of equipment age or manufacturer warranty standing.
