In Valencia, we service rooftop units (RTUs), split systems, packaged units, and commercial mini split systems. Our CSLB licensed technicians are experienced with the higher-capacity equipment, more complex controls, and stricter code requirements that differentiate commercial from residential HVAC work.
Valencia is a large master-planned community within Santa Clarita, known for its mix of retail centers, offices, and restaurants. The local commercial building stock ranges from newer energy-efficient builds to older properties with aging HVAC systems. We understand the specific challenges these buildings face, from rooftop access in strip malls to coordinating service around business hours. Our goal is to provide practical, honest service that keeps your business running.

Common Commercial HVAC Problems in Valencia
Valencia's hot summers put a heavy load on rooftop units and split systems. Condenser coils clog with dust and debris from nearby construction or landscaping, causing high head pressures and reduced cooling. Refrigerant leaks are also common in aging commercial equipment, often due to vibration or corrosion on rooftop units.
Another pattern we see is thermostat and control failures, especially in spaces with multiple zones or outdated building automation systems. For restaurants, makeup air and exhaust systems present unique challenges, including grease buildup in kitchen hoods. These issues often surface during peak business hours, which is why we prioritize emergency response for commercial customers.
Commercial Building Stock in Valencia
Valencia's commercial properties include strip malls, standalone retail buildings, medical offices, and restaurants. Many of these buildings were constructed between the 1980s and early 2000s, meaning their HVAC systems range from original equipment to recent retrofits. Older rooftop units may still use R-22 refrigerant, which is being phased out and can be costly to recharge.
Newer developments often have more efficient equipment but may have proprietary controls or complex zoning systems. We evaluate the building's age, ductwork condition, and electrical infrastructure before making recommendations. Our experience with mixed-age commercial buildings helps us spot common issues like undersized ductwork or inadequate insulation that affect system performance.
Our Commercial HVAC Diagnostic Process
When we arrive at your Valencia commercial property, we start with a thorough assessment. We check the system type (RTU, split, package, mini split), measure airflow, test electrical components like capacitors and contactors, and check refrigerant pressures. For rooftop units, we inspect the condenser coils, fans, and gas heat exchangers if applicable.
We also look at the building side: supply and return ductwork condition, thermostat or control system functionality, and any signs of air leakage. We document all findings and provide a clear explanation of what's working and what needs attention. The diagnostic fee is applied to any repair work, so you're not paying extra for the inspection if we do the repair.
Repair or Replace Your Commercial HVAC System?
The decision to repair or replace a commercial system depends on several factors. Age is a major one: if the system is over 12-15 years old and needs costly repairs like a compressor or coil replacement, replacement often makes more financial sense. We also look at the refrigerant type — R-22 systems become expensive to maintain as the refrigerant is phased down.
For newer systems, most repairs are worthwhile. We'll give you a written estimate and explain the trade-offs. If the repair cost is less than 50% of a new system and the unit is in good condition otherwise, we'll recommend repair. But if the system has a history of breakdowns, high utility bills, or uneven temperatures, we'll honestly advise replacement. We carry multiple brands and can design a system that fits your space and budget.
Cost and Rebate Factors for Commercial HVAC in Valencia
Commercial HVAC costs vary widely based on system size, complexity, and site conditions. For diagnostic and repair work, expect $175–$350 for a diagnostic, $250–$2,500 for most repairs, and $200–$500 for rooftop unit service. For new installations, call for a quote — we price each project individually based on equipment, ductwork modifications, permit fees, and labor.
Rebates may be available through Southern California Edison or the Los Angeles Department of Water and Power for installing high-efficiency commercial HVAC equipment. We can help you identify potential rebates for your project, but we don't guarantee specific amounts. Proper documentation of old equipment disposal and new system efficiency ratings is required for rebate applications.
Access and Scheduling for Commercial HVAC Service
We schedule commercial service in Valencia with minimal disruption to your business. For rooftop units, we coordinate access through your property manager or building owner. If the unit is on a roof without a ladder, we'll arrange for roof access via interior staircase or exterior ladder as needed. We also work within your business hours — early morning, after-hours, or weekends are possible.
For emergency commercial calls, we prioritize response during business hours. Our target is 2–4 hours for a commercial emergency during daytime, and within 2 hours after hours. Emergency calls are answered within 30 minutes by phone, so you're never left waiting. We understand that HVAC failure in a retail store, restaurant, or office can mean lost revenue — we get there as fast as possible.
Common Commercial HVAC Mistakes in Valencia
One mistake we see is waiting too long to schedule maintenance. Commercial systems that aren't serviced regularly develop small problems that become big ones — like dirty filters causing frozen evaporator coils, or loose belts leading to blower motor failure. Another common issue is ignoring rooftop access safety, which can lead to accidents and liability.
Another mistake is buying the cheapest system without considering long-term efficiency and reliability. We also see improper refrigerant handling from unlicensed contractors, which can damage the compressor and lead to costly repairs. Our advice: trust a CSLB-licensed contractor who follows proper procedures. We don't cut corners because we know the system has to keep your business comfortable.
Health and Safety Considerations for Commercial HVAC
Commercial HVAC systems directly affect indoor air quality, which is critical for customer and employee health. In Valencia's dry climate, proper humidity control and ventilation are important. For restaurants, we pay special attention to makeup air systems and exhaust hoods — they must comply with fire codes and maintain proper air balance. In medical offices, filtration and air changes per hour are key.
Carbon monoxide (CO) testing is part of our service for gas-fired rooftop units and furnaces. We also check drain lines and condensate pans to prevent mold and bacteria growth. Proper airflow and filtration can reduce the spread of airborne illnesses. We're EPA-certified and follow all safety protocols for refrigerant handling and electrical work.
How to Decide Between Repair and Replacement
Start by knowing the age of your system. Most commercial units last 12-15 years with proper maintenance. If yours is older and needs a major repair (compressor, coil, or heat exchanger), replacement is usually the better long-term investment. Also consider the refrigerant — R-22 systems are becoming expensive to maintain. If repair costs are low and the system runs well, repairing makes sense.
We'll give you a written estimate that breaks down the options. We don't pressure you into replacement if a repair will do the job. But if the system is inefficient, breaking down often, or costing too much in utilities, we'll explain why replacement saves money over time. Our goal is to give you the information you need to make the best decision for your business.

What Valencia customers say about commercial hvac
Verified reviews from homeowners in Valencia and nearby neighborhoods who used our commercial hvac service.
“Our AC stopped working during a heat wave and LC had a technician here within two hours. He diagnosed a bad capacitor, had the part on his truck, and fixed it on the spot. Fair price, no upsell. Will use again.”
“Our furnace wasn't heating evenly upstairs. LC found that half of our ductwork in the attic had separated and was blowing hot air into the attic. Repaired everything and now every room heats equally. Professional and transparent.”
