Package Unit HVAC Services in North Texas:
Repair, Installation and Rooftop Maintenance

A package unit puts the whole system in one weatherproof cabinet outside the house: cooling components, heating, blower and controls together, connected to the home by ductwork alone. That design solves the problem of a house with nowhere to put an indoor unit, and it creates a maintenance profile no split system has. Graco Heating & Air services ground-mounted and rooftop package units across North Texas under TX License #TACLA00017212E.

Everything in One Cabinet

What a Package Unit Is, and Who It Suits

These self-contained systems house the air conditioner or heat pump components, a gas furnace or electric heat strips, the blower motor and air handler, and the control electronics in a single outdoor cabinet. Nothing lives in your attic or closet.

Slab Foundations, No Crawl Space

Common across North Texas. With no crawl space and limited indoor mechanical room, a package unit is often the only sensible configuration.

Mobile and Modular Homes

Manufactured housing is built around this equipment type. We also cover it on our mobile and modular home HVAC page.

Rooftop Installations

Standard on light commercial buildings and some residential properties. See our commercial HVAC page for rooftop unit work.

Full Weather Exposure

Every component sits outdoors year round. Corrosion from rain and humidity, UV degradation and wind-blown debris are constant, not occasional.

Package Unit Down?

Because heating and cooling share one cabinet, a single failure can take out both. Call us and describe whether you have lost cooling, heat, or both.

Our Package Unit Services

Ground-mounted and rooftop, residential and light commercial.

Package Unit Repair

One cabinet means integrated system testing rather than checking two halves separately. We work through cooling faults, heating faults and the dual-mode problems that only show up on this equipment type.

  • Complete system failures
  • Heating and cooling mode faults
  • Component-specific repairs

Package Unit Installation

Location planning and pad or curb preparation matter as much as the equipment. As Armstrong ProTeam dealers we install the A4GP gas and electric series with an aluminized steel heat exchanger and integrated control board.

  • Load calculation and location planning
  • Ductwork integration
  • Ground and rooftop placement

Package Unit Maintenance

Outdoor exposure earns this equipment a spring and fall schedule. Anti-corrosion treatment and terminal cleaning are part of the visit, and rooftop units get their own safety protocols.

  • Spring and fall seasonal service
  • Corrosion and terminal treatment
  • Rooftop unit specialization

Which Package Unit Service Fits?

The unit has stopped, or one mode has

Book package unit repair. Losing cooling but keeping heat, or the reverse, narrows the diagnosis considerably, so mention which one when you call.

The cabinet looks rough after a few Texas summers

Corrosion, UV damage and packed-in debris are the standard wear pattern for equipment that lives outside. Package unit maintenance addresses it before it reaches the electrical terminals.

You are replacing an aging package system

Start with package unit installation. Existing ductwork usually carries over, which keeps a replacement simpler than a conversion to a split system.

You have a mobile home or a light commercial building

Both are core package unit territory. See mobile and modular home HVAC or commercial rooftop units for how we handle each.

Rooftop Units and the Equipment We Install

Elevated equipment needs a different approach on the ground and on the roof.

Rooftop Service Protocols

Rooftop service requires specialized protocols before a technician touches the unit:

  • Safety equipment inspection
  • Structural evaluation
  • Weather monitoring
  • Fall protection systems and proper tool lifting

Package Unit Questions

What North Texas property owners ask about all-in-one systems

A split system divides the equipment between an outdoor condenser and an indoor furnace or air handler. A package unit houses everything in one weatherproof cabinet outdoors: the cooling components, a gas furnace or electric heat strips, the blower motor and air handler, and the control electronics. Your home connects to it through ductwork only.

Package units excel for homes with limited indoor mechanical space, slab foundations without crawl spaces, mobile and modular homes, additions where ductwork already exists, commercial residential properties, and rooftop installations. If there is nowhere practical to put an indoor unit, this is usually the answer.

Because every component is outdoors all year. Constant exposure brings accelerated corrosion from rain and humidity, UV degradation of components, and debris accumulation from wind. Our service includes anti-corrosion treatment along with terminal cleaning and tightening, which is not something a split system's indoor half ever needs.

Yes. Rooftop package units are a core part of our light commercial work, and rooftop service follows specialized protocols including safety equipment inspection, structural evaluation, weather monitoring and fall protection systems. Our commercial HVAC page covers rooftop unit work in more detail.
