Every commercial call includes diagnosis, an upfront price, the repair itself, and a documented test before we leave. Parts are quoted separately from labor so you can see exactly where the money goes. Maintenance contracts bundle the routine work at a flat annual rate.
We check refrigerant pressures with manifold gauges, amp draw with a clamp meter, airflow at the registers, and the condition of filters, coils, and drain lines. You get a written summary of what failed and why, not just a repair bill.
The price you approve is the price you pay. Parts and labor are broken out, and if we find something else while we are in the unit, we quote it separately and let you decide. No surprise charges appear on the final invoice.
We recover, weigh, and recharge refrigerant to the manufacturer's spec using a recovery machine and refrigerant scale. R-410A and R-32 systems both get handled by EPA Section 608 certified technicians, with the charge documented on your service record.
Clogged PVC drain lines and leaking flex duct cause more Orlando commercial callbacks than any electrical fault. We flush drains, repair duct insulation and sheet metal joints, and verify airflow so the unit is not fighting a leaky distribution system.
After the repair, we run the system under load for 20 to 30 minutes and record supply and return temperatures. If the numbers are not where they should be, we keep working. You get the readings in writing.
Commercial HVAC in Orlando is the design, repair, and maintenance of the heating and cooling equipment that keeps a business running, from 5-ton rooftop packaged units to multi-zone split systems and ductless heads. That means refrigerant charge checks with manifold gauges, compressor and contactor testing with a clamp meter, drain line clearing, duct leakage repair, and thermostat calibration on Honeywell, Nest, and Ecobee controls. It also means knowing when a failing capacitor or blower motor is worth replacing and when a 15-year-old unit has to go.
Orlando buildings work their cooling systems hard. Summer heat indexes above 100 degrees, near-daily afternoon thunderstorms, and year-round humidity push equipment past what a homeowner system ever sees. That is why a business HVAC service Orlando owners can call at 6 a.m. before opening matters more here than in most markets. We see clogged PVC drain lines, frozen evaporator coils, and refrigerant leaks on rooftops from Winter Park to Kissimmee, and we fix the cause, not just the symptom.
You call, we show up, we fix it. Here is exactly what happens from first ring to final test, so you know what to expect before we ever pull into your lot.
Schedule
Call or book online — a real human picks up and confirms a 2-hour arrival window.
Diagnose
Licensed tech inspects on-site, then walks you through the cause and your options.
Fix
The job is completed to code and done right the first time — no shortcuts, no surprises.
Guarantee
Every job backed by a written workmanship warranty — and we stand behind it.
Manifold gauges
Used on every refrigerant diagnosis to read suction and liquid pressures and compare them against the manufacturer's charging chart for the current outdoor temperature.
Recovery machine and refrigerant scale
We recover refrigerant before opening a circuit and weigh the charge back in to the ounce. R-410A and R-32 systems both get handled this way, and the weight goes on your service record.
Clamp meter and multimeter
Amp draw on compressors, blower motors, and condenser fans tells us whether a motor is failing before it quits. We also use the multimeter to test capacitors and contactors under load.
Electronic leak detector
Finds refrigerant leaks in copper line sets, brazed joints, and coil circuits that a visual inspection would miss. We confirm every hit with a pressure test before repairing.
Duct cleaning vacuum and fin comb
The vacuum clears debris from duct runs during cleaning and repair work, and the fin comb straightens bent condenser coil fins so airflow across the coil is not restricted.
Tube cutter, flaring tool, and swaging tool
Used for copper line set work when we repair or replace refrigerant lines. Clean cuts and properly formed flares are what keep a repaired joint from leaking again next season.
EPA Section 608 refrigerant handling
Every technician who touches refrigerant holds EPA Section 608 certification. That means recovery before repair, no venting, and a documented charge weight on every job. It is the law, and it is also how you know the repair will hold.
ACCA load and airflow standards
When we size a replacement or diagnose an airflow complaint, we work to ACCA standards rather than rules of thumb. That means measuring static pressure and register airflow instead of guessing that a bigger unit will fix a comfort problem.
NATE-certified diagnostics
Our technicians hold NATE certification, which requires passing industry exams on refrigeration, electrical, and airflow. It shows up on the job as a systematic diagnosis instead of parts-swapping until something works.
