What is an HVAC Contractor?

An HVAC (Heating, Ventilation & Air Conditioning) Contractor is a licensed specialist who designs, supplies, and installs climate control systems in residential and commercial buildings. Their work ensures that your property remains comfortable year-round while complying with energy efficiency and ventilation standards.

What does an HVAC Contractor do?

Your HVAC Contractor will complete works according to your agreed scope of works.


Typically, an HVAC Contractor will:

  • Review your floor plan and thermal comfort requirements
  • Recommend suitable systems (e.g. split, ducted, reverse cycle, or multi-head units)
  • Supply and install all HVAC components, including units, ducts, vents, and control panels
  • Coordinate rough-in during the services stage, followed by fit-off after linings
  • Test the system and ensure it complies with Australian Standards (e.g. AS/NZS 1668 and NCC Section J, if applicable)


They ensure your heating and cooling system is efficient, reliable, and ready for occupancy certification.

Tip: Plan Early to Avoid Space Clashes

Plan ahead — some systems require roof space or wall clearances that can impact framing, insulation, and even ceiling heights. Lock it in early to avoid clashes later.

What Makes a HVAC Contractor

Look for someone who:

  • Licensing: Must be licensed for mechanical services and air conditioning installation in your state
  • System knowledge: Should understand your climate zone, energy targets, and insulation setup
  • Installation quality: Ask for photos or references from previous installs with clean ducting and accessible servicing
  • Commissioning & warranty: Ensure the quote includes system testing and a warranty for parts and labour
  • Energy efficiency: Look for contractors familiar with BASIX or NatHERS compliance (where required)

Before You Begin: What You’ll Need Ready

To get quotes from HVAC Contractors, you’ll need:

  • Site address and current floor plans
  • Preferred type of system (if decided)
  • Your energy efficiency report or BASIX Certificate (if available)
  • Details about insulation, ceiling heights, and available roof or wall space
  • Your project timeline for services rough-in and final fit-off

Average Timeframe

For this task, Pros typically provide quotes within 7-10 business days.

When Can I Expect Quotes?

Timeframes often vary based on demand and the type of Pro you're engaging (e.g. a plumber). If additional communication or clarification is needed is needed, the quoting process may take longer.

 

Don't be alarmed if you don't receive quotes or communication from any Build Buddy Pros straight away. Some work is more complex and the Pro may need time to comprehend your documents or scope of work. Depending on the job, there may even be some work required by the Pro before they are able to quote (e.g. a site visit might be required).

 

If the average timeframe indicated here has passed, and you have not received any messages or quotes, please feel free to contact the Build Buddy Expert Guidance and Support team for an update on quoting for this task.

Frequently Asked Questions

  • What’s the difference between split and ducted systems?

    Split systems are ideal for zoning and individual rooms. Ducted systems offer whole-home coverage but need more space and upfront cost.



  • Do I need approval for HVAC installation?

    Typically no, unless it's a multi-dwelling or heritage site — but all work must comply with Australian Standards and be installed by a licensed professional.
