You’ll want to check for a manufacture date. This is usually found on a label on the surface of your equipment.
If your system is newer than five years old, it might still be under warranty. However, warranty terms and conditions vary between manufacturer and installing company.
At Bryant Heating & Cooling Service Experts, we can confirm your warranty standing via a system inspection. We also offer HVAC service memberships in Windsor for residential heating and cooling equipment, regardless of system age or manufacturer warranty standing.
