Commercial HVAC
Same-day where we canFor a business, downtime is the cost — not the repair.
A restaurant with a failed rooftop unit in July is not comparing repair quotes; it is deciding whether to open. Thornquil's commercial work is built around response, documentation, and equipment histories that survive a change of manager — so decisions get made from records rather than from memory.
What you get
What the visit actually includes.
Response scheduling
Commercial calls are dispatched against your operating hours. Work that can happen before opening or after closing is scheduled that way by default.
Equipment register
Every unit inventoried by location, model, serial, age and service history — so the next decision is informed by the last five.
Planned maintenance programmes
Scheduled visits across all units with a single reporting format, filter and belt programmes, and a rolling condition assessment.
Capital planning input
Which units are near end of life, what replacement would cost, and in what order — so replacements land in a budget cycle instead of an emergency.
Reporting a manager can hand upward
Written condition reports per unit, per visit, with photographs and readings. Not a signature on a work order.
How we work
The sequence, every time.
Site walk
Inventory the equipment, the access, the electrical, and the constraints of the space — including when work is actually allowed to happen.
Agree response terms
What counts as urgent for your operation, who can authorise what, and up to what value work can proceed without a call.
Service and document
Every visit recorded against the unit, not the invoice.
Review
A periodic look at cost per unit, repeat failures, and what should be replaced rather than repaired again.
Gulf Coast specifics
Why this work is different here.
Salt air, humidity, attic temperatures and a cooling season that runs most of the year. All four change what fails, how early, and what is worth doing about it.
Rooftop equipment in a marine environment
Coastal rooftops are a hard place to be a condenser. Corrosion of casings, coils and electrical enclosures drives a lot of local commercial failures and is worth inspecting for specifically.
Seasonal occupancy swings
Load in season and load out of season are very different problems. Equipment and controls that suit one can be badly wrong for the other.
Humidity in food service and retail
Latent load from kitchens, door traffic and occupancy is the local challenge more often than sensible cooling capacity is.
Storm season continuity
Knowing which units matter most, how they are secured, and what the restart sequence is after an outage is worth establishing before the season, not during it.
Questions
About commercial hvac
Do you work outside business hours?
Yes. For most commercial clients that is the default rather than the exception, and it is agreed at the start rather than negotiated during a failure.
Can you take on a site with mixed, unknown equipment?
That is the normal starting condition. The first visit is an inventory, which is worth having on its own even if nothing needs fixing yet.
How do you handle multiple sites?
One equipment register, one reporting format, and one point of contact, so comparing sites is possible rather than theoretical.
