Troubleshooting Tips Before you Call COYCO

Easy Steps to Rule Out Common Issues

Sometimes, common air conditioning problems can be solved with a quick check at home. Before booking a repair, try these steps:

Ensure the unit is receiving power — check your switchboard and circuit breakers
Make sure the remote or thermostat batteries aren’t flat
Clean or replace air filters if they look dusty or blocked
Check that vents are open and not obstructed by furniture
Inspect the outdoor unit for leaves, dirt, or blockages (especially in a rural block in Hopelands or Karnup)
Confirm that your settings are correct (zones on or off, cooling vs heating, temperature level)

If you’ve tried these and your system still isn’t working, COYCO’s team is ready to step in and get your air conditioner back on track. Don’t wait for the weather to turn before booking your air conditioning repair.

 Trustindex verifies that the original source of the review is Google. I requested getting a charger that can use solar only and I ended up getting one that didn't (Technically it can if you have the same brand inverter and battery but I don't). I then contacted them multiple times and didn't hear back from them around this. They then followed up with me and Kirsti gave me information on using the EV charger. A good price and they did the work well. Just remember to check that your EV charger does what you want it to do before buying.

 Trustindex verifies that the original source of the review is Google. Had a great experience with Coyco when helping my parents sort out their air conditioning. The service was excellent, pricing was really reasonable, and the whole process was smooth from start to finish. Mick, the owner, was especially helpful and genuinely cared about getting the right outcome. We went with the Panasonic brand which has been great to combat the heat we've had here over the Christmas break. Would happily recommend Coyco.

 Trustindex verifies that the original source of the review is Google. Mick Coy from Coyco with Ben, completed our Meter Box upgrade and installed the electrics for our electric sliding gate. They were most obliging, solved difficult problems and worked with enthusiasm and precision. Mick was fair and most reliable. I would highly recommend them.

Everything was completed to a high standard and with great attention to detail. Mick was really friendly and easy to deal with, which made the whole process easy and stress free. We highly recommend Coyco!

Frequently Asked Questions

Your Air Conditioning Repair Questions, Answered.

Why is my air conditioner not cooling (or heating) properly?

There are many common reasons for poor performance, including a blocked filter, low refrigerant level, or a fault with the thermostat or compressor. Don’t worry—our highly trained technicians can quickly diagnose the problem and provide a reliable solution. To keep your system running optimally and avoid these issues, schedule routine air conditioning maintenance.

Call and book a call-out now. (08) 9525 0562 or 0404 987 072

Should I repair my old unit or replace it?

The decision depends on the unit’s age, the severity of the repair, and the cost. If your unit is more than 10-15 years old or the repair cost exceeds 50% of the replacement cost, an upgrade is often the better long-term choice.

We will always provide an honest assessment, and if replacement is necessary, you can explore our premium options for Split System Air Conditioning or Ducted Air Conditioning .
