You’ll want to look for a manufacture date. This is usually situated on a label on the exterior of your equipment.
If your system is newer than five years old, it could still be warrantied. However, warranty terms and conditions differ manufacturer and installing company.
At McElroy Service Experts, we can verify your warranty standing through a system inspection. We also provide HVAC service memberships in Grand Island for residential heating and AC systems, regardless of system age or manufacturer warranty status.
