FAQ
Get answers to common questions about Relevant Air's experienced heating and cooling installation, repairs, and maintenance services with our FAQ.
Can I install a split system myself?
Yes, we can supply you with a split system but for safe, reliable operation, we recommend professional installation by our licensed technicians. We have the specialist skills and knowledge for quick, quality split system placement.
How do I decide between ducted vs split system air conditioners?
When advising customers, we examine factors like the size of the area needing temperature control, efficiency goals, budget, and visual preferences. Ducted suits whole homes, while splits efficiently cool individual spaces at a lower cost. Our team can assess your home and recommend the best system.
What are the disadvantages of split AC?
Our skilled technicians properly site and install split systems to prevent issues like reduced efficiency or higher energy use. We’ll ensure your unit has adequate wall space in your home or apartment for optimal comfortable performance.
What is a split system air conditioning?
A compact indoor unit connected by pipes to an external condenser provides efficient, zoned cooling without ductwork. It’s an affordable, non-invasive climate control solution.
What’s the cost difference between split and ducted air conditioners?
Split systems tend to be more budget-friendly, with lower install and running costs than ducted. While ducted centralises cooling for the whole home, splits provide an affordable way to cool individual rooms.
Are portable air conditioners any good?
Portable air conditioners are not ideal, but they are an alternative. Typically, they take up a lot of space, are louder to run and not energy efficient.
