You’ll want to look for a production date. This is typically found on a label on the surface of your equipment.
If your equipment is newer than five years old, it may still be warrantied. Having said that, warranty terms and conditions vary by manufacturer and installing company.
At Service Experts Heating & Air Conditioning, we can confirm your warranty state with a system inspection in Edmonton for residential heating and air conditioning equipment, regardless of unit age or manufacturer warranty standing.
