What Our Customers Say
Don’t just take our word for it. Here’s what our customers have to say.
Questions before you book?
01Which air conditioning system is right for my Brisbane home?+
Room size is only the starting point. Ceiling height, insulation, glazing, sun exposure and how you use the space also affect capacity. A split system suits individual rooms, while a ducted system can serve several rooms with zoning. Ask for a site assessment before choosing a model.
02Do you install both split and ducted air conditioning?+
DEZ Group provides installation enquiries for split systems, multi-split and ducted air conditioning. Tell the team about your property, rooms and preferred brand so they can confirm a suitable system and installation scope.
03Why is my air conditioner running but not cooling?+
Check the remote is set to cool, the target temperature is below the room temperature and the accessible filters are clean. Restricted airflow, a refrigerant leak or an electrical fault may need a qualified technician. Do not open electrical panels or handle refrigerant yourself.
04How often should an air conditioner be serviced?+
Follow the manufacturer’s schedule and clean accessible filters as instructed. Usage, dust, pets and commercial operating hours can change the maintenance needs. Ask our team to recommend a service interval for your system and environment.
05Are online bookings confirmed immediately?+
No. The form sends a booking request. The team must contact you to confirm the appointment, service area and any applicable call-out or assessment charges.
