What recent reviews say

Most reviews praise Celsius Air for punctuality, professionalism, and honest pricing. Technicians arrive prepared, complete work cleanly, and follow up weeks later. Stan, Gabriel, Luke, Karina and others are named frequently. Split system and ducted upgrades receive consistent praise for comfort gains.

One complaint: charged $220 for a 15-minute inspection that the customer felt fell short of a proper service. The tension centres on whether a quick roof check counts as a full service visit, though the business states it has standard service fees.

Praised for
  • punctual and professional technicians
  • honest quoting and no hard sell
  • clean workmanship
  • post-job follow-up
  • reliable service across multiple visits
Watch-outs
  • charged full service fee for minimal work
  • lack of transparency on what constitutes a full service

Best for: homeowners upgrading from evaporative to ducted, or managing multiple air-con systems across properties
Think twice if: you want a quick roof check or basic filter change, the $220 service fee may not align with your expectations of value

Strengths

  • Transparent quoting, no upsell pressure
  • Named technicians (Stan, Gabriel, Luke, Karina)
  • Post-job follow-up calls
  • Competitive pricing noted in reviews

Worth knowing

  • Stan, Gabriel, Luke, Karina and Jackson named as technicians
  • Follow-up phone call weeks after installation to check for leaks or issues
  • Split system and ducted evaporative upgrades praised for comfort and zoning setup
  • Customers bring systems from different manufacturers (Daikin, Mitsubishi) to the same team
  • Serve customers across multiple properties (spas in Nedlands and Vic Park mentioned)

Common questions

Do you follow up after installation?
Yes. A few weeks after the job, their office calls to check the system is working and ask about leaks or issues.
What does a $220 general service include?
Standard service includes a roof inspection, filter check and brief testing. Customers report confusion when this is billed at the flat rate for a quick check versus a full hands-on service.
Do you install both split and ducted systems?
Yes. They upgrade from evaporative to ducted, install split systems, and service both types alongside repairs and maintenance.

Strong installation work and honest product advice, but follow-up communication stumbles. Reviewers praise Luke, Mike and crews for clean, thorough jobs and straight talk on ducted and split systems. The main friction point is getting replies after purchase, with multiple reports of unanswered calls and emails left hanging for weeks.

Sanjay and his crew have built a strong track record for prompt, communicative service across residential and commercial work. From quoting through installation to maintenance, customers report technicians arrive on time, explain clearly, leave no mess, and stand behind their work with honest advice and warranty support. Recent jobs span split and ducted systems, emergency repairs, and ongoing servicing. Named installers (Reece, Austin, Ahmed, Steve) and the owner's personal involvement in quotes and repairs build trust. Pricing is called reasonable, and the business backs jobs with follow-up guidance-which matters when people need reliability during Perth's hot spells.
