High-performance, energy-efficient VRV and VRF systems tailored to your building's layout and load — ideal for multi-storey offices, hotels, aged care and mixed-use commercial buildings. We design with your long-term servicing and maintenance schedule in mind, and source equipment from our preferred commercial brands including Daikin, Mitsubishi Heavy Industries and Panasonic.
Even, consistent airflow across all zones for improved comfort, tenant satisfaction and energy efficiency. Our technicians use calibrated measuring equipment to balance supply and return air across floors, meeting rooms and open-plan zones — reducing hot spots, cold pockets and the repair callouts that come from systems running out of spec.
Scalable air-cooled chiller and rooftop package systems for large commercial and industrial applications — warehouses, manufacturing facilities, distribution centres and multi-tenant office blocks. Each install is backed by our commercial repair service and covered by fixed-price servicing agreements so facilities managers aren't chasing invoices for routine work.
Keep your systems running at peak performance and avoid costly breakdowns with scheduled preventative maintenance plans tailored to your building size and system type. Quarterly and half-yearly servicing keeps manufacturer warranties valid, reduces unexpected emergency repair bills, and catches faults before they become business-stopping failures. Use our troubleshooting guide if your team needs a quick reference between visits.
We've installed and maintained commercial air conditioning systems across a wide range of Sydney industries — offices, retail chains, restaurants and cafés, medical practices, aged care facilities, schools, warehouses, strata buildings and manufacturing sites. Each building has different priorities: tenant comfort for office landlords, food-safe temperature control for hospitality, 24/7 uptime for medical and aged care.
Our commercial team covers all of metropolitan Sydney — from the CBD and Inner West to Parramatta, the Hills District, Sutherland Shire and out to Macarthur and the South West. See our service areas directory for your suburb, or view our recent commercial projects to see the kind of work we handle.
Commercial air conditioning isn't residential at a bigger scale — it's a different discipline. Commercial systems deal with higher occupancy loads, longer runtime hours, compliance requirements around air quality and energy reporting, strict fit-out timelines, and zoning needs that residential systems never encounter. A poorly sized or badly commissioned commercial system costs far more than a residential one, both in running costs and in productivity when it goes down.
That's why our commercial installs include full load calculations, documented commissioning reports, and ongoing preventative maintenance schedules — not just a handover and a handshake. If your business already runs a system we didn't install, we also take over commercial repair and servicing contracts from other providers with no setup fee.
Ongoing Maintenance & Servicing for Commercial Systems
Planned servicing is the single biggest factor in how long a commercial air conditioning system lasts, how much it costs you to run, and how often it lets you down on a trading day. Most commercial breakdowns aren't random — they're preventable faults that weren't caught in time. The next few sections break it down plainly: why commercial systems need planned servicing, what's actually included when we service yours, and the measurable benefits of being on a scheduled agreement. See our preventative maintenance plans if you want to skip straight to the specifics.

Commercial air conditioning runs harder and longer than residential systems — often 10+ hours a day, 5–7 days a week, across multiple tenancies or trading zones. Without planned servicing, minor issues compound fast: dirty coils drop efficiency 15–20%, blocked filters stress compressors, refrigerant pressures drift out of spec, and small electrical faults escalate into full system failures on the hottest trading day of the year.
Manufacturer warranties on commercial equipment — Daikin VRV, Mitsubishi Heavy Industries, Panasonic, ActronAir — also require documented servicing to stay valid. Skipping servicing to save money usually ends up costing 3–5x more in emergency commercial repairs and voided warranty claims. Our preventative maintenance plans are built specifically for commercial duty cycles.
Every scheduled service visit follows the same documented checklist, so nothing gets missed and you have a clear paper trail for warranty, compliance and handover purposes:
If any fault is found during servicing, we quote it on the spot — no surprise invoices. For common issues that come up between visits, the AC troubleshooting guide is a good first-reference for your facilities team.

Businesses on a scheduled service agreement see real, measurable differences versus ad-hoc servicing:
We tailor service agreements to your building — quarterly for high-occupancy sites like medical practices, aged care and hospitality, half-yearly for standard offices, and custom schedules for mixed-use and industrial sites. See our pricing and costs page for servicing plan ranges, or get in touch and we'll walk through your building and quote a plan that fits.
