Commercial HVAC in East Texas is mostly rooftop equipment doing long, hot, humid cooling seasons with very little attention, because nobody walks past a unit on a roof. That single fact explains most of the failures we attend and most of the money businesses here waste on them.
Napps Commercial HVAC — Longview & East Texas since 1957
Offices, retail, restaurants, churches and light industrial across East Texas. Repair when repair is right, replacement when it is not, and maintenance so the choice is yours rather than the equipment.
Diagnosis and repair on rooftop, packaged and split equipment, with a straight answer on whether the unit is worth further investment.
Planned equipment replacement sized on a load calculation, with curb adaptation and crane work handled, scheduled outside trading hours.
The dominant commercial equipment here. Coils, drains, economizers, belts and controls — the parts that decide how many summers it has left.
Scheduled visits built around your equipment rather than a fixed package. The businesses on a schedule are the ones we hear from least.
Commercial duct systems, static pressure problems and the zones that have never been comfortable regardless of what equipment was fitted.
Filtration, ventilation and humidity control for buildings where occupant complaints are the symptom rather than temperature.
Commercial HVAC here fails in a small number of predictable ways, almost all of which are visible in advance.
A packaged unit removes a great deal of water from East Texas air, and all of it leaves through a small drain that sits on a hot roof collecting algae and debris. When it blocks, the pan overflows into the building. We attend more ceiling damage from blocked condensate drains than from actual roof leaks, and clearing one takes minutes if anybody goes up there to do it.
Packaged Units →A rooftop condenser coil loads with pollen, cottonwood, dust and whatever the roof itself sheds. The unit does not stop working; it just rejects heat less well, runs longer, draws more current and eventually trips on high pressure during the hottest week. Because the decline is gradual, most buildings never notice until the unit fails outright.
Commercial AC Repair →Most packaged units here have an economizer designed to use cool outside air when it is available. Left unserviced, the dampers seize, the actuators fail and the linkage corrodes, generally in whatever position they happened to be in. Stuck closed you pay to cool air you could have had free; stuck open you drag hot humid August air into the building and pay to remove it. Either way the building pays, and nothing on the thermostat indicates it.
→A commercial unit past twelve to fifteen years, on obsolete refrigerant, needing a compressor, is usually not worth the repair — but that is a judgement about your building and your budget, not a rule. We give you the repair cost, an honest estimate of what else is likely within two years, and the replacement figure, and let you make the decision with real numbers rather than a recommendation with no arithmetic behind it.
Commercial AC Replacement →General guidance. The assessment decides it, not the table.
| Situation | Usual Direction | Reasoning |
|---|---|---|
| Under 10 years, single component failed | Repair | Plenty of life left and parts available |
| 10-15 years, repeated calls | Assess seriously | Repair spend is approaching replacement value |
| Compressor failure, obsolete refrigerant | Replace | Repair rarely justified against remaining life |
| Multiple units, staggered ages | Plan a programme | Budget replacement over years, not all at once |
| Capacity never suited the space | Replace and resize | Repairing an undersized unit fixes nothing |

Assessed on site, priced in writing, scheduled around your business.
We go up and look at the equipment and its access, rather than quoting from a model number.
What is wrong, what it costs, and what we would defer. Including the option we would choose if it were our building.
Out of hours where a daytime shutdown would cost more than the job.
Performance checked, findings recorded, and anything approaching failure flagged for your budget.
The gradual symptoms matter more than the sudden ones, because they are the ones you can still act on cheaply.
Licensed, local, and straight about whether your equipment is worth another repair.

What building owners and facility managers ask us most.
It depends on the equipment type, what has actually failed and how the roof is accessed, which is why we assess on site rather than quoting a figure over the phone. You get a written price before work starts, and where replacement is the better spend we will say so and give you that number too rather than selling you a repair we do not believe in.
Twice a year is the usual baseline, but rooftop equipment in East Texas frequently justifies more — quarterly attention to coils and condensate drains in particular. Restaurants and buildings with heavy grease or dust loading need more again. We build the schedule around what is actually on your roof rather than selling a standard package.
Yes, including curb adaptation where the replacement footprint differs from the original, and the crane set itself. We schedule these outside trading hours as a matter of course, because for most businesses the cost of closing exceeds any difference in labour rate.
Yes, and that is a large share of our commercial work. We start with an assessment of what is actually on the building and its condition, so you get an honest baseline rather than inheriting assumptions from the previous contractor.
Often it is not. Persistent single-zone complaints are frequently airflow, duct balance or a control problem rather than capacity, which matters because replacing the equipment does not fix any of those. We test before recommending, so you are not buying a unit to solve a duct problem.
Yes. Commercial replacement is rarely something a business planned for in the month it becomes necessary, so payment options are worth discussing before the decision rather than after it.
Repair, replacement, rooftop units and the plumbing side.
On-site assessment, written pricing, and work scheduled so your building keeps trading.