OSHA-compliant rooftop safety
Commercial work means ladders, roof edges, and electrical panels. We follow OSHA safety compliance on every call, which protects our techs and keeps your building's insurance and liability clean.
01
What we do: We dispatch the nearest truck, diagnose on arrival, and repair on the spot when the part is on the truck. If it is a compressor or a part we do not carry, we set up temporary cooling so the dining room stays usable while we source the replacement.
→ Most restaurants are back to full cooling the same night, and nobody cancels a reservation over a hot dining room.
02
What we do: We measure airflow at the registers, check the zone damper, and inspect the duct run. The usual culprit is a leaking flex duct or a stuck damper actuator, both of which we repair on site.
→ The zone holds setpoint again, and the building stops running the compressor overtime to compensate for one hot corner.
03
What we do: We pull the service history, test the compressor and heat exchanger, and price both paths. If the unit has life left, we repair it. If it does not, we quote a replacement sized to ACCA standards and pull the permit.
→ You get a clear number for each option and a decision you can defend to ownership, instead of a tech pushing the more expensive choice.
04
What we do: We schedule commercial HVAC maintenance Orlando visits before 8 a.m. or after 6 p.m., work unit by unit, and leave a service record for each piece of equipment. Filters, coils, drains, and electrical checks all get done in one pass.
→ Tenants never see a disruption, and the building enters summer with clean coils and clear drains instead of waiting for a breakdown.
Orlando commercial cooling works harder than almost anywhere in Florida. Summer heat indexes push past 100 degrees, afternoon storms roll through most days from June to September, and humidity stays high enough that drain lines and coils foul faster than in drier markets. Rooftop units take direct sun all day, which shortens capacitor and contactor life. Building stock matters too: 1940s brick storefronts downtown often have undersized returns, while newer Lake Nona construction uses zoned systems that need damper and thermostat work rather than brute-force cooling. Florida code requires permitted, code-correct installation work, and we pull those permits. If you are comparing commercial AC service Orlando Florida providers, ask how they handle storm-season scheduling, because that is when the real test comes. We run extra crews through the summer and keep emergency slots open for buildings that cannot close.
Downtown Orlando
Older brick buildings with limited mechanical space. Rooftop access is often tight, and return air paths are frequently undersized, so airflow measurement matters more than unit size.
Lake Nona
Newer office and medical construction with zoned systems and building automation controls. Damper actuators and thermostat programming cause more calls here than mechanical failures.
Winter Park
A mix of historic retail and newer mixed-use buildings. Many properties run two or three smaller units instead of one large rooftop, so maintenance contracts are priced per unit.
Kissimmee
Hospitality and short-term rental properties with heavy occupancy swings. Equipment runs near-constant in peak season, and filter changes need to happen more often than the standard twice-a-year schedule.
Sustained summer heat indexes above 100 degrees
Condenser coils run hotter, compressors pull higher amps, and capacitors fail sooner. We see a clear spike in no-cool calls from June through September, which is why we staff extra summer crews.
Near-daily afternoon thunderstorms from June to September
Power surges and brownouts damage contactors, control boards, and compressors. Surge protection on commercial units is one of the cheapest upgrades an Orlando building owner can make.
Year-round humidity above 70 percent
Condensate production stays high all year, so PVC drain lines grow algae and clog. Twice-a-year drain flushing prevents the ceiling damage we see most often in commercial buildings.
Direct rooftop sun exposure on packaged units
Units baking in full sun lose capacity and age faster than shaded equipment. Coil cleaning and correct refrigerant charge matter more here than in cooler climates.
Most commercial breakdowns trace back to a handful of failures. Here are the ones we see most in Orange County buildings, and what happens if they get ignored.
Problem
A slow leak means the system runs longer, pulls more amps, and eventually freezes the evaporator coil. Cooling capacity drops, the compressor overheats, and a $400 repair turns into a $3,000 compressor replacement.
Our Fix
We locate the leak with an electronic leak detector, repair the copper line set or joint, pressure test, and recharge to spec with a refrigerant scale. You get the charge weight documented so the next tech knows the baseline.
