Air conditioning questions, answered.
The questions Sunshine Coast homeowners ask us most, answered by the team that does the work.
Ducted air conditioning
What size or capacity air conditioner do I need for my home or multiple rooms?Most Sunshine Coast homes need a ducted system sized at about 70% of the total heat load of the zoned rooms, using roughly 150 W per square metre. That makes 12.5 kW suit about 120 m2 across five zones, and 14 kW suit about 130 m2 across six. A site inspection confirms it.What size ducted air conditioning system is right for my home, and is 12.5kW or 14kW enough?For most Sunshine Coast family homes, yes. A 12.5kW ducted system suits 5 zones, four bedrooms plus an open kitchen, living and dining area. A 14kW suits 6 zones, adding a media room or similar. We size at about 70% of the total room load, then a free site inspection confirms it and fixes the quote.Can ducted air conditioning control temperature per room or run just one zone, such as a bedroom at night?Yes, mostly. A ducted system on the Sunshine Coast is split into zones, and each zone has motorised dampers and its own temperature setting. You can run just a bedroom at night. Every room only gets its own control if it is set up as its own zone, and all zones share one mode, cooling or heating.Can ducted air conditioning be installed if my roof cavity is small or needs ceiling modifications?Often yes. Ducted air conditioning needs enough roof space for the indoor unit, ducts and access, but a small cavity does not always rule it out. On the Sunshine Coast, options include a slimline unit, a bulkhead or a different unit location. A free site inspection confirms what fits before we quote.Cost and finance
How much does it cost to install a split air conditioning system?The cost to install a split air conditioner on the Sunshine Coast depends on the system size, the brand, how many rooms it serves and how tricky the install is. Pipe length, wall type, electrical work and access all change the final figure. A written quote from a licensed installer gives you the real number.How much does air conditioning service cost, including multiple units?The cost of an air conditioning service on the Sunshine Coast depends on the system type, the number of units, how easy they are to reach and their condition. More units cost more in total, but booking them in one visit saves a trip. Tell us how many units and what type for an exact figure.How much does a ducted air conditioning system cost for my house?Most Sunshine Coast homes land between $11,000 and $18,000 installed for ducted air conditioning, and larger homes can reach about $22,000. Where yours sits depends on the size of the system, the number of zones, the duct runs and roof access. Delta Temp does a free site inspection first, then gives you a fixed quote.General questions
Why isn't my air conditioner cooling properly or blowing cold air?An air conditioner that blows warm or weak air on the Sunshine Coast is usually running in the wrong mode, has dirty filters or coils, or has a blocked outdoor unit. If those check out, the cause is often low refrigerant from a leak, a failed fan or compressor part, or a system that is too small.Should I repair or replace my air conditioner?On the Sunshine Coast, repair an air conditioner under about 10 years old if the fault is minor and the repair is a small part of the cost of a new system. Consider replacing one over 12 to 15 years old, or one with a failed compressor or outdoor unit. Get the repair quote before deciding.Should I choose ducted or split air conditioning, and what is the best option for my home?Choose a split system for one room or a small open living area. Choose ducted if you want to cool most of the house from one system, with zones, and you have roof space for ducts. On the Sunshine Coast, the best option depends on your layout, roof space and how you use each room.Why is my air conditioner leaking water or causing moisture indoors?Most leaks on the Sunshine Coast come from a blocked condensate drain. Humid air makes the indoor unit produce a lot of water, and if the drain clogs, the water backs up and spills. Other causes are a frozen coil, a failed cassette pump, sweating pipes or a poorly levelled unit.
