A single review from the Burlington Historical Society documents a challenging customer experience involving two failed air conditioning units at the history museum. The reviewer states PremiStar repaired one unit while describing the second as requiring minor repairs, yet the unit subsequently failed due to an undetected freon leak. The customer reported difficulty contacting the company, an absence of itemized invoicing, and quoted pricing that exceeded two competing bids without detailed equipment specifications. This review represents the entirety of publicly available customer feedback for this contractor.
