Commercial HVAC That Keeps Your Doors Open.

Rooftop Units · Crane Changeouts · Service Contracts · Emergency Repair

When it goes down, you are losing money. A restaurant that cannot seat, a plaza with angry tenants, an office at 84°F by 11am. We are a Florida certified contractor working Central Florida rooftops since 2006 — from one bad capacitor to a full crane changeout scheduled around your business hours.

One licensed contractor for the whole building.

Commercial equipment fails differently than a house does — and it fails in front of your customers. We cover the rooftop, the ductwork and the controls, and we put the scope and the price in writing before anything gets touched.

Also on the truck: commercial duct cleaning, ductwork repair and fabrication, thermostat and controls, new construction and tenant build-outs from rough-in to final commissioning, and honest guidance on the R-410A phase-out before you spend money on an old unit.

Rooftop Units

RTU repair & replacement

Package units on flat roofs — diagnostics, compressors, boards, economizers, and full changeouts including curb adapters, duct transitions, rigging and crane coordination.

Split & Ductless

Suites, offices & server rooms

Split systems and mini-split zones for tenant suites, back offices, IT closets and anywhere one thermostat for the whole floor was never going to work.

Maintenance

Scheduled service agreements

Planned visits on your calendar, not ours — coil cleaning, filters, electrical, drains, refrigerant checks, and a written report with photos after every single visit.

Emergency

System down, business affected

Priority response for contract sites and same-day effort for everyone else. Tell the office it is a commercial system down and it moves up the board.

Property managers, owners, and the people who open at 7am.

Different buildings break in different ways. These are the ones we are on every week across Orlando, Kissimmee and the 192 corridor.

Restaurants & BarsKitchen heat load, make-up air, and a dining room that cannot be 80°F at dinner service.
Retail & Strip PlazasMultiple tenants, multiple units, one roof — and one contractor who knows which unit feeds which suite.
Offices & MedicalSuites, waiting rooms and equipment rooms where humidity and air quality actually matter.
Warehouses & Light IndustrialBig volumes, high ceilings, and offices bolted onto a space that was never designed to be cooled.
Condo, HOA & Multi-FamilyCommon areas, corridors and unit-level systems, with documentation a board can actually read.
Vacation Rental PortfoliosHigh-turnover homes near the 192 and Champions Gate, with remote owners and tight cleaning windows.
Churches, Schools & NonprofitsBuildings that are empty all week and full on one day — scheduling and staging matter as much as the equipment.
Salons, Gyms & StudiosHeavy occupancy in a small footprint, where airflow problems show up as complaints before they show up as breakdowns.

Crane day starts long before the crane does.

14 seconds from the roof · no edit

That is one of our techs on a Central Florida roof, watching the boom the whole lift. Nothing about that morning was improvised — by the time a crane is on site, the measurements, the curb, the rigging and the shutdown window are already settled. Here is what a rooftop changeout actually looks like from your side of it.

1
We get on the roof firstModel, tonnage, curb dimensions, duct transitions, electrical and access. No quote gets written from the parking lot.
2
The lift gets planned around youCrane placement, roof and street access, and a shutdown window picked to hit your quietest hours — early morning, after close, or a weekend.
3
Old unit off, curb preppedThe failed unit comes down, the curb is cleaned up and adapted if the new footprint differs, and the duct connections get sorted properly instead of shimmed.
4
New unit set and sealedRigged, landed, anchored, flashed and sealed. The part in the clip — the part that takes minutes because the hours before it were done right.
5
Startup, charge, commissioningRefrigerant charge verified, controls tied in, temperature split checked under load — then photos and the written report go to you, not just the invoice.

The part that has nothing to do with refrigerant.

Most commercial customers do not leave a contractor over technical skill. They leave because nobody called them back, the invoice did not match the quote, or they could not explain the charge to an owner.

One contact for the whole portfolioSame company, same people, same history on every building you manage — no re-explaining the site to a new vendor.
Written scope before the workYou approve a price, not a surprise. If we find something else once the panel is open, you hear about it before it becomes a line item.
Photos you can forwardOwner-ready documentation on every visit, so you can justify the spend without being the one on the roof.
Certificate of insuranceFlorida certified contractor, license #CAC1818913, licensed and insured. Send your requirements and we handle it.
Scheduled around your hoursEarly mornings, after close, weekends — whatever keeps your floor open and your tenants quiet.
Straight talk on repair vs. replaceReal numbers on both sides, including what the R-410A phase-out does to the cost of keeping an old unit alive.
Family-owned since 2006The person who quotes your job is the person you can call about it. That is the whole advantage of not being a franchise.
English, Português, EspañolUseful when the owner, the tenant and the kitchen staff do not all speak the same language.

Good questions. Straight answers.

Do you offer commercial HVAC maintenance contracts?+

Yes. Most of our commercial customers are on a scheduled maintenance agreement — typically two or four visits a year depending on the equipment and how hard it runs. Every visit ends with a written report and photos you can forward to an owner or board.

How fast can you get to a commercial breakdown?+

Sites on a maintenance agreement get priority scheduling, and we do our best to reach any commercial breakdown the same day. Call (407) 398-5929 and tell the office it is a commercial system down — that moves it up the board.

Can you work after hours or before we open?+

Yes. Restaurants, retail and offices usually cannot lose a floor mid-shift, so we schedule shutdowns, changeouts and crane lifts early morning or after close whenever the job allows.

Can you provide a certificate of insurance?+

Yes — we are a Florida certified contractor, license #CAC1818913, licensed and insured. Send us your property's COI requirements and we will have our carrier issue it before we mobilize.

Do you handle rooftop unit replacement and crane lifts?+

We do. RTU changeouts are a regular part of our work: pulling the old unit, curb adapter and any duct transitions, setting and commissioning the new one, and coordinating the crane crew and lift window with the property.

What commercial equipment do you service?+

Rooftop package units, split systems, ductless and mini-split zones, and the ductwork and controls that go with them. We service all major brands, not only what we install.

Do you look after multiple properties for one owner?+

Yes — property managers and owners with several buildings are a big part of who we work for. One contractor, one point of contact, consistent documentation across every site.

What does the R-410A phase-out mean for our rooftop units?+

Existing equipment keeps running, but R-410A is being phased down, so refrigerant is getting more expensive and new equipment ships with different refrigerant. On an older unit with a leak, that changes the repair-versus-replace math — we walk through the numbers with you before you spend anything.

Do you handle new construction and tenant build-outs?+

Yes. We work with builders and general contractors from rough-in through final commissioning, including ductwork for tenant improvements and suite build-outs.
