What that means for ducts
Mixed-era stock
DeSoto splits across build eras — 7% pre-1980, 13% since 2010 — so two houses on the same street can need completely different work. It is the case where guessing from the curb is worst, and where a camera before a quote saves the most money.
That is a reading of the city’s stock, not a diagnosis of your home. Which of it applies to you is exactly what the camera settles — and why we would rather run one than quote from a postcode.
02Working in DeSoto
The part that changes from street to street.
Most of DeSoto is 1990s and 2000s subdivision, and the builder practice of that period turns up in nearly every house we open. Return air was frequently carried in a panned joist bay or a stud cavity rather than in sealed duct, which means the return path is framing lumber, drywall and whatever else happens to share that cavity. Those cavities were never airtight, so a system with a panned return is not only pulling air from your rooms. It is pulling from the wall, from the attic edge, sometimes from the garage side of a shared wall. You can clean every supply branch in the house and the return will go on feeding the coil with attic dust within weeks. Electric equipment is the norm here, so the coil runs ten months a year and is the surface where the consequence shows first. Sealing the return path is the repair that lasts; cleaning without it buys a season.

03UV Air-Purification Light Installation — in this stock
When a treatment is actually indicated.
Treatments are offered on evidence, not on age. In mixed stock that means the camera decides: staining, animal intrusion, or a documented moisture event. No indication, no treatment — and our technicians are not paid on what they add.
Will a UV light purify the air in my whole house?
Not by itself, and we'll never claim otherwise. Air moves past the lamp too quickly for much single-pass effect; UV's real work is keeping continuously wet surfaces — coil area, drain pan — clean, which prevents the microbial growth and odor that start there.
How often does the bulb need replacing?
Annually, as a rule. Germicidal output fades long before the visible glow does, so a lamp can look alive while doing little.

05Questions
Asked in DeSoto, answered straight.
Will a UV light purify the air in my whole house?
Not by itself, and we'll never claim otherwise. Air moves past the lamp too quickly for much single-pass effect; UV's real work is keeping continuously wet surfaces — coil area, drain pan — clean, which prevents the microbial growth and odor that start there. Think of it as surface hygiene that complements filtration, not a force field.
How often does the bulb need replacing?
Annually, as a rule. Germicidal output fades long before the visible glow does, so a lamp can look alive while doing little. We put a dated label at the unit when we install, show you the swap procedure, and the replacement is a simple, inexpensive routine from there.
We had the ducts cleaned two years ago and the dust came right back. Why?
That is the signature of a leaky return. If part of your return path is a framing cavity rather than sealed duct, the system draws attic and wall dust in continuously, and no cleaning downstream of that can keep up. We put the camera and a smoke check on the return side first, because that is the finding that explains the complaint.
There is a faint garage smell in the house when the system runs.
Take that one seriously. It usually means the return is drawing from a cavity connected to the garage, which brings exhaust and stored chemical fumes into the air you breathe. It is a sealing repair, not a cleaning, and it is worth doing before anything else on the list. We document where it is entering so the repair can be aimed rather than guessed.
Our house is from 1998. Is the flex duct at the end of its life?
Close to it in places. Twenty-five years in a DeSoto attic leaves the insulation compressed at every strap and the inner liner brittle in the runs that get the most heat. We inspect and photograph before quoting so you can see which branches are genuinely worth keeping. Cleaning a run whose liner has torn is money spent on something that will not improve.
