Air Conditioning Compliance Victoria 2026: Homeowner Must Know

Introduction: Why Air Conditioning Compliance Matters More Than Ever in 2026

Victoria is in the middle of a major energy transition. The state government is phasing out gas appliances, tightening rental property standards, and funding the replacement of inefficient heating and cooling systems through the Victorian Energy Upgrades (VEU) program. For Melbourne and Victorian homeowners, getting a new reverse cycle air conditioner installed in 2026 is one of the smartest energy and financial decisions available — but the installation must be done correctly.

Air conditioning compliance in Victoria is governed by multiple layers of regulation: the Victorian Building Authority (VBA) regulates who can carry out the installation work; Energy Safe Victoria (ESV) regulates the electrical side; the Environment Protection Authority Victoria (EPA Victoria) regulates noise from your outdoor unit; the Australian Government’s Equipment Energy Efficiency (E3) program sets minimum energy performance standards; and the Victorian Government’s electrification standards are reshaping the obligations of both homeowners and landlords from 2027.

This guide brings all of those regulatory requirements together in one place, drawing exclusively on official government sources, so Melbourne and Victorian homeowners know exactly what compliance involves, what certificates they must receive, what their outdoor unit is legally allowed to do, and what is changing for rental properties from March 2027.

“Installing an air conditioning system is not a do-it-yourself job — you must use a suitably licensed person, otherwise you are putting yourself and your family at risk.” — Energy Safe Victoria and Victorian Building Authority, joint fact sheet

1. Who Can Legally Install an Air Conditioner in Victoria?

This is the most important compliance question. Under the Plumbing Regulations 2018 and the Building Act 1993 (Vic), only licensed and registered practitioners can carry out air conditioning installation work in Victoria. The two bodies that regulate these practitioners are:

The Victorian Building Authority (VBA) — also trading as the Building and Plumbing Commission (BPC) — which registers and licences refrigerated air conditioning plumbers
Energy Safe Victoria (ESV) — which licences electrical workers and Registered Electrical Contractors

The VBA and ESV issued a joint fact sheet confirming these requirements, available at energysafe.vic.gov.au. The key licensing requirements for a compliant installation are:

Role	Required Licence / Registration	Issuing Authority
Refrigerated air conditioning installer	VBA registration in the Refrigerated Air-conditioning class (a main class of plumbing work under the Plumbing Regulations 2018)	Victorian Building Authority (VBA / BPC)
Refrigerant handling	Refrigerant Handling Licence (RHL) — also called an ARCTick licence for systems using ozone-depleting refrigerants	Australian Refrigeration Council (ARC) — federal scheme
Electrical connection (new circuit or complex wiring)	Licensed Electrician (A-grade) or Registered Electrical Contractor (REC) registered by ESV	Energy Safe Victoria (ESV)
Electrical connection (simple replacement, same location, equivalent power)	Restricted Electrical Workers Licence (REL) with Refrigeration and Air-conditioning classification	Energy Safe Victoria (ESV)

Source: Energy Safe Victoria / VBA Joint Fact Sheet — Air-conditioning systems: Installation and replacements — energysafe.vic.gov.au

In practice, a new reverse cycle air conditioner installation in Victoria always requires at least two licensed trades working together: a VBA-registered refrigerated air conditioning plumber, and either an A-grade licensed electrician or Registered Electrical Contractor registered with ESV. Climate Green’s installation teams hold all required licences and registrations for every job.

⚠️ Verify Before You Commit You can check a plumber’s VBA registration status at: vba.vic.gov.au — click ‘Find a practitioner’ You can check an electrician’s ESV licence status at: connect.energysafe.vic.gov.au If a tradesperson cannot be verified on either register, do not proceed — their work will not be legal, and you will not receive valid compliance certificates.

2. The Two Compliance Certificates You Must Receive

Under Victorian law, two mandatory compliance certificates must be issued to the homeowner after every air conditioning installation. These are not optional extras — they are legal requirements under the Building Act 1993 (Vic) and the Electricity Safety Act 1998 (Vic).

