Frequently asked questions

Clear, honest answers for builders, strata, and property owners.

HVAC & AIR CONDITIONING SPECIFICATION

HVAC Air Conditioning & Ventilation (10 Key Answers)

Everything you need to know about ducted systems, split units, acoustic compliance, and home airflow optimization.

Swipe left / right
01 SYSTEM SELECTION

Should I install a ducted air conditioning system or multi-head split systems?

Ducted: Whole-home seamless climate control concealed in roof space with smart multi-zone controls.

Split Systems: Ideal for targeted individual rooms or homes without roof cavity clearance.

02 POWER & SWITCHBOARD

Will my electrical switchboard need an upgrade for new air conditioning?

Large ducted systems (12kW+) require a dedicated circuit breaker and often 3-phase power, which we evaluate during site inspection.

03 STRATA & OUTDOOR UNITS

How do you handle strata approvals for condenser units on balconies?

We supply noise level specifications, vibration isolation rubber mounts, and mounting plans to satisfy strata committee guidelines.

04 NOISE & ACOUSTICS

Will the outdoor condenser unit disturb my neighbours at night?

We install inverter-driven, low-dB condenser units positioned away from boundary bedrooms, meeting council acoustic noise thresholds.

05 SMART ZONING

Can I control temperatures in individual rooms separately?

Yes. Smart zone controllers allow you to turn airflow on/off in individual bedrooms or living areas to save power consumption.

06 DUCTING QUALITY

What type of flexible ducting is used to prevent energy loss?

We install high-grade R1.5 insulated flexible ducting with airtight core lining to ensure maximum energy efficiency and zero thermal loss.

07 AIR QUALITY & FILTERS

How do HVAC systems handle dust, mold, and humidity control?

We integrate washable HEPA filters, indoor moisture condensation drains, and fresh-air intake units to keep indoor air clean and allergen-free.

08 INSTALLATION TIMELINE

How many days does a full ducted HVAC installation take?

Standard residential ducted installations take 1 to 2 days, including electrical hookup, ceiling vent fitting, and system commissioning.

09 WARRANTY & SERVICE

What warranty covers my new HVAC system?

Systems carry a 5-year full manufacturer warranty on compressors and parts, supported by our licensed installer workmanship guarantee.
