Columbia Heating & AIr Conditioning

Columbia Heating & Air Conditioning is a local HVAC contractor serving the Seattle metropolitan area from an Eastside base, holding a 5-star rating across 11 reviews. Mark, the lead technician, handles residential repair and maintenance work, taking on both urgent calls and planned service visits. Customers praise his ability to diagnose problems other companies missed, and his habit of arriving with parts already in hand so jobs finish in a single trip. The review record shows no complaints about pricing, no mentions of upselling unnecessary equipment, and repeated references to fair cost. That track record makes this contractor a reliable choice for homeowners who need an honest assessment of their furnace or AC.

What sets Columbia Heating & Air Conditioning apart is the direct, no-nonsense approach Mark brings to every job. He asks detailed questions before agreeing to a visit, so customers know he believes he can solve the problem before he commits. Once on-site, he works efficiently, typically finishing repairs within hours rather than days. Several reviewers noted he also shared maintenance tips and efficiency advice without being asked, suggesting he treats service as more than just a transaction.

Tom Bergman describes calling Columbia after another company charged him 200 dollars twice and then suggested a 10,000-dollar replacement. Mark spent 30 minutes identifying a faulty contactor, had the part available, and had Bergman's system running again before lunch. Mary Giuntini booked a same-day appointment and watched Mark diagnose both her AC unit and her thermostat in a single visit, finishing everything in a few hours. Bonnie Beckley needed multiple heater repairs, and Mark located the necessary parts and completed the work in two hours at what she called a very reasonable cost. Across every review, the technician named is Mark, and the consistent theme is accurate diagnosis and efficient repair.
