I'm Leo, and I've spent over 20 years in this industry. I know that commercial equipment requires a different approach than residential units.

Common Commercial Cooling Failures in Tujunga
In the foothills of Tujunga, commercial rooftop units (RTUs) often face unique challenges. The most common issue we see is high-pressure lockout caused by dirty condenser coils. Because these units are exposed to dust, smog, and local debris, the coils get coated quickly. When the coil is blocked, the system can't reject heat, the pressure spikes, and the safety switch trips to prevent compressor failure.
We also see frequent issues with economizer dampers getting stuck. In our climate, these dampers are supposed to bring in cool outside air when possible, but if they get stuck in the wrong position, they can overload the cooling system or pull in hot, humid air. We check these mechanical components during every diagnostic to ensure your system isn't working harder than it needs to.
Navigating Tujunga's Hillside and Commercial Layouts
Tujunga’s geography presents specific logistical hurdles for HVAC service. Many commercial properties are built on slopes or in tight canyon areas where rooftop access isn't as simple as pulling a truck up to the front door. We plan our service calls around these site-specific constraints, ensuring we have the right ladders and safety equipment to reach your units without damaging your property or landscaping.
Because of the elevation changes and sun exposure in the San Gabriel foothills, some parts of a commercial building may stay significantly warmer than others. We look at the entire system, including duct distribution and thermostat placement, to make sure your repair actually solves the comfort issue rather than just masking a symptom.
Our Approach to Commercial Diagnosis
When you call us for a commercial AC repair, we don't just show up and start swapping parts. We follow a strict diagnostic process: we check the electrical components like contactors and capacitors, verify refrigerant levels, and inspect the airflow across the evaporator coil. We want to know exactly why a part failed before we replace it.
If your system is tripping a breaker or locking out, we use our gauges and meters to find the root cause. Whether it's a failing compressor, a bad control board, or a simple sensor issue, we explain what we found in plain English. You’ll get a written estimate for the repair so you can make an informed decision for your business.
Repairing vs. Replacing Commercial Equipment
I’m often asked if a unit is worth fixing. My answer depends on the age of the equipment and the cost of the repair. If your RTU is 10 years old and just needs a new contactor or a coil cleaning, a repair is usually the right move. However, if the compressor is failing or the heat exchanger is cracked on an older, inefficient unit, I will be honest with you about the long-term costs.
We don't push for replacement unless it truly makes financial sense for you. My goal is to keep your existing equipment running reliably for as long as possible. If the repair costs start to approach the value of a new system, we will sit down and look at the numbers together so you can decide what’s best for your bottom line.
Understanding Commercial Repair Costs
Commercial AC repair pricing varies based on the size of the unit and the complexity of the failure. A standard diagnostic fee covers the time it takes for a technician to get on the roof, open the panels, and identify the fault. From there, the cost depends on whether we are replacing a $200 capacitor or a $1,000+ control board.
We provide transparent, written estimates before we turn a single screw. We don't have hidden fees, and we don't upsell services you don't need. We stock common parts like contactors and capacitors on our trucks specifically to keep your repair costs down by avoiding multiple trips.
Scheduling Service Around Your Business Needs
We know that your business hours are precious. We work with you to schedule repairs at a time that causes the least disruption to your customers and employees. If you have a commercial emergency, call us at (323) 970-3113. We answer emergency calls within 30 minutes to get the process moving.
For properties with gated access or complex security, we coordinate with your property manager or site contact to ensure we have the necessary clearance. We respect your space and your time, aiming for efficient, professional service that gets your cooling back online as quickly as possible.
Mistakes That Lead to Costly Repairs
The biggest mistake I see in commercial HVAC is ignoring routine maintenance. When you wait for the system to stop cooling before you call for service, you're often dealing with a cascade of failures. A dirty filter that isn't changed on time can freeze the coil, which can then lead to compressor damage. It’s much cheaper to replace a filter than it is to replace a compressor.
Another common error is trying to 'top off' refrigerant without finding the leak. Refrigerant is a closed loop; if it's low, there is a leak. Adding more gas without fixing the hole is just throwing money away and can lead to more serious equipment damage down the line.
Safety First in Commercial HVAC
Safety is non-negotiable, especially when working on commercial rooftops. Our technicians are EPA-certified and trained to handle high-voltage electrical systems and pressurized refrigerant lines safely. We follow all manufacturer guidelines to ensure that your equipment is not only cooling properly but also operating safely for your staff and customers.
We also pay attention to the environment around the unit. In Tujunga, this means ensuring that electrical disconnects are protected from the elements and that the unit is properly secured. We leave your site clean and ensure that all safety panels are replaced and secured before we leave.
Making the Right Choice for Your Commercial AC
When your commercial AC fails, take a deep breath and check the basics: is the thermostat set correctly? Is the breaker tripped? If those aren't the issue, turn the system off to prevent further damage and call us. We will come out, diagnose the specific component that failed, and give you a clear, written price for the repair.
If the repair is minor, we will fix it on the spot. If the system is nearing the end of its life, we will tell you honestly so you can plan for a replacement rather than wasting money on recurring repairs. Our goal is to be the partner you trust for all your HVAC needs in Tujunga.

What Tujunga customers say about commercial ac repair
Verified reviews from homeowners in Tujunga and nearby neighborhoods who used our commercial ac repair 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.”
