If your system is under five years old, it may still be protected by a warranty. However, warranty terms and conditions vary between manufacturer and installing company.
At Service Experts Heating & Air Conditioning, we can confirm your warranty standing through a system inspection. We also provide HVAC service memberships in Canada for residential heating and air conditioning equipment, regardless of system age or manufacturer warranty status.
