What Our Community Is Saying About RD Air Masters

Raj and his team did an amazing job installing two split systems into our home. We were confident from the consultation he would do a great job as he was very knowledgeable. The quote was very reasonable. The team were efficient and cleaned up after themselves. We are extremely happy with our two new systems.

— Katrina Palaje

Had, Raj from RD Airmasters one and service my ducted Aircon system today. I am happy to say that I’m very satisfied with the job he’s done and the information he has shared regarding why we have been having ongoing issues with our system lagging on start-up. Raj, explained to me what the issue was which no other servicemen have previously offered to do. The Fees are very reasonable compared to most In the industry and therefore would highly recommend!

— Frances Oliveri

Really impressed with the service from Raj - friendly, professional and clearly knows his stuff. He quickly worked out the problem with our air conditioning unit and got it up and working in no time.

Always nice to support a family-run business, especially when they deliver great service like this. Would happily recommend RD Airmasters to anyone.

What's Actually Wrong With Your Ducted Heating?

Every heating fault has a cause, and most fall into a handful of categories. Here's a quick way to narrow down what's likely going on before a technician even arrives:

01

No Airflow or Weak Airflow

If air is barely coming through the vents, the fan motor or ductwork could be the culprit. This often gets worse gradually before it fails completely.

02

Pilot Light or Ignition Faults

A heater that won't fire up — or shuts off soon after — usually points to an ignition or pilot light issue. This needs prompt attention for safety reasons.

03

Thermostat Not Responding

If your set temperature and actual room temperature don't match, the thermostat itself may be miscalibrated or wired incorrectly, not the heater unit.

04

Unusual Noises During Operation

Rattling, banging, or grinding sounds usually mean a mechanical part — fan, motor, or bearing — is wearing down and needs inspection before it fails outright.

Signs Your Gas Heater Needs to Be Repaired

If your gas heater isn't performing like it used to, or has stopped working altogether, it's likely time for urgent repairs. This is often the case when a system has been overworked or hasn't been serviced recently. Some key warning signs include:

Poor heating performance

If your home is slow to heat, or some rooms cool down too quickly, there may be a fault with the unit — commonly a clogged filter, damaged heating element, or thermostat issue.


Rising energy bills

An unexplained increase in your gas bill can be a sign something is wrong with your heater. Getting it checked early can save you money down the track.


Strange noises from your heater

This could point to a problem with the fan, motor, or compressor. These issues should be repaired before the unit is used again.


Gas heater won't turn on at all

This requires a licensed technician to diagnose. Common causes include a blown fuse, tripped circuit breaker, or wiring fault.
