You’ll want to check for a manufacture date. This is usually located on a label on the surface of your unit.
If your equipment is less than five years old, it may still be warrantied. At the same time, warranty terms and conditions vary by manufacturer and installing company.
At A1 Chesney Service Experts, we can confirm your warranty status with a system inspection. We also provide HVAC service memberships in Calgary for residential heating and AC equipment, regardless of unit age or manufacturer warranty standing.
