HVAC Services Tigard OR | Call NorthWest Engineering Service

We often find that uneven heating in local homes stems from airflow imbalances or ductwork issues. Our Testing, Adjusting, and Balancing (TAB) service specifically measures and corrects airflow to each room, ensuring your HVAC system distributes conditioned air evenly. We can also assess your home's building envelope for leaks that cause temperature variations. This systematic, engineering-led approach resolves the root cause, not just the symptom, for lasting comfort.

Our installation process is thorough and engineered for long-term performance. We start with a detailed assessment of your home's layout and needs, followed by proper system sizing and selection to avoid inefficiency. Our employee-owned team handles the installation with precision, followed by commissioning—a rigorous testing process to verify the system operates at its designed specifications for efficiency, airflow, and safety. We ensure your new system is optimized from day one.

We service both. For existing homes in Tigard, we specialize in retro-commissioning. This is a detailed investigation of your current HVAC system to identify inefficiencies, poor performance, or comfort issues. We then make precise repairs or adjustments to restore optimal operation, improve indoor air quality, and reduce energy waste. It's a cost-effective way to upgrade your home's performance without a full replacement.