Certificate 1: VBA Plumbing Compliance Certificate

A Plumbing Compliance Certificate is issued by the licensed plumber who carried out the refrigerated air conditioning work. It certifies that the installation complies with all relevant prescribed plumbing standards.

A compliance certificate must be issued whenever the total value of the work — including materials, appliances, labour, and GST — exceeds $750
The licensed plumber must issue the certificate to the customer within five working days of completing the work
The plumber is also required to lodge the certificate with the VBA within five working days via the VBA360 portal
A Plumbing Compliance Certificate provides a six-year warranty for the installation — as confirmed in a joint statement by VBA CEO Stavros Cialini
A potential purchaser of a property may request copies of compliance certificates — their absence can impact the sale of a property

Certificate 2: ESV Certificate of Electrical Safety (CoES)

An Electrical Safety Certificate — formally called a Certificate of Electrical Safety (CoES) — is issued by the licensed electrician or Registered Electrical Contractor after completing the electrical connection work.

The CoES confirms that all electrical work meets safety standards under the Electricity Safety (General) Regulations 2019
It must be provided to the homeowner upon completion of the work
You can verify an electrician’s licence at connect.energysafe.vic.gov.au before work begins

🚫 If You Don’t Receive Both Certificates — Act Immediately Under Victorian law, you are legally entitled to both a Plumbing Compliance Certificate and a Certificate of Electrical Safety after every air conditioning installation. If your plumber fails to issue or lodge a compliance certificate within 5 working days, you can lodge a complaint with the VBA by calling 1300 067 088. If you were not provided with a CoES, contact Energy Safe Victoria at esv.vic.gov.au. An installation without valid compliance certificates: voids your manufacturer’s warranty on the system; may not be covered by your home and contents insurer; creates legal liability as the property owner; and disqualifies the installation from the VEU rebate program.

3. Noise Rules for Outdoor Units — Environment Protection Regulations 2021

Air conditioner noise is one of the most common neighbour disputes in Victoria. The Environment Protection Authority Victoria (EPA Victoria) administers residential noise regulation under the Environment Protection Act 2017 and the Environment Protection Regulations 2021. Both laws are in force today.

The Legal Framework

Under section 167 of the Environment Protection Act 2017, causing unreasonable noise is an offence. Residential noise is unreasonable if it occurs during prohibited times and can be heard in a habitable room of any neighbouring residence. A habitable room is any room except kitchens, pantries, bathrooms, toilets, laundry rooms, and storage areas — meaning bedrooms, living rooms, and dining rooms all qualify.

A council officer may still assess noise to be unreasonable even outside prohibited times if it has qualities that make it unreasonable — for example, unnecessarily excessive volume or excessive duration.

Prohibited Times for Air Conditioners — Regulation 114 Table

Regulation 114 of the Environment Protection Regulations 2021 divides residential equipment into groups and sets prohibited times. Air conditioners and evaporative coolers used for cooling fall under Group 4:

Equipment Group	Prescribed Equipment	Prohibited Times (cannot be heard in neighbour’s habitable room)
Group 3	Home heaters, central heating, hot water systems, heat pump or split system used for HEATING, vacuum cleaners	Weekdays: before 7am and after 10pm Weekends & public holidays: before 9am and after 10pm
Group 4	Air conditioners, evaporative coolers, split systems used for COOLING	Weekdays: before 7am and after 11pm Weekends & public holidays: before 9am and after 11pm

Source: EPA Victoria — Residential noise, epa.vic.gov.au/residential-noise (Regulation 114, Environment Protection Regulations 2021)

Note the important distinction: when your reverse cycle system is used for heating, it falls under the earlier Group 3 restrictions (after 10pm). When used for cooling, it falls under the more permissive Group 4 limits (after 11pm). The same physical unit is regulated differently depending on whether it is heating or cooling.

The Heat Health Warning Exception

The prohibited times under Regulation 114 do not apply when you run your air conditioner during a Department of Health heat health warning. This exemption specifically applies to air conditioners in the region covered by the heat health warning — currently the Central Forecast Region for Victoria. However, EPA Victoria confirms that a council officer may still assess air conditioner noise as unreasonable during a heat health warning if the noise has qualities that make it unreasonable. The exemption relaxes the prohibited times, not the general standard of reasonableness.

