RTU Diagnostics
We test refrigeration circuits, gas heat sections, blower assemblies and controls, reading fault codes and measuring pressures to identify why a rooftop unit is not heating, cooling or ventilating properly.

Rooftop Unit Repair and Installation in Roswell, GA
Rooftop units, often called RTUs, are self-contained packaged systems that heat, cool and ventilate offices, retail spaces, restaurants, schools and government buildings. Because they sit on the roof, problems can go unnoticed until occupants complain or a tenant loses cooling during a busy afternoon. Our team provides rooftop unit repair in Roswell along with full replacement and new installations for commercial and government facilities. We repair compressors, condenser fans, blower motors and belts, gas heat sections, economizers and control systems, and we handle roof curb adapters, crane coordination and startup for new equipment. Whether you manage a single storefront or a building with multiple units, we focus on restoring comfort quickly, communicating clearly with facility staff and keeping the roof and building protected throughout the work. Planned replacements can be scheduled to minimize disruption to operations.

Rooftop Unit Repair and Installation Services in Roswell
Belt and Blower Service
Worn belts, misaligned pulleys and failing bearings reduce airflow and cause noise. We replace belts, adjust tension, lubricate or replace bearings and service blower motors to restore proper airflow.
Economizer Repair
Economizers use outside air for free cooling when conditions allow. We repair stuck dampers, failed actuators and faulty sensors so units use outdoor air correctly and avoid humidity problems.
Gas Heat Sections
We inspect and repair rooftop gas heat components, including igniters, flame sensors, inducer motors, gas valves and heat exchangers, verifying safe combustion and reliable heating through colder months.
Unit Replacement
For failing or outdated units, we size replacements to the building load, coordinate crane lifts, install curb adapters when needed and complete startup checks before returning the space to service.
Preventive Maintenance Plans
Scheduled maintenance for multiple rooftop units includes filter changes, coil cleaning, belt checks and control verification, with written reports that help facility managers plan budgets and future replacements.

FAQ
Rooftop Unit Repair and Installation FAQs
Answers to the questions Roswell customers ask us most. Still unsure? Call (770) 661-0066.
How often should commercial rooftop units be serviced?
Most rooftop units benefit from service at least twice a year, before cooling and heating seasons, with more frequent filter changes for restaurants, dusty environments or high-occupancy spaces. Roswell's spring pollen can clog filters and coils quickly. A regular schedule keeps belts, economizers and gas heat sections operating reliably across multiple units.
How long does a rooftop unit replacement take?
Many like-for-like replacements are completed in a single day once equipment arrives, including the crane lift, connections and startup. Projects needing curb adapters, electrical changes, gas piping work or permits take longer. Equipment lead times also affect scheduling. We provide a clear timeline in our replacement plan so you can coordinate with tenants and staff.
What factors affect rooftop unit replacement cost?
Major factors include unit tonnage, heating type, efficiency level, whether the existing curb fits the new unit, crane requirements, building access and any electrical or gas updates. Economizer and control options matter too. After a site assessment, we provide an upfront, itemized quote so you can compare options and plan your budget.
Can you work on our rooftop units without disrupting business?
In most cases, yes. Many repairs can be completed while the building stays open, and we coordinate access with facility staff. For replacements that require shutting units down, crane lifts or noise, we schedule work around operating hours when possible and plan staging carefully to keep occupants comfortable and safe.
When should a rooftop unit be replaced instead of repaired?
Replacement makes sense when a unit is aging, needs a major component such as a compressor or heat exchanger, has frequent breakdowns, uses outdated refrigerant or no longer meets the building's needs. Rising energy costs are another signal. We give facility managers a straightforward comparison of repair costs, reliability and long-term operating expenses.
