About B&D Heating and Cooling LLC
B&D Heating and Cooling LLC operates as a home heating and cooling contractor serving Columbia, South Carolina, and the broader CSRA region. The business maintains a perfect 5-star rating derived from a single client review, reflecting a commitment to resolving complex HVAC failures that have eluded other service providers in the area.
What distinguishes this contractor is their technical capability with nonstandard equipment. Rather than defaulting to component replacement based on surface-level symptoms, their approach involves systematic troubleshooting using manufacturer diagnostic protocols and accessing specialized knowledge to identify root causes. The review references their ability to locate and install replacements for aging circuit boards that many suppliers no longer carry, alongside handling unconventional repairs such as addressing slow refrigerant leaks with purpose-formulated stop-leak materials designed for HVAC applications.
One Columbia homeowner detailed a two-year frustrating cycle with a prominent regional competitor who repeatedly misdiagnosed an intermittent shutdown issue on a main cooling system, incorrectly replacing a motor at significant cost before the same problem resurfaced the following cooling season. After contacting B&D, a service technician arrived within 24 hours, accurately identified the faulty circuit board using built-in diagnostic codes, sourced a compatible replacement for the decade-old component, and completed installation within approximately two hours while simultaneously addressing a secondary leak contribution that had complicated the initial diagnosis.
What Customers Say
The single client review awards 5 stars, specifically highlighting B&D's ability to diagnose and resolve an intermittent problem that another contractor failed to fix over two-plus cooling seasons. The reviewer emphasizes their technical proficiency in troubleshooting circuit board issues using built-in diagnostic tools and praises their swift response time.
