Should I Repair or Replace My Rooftop Unit?

It depends on the unit’s age, condition, repair history, and replacement cost. If repairs are becoming frequent or the unit is near the end of its service life, replacement may make more sense.

A commercial rooftop unit can often last around 15 to 20 years, depending on maintenance, usage, installation, and operating conditions.

The cost varies based on the unit size, equipment type, installation requirements, ductwork, curb changes, labor, and whether a crane is needed. We provide a detailed estimate before starting the work.

The time depends on the size of the unit and the installation requirements. A straightforward replacement may take a day, while larger or more complex projects can take longer.

Not every replacement requires a crane. However, larger packaged rooftop units may need a crane to safely move the old and new equipment on and off the roof.

Permit requirements can vary based on the project and property. For a commercial rooftop unit replacement in Cobb County, the required permits should be confirmed before work begins. Our team can help you understand the requirements for your project.
