Commercial buildings in Los Angeles work hard, and so do their HVAC systems. Intense summer heat, strict local codes, and nonstop occupancy demands mean your equipment needs partners who truly understand the territory. At Air-Tro, we have been that partner since 1969 – family-owned, fourth-generation, and 100% focused on commercial and industrial solutions across Los Angeles, Pasadena, and the San Gabriel Valley.

Whether you are facing an unexpected breakdown or simply want to protect your investment, our team delivers straightforward answers, fast response times, and lasting results. If your building feels too warm, too humid, or your energy bills keep climbing, reach out today for a no-obligation assessment – we are ready when you are.

Choosing the Right Commercial HVAC Contractor in Los Angeles

Not every contractor is equipped for commercial work. You need a team that specializes in large-scale systems, knows Title 24 inside and out, and shows up prepared. Look for licensed, insured professionals with NATE and EPA certifications who provide clear written estimates and realistic timelines from the first conversation.

At Air-Tro we check every box and then some. Our technicians arrive with fully stocked trucks and decades of local experience, so we solve problems correctly the first time instead of returning for callbacks.

Commercial HVAC Repair Los Angeles: Recognizing the Warning Signs

Frequent cycling, uneven temperatures between floors, strange noises from the mechanical room, or sudden spikes in utility costs are all red flags. In our climate, coils and condensers accumulate dust and wear faster than most people realize. Minor issues left unchecked quickly become major disruptions.

Our repair process starts with a detailed diagnostic using the latest tools, followed by precise fixes – whether that means replacing a failed sensor, addressing a refrigerant leak, or upgrading older components. We handle everything from standard rooftop units to complex VRF and VFD systems. If any of these symptoms sound familiar in your facility, contact us right away for fast, honest guidance.

Commercial Heating Repair Pasadena: Local Expertise Where You Need It

Pasadena properties – from retail corridors to office suites and light industrial spaces – face their own mix of heating and cooling demands. Milder winters still require reliable performance, especially in buildings with older infrastructure or high occupancy. Our technicians know the specific challenges of the San Gabriel Valley and arrive equipped to restore comfort quickly.

Commercial HVAC Installation and System Upgrades

When repair is no longer the best long-term answer, we guide you through smart replacement or upgrade options that meet current energy codes and deliver measurable savings. We work with every major brand and configuration, from compact ductless splits to large-scale chillers, generators, centrifugals, and cooling towers – exactly the equipment you find throughout Los Angeles commercial and industrial sites.

How Often Should Commercial HVAC Be Serviced?

The industry standard is professional service at least twice a year – once in spring and once in fall – to prepare systems for peak seasons and catch small issues before they grow. In Los Angeles, where cooling loads run heavy for many months, many facilities benefit from quarterly visits. Consistent preventative maintenance following ASHRAE guidelines maintains comfort, improves indoor air quality, and reduces energy consumption. Our customized plans make scheduling effortless and keep your equipment running at peak efficiency.

If you have not had a professional inspection in the past year, now is the perfect time to schedule one.

Why Los Angeles-Area Businesses Trust Air-Tro

We are proud to be a local, family-owned company in our fourth generation. President Bob Helbing and our team of 25 EPA-certified technicians – most also NATE-certified – live and work in the communities we serve. We carry a full range of refrigerants on every truck and maintain strong relationships with manufacturers and distributors, which means parts are available when you need them.

Since the family founded the company in 1969, we have emphasized maintenance over emergency calls. It is far better to service equipment on your schedule than to scramble during a heat wave. That philosophy still guides everything we do.

Are you searching for commercial air conditioning in Los Angeles or a commercial heating contractor in Los Angeles? Look no further. I’m Bob Helbing, president of Air-Tro Heating and Air Conditioning. I am a fourth-generation contractor. My grandfather and great-grandfather also worked in contracting and construction. One thing commercial clients want is they want their headaches to go away. They want to know that when they call you, you’ll get out there, you’ll get to work, you’ll get the job done.

We have 25 service technicians – all EPA certified. Most of them have the NATE certificate as well, showing that they have expertise in working on heating and air conditioning systems.

We’ll take care of small ductless split systems all the way up to chillers, centrifugals, cooling towers, and any of the equipment that you’ll find in commercial and industrial locations. We’ve always made sure that commercial work has been at the heart of what we do. That means that we have to be familiar with a wide variety of systems.

We carry a whole family of different refrigerants on our trucks. Our technicians are trained and skilled in working in pretty much every type of equipment out there.

One thing that we have done since the beginning of the company when my dad started it back in 1969 is we have emphasized maintenance. You know it’s great to know that someone is there when you need them but it’s even better when your equipment is well taken care of so you don’t really need them at all. We come out there, we service the equipment, we do make a visual inspection, make sure all the parts and components are working in good form. That way things get taken care of when it’s convenient for you and not when it’s an emergency.

We have relationships with all the distributors. We have relationships with the manufacturers. That allows us to get what we need when you need it.

Award winning and family owned, we are committed to providing responsive, courteous service, cutting edge product knowledge and system expertise, and the most overall value to every one of our clients.
