When duct cleaning makes sense
Duct cleaning is not something every home needs every year. It is worth doing when:
- You see dust blowing out of the vents or visible buildup on vent covers and return grilles
- The home was recently built or remodeled and construction dust got into the system
- You have moved into a home and do not know when the ducts were last cleaned
- There are signs of pests in the ductwork
- Family members with allergies notice symptoms when the system runs
- Rooms that used to get good airflow now feel weak
What we do
We inspect the ducts first so you can see what is actually in them. Cleaning uses negative air pressure to pull debris out of the system while brushes and air whips loosen buildup from the duct walls. We clean the supply and return runs, the registers and grilles, and check the blower and indoor coil, since cleaning the ducts while leaving a dirty blower just recontaminates them.
During cleaning we often find other problems: disconnected runs, crushed flex duct, or gaps where attic air is being pulled into the return. Those are worth fixing, and we will show you what we find. See duct repair and installation.
Keeping ducts clean
Filters are the first line of defense. In Las Vegas, where dust is constant, check the filter monthly in summer and replace it when it is dirty. A higher-rated filter traps more dust but can restrict airflow on some systems, so ask us which filter your system can handle. Sealing leaks in the return ducts also matters, because a leaking return in the attic pulls dusty attic air straight into the system.
Duct cleaning pairs well with an AC tune-up, since the tune-up cleans the coil and blower. If airflow is still weak after cleaning, the problem may be the system itself; see AC repair.
Service area
We clean ducts across Las Vegas, Henderson, North Las Vegas, Summerlin, Paradise and Boulder City. Homes without ducts in part of the house may be better served by a mini-split.
What we find in Las Vegas ducts
Fine desert dust
The most common find. It settles in returns and low spots and blows back out when the system starts.
Construction debris
Drywall dust, sawdust and insulation from building or remodeling, which can clog filters and coils quickly.
Pest evidence
Occasionally nests or droppings where a duct has come loose in the attic. We clean it out and point out where the opening is.
What duct cleaning does not fix
Cleaning removes buildup, but it does not seal leaks, reconnect loose runs or fix a system that is too small for the house. If the ducts are leaking, cleaning is a good time to find the leaks, but repair is what stops them.
Preparing for a duct cleaning
There is not much you need to do. Clear a path to the air handler and to each vent and return, and move anything stored directly under ceiling registers. Plan to be home for the visit, since we need access to the whole house and the attic. Pets are happiest in a closed room or out of the house for the few hours the equipment is running. When we finish, replace the filter with a fresh one, or let us do it, so the clean ducts stay clean.
Questions we hear a lot
How often should ducts be cleaned?
There is no fixed schedule. Clean them when there is visible buildup, after construction, or if you do not know their history. A good filter routine stretches the time between cleanings.
Will duct cleaning lower my energy bill?
Cleaning alone mainly helps airflow and dust. Sealing leaks in the ducts is what saves real energy; see duct repair.
How long does it take?
Most homes take a few hours, depending on the number of vents and the condition of the ducts.
Is duct cleaning safe for people with allergies?
Yes, and it often helps. The negative-pressure equipment keeps loosened dust moving out of the house rather than into the living space. People with allergies or asthma may want to be out of the house during the cleaning and replace the filter right afterward. If allergy symptoms continue, sealing return-duct leaks that pull in attic dust is often the missing piece.
