Blower Door Testing

Don't settle for guesswork when it comes to your home's comfort and efficiency. A blower door test is a comprehensive diagnostic check that precisely measures the amount of air escaping from your entire home structure.


Think of it as a health check for your home's envelope. By identifying exact leakage points—from loose connections deep within the building structure to unsealed entry points—we can pinpoint the areas that are costing you money and comfort.

Duct Blast Testing

Duct blast testing is a critical step in ensuring your HVAC system is operating at peak efficiency. This process measures how much air is leaking from your ductwork—helping identify hidden energy loss, comfort issues, and code compliance concerns.


At Cochran Complete Services, we use specialized equipment to accurately test and evaluate your duct system. Whether you're building a new home, completing renovations, or need to meet local energy code requirements, our testing provides clear, reliable results.



By identifying and addressing duct leakage, we help improve airflow, increase system efficiency, and reduce energy costs—so your home stays comfortable year-round.
