Power And Flow Contracting operates from Baltimore, Maryland, holding an active contractor license and maintaining a perfect 5.0-star average across 71 verified client reviews. Founded to serve both residential homeowners and light commercial property owners, the company fields a single primary technician named Harvey alongside support staff, enabling direct communication from first call through final inspection. The crew covers projects throughout Baltimore city proper, Anne Arundel County, and the neighboring community of Dundalk, responding to service calls in homes, townhouses, and small commercial spaces. Estimates are provided on-site during the initial visit, with all pricing confirmed before work begins.
This contractor handles three distinct trade disciplines under one roof: HVAC repair and maintenance, plumbing, and electrical work. Rather than subdividing into separate service lines on their intake calls, the team books each trade through a single phone line at (443) 938-4164. All project visits include a written scope and cost summary, giving property owners a clear record of agreed work before any disassembly begins. No brand partnerships or equipment rebates appeared in available records, and the company does not currently maintain a public website where material specifications or manufacturer certifications would be posted.
Reviewers repeatedly name technician Harvey when describing their experiences, with multiple customers noting same-day arrival after an emergency call. One homeowner called for furnace diagnostic work during a heating season issue, describing Harvey as efficient and knowledgeable about system controls. Another customer engaged Harvey for electrical conduit routing to a backyard shed, with the technician explaining each wiring step and adjusting pricing to fit a constrained budget. A third reviewer reports ongoing work spanning more than five years, mentioning consistent same-day availability and upfront cost disclosure before each project starts. Carmen noted referral-based discovery, suggesting word-of-mouth drives a portion of their Baltimore client base.
