About Mark Hurm & Co., LLC
Mark Hurm & Co., LLC has served the Gainesville area as a licensed HVAC contractor for multiple decades, building a reputation through consistent service and community trust. The company holds 557 client reviews with an exceptional 4.9-star average rating, reflecting a long track record of successful installations and repairs. Operating around the clock every day of the week, their team responds to emergency calls throughout Alachua County and surrounding municipalities. This full-service contractor handles both residential and light commercial projects, from routine maintenance to complete system replacements.
As a Lennox authorized dealer, Mark Hurm & Co., LLC leverages factory training and direct access to equipment warranties that independent shops cannot match. Their expertise extends to integrating advanced HEPA filtration systems with existing HVAC infrastructure, a specialty that requires understanding airflow dynamics and system compatibility. The company offers annual maintenance programs that keep systems running efficiently year-round, particularly important in Florida's demanding climate where AC units operate under heavy loads.
Customer reviews highlight specific team members who deliver exceptional service. RJ, the Design Manager, earned praise for designing a custom HEPA filtration integration with a Lennox system, identifying layout inefficiencies and having his team reconfigure ductwork for optimal performance. Ken, a maintenance technician, has built trust with long-term customers through the annual service program, providing fair pricing and clear communication. For one homeowner facing a three-day attic duct replacement during summer heat, the crew navigated extremely tight crawl spaces to install new trunk lines and vents, demonstrating the hands-on dedication that generates five-star reviews.

No negative feedback appears in the available reviews, with customers praising communication, pricing transparency, and attention to detail.
