About Brennan Heating & Air Conditioning

AC Services typically cover system inspections, diagnostics, refrigerant and airflow checks, filter and coil maintenance, and repairs for failing compressors, fans, and thermostats. Heating Services address furnace and heat pump tune-ups, ignition and safety checks, and repairs when a system stops producing heat. Each job begins with an assessment so customers understand what is happening inside their equipment before any work is recommended.

Brennan Heating & Air Conditioning serves Seattle and the surrounding area, where mild winters, cool marine air, and older housing stock create their own demands on heating and cooling equipment. Familiarity with local conditions helps technicians anticipate issues common to the region's homes and commercial buildings.

People comparing local HVAC pros should ask about the scope of an estimate, how repairs are documented, and what maintenance options are available. Clear answers to those questions are often a good sign of a dependable contractor.
