You’ll want to look for a manufacture date. This is typically situated on a label on the surface of your equipment.
If your equipment is under five years old, it could still be protected by a warranty. At the same time, warranty terms and conditions differ manufacturer and installing company.
At Norrell Service Experts, we can confirm your warranty status via a system inspection. We also offer HVAC service memberships in Birmingham for residential heating and AC equipment, regardless of equipment age or manufacturer warranty validity.
