About Heat N.W. LLC
Heat N.W. LLC operates as a licensed HVAC contractor serving Portland, Oregon and surrounding communities with installations and repairs. Based on available customer feedback indicating comprehensive service across heating and cooling systems, the company handles residential heat pump work, system replacements, and diagnostic repairs. With all 28 verified reviews yielding perfect 5-star ratings, the business has established a track record of resolving challenging equipment issues that other contractors decline to address.
What distinguishes Heat N.W. LLC is the technical depth behind each service call. Customer reviews reference an engineering-minded approach combined with practical troubleshooting skill, enabling resolution of complex problems involving refrigerant leaks, aging heat pump units, and multi-system interactions. The company appears to prioritize correct installation practices on the first attempt, with at least one customer noting an inspector subsequently requested Heat N.W. to install their own system.
Mark emerges across multiple customer accounts as the primary technician delivering these results. One homeowner recounted how other companies refused to examine their heat pump, insisting on a replacement, while Mark identified a freon leak within seconds and restored better-than-new performance. Another described a 14-year-old Rheem heat pump that Mark diagnosed and repaired in a single visit, including preventive modifications. A third reviewer credited Mark with discovering and correcting multiple underlying issues beyond the stated complaint, ensuring the entire system operated at peak efficiency.
