Frequently asked questions
Can air conditioning heat my home?
Yes. Modern units are heat pumps, so the same system that cools your home in summer can heat it efficiently in winter.
Is it expensive to run?
Modern systems are efficient and often cheaper to run than expected, especially for heating. Your running cost depends on how much you use it and how well insulated your home is.
Is it noisy?
No. Today’s systems run very quietly — the indoor unit is barely audible and the outdoor unit is engineered to keep noise low.
Will it work in every room?
Systems can cover a single room or several rooms. During your free assessment we will recommend the right type and number of units for your home.
How long does installation take?
Most installations are completed within one to two days, depending on the number of units and your home layout.
Does it need much maintenance?
Very little. An occasional filter clean and a periodic service is usually all that is needed, and we can advise on the best routine for your system.
Is it greener than my old heating?
Typically, yes. Because a heat pump moves heat rather than burning fuel, heating with air conditioning often produces fewer carbon emissions than an older fossil-fuel system.
Can I control each room separately?
Yes. Multi-split and ducted systems let you set different temperatures in different rooms, so everyone stays comfortable.
