What to Expect

  1. 1

    Tell Us What You See

    Take pictures of the registers, the filter and any visible plenum debris. Note when odors appear and which rooms feel different.

  2. 2

    We Look at the Whole System

    We start with the system in front of us: supply and return runs, registers, the plenum and accessible coil and blower areas. You get a scope that matches it.

  3. 3

    Protect and Set Up

    The crew protects floors and furnishings and seals access points. Clear access to registers and the air handler helps, and pets should be kept away from open doors and work zones.

  4. 4

    Clean Under Negative Pressure

    Negative pressure keeps loosened material moving toward collection equipment while brushes and air tools release dust from interior surfaces. Registers are removed and cleaned.

  5. 5

    Show You What We Found

    We show you what was in the returns and plenum, with before-and-after photos. If a duct is torn or collapsed, or we find moisture, we tell you, because cleaning will not repair it.

Air Duct Cleaning Questions

How often should air ducts be cleaned?

In San Antonio we recommend having ducts cleaned every two years. Construction dust and our dry climate load a system faster than in most cities. Sooner with pets, remodeling dust or a recent water event. A clean, tight system with good filtration may go longer, and we do not use a calendar alone to recommend service.

What does a whole-system cleaning include?

Supply and return runs, trunk lines, registers and the plenum, with coil and blower detailing. A vacuum hose held at each register is not a whole-system cleaning. Our team is certified in Mechanical Systems Hygiene through ASCR and RIA.

How do I know if my ducts need cleaning?

Look for thick dust or dark streaks at the supply registers soon after wiping them, a filter that loads up in a few weeks, weak airflow at certain registers, a musty smell when the system first kicks on, or visible debris inside the plenum. Each sign has other possible causes, so we inspect before we recommend.

Why not a low-price whole-house special?

A very low whole-house price does not cover the labor, equipment and time required to clean an entire HVAC system correctly. It is usually an opening price. Ask whether returns, plenums and registers are part of the work, how debris is collected and who will perform the service.

Will duct cleaning fix a musty smell?

Sometimes. Dry dust and old debris can hold stale odors, and removing them can help. A musty odor is different. It can point to a wet drain pan, damp duct liner or a condensate problem, and the moisture has to be stopped first. Suspected growth changes the job from routine cleaning to an inspection and possibly licensed mold remediation.

What if my ducts turn out to be clean?

Then we tell you. Not every home needs service, and we would rather show a homeowner a clean duct and leave than invent a reason to proceed. If the issue belongs with an HVAC repair company or a licensed mold assessment, we tell you that too.
