What is Commercial HVAC Repair?

Commercial HVAC repair involves identifying the root cause and correcting problems within Heating, Ventilation, and Air Conditioning systems specifically designed for commercial properties.

This makes specialized knowledge crucial for effectively handling repairs that are beyond routine maintenance tasks.

Emergency A/C Replacement

One of our clients, a multinational high-end chain of hospitality enterprises, faced an urgent issue last summer. Despite attempts by multiple companies to repair their 12.5-ton A/C system, which had been in use for 35 years, none were successful. Realizing the futility of further repairs, they reached out to us for assistance. Upon arrival, we conducted a comprehensive diagnostic assessment of the system. Subsequently, we performed a thorough overhaul and maintenance of the condensing unit and evaporator, installed new seals on all cabinets, adjusted the blower fan speed, and rectified several leaks that had been poorly repaired by a previous company. Additionally, we swiftly addressed any other issues encountered. Remarkably, we managed to complete all necessary work and have the system operational again within a single business day. Satisfied with the results of our intervention, our client decided against replacing the unit, acknowledging it as one of their most effective cooling systems presently in operation.

Ventilation Repair in Los Angeles, Surrounding Areas & Coachella Valley

Repairing your ventilation system is crucial for maintaining a safe, comfortable, and efficient environment in commercial buildings. Just as regular maintenance is important, addressing and fixing issues promptly ensures that ventilation systems continue to function optimally and meet the demands of your business effectively.

Ventilation System Repair Essentials

Repairs to ventilation systems in commercial settings are necessary to address specific issues that can significantly impact air quality and system efficiency:

  • Air Quality:

    Repairs may be needed when systems fail to prevent the buildup of pollutants, bacteria, and viruses. This is especially critical in densely populated or high-traffic areas.

  • Temperature / Humidity Control:

    Issues with the Ductwork or Ventilation Systems result in a system that is unable to control temperature, and humidity effectively, this often leads to uneven temperatures in the conditioned spaces, and makes it much more difficult for the HVAC System to maintain a comfortable environment.

  • Energy Efficiency:

    Addressing repairs in Ductwork and ventilation systems can significantly reduce the load on heating and cooling systems, leading to enhanced energy savings.

Ventilation System Repair Procedures

Our targeted repair process ensures your ventilation system returns to optimal operation:

  • System Diagnosis:

    We begin by inspecting ducts, fans, and other components to identify the source of any issues, such as blockages or mechanical failures.

  • Effective Solutions:

    After diagnosing the problems, we provide detailed repair plans, including cleaning, part replacement, or adjustments necessary to restore functionality.

  • Performance Restoration:

    Repairs are executed to bring systems back to their original efficiency and operational standards, ensuring spaces are conditioned uniformly and air quality is restored.

Addressing Common ventilation Repair Challenges

Repairing a commercial ventilation system involves overcoming unique challenges that may arise due to system age or design complexities:

  • Space Constraints:

    We implement solutions that accommodate the spatial limitations of older or uniquely designed buildings without extensive renovation.

  • System Integration:

    Our repairs are carefully planned to work seamlessly with existing HVAC systems, enhancing overall performance without disrupting ongoing operations.

  • Aesthetic Integrity:

    We ensure that all repairs maintain the aesthetic quality of the visible components, such as vents and ducts, ensuring they remain both functional and integrated with the building’s design.

Transforming Air Quality for a Multinational Coffee Chain

Here is a perfect example of how, as a company, you must understand air ventilation as a fluid. This unit was installed by a contractor, passed city inspection, HERS rater testing (a third-party testing agency to verify installation), and also passed commissioning. This unit passed four different entities, and many other companies also worked on and maintained this specific unit. However, this coffee chain location struggled to cool down during summer, and excessive dirt would build up inside the location. Upon our testing, we found that the unit was somewhat operating within manufacturer specifications, but proper cooling and poor air quality were still problems for them. We found a problem with the air pressure between the A/C and ductwork. Upon lifting the unit up, we found that it was a really bad installation. Despite passing four different entities, we provided a few repair options. The client needed the unit up and running as soon as possible. It went from bringing in insulation particles from the attic, unconditioned outside air with dirt, and losing 65% of air to being sealed up, not bringing outside air in, and delivering a full capacity of 97%.

I run a restaurant, bakery and deli. We have 3 large walk in refrigerators, 2 freezers and about 10 other refrigerated units. It’s a big operation and I have used several companies over the years. I came across American Cool Heat & commercial refrigeration about 4 years ago. They are the most thorough and honest company I have worked with in 19 years of operation. I love that they warranty their work and explain everything to me. The owner, William, had me go on the roof with him to check out our refrigeration rack and explain each part, I made videos for reference. Our equipment was out dated and needed to be serviced. He showed me several areas where poor work had been done by other companies. His techs are friendly, efficient and professionally trained, I never have to guess or ask questions, they always clearly explain everything to me and give me some options depending on the job. They are replacing a defrost timer and condensing fan in my walk in freezer today. Whenever I call for service, they come the same day- even emergencies on weekends. Can’t say enough good things about this company. Ask for William!

We have a large business in Palm Springs. William and his team came highly recommended. From day one, they did the impossible. This includes rebuilding a 20-ton HVAC unit on our roof that was written off by other companies. Competitors wanted to remove it which included a crane, insurances, and of course the replacement cost. William, Frank, and the team assessed the unit, and gave us a 90% success rate on a repair vs. a replacement. They succeeded. From then on, they’ve handled all or our equipment… on time, up front, and always professional.
