A restaurant with a failed walk-in, an office with a dead rooftop unit and a plant with a blocked main all have the same underlying problem: the building is losing money for every hour the fault persists. We hold both a Texas HVAC licence and a Texas plumbing licence, which means one contractor covers mechanical, plumbing and refrigeration rather than three who each blame the others.
Napps Commercial — Longview & East Texas since 1957
The three systems that stop a business trading are mechanical, plumbing and refrigeration. We are licensed in all three, so a single call covers the building rather than a single trade.
Rooftop and packaged units, split systems, make-up air and the controls that tie them together. Repair, replacement and planned maintenance for offices, retail, churches and light industrial.
Water supply, waste and vent, water heaters, fixtures and gas piping for commercial buildings, plus the drain work that keeps kitchens and restrooms in service.
Walk-in coolers and freezers, ice machines, beer coolers and reach-ins. The equipment where a failure is measured in spoiled inventory rather than discomfort.
Diagnosis and repair on rooftop and split equipment, with the honest assessment of whether repair or replacement is the better spend on an ageing unit.
Planned equipment replacement, sized on a load calculation and scheduled around your trading hours rather than ours.
The workhorse of East Texas commercial buildings. Repair, replacement, curb adaptation and the maintenance that decides how long they last up there.
The equipment differs, but the real difference is that downtime has a price and the building has to keep trading while the work happens.
On a house, a failed air conditioner is uncomfortable. On a commercial building it closes a dining room, empties an office or spoils a freezer full of stock. That changes the right decision constantly — a temporary repair that restores trading today and a proper replacement scheduled for next week is frequently better than the technically ideal fix that keeps you closed. We price and plan around that rather than around the equipment alone.
Commercial AC Repair →Most commercial buildings are served by an HVAC contractor, a plumber and a refrigeration company, which works until a problem sits on a boundary. A condensate drain backing up into a ceiling is arguably all three. Holding both a Texas HVAC licence and a Texas plumbing licence, and working on refrigeration daily, means we can simply fix it rather than establish whose responsibility it is.
Commercial Plumbing →A packaged unit here runs long cooling seasons in high humidity, sits on a hot roof, and gets a fraction of the attention indoor equipment receives because nobody walks past it. Coils load with debris, condensate drains block, and economizer dampers seize in whatever position they were last in. Almost every rooftop failure we attend was visible months earlier to anybody who went up there.
Packaged Units →The businesses that call us least are the ones on a maintenance schedule, which is not a sales line so much as an observation about how commercial equipment fails. Blocked drains, dirty coils, loose belts and low charge are all cheap and quick when found deliberately and expensive when found at the point of failure, usually on the hottest afternoon of the year.
Commercial HVAC →Typical East Texas commercial work — not an exhaustive list.

Scoped, priced and scheduled so the building keeps trading.
We look at the actual equipment and the access to it, rather than quoting from a model number over the phone.
What is being done, what it costs, and what we recommend deferring. Agreed before anyone starts.
Nights, early mornings and weekends where the work would otherwise close you. That is normal for us, not an exception.
Performance verified, findings written up, and anything we noticed that will need attention later flagged in advance.
Most commercial failures announce themselves. These are the announcements.
One contractor, three trades, and a company that has been at the same Longview address since 1957.

What East Texas business owners ask before calling us in.
Yes. We build them around the actual equipment on the building rather than selling a fixed package, because a restaurant with three walk-ins and a make-up air unit needs a different schedule from an office with two rooftop units. The point is to find the cheap problems deliberately instead of meeting the expensive ones at the worst moment.
Yes, and for most of our commercial customers that is the normal arrangement rather than a special request. Replacing a rooftop unit over a weekend or clearing a kitchen drain before opening usually costs less overall than closing during trading hours, even where the labour rate differs.
Yes. We hold both a Texas HVAC licence and a Texas plumbing licence and work on commercial refrigeration daily. That matters most on the problems that sit on a boundary between trades, where separate contractors tend to spend more time establishing responsibility than fixing anything.
Our line is answered by a person at any hour, and commercial calls where trading has stopped or inventory is at risk are prioritised accordingly. We are based in Longview and serve East Texas from here, so response times are a matter of driving distance rather than dispatch from another city.
Constantly — they are the most common commercial equipment in East Texas. We repair and replace them, adapt curbs where the replacement footprint differs, and service the economizers and controls that most maintenance programmes quietly skip.
That is the more useful conversation. We assess remaining life on the equipment you have and tell you which units are worth maintaining and which should be budgeted for replacement, so the spend becomes a planned line item rather than an emergency on the hottest week of the year.
Each commercial trade has its own page with the detail.
HVAC, plumbing and refrigeration from one licensed contractor, scheduled around your trading hours.
Tell us the building type and what has failed. If trading has stopped or inventory is at risk, say so and call — we prioritise those.
