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.

Our team removes your existing system using a crane and keeps the existing structure in place. We’ll then set a new unit, reattach all connections and complete the installation.
We charge refrigerant to specification, test all electrical controls and verify airflow distribution throughout your building.
Manual J calculations form the foundation of correct sizing. We measure your space, document existing ductwork and assess thermal load from:
The resulting capacity recommendation prevents efficiency losses and comfort problems that undersizing and oversizing create.
Your replacement unit receives capacity recommendations from engineering analysis, not guesswork.

Modern rooftop units operate at SEER2 ratings 40-60% higher than equipment from 2005 or earlier. Variable-capacity compressors modulate output to actual demand, avoiding constant-speed operation of older models. Many newer systems integrate with building automation for demand-responsive control.
You might even qualify for rebate programs to offset your expenses.

| Service Detail | Why It Matters |
|---|---|
| Quiet inverter operation — 20+ dB quieter | A new variable-speed system runs noticeably quieter than an old single-stage |
| All-electric / heat-pump readiness | Replacing now aligns with California's gas phase-out and keeps you rebate-eligible |
| Match the SEER2 tier to the rebate minimum | The rebate often starts at a specific efficiency step — cross it and payback comes faster |
| Full changeover, not condenser-only | A new outdoor unit on an old indoor coil drops efficiency and can void the warranty |
| New refrigerant needs a matched coil and line set | An R-32 / R-454B system won't perform on mismatched R-410A parts |
