USI Service
USI Paint Booth Service and Repair
Independent service for USI Italia and Chronotech booths. Controls, motors, airflow, and heat refreshed and repaired on-site in Denver, Dallas–Fort Worth, and Tampa Bay.
What we do
What we do on USI booths.
USI Italia is an Italian booth manufacturer, and Chronotech is one of its booth lines. What's on your floor is generally a downdraft cabin with an air make-up unit, heat package, and electronic controls. USI has a long-installed base, and on higher-hour booths, control, motor, and airflow components often need a refresh to get finishes and cycle times back.
Spray Booth Services provides independent service for USI booths, along with all makes and models. We're a division of John Baker Sales, in business since 2003, and paint booths and the compressors that feed them are all we work on. Whether you need a repair or scheduled maintenance, we'll find the real cause and explain it in plain terms.

How a service visit works
From first call to a booth that runs right.
You call or send the form
Call (888) 912-6684 or use the request form. Tell us it's a USI booth, what it's doing, and when it started. A photo of the data plate helps.
We respond within one business day
Every request gets a reply within one business day so we can ask the right questions and set a time.
On-site diagnosis
A technician checks airflow, filters, heat, dampers, and controls on your booth as it's actually configured, not from a generic spec sheet.
Clear explanation and quote
We walk you through what we found, what it takes to fix, and what can wait. You approve before work starts.
Repair or schedule
We fix it on the visit when we can, or schedule the repair, parts, or maintenance around your production.
Common USI booth problems
Most USI calls start with an intermittent booth, not a dead one. The usual patterns:
- A booth that heats, runs, then drops out, often a weak flame signal, marginal gas pressure under sustained draw, or a high-limit trip as airflow falls off.
- Slow or uneven cure from a damper not reaching its cure position or a sensor reading an unrepresentative spot.
- “Bad control board” calls that turn out to be a failed sensor, a burned contactor, a loose terminal, or a drive faulting for a downstream reason.
- Filters run past their life because a gauge with plugged tubing hasn't moved in months.
- Worn seals, sagging doors, and fogged lenses on high-hour cabins.
Our article on USI booth service goes into each of these in more detail.
What you can check yourself
Some of this is shop-level work you don't need a technician for:
- Read and log the manometer at the same time each day. The trend matters more than any one number.
- Change intake and exhaust filters on readings and a schedule, not on complaint.
- Keep floor grates clear and the cabin swept.
- Wipe light lenses and note any that look yellow or dim.
- Listen for new fan noise and check that belts aren't slipping.
- Inspect door seals for tears, flattening, and gaps.
Logging the manometer is the cheapest early warning you have. See how to read a paint booth manometer.
When to call a technician
Stop running the booth and call for a burner that lights and drops repeatedly, any smell of gas, a breaker tripping more than once, a new fan noise, a damper that won't move, a bypassed safety device, or a finish problem that persists after fresh filters. Those are paint booth repair jobs.
If you're not sure how much life is left in the booth, a Booth Health Check gives you a technician's view before you budget. Smart Filter Monitoring can email you when filter airflow says it's time to change.

Questions & answers
USI booth service questions
Who can service a USI Italia booth?
Any qualified independent technician who works on downdraft cabins, air make-up units, and gas heat packages. Whoever shows up should read your booth's documentation instead of assuming a configuration.
Why does my booth heat up and then quit?
Most often a flame signal issue, a gas supply condition that only appears under sustained load, or a limit device tripping because airflow across the burner dropped as filters loaded.
What filters does a Chronotech booth take?
Filter sizes and media depend on cabin size and build, so measure your frames and confirm against your documentation. Intake and exhaust media are usually different products on different schedules.
Are you a USI dealer or authorized service center?
No. Spray Booth Services is an independent service company. We are not affiliated with or endorsed by USI, and we'll tell you if something needs to go back to the manufacturer.
Can you service a booth you didn't install?
Yes. We work on booths regardless of who sold or installed them.
