Rooftop HVAC systems may develop performance problems before they stop operating completely. Scheduling an inspection when symptoms first appear can help prevent extended interruptions.
Inconsistent indoor temperatures. Certain rooms or building zones remain uncomfortable even when the thermostat settings are correct.
Frequent system shutdowns. The rooftop unit repeatedly cycles off, trips electrical protection, or fails to restart.
Unusual operating noises. Grinding, rattling, or squealing may indicate worn motors, damaged bearings, or loose components.
Increasing energy bills. Rising utility consumption without a corresponding change in building usage may indicate declining equipment efficiency.
Repeated repair calls. Frequent compressor, refrigerant, electrical, or control problems can make rooftop unit replacement a practical option.
Commercial rooftop units, commonly called RTUs, contain heating, cooling, and air-moving components within a packaged system installed on a building’s roof. These systems often serve offices, retail stores, restaurants, warehouses, and other commercial facilities.
All Airs Heating, Cooling & Plumbing diagnoses, repairs, and replaces commercial rooftop equipment. Our technicians evaluate system operation, building requirements, and equipment condition before recommending a solution.
Rooftop units operate outdoors, exposing components to rain, direct sunlight, debris, and seasonal temperature changes. Extended operating hours can also increase wear on motors, electrical connections, and mechanical components.
Our technicians investigate common RTU problems involving compressors, condenser fans, blower assemblies, belts, refrigerant circuits, electrical components, gas heating equipment, and thermostats.
Troubleshooting may include checking refrigerant conditions, testing electrical components, evaluating airflow, and examining control signals. We identify the cause of the malfunction before determining which components require repair.
For equipment problems affecting other commercial heating and cooling configurations, our commercial HVAC repair services provide broader diagnostic and repair support.
Commercial rooftop unit replacement becomes necessary when equipment deteriorates, major components fail, or the existing system no longer meets the building’s heating and cooling demands.
Replacement planning begins with evaluating the current unit’s capacity, age, operating history, and performance. Our technicians also consider building occupancy, ductwork, electrical requirements, ventilation, and existing temperature controls.
Proper installation requires attention to rooftop mounting conditions, equipment dimensions, curb compatibility, duct connections, and access requirements. These factors can affect equipment selection and installation scheduling.
All Airs provides commercial HVAC installation and replacement for businesses needing new equipment or planned system upgrades.
Repair may be appropriate when the rooftop unit is relatively new, the malfunction is isolated, and the equipment still operates efficiently.
Replacement deserves consideration when major repairs become frequent, energy consumption increases, or the unit struggles to maintain building temperatures. Many commercial rooftop units operate for approximately 15 to 20 years, although maintenance history and operating conditions influence their actual lifespan.
Our technicians review repair costs, equipment condition, and remaining service life to help property managers evaluate their options.
All Airs works with commercial heating and cooling equipment from Bryant, Carrier, Lennox, and Trane. Rooftop configurations may include packaged air conditioners, gas-electric units, and packaged heat pump systems.
Our technicians consider the specific equipment design when diagnosing problems or planning replacement. Compatibility with existing controls, electrical infrastructure, and air distribution systems is assessed before installation.

Many rooftop replacements require lifting equipment to remove the existing unit and position the replacement. The equipment size, roof access, and building configuration determine the appropriate installation method.
Existing ductwork may remain in place when its size, condition, and airflow capacity are suitable for the replacement equipment. Modifications may be necessary if the new unit has different connection requirements.
Installation time depends on equipment availability, roof access, electrical work, and whether mounting or ductwork modifications are required. Our technicians evaluate these factors when planning the project.
Yes. Many commercial packaged rooftop systems contain heating and cooling equipment within one cabinet. The specific configuration depends on the building’s needs and the installed equipment.
Routine inspections can identify deteriorating belts, dirty coils, restricted airflow, and electrical problems before they cause equipment failures. Our commercial HVAC maintenance services include customized preventive care for rooftop units and other commercial equipment.
