You’ll want to look for the date it was made. This is frequently found on a label on the surface of your equipment.
If your equipment is less than five years old, it might still be under warranty. However, warranty terms and conditions differ manufacturer and installing company.
At Finch Air Conditioning & Heating, we can check your warranty status via a system inspection. We also offer HVAC service memberships in La Porte for residential heating and air conditioning equipment, regardless of system age or manufacturer warranty status.
