Small to Mid-size Commercial
24/7 Priority Support
Small Commercial vs. Large Commercial
We specialize in small to mid-size commercial HVAC, which covers the vast majority of neighborhood retail, small office buildings, and commercial condos in LA. Larger institutional facilities like high-rise office buildings or hospitals require contractors with large-commercial specialization. We are transparent about this scope—if your project is outside our wheelhouse, we will tell you and refer you to an appropriate contractor.
Commercial HVAC in California is subject to strict regulations. Title 24 energy code often requires a Mechanical Engineer's stamped plans for larger system upgrades. We navigate these requirements, including LADBS commercial permits and EPA-compliant refrigerant handling, to ensure your business stays in compliance.
Commercial Maintenance for LA Businesses
Regular maintenance is critical for commercial properties where system failure affects your bottom line. We offer commercial maintenance programs with scheduled visits—quarterly or semi-annual—to keep your equipment running efficiently and to catch issues before they turn into emergency repairs.
Our maintenance programs provide documented service records, which are essential for property managers and landlords. These records help with compliance and provide a clear history of your equipment's health, which is vital when deciding between a repair or a full system replacement.
Our Diagnostic Approach
When we arrive at your commercial site, we start with a thorough site assessment. We document your current equipment, identify the specific failure points, and look at the broader system health. We don't just fix the symptom; we look at why the problem happened in the first place.
After the assessment, we provide a detailed written proposal. This includes the scope of work, labor, permit costs, and a realistic timeline. We believe the estimate should make sense before anyone touches the equipment, so you can make an informed decision for your business.
Repair vs. Replacement Decisions
I am always honest about whether a system is worth repairing. If a repair is a solid, long-term fix, that is what we will recommend. However, if the pattern of failures suggests the equipment is at the end of its life, I will explain why replacement is the more practical financial decision.
For commercial owners, this decision often comes down to downtime and efficiency. If your current unit is costing you more in frequent repairs and high utility bills than a new, efficient system would, we will present the numbers so you can decide what makes the most sense for your operation.
Commercial Service Costs
Commercial HVAC costs vary based on the complexity of the system and the specific needs of your building. Our diagnostic fees typically range from $175 to $350, and repairs generally fall between $250 and $2,500 depending on the parts and labor required.
Rooftop unit (RTU) service is a common request, with costs ranging from $200 to $500. For full system installations or tenant improvement projects, we provide custom quotes after a site visit. We are committed to transparent pricing so you know exactly what to expect before we begin.
Scheduling and Access
We know that commercial HVAC failure is an emergency. During business hours, our target response for commercial emergencies is 2–4 hours. For after-hours emergencies, we aim to respond within 2 hours. You can reach us 24/7 at (323) 970-3113.
We are experienced in working with property managers and building owners to coordinate access. Whether it involves rooftop equipment, shared walls, or specific building access windows, we plan our work to minimize disruption to your employees and customers.
Specialized Commercial Needs
Restaurants have unique requirements, including makeup air systems for kitchen exhaust hoods and specific rooftop unit placement to manage grease and exhaust. We understand the critical temperature control requirements for food safety and the specific codes that apply to restaurant HVAC.
We also work with tenants and landlords on tenant improvement (TI) projects. We can design and install complete systems for new spaces, coordinate with general contractors, and handle the entire permit process from start to finish.

What Koreatown customers say about commercial hvac
Verified reviews from homeowners in Koreatown and nearby neighborhoods who used our commercial hvac service.
“LC handles all three of our restaurant locations in Koreatown. Rooftop unit on one site went down on a Friday night — they had it running by Saturday afternoon. No service contract drama, just got the job done.”
“Had LC install a Daikin mini split in our 1940s bungalow that never had AC. The work was clean, the unit is incredibly quiet, and our bedroom finally stays cool in summer. Highly recommend.”
