Most homes benefit from a cleaning every 3–5 years, though pets, allergies, renovations, or a home that's never been cleaned before can mean sooner.

Visible dust around your vents, musty odours when the system runs, or a home that hasn't been professionally cleaned in years are all good signs it's time.

The full system: supply ducts, return ducts, registers and grilles, the main trunk lines, and the furnace/blower compartment where applicable.

Most residential jobs take 1–2 hours depending on the size of the home and number of vents. We'll give you a time estimate before starting.

Truck-mounted systems generate far more suction than a portable unit plugged into a wall outlet, and debris gets pulled straight into the truck instead of a bag or filter sitting inside your home.

Very low-priced offers usually don't cover a full system cleaning, use weaker equipment, or add fees once the crew arrives. Always confirm exactly what's included before booking.

We can't promise specific health outcomes — everyone's situation is different. What we can say is that a clean duct system means less accumulated debris getting circulated through your home. Learn more about our residential duct cleaning.

Most homes benefit from a cleaning once a year, though heavy laundry use or long vent runs may need it more often.

Clothes taking longer than one cycle to dry, a dryer that feels very hot to the touch, a burning smell while it runs, or lint building up around the outside vent flap are all common signs.

Yes — blocked dryer vents are one of the leading causes of home dryer fires according to fire-safety authorities.

Yes. When airflow is restricted, your dryer has to run longer to dry each load, which uses more energy and puts extra wear on the machine.

Most dryer vent cleanings take 30 to 60 minutes depending on the length and layout of the vent line. We disconnect the dryer briefly, then reconnect and test it before we leave. Learn more about our dryer vent cleaning.

Most fire-safety authorities recommend an annual inspection and cleaning for chimneys used regularly through the winter.

Yes — creosote is highly flammable and a leading cause of residential chimney fires when left to build up.

Yes, every cleaning includes a visual inspection of the flue, damper, and firebox for damage or blockages.

No. Our HEPA-filtered vacuum equipment contains soot and debris instead of releasing it into your home.

Most residential chimney cleanings take about 45 minutes to an hour, depending on the level of buildup. Learn more about our chimney cleaning.

Most manufacturers recommend servicing your furnace and air conditioner once a year, ideally before their peak season.

A full inspection, filter and airflow check, component tune-up, and performance testing, with a walkthrough of anything that needs attention. Learn more about our HVAC service and repair.

If your furnace is 15+ years old or needs frequent, costly repairs, replacement is usually the better long-term value. We'll give you an honest recommendation either way.

Most furnace replacements are completed in a single day. We'll confirm the timeline for your home when we quote the job. Learn more about our furnace replacement.

Yes. In most homes, central air connects to your existing furnace and uses the same ductwork to deliver cool air to every room. Learn more about our AC installation.

If both are getting older, replacing them together can make sense since they share the same blower and ductwork. We'll tell you honestly whether it's worth it.

Visibly thin, patchy, or compressed insulation, along with high energy bills or ice dams, are common signs it's time for an upgrade.

Spray foam is usually worth it where air sealing and moisture matter most: rim joists, basement walls, vaulted ceilings, and rooms over garages. For open attic floors, blown-in insulation is often the better value. We'll tell you which fits your home when we quote your project.

Sealing air leaks and improving insulation reduces the load on your heating and cooling system, which typically lowers energy costs. How much depends on how leaky and under-insulated the area was to begin with.

Yes. Once fully cured, spray foam is stable. The space is ventilated during application and curing, and you stay out of the area until it's safe to return. Learn more about our spray foam insulation.

It depends on the space. In attics we can often insulate over existing insulation, but damaged, wet, or contaminated insulation usually needs to come out first. We'll tell you what's needed when we quote your project.

Most residential attics can be insulated in a single day, and most spray foam projects take a few hours to a full day depending on the size of the area. Learn more about our attic insulation.

We plan every project around your operating hours, staff, and customers — including after-hours or phased work for larger buildings.

Timing depends on the size of the building and ductwork, from a few hours for a small office to multiple days for larger facilities.

Where accessible, yes — rooftop unit and air handler cleaning is part of a full-system service.

Most commercial systems benefit from cleaning every few years, though usage, tenant turnover, and renovations can change that timeline.

Yes, we work with property managers overseeing multiple buildings or units and can coordinate scheduling across a portfolio. Learn more about our commercial duct cleaning.

Ottawa and most surrounding communities, including Kanata, Barrhaven, Orleans, Kingston, and more. See our full service area list — if your city isn’t listed, reach out anyway.

We recommend it so we can walk you through what we find, but it's not strictly required as long as we have access to the home.

No. Our equipment is built to contain dust and debris rather than release it into your home, and our techs lay down floor protection and keep a tidy work area near vents and entry points.

Yes, on every cleaning job — so you can see exactly what was done, not just take our word for it.

We need a clear path to your furnace and vents, plus the nearest driveway or curb access for our truck-mounted equipment.

Yes, we service condos and multi-unit buildings in addition to single-family homes.

Yes. Older ductwork is one of the most common reasons homeowners call us, and we're experienced working with older systems.
