A retail floor, office suite, or restaurant dining room cannot stay open long once the cooling stops. F. J. Air Services LLC installs and maintains commercial HVAC equipment for property managers, facilities leads, and business owners in Naples. Our technicians are NATE certified, and the company is a Florida State Certified Contractor.


We cover the full range of equipment found in commercial buildings, from the units on the roof to the controls that tell them when to run.

Equipment We Install and Maintain

Our team handles installation and maintenance for all types of commercial HVAC equipment. The systems we see most often fall into four groups.

  • Rooftop Units

    Packaged rooftop units are commonly used in strip malls, standalone retail stores, and low-rise office buildings. We install and maintain rooftop HVAC units up to 25 tons, helping keep commercial spaces comfortable and systems operating efficiently.

  • Split Systems

    Split systems are a common choice for smaller commercial suites and buildings where HVAC equipment is installed at ground level. We provide professional installation and scheduled maintenance to support reliable performance and long-term system efficiency.

  • Exhaust and Supply Fans

    Kitchens, restrooms, and work areas need air moving in and out. We install and maintain exhaust and supply fans as part of the overall system.

Planned Maintenance for Commercial Buildings

Commercial equipment runs longer hours than residential units and carries heavier loads, especially through a Southwest Florida summer. Scheduled maintenance lets a technician find wear before it becomes a shutdown during business hours. It also keeps energy use in check, which matters on a building with several rooftop units running at once.



If you manage more than one property, we can look at the equipment across your locations and help you plan service around how each building is used.

Replacing Aging Commercial Equipment

At some point, keeping an old rooftop unit or chiller running costs more than it saves. We offer a free estimate on a new system replacement, so you can weigh that decision with real numbers in front of you. The brands we install include Rheem, Lennox, and Trane.


Many of the buildings we work in also run cold storage. If yours has walk-in coolers, ice machines, or display cases, our commercial refrigeration installation and repair covers that equipment, so one contractor can handle both. For residences, see our residential air conditioning services.
