Heat Flow Mechanical LLC

Heat Flow Mechanical LLC operates as a licensed HVAC contractor serving the Seattle metro area, including Kenmore and surrounding King County neighborhoods. With a 4.9-star rating accumulated across 10 customer reviews, the company has built a reputation for precise installations backed by technical documentation. Luke, the lead technician, pulls original building blueprints when sizing replacement furnaces and cooling systems, ensuring new equipment matches the heating and cooling loads calculated for homes built decades ago.

This contractor differentiates through brand partnerships with American Standard for furnaces and air conditioners, and Navien for tankless water heater systems. The Navien tankless installations represent a specialized niche requiring gas line expertise and permits, areas where Heat Flow Mechanical handles the entire process from inspection to final connection. Customers consistently note the willingness to work within budget constraints while delivering quality equipment installations.

Reviewers describe specific scenarios that illustrate the company's approach. Scott Myers credited Luke with using 20-year-old blueprints to properly size equipment for his home, resulting in efficient heating and cooling. David Dye compared multiple bids before selecting Heat Flow Mechanical, praising the team's willingness to install quality products on a budget. Kevin Donahue needed a gas line extension for his kitchen and fireplace, and the crew returned the same day to rework a stove connection without delay.