Most commercial systems need servicing every 3 to 6 months, depending on how hard the system runs and the type of building. Quarterly servicing suits high-occupancy sites like medical practices, aged care, hospitality and retail where hygiene and uptime matter. Half-yearly servicing covers standard offices and strata buildings. Industrial and manufacturing sites often need monthly filter checks on top of quarterly deep servicing. Skipping scheduled servicing typically voids manufacturer warranties on Daikin, Mitsubishi Heavy Industries, Panasonic and ActronAir commercial equipment. See our preventative maintenance plans for full scheduling options.
Yes. We work with strata managers, property managers and business owners to look after ongoing air conditioning maintenance across single sites and multi-building portfolios. We can take over existing maintenance schedules, set up new service plans, and provide clear reports after each visit so committees and landlords can see exactly what has been done.
Yes. Jays Air Conditioning holds current ARCtick refrigerant handling licences and electrical licences, and we maintain up to $20 million in public liability insurance. That means we can safely work in commercial buildings, shopping centres and strata common areas while meeting your WHS and contractor compliance requirements.
Commercial servicing is typically priced per visit or on an annual contract. A single-visit service for a small office split-system setup starts around $220 per unit, while quarterly servicing contracts for larger commercial buildings (VRV systems, rooftop packages, multi-zone ducted) are quoted per site after a walkthrough. Annual contracts almost always work out cheaper than ad-hoc servicing, and include priority booking during heatwaves. See our pricing and costs guide for detailed ranges, or contact us for a site-specific quote.
We provide written maintenance reports after each commercial service, including any issues found and recommended follow-up works. Our servicing is aligned with Australian standards and guidelines such as AS/NZS 3666 and AIRAH DA19, which helps owners and managers demonstrate they are meeting their HVAC maintenance obligations.
We regularly service air conditioning in small offices, medical and dental clinics, childcare centres, gyms, restaurants, retail stores and strata common areas across Sydney. If your building has split systems, ducted units, VRF/VRV or rooftop package units, we can set up a maintenance plan to suit your usage and budget.
Yes. For our regular commercial clients, we offer priority breakdown attendance with after-hours and weekend support available when loss of cooling or heating would impact trading or tenant comfort. We will discuss response time targets with you up front so you know what to expect if a system fails outside normal business hours.
Yes. We can review your current maintenance schedule, recent service reports and any outstanding issues, then step in as your ongoing contractor with minimal disruption. Our priority is to keep your systems reliable and compliant while giving you clearer communication and better follow-up than you may be getting now.
Yes — we take over commercial servicing and repair contracts from other providers regularly, with no setup fee. We run a full walkthrough of every system, review the previous service history (if available), and flag any deferred issues before we quote the ongoing agreement. You get a clean baseline, documented service records, and a single point of contact across every AC system in your building.
For businesses on a service agreement, we guarantee priority booking — typically 2-hour CBD response and 4-hour metro response during trading hours for genuine emergency repairs. Response windows extend during peak heatwaves when demand spikes, but service-agreement clients are always moved to the front of the queue. Non-contract customers are booked as capacity allows, which during summer peak can mean 3–5 days — one of the biggest reasons businesses move to a scheduled service agreement.
Yes — we service every major commercial brand installed in Australia, including Daikin VRV/VRF, Mitsubishi Heavy Industries, Mitsubishi Electric, Panasonic, ActronAir, Fujitsu, Toshiba and LG. We’re a licensed and ARCtick-refrigerant-certified commercial service provider. For system-specific capabilities and brand strengths, see our preferred brands page. If you’re running older or less common equipment, we still service it — call and we’ll confirm parts availability.
We cover all of metropolitan Sydney for commercial installations, servicing and repairs — CBD, Inner West, Parramatta, the Hills District, North Shore, Eastern Suburbs, Sutherland Shire, Macarthur, South West Sydney and Greater Western Sydney. Our vans are on the road across Sydney every day. See our service areas directory for your specific suburb — if it’s not listed, call us anyway, we almost certainly cover it.
