New Commercial Installation
System design and commercial HVAC installation for offices, retail spaces, restaurants, medical facilities, multi-tenant properties, and light-industrial buildings. Discuss your project.
Preventive Maintenance Agreements
Scheduled inspections, service documentation, and commercial HVAC system maintenance built around your facility, equipment, and operating demands. Request a maintenance proposal.

Fast Commercial HVAC Repair With Minimal Business Disruption
Downtime disrupts your business, so our technicians arrive prepared to diagnose the issue, isolate affected areas when possible, and work to restore operation with as little interruption as we can. When your system is down we prioritize emergency same-day service and repairs. Same-day appointments are available during business hours when the schedule allows; requests received when we are closed are handled first thing the next business day.
Cooling and comfort

- Uneven temperatures between zones
- High indoor humidity

What to Expect From Your Commercial HVAC Project

We evaluate the required capacity and the right equipment configuration rather than selecting equipment based only on the existing unit's nameplate.
Written Scope and Options
You receive recommended equipment or service options, project scope, pricing, warranty details, and expected scheduling.
Project Coordination
AmeriTech works with you on equipment delivery, installation access, electrical requirements, and duct or curb work. The details for your building are spelled out in the written proposal.

The system is installed, tested, configured, and reviewed for proper operation.
Ongoing Support
Maintenance and service options are presented to help protect the new equipment and document its condition over time.
Commercial Preventive Maintenance Built Around Your Facility
Consistent commercial HVAC system maintenance can help identify developing problems, reduce avoidable breakdown risk, and support more predictable equipment planning. Every agreement is scoped around your facility rather than a one-size-fits-all visit.

Commercial HVAC Across Greater Orlando
Our service fleet is dispatched from our Orlando office to commercial properties in Orange, Seminole, eastern Lake, West Volusia, and northern Osceola counties. Whether you need a commercial HVAC company for a single retail location or a portfolio of properties across several counties, we are equipped to respond.
Rooftop Package Units in Detail
Rooftop package units are common across Central Florida commercial buildings. A packaged unit puts the compressor, condenser, and air handler in a single cabinet on the roof, which can reduce the need for interior mechanical space and keeps service access in one place. That helps keep maintenance quick and limits disruption to the business below.
Whether you run a small retail suite, a medical office, a restaurant, or a multi-tenant strip center, we size the unit for your actual load, accounting for occupancy, equipment heat load, building envelope, and the way Florida's high ambient temperatures affect cooling capacity at real operating conditions.
Rooftop units suit the flat-roof construction found across Orange, Seminole, and Osceola counties. Our scope covers curb work, duct connections, electrical coordination, and commissioning, not just equipment delivery. We service Daikin, Rheem, American Standard, Carrier, Trane, Lennox, and Bryant rooftop equipment, so we can maintain what is on your roof today and help you choose the right replacement when the time comes.
With systems available up to 25 tons, we handle everything from single-zone light commercial applications to larger multi-zone configurations serving retail, office, and light-industrial facilities.
Large-Scale Split Systems and VRF in Detail
Split systems, with separate indoor air handlers and outdoor condensing units connected by refrigerant lines, can offer design flexibility that packaged rooftop units may not. They can be the more practical choice when interior mechanical space is available, when the building does not support rooftop equipment, or when a multi-zone approach needs independent air handlers in different areas.
We design and install large-scale split systems up to 25 tons. Applications range from server rooms and data closets that need tight temperature and humidity control, to multi-room office suites with independent zone control, to restaurant dining rooms and kitchens with very different thermal loads running at the same time.
Variable refrigerant flow (VRF) is the commercial evolution of ductless mini-split technology. A single outdoor unit serves multiple independently controlled indoor units, and some configurations can heat and cool different zones at the same time. Where occupancy varies significantly by zone through the day, VRF can offer energy-saving potential, though results depend on system design, controls, building use, and operating patterns.
Proper refrigerant line sizing, careful commissioning, and an accurate charge are what separate a system that performs as designed from one that struggles on the first hot Florida afternoon. Our commercial technicians bring the same installation discipline to large systems that we apply to residential work.
Commercial Service and Maintenance in Detail
A failed HVAC system in a restaurant, retail store, medical office, or warehouse is a business operations problem, not just an equipment problem. It affects staff, customers, and in some cases code compliance. Our service fleet is dispatched from our Orlando office, and we service major commercial brands whether or not we installed the equipment.
A preventive maintenance visit on a rooftop unit can catch dirty coils, worn belts, low refrigerant charge, and failing capacitors before they turn into larger repairs. Documenting equipment condition at each visit and tracking it over time can also give you advance notice of components approaching the end of their service life, so capital decisions can be planned on your schedule rather than the equipment's.
