HVAC duct cleaning and repair by AttiCal licensed technicians in San Jose, CA.

Professional HVAC Cleaning and Repair You Can Trust

A dirty or failing HVAC system works harder for less result. Restricted airflow from clogged coils, dirty blowers and contaminated ducts forces the equipment to run longer, drives up your bill and shortens equipment life — often years before it should have failed.

AttiCal cleans and repairs residential HVAC systems across the Bay Area. We clean ducts and registers, service coils and blowers, correct airflow problems and diagnose the electrical and mechanical faults behind the symptoms you are actually noticing.

If your ducts run through an attic that has had rodents, cleaning the ducts without addressing the attic just recontaminates them. Because we handle both, you get the real fix. Licensed contractor since 2011, Attical Inc. # 1126472.

  • Dust blowing from registers, or visible debris in the ducts
  • Musty or burning smells when the system starts
  • Rooms that never reach the thermostat setting
