You’ll want to find a manufacture date. This is usually located on a label on the outside of your equipment.
If your equipment is newer than five years old, it could still be warrantied. Having said that, warranty terms and conditions differ manufacturer and installing company.
At Service Experts Heating & Air Conditioning, we can confirm your warranty state through a system inspection in Roanoke for residential heating and cooling systems, regardless of equipment age or manufacturer warranty status.
