Coburg mixes solid interwar brick homes with new Pentridge-precinct townhouses, and their splits carry both cooling and winter heating. FreshDuct cleans coils, fans and condensers, with photo proof.
Reverse-cycle split heating and cooling all year? That run time builds grime — a clean clears it.
Coburg is an established inner-north suburb built around Sydney Road and the old Pentridge site, with a settled mix of sturdy interwar and post-war brick homes, Victorian cottages, and a growing layer of townhouses and apartments in the redeveloped Pentridge precinct. Split systems are the common climate control, and in many Coburg homes a single reverse-cycle unit does double duty — cooling in summer and heating through the cold inner-north winter.
That all-year use is the local factor. A split that heats as well as cools clocks up far more run hours than a cooling-only unit, and every one of those hours draws air and moisture across the indoor coil and barrel fan. Grime and black mould build up steadily inside the head, cutting both the heating and cooling and bringing the musty smell owners notice when the unit kicks on. The solid brick homes hold heat and cold well, but a clogged split still struggles to keep up.
FreshDuct cleans Coburg splits for this year-round duty. We deep-clean and sanitise the indoor coil and fan to clear the grime and mould, wash the outdoor condenser, clear the filter and drain, and finish with before and after photos.
The things we look at first on a Coburg split system — based on the local homes and conditions.
Many Coburg splits heat in winter and cool in summer, so they run far more hours than a cooling-only unit. That heavy use builds grime and mould inside the head, so a yearly deep clean keeps both seasons working and the air healthy.
The extra run time draws moisture across the coil and drum, growing mould that brings the musty start-up smell. We deep-clean and sanitise the fan and coil to clear it at the source rather than mask it.
Steady grime on the coil and fan cuts both the heating and cooling a Coburg split can deliver. Clearing it restores the airflow and the output the unit had, so it reaches temperature without labouring.

A Coburg reverse-cycle split earns its keep across both seasons, heating the home through a cold inner-north winter and cooling it through summer. All those extra run hours mean grime and mould build up inside the head faster than in a unit that only runs a few weeks a year.
We deep-clean and sanitise the indoor coil and fan to clear the build-up, and wash the outdoor condenser so it sheds heat efficiently. For a home that leans on one unit all year, a regular clean means healthier air and lower running costs in every season.
FreshDuct cleans split systems across Coburg and the inner north 7 days a week. We regularly work neighbouring Brunswick, Preston, Thornbury and Campbellfield, so Coburg and its borders are part of our everyday run.

Because it runs so many more hours than a cooling-only unit, moisture and grime build up on the coil and barrel fan and grow black mould, which causes the musty smell. Since you also heat the home with it, that air is recirculated. A deep clean and sanitise clears the mould at its source and freshens the air.
Often, yes. A split that heats in winter as well as cooling in summer clocks up far more run time, so grime and mould build faster than in a cooling-only unit. A yearly deep clean is a sensible baseline, and heavy winter heating use can make it worth cleaning more often.
