Replacement:
When repair costs exceed 50% of a rooftop unit replacement in Glendale, CA, choose replacement. Our technicians calculate this comparison during every inspection and present the financial analysis.
We handle all of your heating and cooling needs. Our rooftop unit replacement cost depends on the type of unit and building factors. But some models that we replace are:
Most small-to-medium commercial spaces use packaged units that combine a compressor, coils and fans in a single rooftop housing. These self-contained systems cost less to install than split configurations. We replace all major RTU brands and match capacity, efficiency, and control compatibility with your existing setup.
Larger buildings require zone-based cooling that directs air to different sections. Replacement of multi-zone systems demands precise ductwork evaluation and damper reconfiguration. Our team verifies that new equipment connects to your existing distribution system.
Whether your unit has reached service-life limits or failed completely, we handle the full replacement cycle with crane-assisted removal, rooftop unit installation of capacity-matched systems, and final performance testing.
