You’ll want to look for the date it was made. This is frequently found on a label on the exterior of your equipment.
If your equipment is less than five years old, it could still be under warranty. Having said that, warranty terms and conditions vary by 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.