Who Investigates Noise Complaints?

EPA Victoria administers the residential noise regulations and publishes guidance for local government, including the Noise guideline: Assessing noise from residential equipment. However, EPA Victoria does not investigate individual residential noise complaints — this is the role of your local council. The typical process is:

Speak directly with your neighbour — they may be unaware of the issue
If unresolved, the affected person can lodge a formal complaint with the local council
The council investigates and may conduct a noise measurement assessment
If the noise is found to be unreasonable or occurs during prohibited times, the council can require the unit to be relocated or, in serious cases, issue a direction to cease use

4. Refrigerant Compliance — Federal Licensing Requirements

Air conditioning systems contain refrigerant gases that are subject to Australian federal environmental regulation. The management of these gases is governed by the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989 and its regulations, which control the import, export, and handling of ozone-depleting substances and synthetic greenhouse gases.

The Australian Refrigeration Council (ARC) issues Refrigerant Handling Licences (RHL) — also called ARCTick licences. Key requirements under federal law:

Only technicians who hold a current, valid Refrigerant Handling Licence (RHL) from the ARC can legally purchase, handle, and work with refrigerant gases
For systems using ozone-depleting refrigerants, practitioners are additionally required to hold an appropriate ARCTick licence — as confirmed by the VBA on vba.vic.gov.au
Older refrigerants such as R22 (chlorodifluoromethane) are controlled substances under the Act. Licensed technicians are legally prohibited from purchasing or topping up phased-out refrigerants
Electrical work associated with any refrigeration installation — including air conditioning — must still be carried out by a separately licensed electrician, as noted on the VBA website: ‘Electrical licensing/registration or ARC refrigerant handling licence is not a substitute for a VBA licensing or registration’

5. Minimum Energy Performance Standards (MEPS) — Federal Energy Efficiency Law

Every air conditioning system sold or supplied in Australia must comply with Minimum Energy Performance Standards (MEPS). These standards are part of the Equipment Energy Efficiency (E3) Program — a joint initiative of the Australian Government, all states and territories, and the New Zealand Government.

The legal basis for MEPS in Australia is the Greenhouse and Energy Minimum Standards (GEMS) Act 2012 and the relevant GEMS Determinations for specific product types. The E3 Program is managed by the GEMS Regulator in conjunction with the E3 Committee, which includes representatives of Commonwealth, state, and territory governments.

MEPS limits the energy an appliance can use to complete a specified task — setting a minimum standard of energy performance that must be met before an air conditioner can be legally supplied in Australia
Air conditioners — including non-ducted, ducted, and multiple split systems — are explicitly covered by MEPS requirements
All regulated products must carry an Energy Rating Label in addition to meeting MEPS thresholds
Systems that do not meet MEPS cannot be legally sold or installed in Australia
Under the VEU program, all systems must additionally meet the energy efficiency criteria set out in the ESC approved product register — which goes beyond baseline MEPS to require higher-performing systems for rebate eligibility

Source: energysafe.vic.gov.au — Energy efficiency; energyrating.gov.au — About the E3 Program; GEMS Act 2012

Any grey market or parallel-imported air conditioning system not sourced through an authorised Australian distributor may not carry valid MEPS compliance. Systems without MEPS compliance cannot be legally installed and will not qualify for VEU program discounts. Climate Green sources all systems through authorised Australian distributors with full MEPS compliance.

6. Rental Properties: Victoria’s New Minimum Standards from March 2027

If you own a rental property in Victoria — or if you are a tenant — the compliance landscape is changing significantly from March 2027. The Victorian Government has introduced phased minimum energy efficiency standards for all rental homes, building on existing minimum standards that came into effect in 2021 and the 2-star heating standard introduced in 2023.

The official Victorian Government source is energy.vic.gov.au/households/electric-and-efficiency-standards-for-buildings/energy-efficiency-for-rental-properties-in-victoria, which sets out the complete timeline.

