You’ll want to find a manufacture date. This is usually found on a label on the outside of your system.
If your equipment is less than five years old, it may still be under warranty. However, warranty terms and conditions vary by manufacturer and installing company.
At Chief/Bauer Service Experts, we can verify your warranty standing with a system inspection. We also offer HVAC service memberships in Champaign for residential heating and AC systems, regardless of equipment age or manufacturer warranty validity.
