   Changing over faulty units

A changeover installation is one where we remove your existing system and install a new one. This process includes the removal and disposal of the existing system, plus electrical modifications for the new system.

residential servicing   New split systems & split ducted

All residential split systems are reverse cycle, inverter and capable of heating and cooling. Simply choose your preferred brand of competitively priced unit (Daikin, Mitsubishi or Panasonic) and have it installed by our fully qualified, licenced and insured in-house team. All electrical and plumbing certificates are provided, plus a 5-year warranty on air conditioning and a 6-year labour warranty.

‘The technician came out to assess my condenser, which had shorted out on a hot day. This was a second opinion, as the first company still hadn’t sent me a diagnosis or a quote three weeks after their visit. The 21 Celsius technician checked it out and explained there was nothing wrong with my system. It was just the load being reduced on a very hot day. He fixed some insulation on a pipe and went on his way. I cannot recommend 21 Celsius highly enough for honesty and competence.’

Here’s how the process works:

  • We’ll visit your site to assess your appliance or system.
  • If you require a service, we’ll carry out a full audit and adjustment of your system. Any issues will be communicated immediately and, if required, we’ll provide you with a solution.
  • If you require a repair, we’ll try to do this on the spot with the parts we carry. If the situation is beyond the scope of instant repair, we’ll provide a repair and/or replacement quote.
  • For all repairs and servicing, you’ll receive photo evidence of our work and a full written report.

‘My old A/C unit broke down and I needed a new one. 21 Celsius installed a new system for me within a week of my initial query. They kept me informed at all times and the installers were prompt, efficient and took care not to leave a mess behind. Highly recommended.’