Problem
Orlando humidity feeds algae growth in PVC drain lines. Once the line clogs, condensate backs up into the pan, overflows, and stains ceiling tiles or shorts out electrical components. We have seen it take down a whole retail ceiling grid.
Our Fix
We clear the line, flush the pan, and install a float switch if the unit does not have one. On maintenance contracts we flush drains twice a year, which is the single cheapest way to prevent water damage in an Orlando commercial building.
Problem
These are the most common no-cool calls we run. The unit hums, the fan does not spin, and the building heats up fast. Left alone, a failed capacitor can take the compressor with it.
Our Fix
We carry capacitors and contactors on every truck. Most of these calls are diagnosed and repaired in a single visit, usually within two hours of arrival, and the building is back to temperature before the afternoon peak.
Problem
Leaking flex duct and separated sheet metal joints dump conditioned air into the plenum. The front of the store stays cool while the back bakes, and your electric bill climbs because the unit runs longer to compensate.
Our Fix
We inspect the duct runs, seal leaking joints, replace failed flex duct and duct insulation, and rebalance airflow. Most buildings see supply air temperatures drop several degrees at the problem registers after the repair.
Commercial equipment fails on its own schedule, usually the worst one. Here is what you get when you put our team on your building.
Same-Day Commercial Repairs
Most commercial HVAC repair Orlando FL calls get a technician on site the same day, and emergencies get priority dispatch. We stock capacitors, contactors, and common blower motors on the truck, so a capacitor failure at 9 a.m. is often a cool building by early afternoon instead of a lost day of business.
Downtime You Can Plan Around
We schedule commercial HVAC maintenance Orlando visits before opening or after close so your customers never see a ladder in the lobby. A standard maintenance call runs 90 minutes to two hours per unit, and we tell you the window up front so you can staff around it.
Honest Repair-or-Replace Calls
If a compressor is gone on a 16-year-old rooftop unit, we will tell you straight instead of selling you three more repairs. We price both paths, show you the numbers, and let you decide. No pressure, no upsell scripts, no surprise line items on the invoice.
One Crew for Every Unit
Rooftop packaged units, split systems, mini-splits, and heat pumps all get handled by the same licensed team. That means one number to call, one set of records for your building, and no juggling three contractors who each blame the other when something fails.
Google ★★★★★4.9
Called them for a rooftop unit that quit on a Saturday. Tech was on site in under two hours, found a bad contactor, and had us cooling before close. Price matched the quote. We moved all three of our Orlando properties onto their maintenance plan.
Yelp ★★★★★4.8
They diagnosed a refrigerant leak another company missed and repaired the line instead of pushing a full replacement. Supply air was eight degrees colder at the registers afterward. Honest work, fair price, and they left the readings in writing.
BBB ★★★★★4.9
We manage a Winter Park retail building and needed maintenance scheduled outside business hours. They worked before opening, serviced all four units, and left a record for each one. Zero tenant complaints, and no breakdown calls since.
Google ★★★★★5.0
Our Lake Nona office had one zone that never cooled. They found a separated duct joint, fixed it, and rebalanced the airflow. The zone holds setpoint now and we never had to replace the system. Straight answers from the first phone call.

Real experiences from customers who chose our Commercial HVAC services.
“Our rooftop unit died on a Friday lunch rush in July. They had a tech on the roof within two hours, found a failed contactor, and had us cooling again before the dinner crowd. The invoice matched the quote exactly. We signed a maintenance contract the next week and have not had a surprise breakdown since.”
Marcus D.
Restaurant Owner, Downtown Orlando
“We manage three office buildings and used to juggle two different contractors. Orlando HVAC Air Conditioning took over all of them, and now one crew handles every unit. They schedule maintenance before our tenants arrive, and the service records they leave make my reporting easy. Response time on emergencies has been under three hours.”
Priya S.
Property Manager, Lake Nona
“A refrigerant leak had one of our two units short-cycling for weeks. Their tech found it with a leak detector, repaired the line, and weighed the charge back in with a refrigerant scale. Supply air dropped eight degrees at the registers. Straight answers, fair price, no upsell on a replacement we did not need.”
