If you spot these signs, schedule a ductwork inspection before small issues become bigger problems:

• Inconsistent temperatures across rooms
• Weak airflow coming from the vents
• Unexplained energy bill increases
• Dust around vents, even with repeated cleaning
• Loose, cracked, or disconnected ducts

After assessing your ducts, we explain your options and provide up-front pricing before work begins.

Certified, licensed, and insured HVAC technicians follow these five proven steps to seal your ducts:

1. System shut-off: Before starting work, we turn your HVAC system off. This step helps us inspect the duct without moisture affecting the work area.
2. Inspection: We unfasten the insulation to assess the duct and check for signs of rust.
3. Sealing: If the duct is in good condition, we reposition and secure the existing insulation. Our technicians apply mastic to seal leaks and strengthen the connection.
4. Documentation: We take pictures of the completed work so you can see what we fixed.
5. Testing: Your technician turns the system back on and checks the Delta-T. This measurement shows the temperature difference between the air entering and leaving the system’s indoor coil. High Delta-T signals poor airflow, and a low number suggests poor capacity or inefficiency. We verify that air moves through your system as expected for reliable performance.
