Why Greater Houston Homeowners Choose Package Units
All-in-One System Simplicity
Package units combine the outdoor compressor, outdoor coil, and heating components into a single cabinet—eliminating the need for separate indoor and outdoor units. For homes with space constraints or those without existing split-system infrastructure, package units deliver heating and cooling from one self-contained location, simplifying installation and maintenance.
Armstrong Equipment Trust
We install and service Armstrong package units, engineered for durability and reliable operation. Our technicians understand package unit design, refrigerant flow, heating element integration, and warranty support. We maintain relationships with Armstrong because their systems are built to perform in demanding applications.
Flexible Installation Options
Package units can be installed on roofs, on the ground beside homes, or in mechanical rooms—depending on your space and preference. This flexibility is valuable for retrofits, additions, or homes where traditional split systems aren’t practical. Our installation experience covers all placement scenarios.
Lower Refrigerant Leak Risk
Because a package unit’s major components are in one cabinet, refrigerant line exposure is minimized compared to split systems with long runs between indoor and outdoor units. Fewer connection points mean fewer potential leak sources—a significant advantage for long-term reliability.
Convenient Maintenance Access
Most package units are accessible from a single location (rooftop or ground level), making routine service faster and more efficient than coordinating indoor and outdoor unit maintenance separately.

What Houston-Area Homeowners Say
Package Unit Services We Offer
From installation to repair to maintenance, we handle every aspect of package unit service with Armstrong expertise.
Installing a package unit begins with site assessment. We evaluate available installation locations (rooftop, ground-level pad, mechanical room), existing ductwork capacity, electrical service requirements, and your heating/cooling preferences.
Package units are heavier and bulkier than split systems, requiring proper structural support and weather protection. We verify roof load capacity, design proper installation platforms, run electrical service to code, connect ductwork, charge refrigerant, and perform complete system testing. Some installations require rooftop reinforcement or custom weatherproofing—we handle all structural and mechanical work to ensure your system runs safely and efficiently for years. Learn more about package unit installation.
Package unit failures can stem from refrigerant leaks, compressor problems, heating element issues, or control malfunctions. Our technicians test electrical systems, measure refrigerant pressure, evaluate blower operation, and inspect coils and components.
Because package units house multiple systems in one cabinet, diagnosis can be complex—we need to isolate whether the problem is in cooling, heating, air circulation, or controls. We pinpoint the issue, explain what’s happening, and provide repair options. Many repairs (capacitors, relays, blower wheels) are affordable and straightforward; others (compressor replacement, heat exchanger work) require more significant investment. We show you the costs upfront. Discover our package unit repair process.
Regular maintenance extends package unit life and prevents failures that interrupt comfort. Our tune-ups include refrigerant pressure checks, condenser and evaporator coil inspection and cleaning, blower wheel and motor testing, electrical component verification, heating element inspection, and complete system cycling verification.
Houston’s humid climate and occasional dust storms can clog package unit coils more quickly than in other regions. Our maintenance includes coil cleaning to restore efficiency and prevent airflow restriction. We also test both heating and cooling modes to ensure the system transitions smoothly between seasons.

Package Unit Questions Greater Houston Homeowners Ask
A package unit contains all components (compressor, coils, blower, heating) in one cabinet; a split system has the compressor and condenser outside and the evaporator inside, connected by refrigerant lines. Package units simplify installation but sit exposed on rooftops; split systems are quieter because the compressor is outside but require separate indoor and outdoor work.
Yes, if you have a mechanical room or basement with adequate space. Indoor installation protects the unit from weather and reduces noise. However, indoor location requires proper ductwork connections and condensation drainage. Most residential package units in Houston are roof-mounted due to space constraints.
Rooftop package units are louder than split systems because you hear the compressor directly. Noise levels range from 75–85 decibels—similar to a lawnmower or heavy traffic. If your building has upstairs bedrooms, this noise can be noticeable. Sound wraps and vibration isolation pads can reduce rooftop noise if it becomes an issue.
Electric heating uses resistive elements to warm air directly, working instantly when called. Gas heating uses a burner inside the cabinet to ignite gas and heat air—more efficient but requiring gas supply and venting. Gas heating costs less to operate over time; electric heating is simpler. Heat pump package units use refrigerant cycling for efficient heating.
Once yearly, ideally before cooling season begins (March or April in Houston). Annual service includes coil cleaning, refrigerant checks, electrical testing, heating element inspection, and complete system cycling. Houston’s humidity makes annual service especially important—coils clog more quickly here than in dry climates.
Usually, yes—if your existing ductwork is in good condition and properly sized for the new unit. We evaluate your ducts for leaks, blockages, and sizing compatibility. Sometimes duct sealing or cleaning is needed. If ducts are severely damaged or undersized, partial or full replacement may improve efficiency and comfort.
Quality package units last 12–15 years with regular maintenance. After 15 years, repair costs climb as components wear. By year 15–18, most units need replacement rather than continued repair. Proper maintenance (annual tune-ups, timely repairs, regular coil cleaning) extends this lifespan.
When new, efficiency is comparable—both use refrigerant-based cooling and can have similar SEER (cooling) and AFUE (heating) ratings. However, rooftop exposure causes package units to age faster than indoor split-system compressors. After 10 years, maintained split systems often run more efficiently than rooftop package units.
Signs include reduced cooling capacity despite proper refrigerant charge, inability to reach setpoint temperature, or visible rust/corrosion on the coil. We perform pressure and temperature diagnostics to confirm coil function. Sometimes coil cleaning restores performance; severe damage requires coil replacement.
If your unit supports gas heating, yes—though this requires gas line installation, venting work, and control modifications. It’s often less expensive to replace the entire unit with a gas-heating model than to retrofit gas heating into an electric-only unit. We assess feasibility and costs during a consultation.
