Box Hill blends established brick-veneer homes with new apartment towers, and ducted gas heating runs through much of the older housing. FreshDuct services it carefully — carbon monoxide test, burner clean and a full function check.
Brick-veneer home with an ageing heater? A service and CO test keeps it safe and efficient.
Box Hill is a busy eastern hub where established brick-veneer family homes surround a growing cluster of apartment towers and a major transport interchange. Ducted gas heating runs through much of the older housing stock, and a good deal of it has been keeping homes warm for decades.
An ageing ducted heater in a Box Hill home shows its years in familiar ways — a dust-loaded filter, worn ignition parts, a heat exchanger due for inspection. We clean and tune the burner, replace the small worn parts, inspect the exchanger and run a carbon monoxide test so an older heater keeps running efficiently and safely.
The things we check first on a Box Hill ducted gas heater — based on the local homes, systems and conditions.
Established Box Hill homes often keep the original ducted heater. We inspect the heat exchanger for cracks and corrosion and CO-test the unit every service.
Years of dust choke the return-air filter of an older Box Hill system. We clean the burner and replace the filter so the heater breathes and warms the home efficiently.
Whatever the age of the unit, every Box Hill service finishes with a heat-exchanger inspection and a negative-pressure carbon monoxide spillage test.

A Box Hill ducted heater that has warmed a brick-veneer home for decades is usually worth keeping if it is serviced properly. We clean the burner, replace worn parts, inspect the heat exchanger and run a carbon monoxide test.
The usual Box Hill issue is a heater grown slow or dusty over the years. We clear the filter and airflow, tune the burner and give an honest view on whether the unit will see out a few more winters or is due for replacement.
FreshDuct services ducted gas heaters across Box Hill, Box Hill North and Box Hill South 7 days a week, and we work nearby in Balwyn, Doncaster, Glen Waverley and Ringwood, so a Box Hill job fits into our run.
From the family homes around the station precinct to the quieter streets towards Surrey Hills, we can usually offer a prompt autumn service and prioritise a heater that has stopped working.
A thorough, documented annual service — every component checked and a carbon monoxide test done before the cold sets in.
We check the whole ducted gas heater — burner, heat exchanger, gas valve, thermocouple, ignition and wiring.
A negative-pressure CO spillage test to make sure the heat exchanger is sound and nothing is venting into your home.
Burner, injectors and ignition cleaned and adjusted so the heater lights reliably and burns cleanly.
Return-air filter and supply vents checked and cleared so warm air flows freely to every room.
Thermostat, sensors and controls tested so the heater cycles correctly and holds the temperature you set.
A clear service report with photos and honest advice on whether to service or replace.

Yes. Many Box Hill homes keep the original ducted gas heater for decades. We clean the burner, replace worn parts and the filter, inspect the heat exchanger and run a carbon monoxide test, and advise honestly on the unit’s remaining life.
Usually a build-up of dust on the filter and burner, plus ignition parts past their best. We clean the burner, replace the filter and any worn parts, and clear the airflow so the heater warms the home quickly and evenly again.
Yes. FreshDuct services, tunes and carbon-monoxide tests ducted gas heaters across Box Hill and the surrounding eastern suburbs, 7 days a week. Call 04 3191 8137 or request a free quote.
A standard annual service and carbon monoxide test is a fixed, affordable price; the cost only changes if the heater needs a part such as a thermocouple, igniter, filter or fan component — and we quote those clearly before we fit anything. Call 04 3191 8137 for pricing.
Every two years at a minimum, and ideally once a year before winter. An annual service in autumn means the burner, heat exchanger and controls are checked and a carbon monoxide test is done before you rely on the heater through the cold months.
Yes. Every ducted gas heater service we do includes a carbon monoxide safety check — we test for CO spillage and inspect the heat exchanger for cracks, because a faulty exchanger can leak carbon monoxide into the home. It is the single most important reason to service a gas heater.
Annual service and tune, carbon monoxide safety test, burner & heat-exchanger check, filter and airflow — a clean, documented service with photo proof. Available 7 days.
