Duct Cleaning
Once a year keeps a duct system in the condition it was installed in. Everything a house sheds ends up in the trunk lines first, and a running system moves that same air through every room several times a day.
What the ducts have to do with the coil
Dust does not stay in the ducts. The same load that coats a trunk line coats the coil it feeds, and a coil working through a film of dust is a coil giving up capacity it was built to have. That is why a job that starts as a duct clean sometimes turns into a conversation about why a system feels weaker than it used to. Joints get sealed with mastic rather than taped over, because tape dries out and a taped joint is a leak with a delay on it.
Why airflow is the real measure
Most of what gets called a weak air conditioner is a system moving less air than it was built to move. Restriction anywhere in the duct run, a return that was never sized right, a filter overdue for a change, shows up the same way at the thermostat: long run times and rooms that never quite catch up. Clearing and sealing the ducts is often the cheaper fix to try before anything gets replaced.

Before and after a cleaning visit
A sealed run is capacity nobody paid extra for
A plenum that leaks around its seams is pulling attic air into the supply side or losing conditioned air into the attic, depending on which side of the fan the leak sits on. Either way the house is paying to condition air it never gets to use. Sealing the run and clearing what has built up inside it are the same visit, because checking one without the other only tells half the story.
It pairs naturally with an attic insulation check, since both live in the same space and both affect the same bill, and it is one of the things a maintenance visit looks at as a matter of course.

Cleaned once, sealed so it stays that way
A duct system that gets cleaned but not sealed is back to the same state within a season, because the same gaps that let dust in keep letting it in. That is the reason mastic gets used on the joints instead of tape: mastic bonds to the metal and stays flexible, tape has an adhesive life and this attic runs through a Cypress summer twice a year.

Cypress and northwest Houston
This is what the ductwork behind the walls actually looks like
Run exposed here because the room is a converted barn, but the run, the seams and the seal are the same job whether anyone will ever see them or not. If it has been more than a year, or the airflow feels weaker than it used to, that is worth a look before anything gets replaced. See the full list under services.
