Is it urgent?

Can wait

Rarely urgent, and often not needed at all. Sanitizing is worth paying for where cleaning found actual microbial growth and the conditions that caused it are being fixed. Applied to a clean, dry system it accomplishes very little, and applied without fixing the moisture it accomplishes nothing for long.

Two things override everything on this page. If anyone has symptoms of carbon monoxide exposure — headache, nausea or dizziness that improves outdoors — leave the building and call the gas utility or the fire service, not a duct company. And if you can smell burning while the dryer is running, unplug it and leave it.

Signs to look for

Cleaning that turned up visible growth on duct surfaces or on the coil
A persistent musty smell that survived a proper cleaning
Water damage or a flood that reached the ductwork
A system that has been off and damp for a long period, such as an empty property
Someone in the house with asthma or a diagnosed mold allergy, where the calculation is different

How the work is done

Cleaning first. An antimicrobial applied over debris treats the debris, not the duct
Identifying and fixing the moisture source, because growth without moisture does not return and growth with it always does
Applying only EPA-registered products labeled for use in HVAC systems, at the labeled rate
Leaving the system off for the labeled dwell time rather than restarting it immediately

In Connecticut specifically

In Connecticut the ductwork is generally in basements, often unfinished, with runs through a fieldstone or block foundation space that is cooler and damper than the house above, which is most of why this job looks the way it does here. Connecticut is a heating state with old housing, and a large share of it burned oil for decades. Oil-fired systems leave a finer, oilier soot than gas does, and on a house that has been converted the old residue is still in the ductwork after the boiler has gone. A lot of Connecticut housing also has no ducts at all — baseboard hot water and steam are common — so the first question on a Connecticut call is genuinely whether there is a duct system to clean.

Before the technician arrives

Four things worth doing — and the first one is usually the thing people get wrong.

Ask what product is being used and ask to see that it is EPA-registered for HVAC use. "Fogging" with an unlabeled product is a real thing in this trade and it is not the same job.
Plan to be out of the house for the dwell time, and longer if anyone in the household is sensitive.
Deal with the water first if there is water. Sanitizing a damp duct is money spent on a problem that is still there.
Keep the cleaning report — it is what establishes the treatment was warranted.

How it works

Three steps, and you decide at the end of them.

1
You call and describe the problem

Tell us what you have noticed and where — the room, the smell, the noise, how long it has been going on. Give us your ZIP code and we will match you to a licensed company covering your area. There is no form to fill in.
2
A local company takes it from there

They discuss the problem with you directly, arrange a time to inspect, and agree the work and the price with you before anything starts. That conversation is between you and them.
3
You decide whether to go ahead

You are under no obligation. If the quote or the approach is not what you wanted, you are free to say no and call someone else.

Duct Sanitizing — FAQs

Do I actually need Duct Sanitizing done?

Rarely urgent, and often not needed at all. Sanitizing is worth paying for where cleaning found actual microbial growth and the conditions that caused it are being fixed. Applied to a clean, dry system it accomplishes very little, and applied without fixing the moisture it accomplishes nothing for long.

What does Duct Sanitizing involve?

An EPA-registered antimicrobial applied to duct surfaces after cleaning, where there has been confirmed microbial growth. It is a treatment for a diagnosed problem, not a deodorizer.

What makes this different in Connecticut?

In Connecticut the ductwork is generally in basements, often unfinished, with runs through a fieldstone or block foundation space that is cooler and damper than the house above, which is most of why this job looks the way it does here. Connecticut is a heating state with old housing, and a large share of it burned oil for decades. Oil-fired systems leave a finer, oilier soot than gas does, and on a house that has been converted the old residue is still in the ductwork after the boiler has gone. A lot of Connecticut housing also has no ducts at all — baseboard hot water and steam are common — so the first question on a Connecticut call is genuinely whether there is a duct system to clean.

Are the companies licensed and insured?

Yes. We only pass calls to licensed, insured operators working in Connecticut, and you are welcome to ask to see a license number on arrival.

What does Duct Sanitizing cost?

It depends on the property, the size of the system and what the inspection finds, so we do not publish a price — a figure quoted on a web page is not one the attending company has agreed to. You get a price before any work starts.
