 From Homes to Businesses

Stephen Jacobs

“We recently had a pool heater, pool blanket, and high-quality roller installed by **Relevant Air and Water** from Penrith, and the entire process was absolutely seamless and stress-free! From start to finish, Shane and the team were nothing short of professional.

Shane’s clear, concise instructions made the project details simple to understand, and his attention to precision reassured us that we were in the best hands. He explained everything thoroughly, leaving no questions unanswered.

A special shout-out to Hayley and the team for their outstanding project follow-through. Their professionalism and focus on delivering a quality outcome were evident throughout the entire process. It’s clear they have a deep understanding of their core business, and they deliver with trust and care.

We’re thrilled with the results and highly recommend **Relevant Air and Water** to anyone looking for local professionals who excel in their craft! Thank you again for making this such a smooth and easy process”

Joseph Pirrello

“I was really happy with the service Shane provided. He repaired a Rheem pool heater that had an outgoing water temp fault. He undertook some maintenance items on the unit at the same time. His rates were competitive and undertook the work quickly. He certainly knew his stuff and will call him back in the future for routine maintenance.”

“Haley from the team reached out about a sale enquiry, and was exceptional helpful!! She really cares about the customers outcome and not just making a sale!”

“I highly recommend this company! We used them to fix our air conditioner. From the initial phone call with their friendly team to the tech they sent out who was very knowledgeable and professional. Would not hesitate to use them again.”

“Shane and Will were efficient – they acted like they were working on the clock, which they were as I was paying by the hour, so that was good.

They still have stock of parts for my Accent Airconditioner (Accent shut down their business over 10 years ago) and quickly and efficiently repaired it unlike other companies who said my only option was to install a new unit, which would have been much much more expensive.”

Brien Coram

“From my initial contact to the on-site repairs, my experience with the Relevant Air team has been an absolute pleasure. The team are pleasant, efficient, have deep knowledge of my (Accent Air) system, and offer proactive, realistic, tangible advice on service options. I cannot speak highly enough of Shane, Hayley and team, and look forward to a lasting relationship with Relevant Air.”

The new ones performing so much better than the old ones. Nobody wants to sweat it out more than necessary – Relevant Air & Water fixed that!”

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.
