Brennan Heating, Air Conditioning, & Electric

Brennan Heating, Air Conditioning, & Electric has kept Western Washington homes comfortable since 1987, building a reputation that shows in their near-perfect 4.9-star rating across 46 verified reviews. Based in Lakewood, the company serves homeowners across the Puget Sound region, including Seattle, Bellevue, Kirkland, Renton, Federal Way, Kent, and South Hill. Their team handles heating, cooling, plumbing, electrical, and indoor air quality projects with a commitment to transparent pricing and clean work surfaces. The company maintains an A+ Better Business Bureau rating and has earned 13 Angie's List Super Service Awards, reflecting decades of consistent service to communities throughout Western Washington.

This contractor stands out as an authorized Lennox dealer, offering some of the most efficient residential heating and cooling systems available. Their free energy consultations help homeowners understand how their property consumes energy and identify practical upgrades that lower utility costs. They install heat pumps, tankless water heaters, and advanced air purification systems including Aeroseal duct sealing. Brennan provides flexible financing for approved credit, comprehensive warranties covering both equipment and workmanship, and 24/7 emergency availability with same-day and weekend appointment options. Their commitment to energy efficiency extends to standby and portable generator installations that keep homes powered during outages, a practical consideration for a region that experiences periodic winter storms.

Homeowners consistently praise specific technicians for resolving urgent problems. When Jenn Barnes' furnace failed during a cold snap, the team squeezed her in same-day, worked after normal hours, and ensured she had a heated home before the weekend. Dakota, who appears in multiple reviews, explained generator systems thoroughly during annual servicing and performed HVAC maintenance while keeping customers informed throughout the process. Daniel was dispatched the same day a neighbor recommended Brennan, and he spent extra time troubleshooting a furnace problem that a previous contractor couldn't solve, teaching the homeowner what to observe if the issue recurred. These named interactions illustrate why reviewers repeatedly describe the company as their go-to for future HVAC needs.
