When it’s time to replace your rooftop HVAC unit (RTUs), there are many factors to consider beyond the type of equipment you need.

Watch this short video to understand how our team of engineers and technicians ensure your building’s roof has the structural integrity to handle the load of your commercial HVAC unit.

Reinforcements, such as additional bracing, joists, protective mats, anchors, and vibration isolation, can be necessary to prevent damage. In addition, it is crucial to properly seal ductwork and electrical wiring to prevent water leaks.

Campbell, Inc. is your commercial mechanical contractor for all your rooftop unit installation and service needs.

To prepare for the reduction of hydrofluorocarbon (HFC) refrigerants for commercial HVAC systems, it’s essential to understand the Environmental Protection Agency’s (EPA) phaseout schedule which aims to decrease HFC production and consumption to 15% of baseline levels by 2036.

This initiative, under the American Innovation and Manufacturing (AIM) Act of 2020, addresses the high global warming potential (GWP) of HFCs, which are commonly used in air conditioning and industrial refrigeration systems. The phasedown is structured to gradually limit HFC availability, encouraging the transition to more environmentally friendly alternatives.

As your commercial mechanical contractor, Campbell will work with you to proactively assess your current HVAC and refrigeration equipment. We will determine the type of refrigerants in use and explore options for retrofitting or replacing systems with those that are compatible with low-GWP refrigerants, such as A2L refrigerants.

Trust us to facilitate compliance with regulations, optimize energy efficiency, and minimize environmental impact during this transition.

For more information on HFC refrigerants reduction check out our HVAC and A2L page.

The refrigerant industry is undergoing significant changes due to the phaseout of R-410A.

In this video we explain how the phaseout is part of efforts tied to the Montreal Protocol, aimed at reducing ozone-depleting substances and lowering the Global Warming Potential (GWP) of refrigerants to below 300.

R-410A was introduced as a replacement for R-22, which had a much higher GWP, but now R-410A itself is being phased out due to its GWP of 466.

Reduction targets are:

• By 2024 – R-410A usage must decrease by 60% or more
• By 2029 – A further reduction to 30% or less
• By 2035 – Complete phaseout, requiring a GWP below 300.

R-454B is the current refrigerant of choice to meet these standards because it is a lower-GWP alternative.

Campbell Mechanical Services is your industrial refrigeration systems expert to navigate these changes for both refrigerants and equipment!

Proper humidity control in commercial and industrial buildings is critical for maintaining indoor air quality (IAQ) and protecting the health of employees and customers.

Relative humidity (RH) levels between 40-60% are ideal for inhibiting the growth of mold, bacteria, and dust mites, which thrive in high humidity conditions and can trigger respiratory issues or allergic reactions. Conversely, low humidity can cause the air to become excessively dry, leading to skin irritation, dehydration, and increased transmission of airborne viruses.

An optimized commercial HVAC system with advanced humidification and dehumidification controls maintains consistent RH levels, preventing these health risks while enhancing occupant comfort. Additionally, systems equipped with sensors and energy-efficient dehumidification technologies can adapt to fluctuating conditions, ensuring precise control and minimizing energy consumption.

Maintaining proper humidity levels is not just a comfort factor but a key component of a healthy, productive indoor environment. Watch our Campbell, Inc. one minute video that details how regulating relative humidity as well as humidity levels and percentages can ensure your commercial building is operating at its optimal level.

MERV filtration, when combined with needlepoint bipolar ionization technology, can improve indoor air quality by removing sub-micron particles in the air including dust, dander, viruses, and bacteria.

Traditionally, sub micron particles don’t have enough surface area to be moved through the commercial HVAC system to filtration. But needlepoint bipolar ionization technology solves this issue, capturing particles below one micron including viruses, bacteria, and particulate odors such as wildfire smoke.

Watch this three minute video to understand this revolutionary technology.

A properly fitted HVAC filter is vital to stopping mold spores and dust particles in the air and improving air quality. Check out this video where we discuss the difference between a standard air filter and the MERV8 filter.

MERV 8 filters are a popular choice for commercial HVAC systems due to their efficiency, affordability, and compatibility with most standard systems. These filters are designed to capture particles between three to 10 microns in size, including dust, pollen, mold spores, and lint, making them suitable for facilities with moderate air quality requirements such as office buildings, retail spaces, and schools.

One of the key benefits of MERV 8 filters is their low resistance to airflow, which helps maintain energy efficiency and reduces strain on commercial HVAC systems. This makes them a cost-effective option for businesses looking to protect equipment and ensure reliable air circulation without significantly increasing operational costs.