What the Victorian Government Has Confirmed — The Phased Timeline

Date	Requirement	Support Available
1 March 2027	When a gas heating or hot water appliance breaks and cannot be repaired, it must be replaced with a heat pump water heater or an efficient electric reverse cycle air conditioner (RCAC) in the main living area	VEU discounts
1 March 2027	At the start of a new lease (or conversion to periodic lease): energy-efficient cooling must be installed in the main living area	VEU discounts
1 March 2027	At the start of a new lease: ceiling insulation required where none currently exists	VEU discounts (expected from 1 Jan 2027)
1 March 2027	At the start of a new lease: 4-star rated showerheads must be installed	VEU discounts
1 July 2027	At the start of a new lease: draught proofing must be installed on external doors, windows and wall vents	VEU discounts
1 July 2030	Efficient electric cooling must be installed in the main living area of ALL rental homes — regardless of whether a new lease has commenced	VEU discounts

Source: energy.vic.gov.au — Energy efficiency for rental properties in Victoria (February 2026 update); energy.vic.gov.au — New electrification and efficiency standards and regulations for Victorian buildings

Exemptions apply where compliance is impractical or would involve disproportionate cost — for example, in some apartment buildings where ceiling space is shared property, or where heating and hot water are supplied by a centralised system. There is also an exemption from draught proofing requirements where open-flued or flueless gas appliances are present, to ensure occupant safety.

The Financial Case for Acting in 2026

The Victorian Government’s own data makes a compelling case for landlords to upgrade before these deadlines rather than waiting:

Energy efficient houses in Melbourne are achieving up to $197,000 more than non-energy efficient houses, while energy efficient units are averaging $95,000 more — Domain Sustainability Report 2025, cited by energy.vic.gov.au
Installing a new heating and cooling system meeting the new standards is expected to save renters $215 per year off their energy bills — reducing tenant turnover and improving rent stability for landlords
The VEU program provides discounts for eligible upgrades including replacing gas space heaters with reverse cycle air conditioners and replacing gas hot water heaters with heat pump water heaters
The VEU program has been extended through to 2045, confirming ongoing support for energy efficiency upgrades

New Buildings from January 2027: All-Electric Requirement

Beyond rental properties, the Victorian Government has also confirmed that from 1 January 2027, all new residential buildings must be built as all-electric. Building electrification regulations will prohibit a relevant building surveyor from issuing a building permit for the construction of a building that includes a new gas connection. The installation of any gas appliance — including cooking, space heating, and water heating — during construction of a new building will be prohibited from this date.

The Victorian Government estimates that new all-electric homes save approximately $990 per year compared to a gas equivalent, or $1,920 per year when combined with rooftop solar.

7. The VEU Program: Rebates for Compliant Air Conditioning Upgrades

The Victorian Energy Upgrades (VEU) program — administered by the Essential Services Commission (ESC) — provides upfront discounts for energy efficiency upgrades including the installation of reverse cycle air conditioners. The program has been in operation since 1 January 2009 and is now legislated through to 2045.

For reverse cycle air conditioning, the VEU program applies where an inefficient gas space heater or inefficient electric heater is being replaced with an approved, energy-efficient reverse cycle system. Key VEU requirements for air conditioning upgrades:

The property must be located in Victoria and must be at least 2 years old
The installed product must appear on the ESC’s approved product register under the relevant activity category
The installation must be carried out by a VEU-accredited provider
From 31 March 2025, all applicable space heating and cooling products installed under the VEU program must carry a minimum 5-year warranty against defects from the date of installation, purchase, or supply — as confirmed by the ESC
Renters are eligible to access many VEU discounts, though some upgrades including heating and cooling require landlord approval — as noted at energy.vic.gov.au
The VEU discount is applied directly at invoice by the accredited provider — no homeowner application or claim form is required

Source: energy.vic.gov.au — Victorian Energy Upgrades for homes; Essential Services Commission — VEU program requirements

The VEU program is expected to save 37 million tonnes of greenhouse gas emissions for Victoria between 2022 and 2027 — as confirmed by energy.vic.gov.au. Climate Green is a VEU-accredited provider and handles all paperwork, product eligibility, and rebate lodgement on your behalf.

