You’ll want to check for a production date. This is typically found on a label on the exterior of your equipment.
If your equipment is under five years old, it might still be warrantied. Having said that, warranty terms and conditions vary between manufacturer and installing company.
At Service Experts Heating & Air Conditioning, we can verify your warranty status through a system inspection. We also have HVAC service memberships in Orlando for residential heating and AC units, regardless of system age or manufacturer warranty standing.
