FAQ
Common questions.
What counts as a commercial HVAC emergency?
No heat in winter, no cooling in a space with customers, staff or temperature-sensitive stock, a rooftop unit down, a suspected gas issue, or anything creating a safety or burst-pipe risk.
Are you actually available overnight and on weekends?
Calls are answered 24 hours a day, seven days a week. Urgent commercial calls are prioritised over routine work.
What should we do before you arrive?
Note what the equipment is doing and any error code on the controller, and make sure roof or mechanical-room access is available. If you suspect a gas leak, evacuate and call your gas utility's emergency line from outside first.
Can you get us running temporarily if a part is not available?
Where it is safe to do so, yes. A temporary measure that keeps a business trading while a part is sourced is often the right call, and we will be clear about what is temporary and what is permanent.
Do you work with property managers and landlords directly?
Yes, including work authorised by a manager on behalf of a tenant. Findings and costs are put in writing so they can be passed on or approved.
Is emergency work priced differently?
Scheduling is what changes with an emergency. Anything beyond the diagnostic is quoted before it is carried out, the same as a planned call.
