Frequently Asked Questions
Answers to common questions about our HVAC services, service area, and how we work.
What areas does DC Air service?
DC Air is based in Holland Park West, Brisbane and primarily services all of South East Queensland - including Brisbane, Gold Coast, Sunshine Coast, Ipswich, Logan, Redlands, and Moreton Bay. For larger commercial projects, we can also travel across regional Queensland.
Do you handle both commercial and residential HVAC?
Yes. DC Air provides full HVAC solutions for commercial, industrial, and residential clients. Our commercial services include design, engineering, installation, and ongoing maintenance for offices, retail, warehouses, and multi-tenancy buildings. Residential services cover ducted systems, multi-zone air conditioning for new builds, renovations, and larger homes.
What is a HVAC service contract?
A service contract is a planned preventative maintenance agreement. DC Air schedules regular inspections and servicing of your HVAC systems to catch issues early, extend equipment life, reduce energy costs, and maintain compliance with Australian standards. Service contract clients also receive priority emergency response.
Do you attend breakdowns?
Yes, for our clients. Breakdown response is part of looking after our maintenance and service contract clients, who are attended first. We do not run a public after-hours call-out line; new enquiries are handled during business hours (Monday to Friday, 7am to 4pm).
Is DC Air licensed and insured?
Yes. DC Air is fully QBCC licensed for mechanical services, ARCtick licensed for refrigerant handling, and carries comprehensive public liability insurance and WorkCover Queensland workers compensation. Certificates of currency are available on request.
What brands do you install and service?
We supply, install, and service all leading air conditioning brands including Daikin, Mitsubishi Electric, Fujitsu, Panasonic, Mitsubishi Heavy Industries, LG, Samsung, ActronAir, Carrier, and Toshiba. We recommend the right system for your space and budget - not the biggest commission.
What is the difference between ducted and split system air conditioning?
A split system has an indoor and outdoor unit and cools one room or area. A ducted system uses a central unit with ductwork running through your ceiling to cool multiple rooms or zones from a single system. Ducted systems offer whole-home comfort and are more common in larger homes and commercial buildings. DC Air can advise on which suits your property.
Can you service HVAC systems that another company installed?
Absolutely. DC Air services and maintains all major HVAC brands and systems regardless of who installed them. We often take over maintenance for systems that were previously neglected or underserviced, and can provide a full condition assessment before recommending any work.
How long does a typical HVAC installation take?
It depends on the scope. A residential split system can be installed in a day. A ducted system for a new home typically takes 2 to 5 days. Commercial installations vary significantly based on building size and complexity - from a few weeks for smaller fitouts to several months for large-scale projects. DC Air provides detailed timelines as part of every quote.
What should I expect during a HVAC service visit?
A DC Air technician will inspect your system, clean filters and coils, check refrigerant levels, test electrical connections, verify thermostat operation, and assess overall system performance. You will receive a written service report documenting the condition of your equipment and any recommended actions.
Do you provide written quotes?
Yes. Every DC Air quote is provided in writing with a detailed breakdown of scope, equipment, labour, and any applicable warranties. We believe in transparent pricing with no hidden extras. For commercial projects, we can also provide staged payment schedules in line with QBCC requirements.
What warranty do you offer on installations?
DC Air provides a workmanship warranty on all installations, in addition to the manufacturer warranty on equipment (which typically ranges from 5 to 10 years depending on the brand and model). Our warranties operate alongside your statutory rights under Australian Consumer Law.
How do I know if my HVAC system needs replacing?
Common signs include frequent breakdowns, rising energy bills, uneven cooling, excessive noise, or the system being over 15 years old. DC Air can perform a condition assessment and provide honest advice on whether a repair or replacement makes more sense for your situation. We will never recommend a replacement when a repair will do the job.
How do breakdown callouts work?
Service contract clients receive priority breakdown response as part of their agreement. Callouts cover troubleshooting and diagnosis - if parts are needed, we quote the repair separately so you know exactly what you are paying for.
