If your equipment is under five years old, it might still be warrantied. Having said that, warranty terms and conditions vary between manufacturer and installing company.
At Service Experts Heating & Air Conditioning, we can confirm your warranty status through a system inspection in West Palm Beach for residential heating and cooling equipment, regardless of system age or manufacturer warranty standing.
