Mick Coy from Coyco with Ben, completed our Meter Box upgrade and installed the electrics for our electric sliding gate.

I would highly recommend them.Posted on Tehlia GrahamTrustindex verifies that the original source of the review is Google.

Absolutely. A unit that is serviced regularly runs much more efficiently because its filters and coils are clean. When your aircon doesn’t have to work as hard to heat or cool your home, it consumes less power, which directly reduces your monthly energy bills. Regular maintenance helps ensure you get the most out of your investment.
Routine maintenance is proactive; it’s a scheduled check-up designed to clean, optimize efficiency, and catch minor issues early, preventing costly breakdowns. A repair, on the other hand, is reactive; it’s the process of fixing a specific fault or component that has already failed and caused the system to stop working properly.
We recommend having your air conditioning system serviced annually. Regular maintenance is key to keeping your unit running at its peak efficiency, preventing minor issues from turning into major repairs, and helping to extend the lifespan of your unit.
