Commercial HVAC in Jacksonville, FL
Repair, Installation & Maintenance Backed by 40+ Years of Northeast Florida Service
David Gray has been serving businesses across Northeast Florida since 1983. We handle commercial HVAC repair, installation, and maintenance alongside plumbing and electrical services, giving you one team to call instead of three. When a system goes down during a workday, you don’t want to coordinate multiple contractors. You want someone who shows up prepared and addresses the issue.
Jacksonville’s heat and humidity place real demand on commercial equipment. Systems run longer here, work harder, and are more likely to break down when maintenance slips. We price every job upfront, explain your options before work begins, and don’t charge extra for evening or weekend calls.

Commercial HVAC Services We Provide
Our technicians diagnose and repair commercial HVAC systems by tracing problems to their source. A patched symptom that returns next month can cost more than addressing the root cause today. Fully stocked trucks let us resolve most issues in a single visit, keeping disruption to your operation to a minimum.
We also handle complete system installation and replacement, including ductless mini-split systems and thermostat upgrades. When a system is aging or no longer performing reliably, we walk you through replacement options sized and selected for your building.
For businesses that want to stay ahead of breakdowns, we offer maintenance plans designed to support long-term system health. Scheduled service helps keep equipment running through peak season and gives you a documented service record, which many manufacturers require to honor warranty coverage.
Why Jacksonville Businesses Work with David Gray
Four decades of service in Northeast Florida have shaped how we work. We show up on time, communicate clearly, and stand behind the job. That approach has earned us BBB accreditation, HomeAdvisor Top Rated and Screened and Approved status, and the 2024 Angi Super Service Award.
The multi-trade model is what sets us apart for commercial clients. Your building doesn’t limit its problems to one system, and we don’t limit our capabilities to one trade. HVAC, plumbing, and commercial electrical work are all handled by the same team. If you call about an HVAC issue and we find an electrical concern in the same visit, we can address both without bringing in a second company.
Not sure whether a repair quote you received is fair? We offer free second opinions on costly repair or replacement decisions. No pressure, just a straightforward assessment so you can move forward with confidence.
Commercial HVAC Maintenance Plans in Jacksonville
Jacksonville’s long cooling seasons push commercial HVAC equipment hard. That sustained workload is exactly why scheduled maintenance matters. A system that goes unserviced can develop small issues that turn into mid-season failures at the worst possible time.
Our maintenance plans are built around helping keep your equipment reliable. During a visit, our technicians inspect electrical connections, clean coils, verify refrigerant levels, and check thermostat and safety control performance. The goal is to catch what’s developing before it becomes a breakdown.
We arrive prepared on every visit, and because we don’t charge extra for evenings or weekends, scheduling works around your business rather than against it. If a technician identifies a deeper issue during the visit, we explain what we found and what it means before any additional work is discussed.
Call (904) 605-8190 to schedule commercial HVAC service, request a second opinion, or ask about a maintenance plan. David Gray serves Jacksonville and the surrounding Northeast Florida area with no extra fees for evenings or weekends.
Common Commercial HVAC System Types
The type of system your building uses affects how it’s maintained, how it fails, and what replacement involves. Here’s a brief overview of the configurations most common in Jacksonville commercial properties.
Rooftop Units
Rooftop units (RTUs) are among the most common choices for commercial buildings. They keep all equipment off the floor, free up interior space, and make maintenance access straightforward. A single RTU can serve a large open area efficiently.
Packaged Units
Packaged units combine heating and cooling components in one cabinet, typically installed on a rooftop or on a pad outside the building. The all-in-one design simplifies service and reduces the number of connection points between components.
