Frequently Asked Questions 5 Common AC Problems

Every time you turn the Air Conditioner on, the breaker goes

This is irritating!

A weak breaker, a faulty contactor, a grounded compressor, can easily cause it or since the condenser fan was shorted to the ground.

The fan runs, however, the compressor does not

Likely, your compressor is broken in some way!

There might be a burnt wire, a malfunctioning compressor or a malfunctioning beginning capacitor. You may additionally have your compressor shorting out since of the overload security on it. Likely, you will certainly have to change the compressor.

The air conditioner hums, but no fan

You have a humming air conditioner, but you have no air?!

A broken fan, a faulty capacitor or a burned out wire can easily cause this.

The outdoor system is running, however, the fan is not

Any number of things could have gone wrong here, but it might be that you have a grubby filter, the capacitor is broken, a wire burned off, the blower motor is broken, the fan centre is broken, or the evaporator coil is filthy.

You will probably need to pull your air conditioning unit apart in order to identify what is going on.

The air conditioner will not turn on!

Caused by any sort of number of things, this is the downright most common air conditioner problem. There may be an issue with the power supply to the device, a malfunctioning transformer/thermostat/contactor, a contactor wire could have burned off or your dog chewed the wires.

Either way, the issue will primarily have to do with the power supply.

Everything went so smoothly. I had originally contacted few other companies for quotes however none of them called to book a time. Coldflow was the only company who called, was on time with everything and was very professional. From sales to Installation it went great. We love our new system: I would definitely definitely recommend Coldflow.

The team of installers did a fantastic job. We couldn't believe how quick they were in completing the installation of our new air conditioning system. I wouldn't hesitate to recommend Coldflow to friends or family if they require an air conditioner installed.

The Installers, Dave and his two assistants were very organised, planning and executing every part of the installation with precision never wasting a moment. They worked as a professional team always anticipating the next move. Dave's leadership and experience ensured a smooth fit out and a top job. I highly recommend him. They cleaned up too.

I was very impressed with the professionalism and tecnical knowledge of the sales rep. I was sold exactly the right product with the best price and an extened warranty. I am very pleased as I was interstate when the heater broke and my daughter was the only person at home.

Chris Didcock was very friendly and reassured me that the issue would be rectified. However, our heater went back to fault mode after Chris left. As promised, Chris came first thing in the morning and reset the heating unit after being in contact with the manufacturer about the error code.

Chris was exactly on time to do the quote, he was very knowledgeable about what would and would not work and the quote was fast and competitive. The installers were on time, courteous and professional. The installation was neat and they left the house tidy.

Once again Brodie excelled and organised a technician to come straight out to tend to a minor issue. No questions asked just great customer service as always. I highly recommended Brodie and the team at ColdFlow. After using them for the first time a few years ago we would not go anywhere else. A huge 'thank you' to everyone at ColdFlow ??

Darren Storey - Professional, knowledgeable, easy to deal with. Adam scheduled the installation promptly and then it happened a week earlier - great. Installation crew lead by Jason - fast, efficient, timely - considering the wet weather throughout the morning and hopefully all has been done properly.

First of all, the communication was consistent and timely - I always knew where we were up to. On the day, the installation team were fast and efficient and you would not have known work had been done. Similarly, the electrician worked fast and clean. We are really happy with the process and with our new aircon units.

From quote to install went very smoothly. Appreciated the honesty to offer the VEEC rebate as part of quote - other companies gave quotes that did not show this rebate and most likely would pocket the extra themselves. Even the Installation team turned up earlier than expected and did a very professional job. Thanks.

Very likely, your team arrived on time. They worked quickly and efficiently, plus they were very friendly. They left our house as they found it , clean and tidy. Just one thing they left behind a piece of equipment which I'm sure they can use. It is no use to us, so it would be a shame to throw it out. Many Thanks.

Jared came twice because we had a difficult set-up situation in a rear room with a box gutter. The solution worked out well. David and Daniel were professional and friendly installers who installed without fuss or mess. Sparky (Harold) was also efficient and easy to communicate with. My wife and I are very happy with the installation.

The whole installation and mains connection went seamlessly, with only a very small 'mains disconnect' period, which was great as my son is currently WFH and had a very small unavailability time with work. Very happy with the whole process, from quote to installation.

It was explained well about the ducted heating tests. Also the air grill needed replacement but the heating system was old and it may have been difficult to replace. It was fixed so it was not falling down all the time. The office rang to explain another option. However I was happy with the outcome. Thankyou
