Duct Sealing in Phoenix & the Phoenix Metro Area
Leaky ducts in a Phoenix attic dump cooled air into a space that hits 130°F in summer, which means the system works overtime to condition rooms it never reaches. George Brazil provides professional duct sealing that closes those leaks and puts the air back where you paid to send it.

Duct Sealing Tips & FAQs
How much does duct sealing cost?
Duct sealing costs vary depending on the size of your home’s ductwork, the number of leaks, and system accessibility. We’ll perform a duct leakage test and give you an upfront quote with no hidden fees.
What are the benefits of duct sealing?
Professional duct sealing can:
- Improve the efficiency of your home’s heating, ventilation, and air conditioning system
- Lower your utility bills
- Prevent energy waste caused by leaky ductwork
- Reduce indoor allergens and dust
- Enhance indoor air quality and comfort
- Extend the life of your HVAC system
How do I know if my ductwork is leaking?
Leaky ducts often go unnoticed until they impact comfort or energy bills. Common signs include uneven heating or cooling across different rooms, excessive dust buildup, whistling or rattling noises from vents, and higher-than-normal utility costs. You might also notice weak airflow or rooms that are hard to heat or cool. In some cases, visible damage or disconnected sections in exposed ductwork (like in basements or attics) may be obvious.
If you’re experiencing any of these scenarios, schedule a professional air duct inspection and duct pressure test. Our team uses specialized tools to pinpoint exactly where your ductwork is leaking and recommend targeted repairs or sealing solutions.
Do you offer commercial air duct sealing?
Yes, our HVAC specialists also provide commercial duct sealing services for offices, retail spaces, and industrial buildings.
