We Make Your Air Better
Package Unit HVAC Services in Tyler, TX
A package unit puts heating and cooling in one cabinet outside the house, usually on a slab beside it or on the roof. There is no indoor air handler to find room for, which is exactly why so many East Texas homes use them. The trade-off is that every component lives outdoors, exposed to heat, humidity, and weather year round.
903 HVAC covers all three sides of package unit ownership: installation and replacement, repair and service, and seasonal maintenance. Our licensed technicians (TACLB#39819E) work on them throughout Tyler and East Texas.

All In One Cabinet
What Living Outdoors Does to a Package Unit
In a split system, half the equipment sits in a conditioned closet or attic. In a package unit, the compressor, the coils, the blower, the heating section, and all of the electrical controls share one cabinet outside. Everything is subject to the same sun, rain, dust, and humidity.
That is what shapes the service pattern we see on these systems:
- Corroded electrical connections from constant moisture exposure
- Clogged condenser coils that lose their ability to reject heat
- Cracked cabinet seals that let weather reach components it should not
None of that means package units are a poor choice. It means the maintenance is not optional in the way an owner might get away with on a system that is half indoors. Worn capacitors and contactors, drifting refrigerant charge, and coil fouling are all cheap to address on a schedule and expensive to address after a failure.
We install American Standard package units, built with heavy-gauge steel cabinets, Duration compressors, and Spine Fin coil technology, and we service package units from other manufacturers as well.
Complete Package Unit Care
Our Package Unit Services
Three services cover the full life of an all-in-one system. Each has its own page with our process and the failures we see most.
Package Unit Repair & Service
Not cooling, not heating, weak airflow, breaker trips, or refrigerant leaks. We inspect, test the electrical side, evaluate the refrigerant system and the heating section, then explain the fault before we repair it.
Package Unit RepairPackage Unit Installation & Replacement
Load calculation, equipment selection, removal of the old unit, pad or platform preparation, then installation, connection, and full commissioning. Replacing a package unit is as much a site job as an equipment job.
Package Unit InstallationPackage Unit Maintenance & Tune-Up
Electrical inspection, cooling system service, heating system service, airflow and ductwork assessment, and a cabinet and exterior inspection that catches weather damage before it reaches the components.

Which Package Unit Service Do You Need?
Because one cabinet does both jobs, a single failure can take out heating, cooling, or both.
It Stopped Working
Book a Repair
No cooling, no heating, weak airflow, or a unit that keeps tripping the breaker. Repeated breaker trips in particular should not be reset and ignored. Book package unit repair and we will find the actual cause.
It Has Been a Year or More
Schedule Maintenance
Spring and fall are the natural windows, and a package unit benefits from both because one visit covers the cooling side and the other covers heating. A tune-up also catches cabinet and weather damage early.
The Cabinet Is Failing
Discuss Replacement
Age plus declining efficiency, repairs that keep coming, or damage the cabinet itself cannot come back from. Because everything is in one enclosure, structural damage can end a unit that would otherwise have life left. Talk to us about replacement.

Frequently Asked Questions About Package Unit Services
A package unit contains the entire heating and cooling system in one outdoor cabinet, typically on a slab beside the house or on the roof. A split system divides the equipment between an outdoor condenser and an indoor furnace or air handler. The main practical difference is that a package unit needs no indoor equipment space, while every component is exposed to the weather.
A breaker that trips repeatedly is protecting something, and resetting it without finding out what is a bad idea. Common causes include a failing capacitor or contactor, a compressor drawing more current than it should, corroded connections, or a short in wiring that has been exposed to moisture. Leave the breaker off and book a service call.
Twice a year is the right cadence, with a spring visit covering the cooling side and a fall visit covering the heating side. Package units make a stronger case for that schedule than most equipment because the whole system sits outdoors, where coil fouling, corroded electrical connections, and cabinet seal damage develop steadily rather than seasonally.
Yes. We are an American Standard Customer Care Dealer and that is the line we install, with factory training and genuine parts access behind it, but our technicians repair and maintain package units from other manufacturers regardless of who originally installed them.
