Commercial HVAC Service in Menifee, Murrieta & Temecula
When a commercial system goes down, it's not just uncomfortable — it costs you business. Left Coast Air installs, repairs and maintains commercial HVAC for small-to-mid-size spaces across Riverside County, from rooftop units to ductless ceiling cassettes.
Commercial HVAC, Done Around Your Business
Commercial comfort systems have different demands than homes: longer runtimes, tighter tolerances for downtime, and equipment like packaged rooftop units and ceiling-cassette mini-splits that most residential-only contractors don't handle. We service both, and we schedule work around your hours wherever possible so your operation keeps moving.
What We Handle
- Packaged rooftop unit (RTU) repair, replacement and installation.
- Ductless ceiling-cassette and multi-zone systems for offices and suites.
- Preventive maintenance contracts to reduce surprise failures.
- Diagnostics and repair on existing commercial equipment.
Rooftop Unit vs. Ceiling Cassette
| Rooftop unit (RTU) | Ceiling cassette | |
|---|---|---|
| Best for | Larger open areas | Zoned offices & suites |
| Ductwork | Typically ducted | Ductless |
| Zoning | Whole-area | Room-by-room |
| Placement | Roof | Drop-ceiling |

Commercial HVAC FAQs
What types of commercial spaces do you service?
We work on small-to-mid-size commercial spaces such as offices, retail units, shops and similar light-commercial buildings, handling both packaged rooftop units and ductless ceiling-cassette systems.
Do you offer commercial maintenance contracts?
Yes. Scheduled preventive maintenance keeps commercial systems reliable and helps avoid the downtime and lost business that come with an unexpected failure. We can set up a maintenance schedule that fits your equipment and hours. See our maintenance plans.
Rooftop unit or ceiling cassette — which is right for my space?
Packaged rooftop units are common for larger open commercial areas, while ductless ceiling cassettes work well for zoned comfort in offices, suites and spaces where running ductwork isn't practical. We'll recommend based on your building and how the space is used.
Can you minimize downtime during a repair or install?
We plan commercial work around your operating hours where possible and prioritize getting critical systems back online quickly, because for a business a comfort failure is also a revenue problem.
