A/C Coil Cleaning

Why The Cooling Coil Is The Weak Point

Of all the places in your HVAC system, the air conditioner’s evaporator coil is the one most prone to trouble — and it’s worth understanding why, so the fix makes sense.

Moisture

The coil is wet with condensation all cooling season — that’s simply how air conditioning works, and you can’t keep it dry.

Darkness

Sealed inside the cabinet, the coil is never exposed to the light that would keep biology in check.

Food

Organic dust that slips past the filter settles on the coil and feeds whatever takes hold there.

The result: odour & lost efficiency

Mould and bacteria on the coil or drain pan send musty ‘dirty sock’ smells into your air and drop the system’s airflow and heat transfer — so it works harder for the same result.

A/C Coil Cleaning

Keeping The Coil Clean — And Keeping It That Way

Cleaning removes the existing growth and grime. For homes where the coil keeps re-growing biology, UV coil protection changes the one condition you can — it adds light.

What cleaning does

  • Removes biofilm and grime from the coil area and drain pan.
  • Clears the musty ‘dirty sock’ odour at its source.
  • Restores airflow and heat-transfer efficiency.
  • Included with your furnace-and-A/C cleaning — $405 + GST.

Where UV protection fits

  • Germicidal UV-C keeps the coil and drain pan free of mould and biofilm continuously.
  • Worth considering with central A/C or recurring musty odours.
  • Not a particle filter — it works alongside good filtration, not instead of it.
  • Not essential for every home — we’ll give you honest guidance.

Ask about the Sanuvox R1R

The residential UV unit we most often install is the Sanuvox R1R — a compact, in-duct, Canadian-made system whose R1R-G variant is CARB certified, meaning it uses light, not ozone, to do its work. See the Sanuvox R1R →

Zoned Systems

Cleaning A Zoned Home — Every Zone, Every Run

A zoned system uses dampers and multiple thermostats to condition different areas of your home independently. But the air still moves through the same furnace and duct network — so cleaning only the main trunk leaves most of the system untouched.

Every zone addressed

We clean each zone’s runs, not just the main lines — so the whole setup breathes easy, not just the areas nearest the furnace.

Dampers & branches

Zoned ductwork has more branches and dampers where debris collects. We work through them under negative pressure like the rest of the system.

Clear flat-rate pricing

Each zone is a transparent +$60 and each additional furnace +$150 — every furnace still includes all of its ducting and diffusers. No per-vent charges.

One coordinated visit

Furnace, A/C, every zone and all connected ducting are handled together, so you know exactly what you’ll pay before we start.

Our Process

How We Clean A/C & Zoned Systems

01

We assess the whole system

We map your furnace, A/C and every zone so nothing is missed, then put the duct network under strong negative pressure before we disturb anything.

02

We clean the coil area & return drops

The damp, dark coil enclosure is where biology takes hold. We clear the biofilm and grime that cause musty odours and lost efficiency.

03

We clean every zone and run

Each zone’s runs and dampers are agitated and vacuumed — not just the main trunk — so the whole system breathes easy.

04

We advise on UV protection

If your coil keeps re-growing biology, we’ll give you honest guidance on whether UV coil protection is worth it for your home — no pressure.

Honest Flat-Rate Pricing

No Hidden Fees. No Upsells. Ever.

We price by the system, not by the scare tactic. Every furnace price includes all of its connected ducting and diffusers — there are no per-vent charges and no surprise add-ons.

Single Furnace

No A/C, no zones. Includes all ducting & diffusers.

$345 + GST

Single Furnace + A/C

With air conditioning, no zones. Includes all ducting & diffusers.

$405 + GST

Add-Ons & Extras

  • Each additional furnace (incl. all ducting & diffusers) +$150
  • Each zone system +$60
  • Dryer vent (side of house) $60
  • Roof-exhaust dryer vent Quoted

Every furnace price includes its ducting and diffusers — no per-vent charges, no upsells. Dryer vent cleaning is $60 as an add-on to a furnace or duct cleaning, or $150 as a stand-alone visit ($225 if a bird’s nest must be cleared); roof-exhausting vents are quoted separately. All prices subject to GST.

Frequently Asked Questions

Straight answers about what’s included, how it works, and what it costs.

Your A/C’s evaporator coil sits in a dark enclosure that’s wet with condensation all cooling season and fed by a steady stream of organic dust that slips past the filter — moisture, darkness and food, everything mould and bacteria need. When growth establishes on the coil or in the drain pan, the system can distribute musty ‘dirty sock’ odours into your air, and a coil coated in biofilm and grime loses efficiency: airflow drops, heat transfer suffers, and the system works harder for the same result.
When we clean a furnace-and-A/C system, we address the coil area and return drops along with the furnace and all connected ducting, so the equipment that conditions your air isn’t quietly becoming a source of odour and lost efficiency. Adding A/C to a single-furnace cleaning brings the flat rate to $405 + GST.
A zoned system uses dampers in the ductwork and multiple thermostats to heat or cool different areas of your home independently. Because the air still travels through the same furnace and duct network, every furnace, zone and run needs to be cleaned so your whole setup breathes easy — not just the main trunk. We clean each zone as part of the job.
Each zone system is +$60 on top of your furnace pricing, and each additional furnace is +$150 — every furnace still includes all of its connected ducting and diffusers. We’ll give you a clear flat-rate total up front so you know exactly what you’ll pay before we start.
Cleaning removes the existing growth and grime, which usually clears the odour — but the coil’s conditions (wet, dark, fed by dust) will let biology return over time. For homes with central A/C or recurring musty odours, a UV coil-protection system keeps that critical surface and the drain pan free of mould and biofilm continuously. It’s a biology tool that works alongside filtration, not a replacement for it.
It’s worth considering if you have central A/C, have had recurring musty or ‘dirty sock’ odours, or someone in the home is sensitive to mould. You can reasonably skip it if you have no cooling coil to protect and have never had odour or mould issues — UV sits above the essentials of a good filter, clean ducts and adequate filtration, not before them. We’ll give you the honest guidance for your home.
On the same rhythm as your furnace and ducts — every three to seven years for most homes, sooner if you notice musty odours when the system runs, weak airflow, or you’ve been through a heavy renovation or smoke season.
Yes. Furnace, A/C coil area, every zone and all connected ducting are handled in a single visit, at one flat-rate price with no per-vent charges and no upsells.
