About ZV HVAC, LLC
Baltimore-based ZV HVAC LLC has earned a perfect 5.0-star average across 121 customer reviews, establishing a track record that speaks clearly on its own. Technicians carry Maryland Journeyman licenses, and the crew has handled projects for homeowners across Baltimore and Anne Arundel County. The company installs complete heating and cooling systems and responds when an existing unit fails unexpectedly mid-event.
Reviewers repeatedly highlight how the crew explains what needs fixing and why, without pressuring homeowners into extra repairs. Jake Bell describes receiving an on-the-spot diagnosis and a clear quote during a child's birthday gathering, while Megan Miller notes that pricing was honest and the work left no trace behind. This straight-talk approach appears across every review in the portfolio, reinforcing that the company has a repeatable process rather than an improvised one.
Kiersten Durst specifically contrasts the crew with competitors who submitted inflated estimates, a detail that recurs across multiple reviewers. Jake Bell credits Zach for identifying a visible problem quickly and returning the next day to complete the repair before a minor issue became a major expense. Kevin Cook describes the crew as professional and knowledgeable from the first call through final sign-off, with clean workmanship and no upsells at any stage.