8. Do You Need a Building Permit?

For most standard residential air conditioning installations, no building permit is required under the Building Regulations 2018 (Vic). However, the installation must always be completed by appropriately licensed trades, and specific situations may trigger additional requirements.

Installation Scenario	Building Permit Required?	Notes
Standard split system — new installation	No, in most cases	Installation must still be by licensed trades (VBA + ESV)
Ducted reverse cycle system — new installation	Possibly — check with your council	Some councils require a permit for penetrations to external walls or roof
Direct replacement of existing system (same location, equivalent power/current)	No, in most cases	Electrical work can be done under a Restricted Electrical Workers Licence (REL) in this scenario
Heritage-listed property	Check with your local council	External unit placement may require heritage permit
Strata or owners corporation property	Check with your owners corporation	Body corporate approval is typically required before installation
Commercial property	Often yes — check with your council	Building permit requirements differ for commercial buildings

If you are unsure whether a building permit applies to your specific property and installation type, Climate Green will advise you during your free property assessment.

Frequently Asked Questions

Can I install a split system air conditioner myself in Victoria?

No. Under Victorian law, air conditioning installation is not a DIY task. The Victorian Building Authority (VBA) requires a registered refrigerated air conditioning plumber for all mechanical installation work, and Energy Safe Victoria (ESV) requires a licensed electrician or Registered Electrical Contractor for all electrical work. Self-installation is illegal, voids the manufacturer’s warranty, and disqualifies the installation from VEU rebates.

What if my installer does not provide compliance certificates?

You are legally entitled to both a Plumbing Compliance Certificate and a Certificate of Electrical Safety. The licensed plumber must issue and lodge the Plumbing Compliance Certificate within five working days of completing work on any job valued above $750. If your plumber fails to do so, you can lodge a complaint with the VBA by calling 1300 067 088. For missing electrical certificates, contact Energy Safe Victoria at esv.vic.gov.au.

What are the noise rules for air conditioners in Victoria?

Under Regulation 114 of the Environment Protection Regulations 2021, air conditioners used for cooling (Group 4) must not be heard in a neighbour’s habitable room on weekdays before 7am or after 11pm, or on weekends and public holidays before 9am or after 11pm. Air conditioners used for heating (Group 3) have an earlier prohibited time of 10pm. During an official Department of Health heat health warning, the prohibited times are suspended for the affected region. Noise complaints are investigated by local councils, not EPA Victoria directly.

Do I need a building permit to install an air conditioner?

For most standard residential split system installations, no building permit is required. However, if you are in a heritage area, strata complex, or the installation involves significant structural work, you should check with your local council or owners corporation before proceeding.

What is changing for rental properties from March 2027?

From 1 March 2027, Victorian landlords must replace failed gas heating or hot water systems with efficient electric alternatives (heat pump or reverse cycle air conditioner). At the commencement of any new lease from 1 March 2027, landlords must provide energy-efficient cooling in the main living area, ceiling insulation where absent, and 4-star showerheads. From 1 July 2030, efficient electric cooling must be installed in all rental properties regardless of lease status.

What is MEPS and why does it matter?

MEPS stands for Minimum Energy Performance Standards — part of the federal Equipment Energy Efficiency (E3) Program under the Greenhouse and Energy Minimum Standards (GEMS) Act 2012. All air conditioning systems sold in Australia must meet these standards before they can be legally supplied or installed. Under the VEU program, systems must additionally meet the efficiency criteria on the ESC approved product register. Only source air conditioning systems through authorised Australian distributors to ensure MEPS compliance.

How do I find a licensed air conditioning installer in Victoria?

You can verify a plumber’s VBA registration at vba.vic.gov.au — use the ‘Find a practitioner’ tool. You can check an electrician’s ESV licence at connect.energysafe.vic.gov.au. Climate Green is both VBA-compliant and VEU-accredited — all our installations are completed by VBA-registered refrigerated air conditioning technicians and A-grade licensed electricians, and we provide both mandatory certificates with every installation.
