Deem LLC

Based in Lakeland, Florida, Deem LLC operates as a commercial and industrial construction contractor serving the greater Polk County area and multiple states across the Southeast. With a 4.0-star rating from 11 customer reviews, the company provides integrated mechanical and construction services to retail, commercial, institutional, and industrial facilities. The company maintains a 24/7 emergency service line alongside a dedicated in-house team capable of handling new construction projects and existing-system retrofits alike.

What distinguishes Deem LLC from general contractors is its breadth of in-house trades under one roof. The company self-performs HVAC installation and service, electrical and data work, plumbing, refrigeration, industrial piping, and building automation without relying on subcontractors. A notable specialty includes industrial ammonia refrigeration systems, a niche requiring specialized certification that most residential contractors cannot offer. Additionally, Deem publishes an active community outreach program and partnerships with organizations including Victory Unlimited and Victory Surfaces, signaling deep roots in the regions it serves.

The most enthusiastic reviews single out Deem's refrigeration capabilities, with James Carlton declaring it the best refrigeration company in Florida and Jesus Morales adding a confirming endorsement. Both reviews are brief but specific, reflecting direct experience with the company's refrigeration design, installation, and service work. Critical feedback from Matt Augusta and Vikki Hart points to driver behavior rather than service quality, with concerns about speeding and unsafe lane changes on public roads.
