Air ducts are not designed to last forever. Like other parts of your HVAC system, after a prolonged period of use, they will eventually begin to wear and tear. Signs of wear and tear in the air duct are similar to the signs of an air duct that needs repairs. When your air duct begins to give you problems, you may be faced with the decision of if to repair the current unit or replace it with a new one. While extensive repairs may help you fix leaks in your air duct, a time will come when replacing the unit will be the more cost-efficient and logical option over repairing it. When that time comes, you will need a professional and reliable HVAC service company to entrust your air duct replacement needs to, Universal HVAC is that company.
