The Importance of Regular AC Maintenance

Air conditioning systems are an investment, and as a home or business owner the last thing you want to be doing is worrying about maintenance or experiencing a complete breakdown. Our maintenance program is for regular servicing of both domestic and commercial air conditioning units.

The first step is to carry out a comprehensive assessment and service of your air conditioning systems. Following this, we can design a customised contract specifically for you. Contracts go for 12 month, and automatically roll over unless we are advised otherwise in advance.

You will receive a reminder prior to each scheduled maintenance visit, and your system details will be logged on our database, so we have a record of any issues or repairs which have been carried out.

Regular Air Conditioning Maintenance will Benefit You by:

  • Maintaining healthy air quality through removing dust, allergens, and dirt etc.
  • Improving the AC system reliability and energy efficiency
  • Reducing the likelihood of the system developing faults, or breaking down
  • Keeping operating costs to a minimum and maintaining peak performance

Hi Wade, I am very happy with the job done by your installer, Louis and his assistant, Dave. Equally very happy with your electrician, Robbie and his assistant. Their work is highly commendable. Your company exudes professionalism and efficiency to a high degree in terms of coming on the appointed date and time, installing 2 air conditioners, checking on the wiring of the 4 other air conditioners and finishing the work in just a day. This is the second time I hired your services - Firstly my home and secondly, my son's home. In both cases you have met and exceeded our expectations. All the best!

The entire ACG team are brilliant in every aspect of customer service experience. Ease of inquiries, friendly and responsive online response and phone calls. The team of Ibrahim and Jake accompanied by their boss Wade came to my home this afternoon to ensure they can complete the last job for the day. Despite running behind schedule, the guys were courteous, hard working and takes great pride in their quality workmanship and respectful of customer's home. Highly recommended and trusted company. Thank you for a positive experience.
