Napps has worked out of the same Longview address since 1957, under the same family. We hold both a Texas HVAC licence and a Texas plumbing licence, which means one call covers cooling, heating, plumbing and commercial refrigeration — and the problems that sit between those trades get fixed rather than passed between contractors.
Napps Cooling, Heating & Plumbing — Longview & East Texas since 1957
Residential and commercial work across East Texas. The same technicians who service your cooling in July know your heating in January, because on a heat pump it is the same machine.
Repair, installation, maintenance and 24/7 emergency cooling. In an East Texas August a failed system is a real problem, and we treat it as one.
Furnaces, heat pumps and the safety checks that matter on any gas appliance. Equipment here sits idle nine months a year, which is exactly why it fails on the first cold night.
A fully staffed plumbing division since 2012 — leaks, drains, repairs, fixtures, gas lines and water treatment, by licensed Texas plumbers.
Repair and replacement, tank and tankless, sized for how the household actually uses hot water rather than matched to whatever failed.
Blocked drains, main lines, camera inspection and hydro jetting. Where a line keeps blocking we find out why rather than clearing it again.
Rooftop packaged units, commercial plumbing, walk-in coolers and ice machines — scheduled around your trading hours rather than ours.
Most HVAC advice is written for somewhere else. Long humid cooling seasons, mild winters and hot attics change which answers are right.
At sixty percent indoor humidity a house feels clammy at any setting, and the usual response is to drop the thermostat — which raises the bill without fixing the sensation. Air conditioning dehumidifies only while it runs, which is precisely why oversized equipment produces cold, damp houses. Sizing on a load calculation rather than copying whatever tonnage was there before is the single most consequential decision in a replacement, and it is the one most often skipped.
AC Installation →Most ductwork here runs through an attic that passes a hundred and thirty degrees in summer. Supply-side leaks deliver air you paid to cool straight into that attic. Return-side leaks are worse: they pull hot, humid, dusty attic air into the system past your filter, raising your cooling load and your indoor humidity at once. Both are invisible, both are common, and both cost far less to fix than the larger system people are usually offered instead.
Ductwork Services →A furnace here works a few hundred hours a year and sits idle for the other nine months. That sounds like an advantage, and mostly it is, but long dormancy is hard on ignition components and seizes blower motors. It is why failures cluster on the first genuinely cold night rather than spreading across a winter — everything is asked to start at once, and the ones that will not, do not.
Heating Services →We hold a Texas HVAC licence and a Texas plumbing licence and work on commercial refrigeration daily. That matters most on problems sitting on a boundary — a ceiling stain that could be a condensate line or a supply leak, a gas line feeding heating equipment, a drain serving refrigeration. One call resolves it instead of two contractors establishing whose responsibility it is.
Plumbing Services →Indicative. Diagnosis on site confirms it.
| What You Notice | Usual Cause | Where to Start |
|---|---|---|
| AC runs but will not cool | Dirty condenser coil, low charge or airflow | AC repair diagnosis |
| One room never comfortable | Duct run, return path or balance | Ductwork assessment |
| House feels clammy | Humidity, often oversizing or duct leakage | Humidity and airflow check |
| No heat on the first cold night | Ignition or a part that sat idle all year | Heating repair |
| Drain blocking repeatedly | Grease, roots or a structural fault | Camera inspection |
| Hot water running out early | Undersized or failing water heater | Water heater assessment |

What East Texas homeowners and businesses ask us most.
Yes. The line is answered by a person at any hour rather than an answering service that takes a message. No cooling in a heatwave, no heat during a freeze, an active leak, a blocked main or commercial refrigeration with stock at risk all go ahead of routine work.
It depends on the fault, which is why we diagnose on site and agree an upfront flat-rate price with you before starting. Anyone quoting firmly over the phone is guessing. Where a repair is not a sensible spend on ageing equipment we will tell you and give you the replacement figure alongside it.
Yes. We added a fully staffed plumbing division in early 2012, and we hold both a Texas HVAC licence and a Texas plumbing licence. It matters most on problems that sit between the trades, where separate contractors often spend more time establishing responsibility than fixing anything.
Longview and the East Texas counties around it — Gregg, Harrison, Smith, Upshur, Rusk, Wood, Cass, Panola, Marion and Morris. Every town we cover has its own page on the service area section of this site.
Since 1957. Roy L. Napps founded the company in Longview that year, and his son Eddie has owned and run it since 1975. We operate from a 23,000 square foot facility on Cotton Street that includes an engineering department and sheet metal fabrication alongside the service operation.
Yes, on system replacement, heat pumps, water heaters and major plumbing work. We quote the job first and then go through the payment options with the written price in front of you.
