You’ll want to look for a manufacture date. This is typically situated on a label on the exterior of your system.
If your system 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 Stark Services, we can verify your warranty status through a system inspection. We also provide HVAC service memberships in Haltom City for residential heating and cooling systems, regardless of system age or manufacturer warranty standing.
