Aircon & heat pump tools you can use right now.
Three free calculators and reference tools we use ourselves on quote day. Work out what size aircon fits your room, what it’ll cost to run, or what that flashing fault code on your existing unit actually means.
Aircon Sizing Calculator
What size aircon does this room need?
Get the right kW rating for your room in seconds. Enter the room dimensions, ceiling height, orientation and insulation — the calculator handles the industry-standard heat-load formula so you don't quote the wrong size.
- Australian residential heat-load formula
- Adjusts for ceiling height, orientation, insulation, glazing, occupants
- Recommends a cooling capacity range (kW) + closest standard model size
VEU Rebate Estimator
How much rebate can I claim?
Enter your postcode, current system and planned upgrade — get the estimated Victorian Energy Upgrades rebate range and your net out-of-pocket install cost. Covers hot water and space heating/cooling upgrades.
- Every VEU upgrade path (gas / electric → heat pump, gas ducted → RC)
- Household size + solar adjustments for hot water
- Rebate range + net install cost after rebate
Gas vs Reverse-Cycle Heating
Which is cheaper to run this winter?
Compare the annual winter running cost of a gas ducted heater against a reverse-cycle (heat pump) system for your home. Enter heat load, hours, star rating, COP and tariffs — get the payback if you swap.
- 3 to 6-star gas efficiency + inverter reverse-cycle COP
- Annual saving + payback with VEU rebate applied
- 10-year net saving projection
System Type Comparison
Split vs multi-head vs ducted vs gas vs evap.
Side-by-side comparison of the five main home climate-control options — install cost, running cost, zone control, lifespan, best-for scenarios and which brands we install for each. Pick 2-5 systems to compare.
- 5 system types · toggle any 2-5 to compare
- Real Melbourne install-cost + running-cost ranges
- Pros, cons, brands and rule-of-thumb picks
Hot Water Savings Calculator
How much will a heat pump save me?
Compare your current gas or electric hot water annual cost against a modern heat pump. Applies the Victorian VEU rebate to the install cost and projects the payback period over 10 years — the fastest way to see if the upgrade actually pays for itself.
- Handles gas storage, gas continuous, electric peak, off-peak and solar-boost
- VEU rebate applied to net install cost
- Payback in years + 10-year total savings
Running Cost Calculator
What will this cost me to run?
Estimate the electricity cost of running an aircon or heat pump per day, week and year. Uses your unit's kW input (or capacity + COP), your usage hours and your electricity price to project the real running cost.
- Works for split, multi-head, ducted and heat pump hot water
- COP + capacity → kW input conversion built in
- Shows cost per day, per week and per year at your electricity rate
Aircon Fault Code Lookup
What does this error code on my aircon mean?
