Window Air Conditioners
Some window and through-wall air conditioners offer both heating and cooling functions, making them a versatile option for small spaces.
In heating mode, they use an electric heater or a heat-pump mechanism to warm the room.
These units combine all major components—compressor, coils, fan, and heating element—in a self-contained package that fits within a window or wall opening.
At Paterson Air Conditioning, we supply and install these compact units.
Our team ensures the window frame or wall sleeve is suitably prepared and the unit is levelled, sealed, and connected to a dedicated power circuit.
While installation is straightforward, safe operation and longevity depend on proper maintenance through periodic servicing.
This includes checking the mounting seal and brackets, cleaning or replacing filters, vacuuming coils, clearing drain channels, and testing the heating elements and electrical connections.
During a service we also inspect insulation around the sleeve or window frame and lubricate moving parts to reduce noise and wear.
If your window unit fails to produce heat, blows cold air, trips the breaker, or shows signs of excessive condensation, our technicians can diagnose the issue, explain the underlying fault, and advise whether repair or replacement is the best course.
We provide honest, upfront quotes, flexible payment options, and back our workmanship with a lifetime labour guarantee.
For a compact heating and cooling solution in a single room, talk to us about window and wall units and learn how to keep them running safely for years to come.
