4 Common Mistakes in Rooftop HVAC Unit Installation

The Importance of Protecting Your HVAC Investments With Quality Roof Curbs.

The installation of an HVAC system in any commercial building is a significant investment that needs to be approached with precision and attention to detail. Rooftop HVAC units, commonly found in commercial buildings across the nation, serve as the backbone of the building’s climate control but often face a multitude of external factors that can significantly affect their functionality. One crucial element in the installation of rooftop HVAC units that is often overlooked is the support structure of roof curbs.

A high-quality roof curb is vital in supporting the HVAC equipment and protecting the roof. Yet, despite its importance, there are other various common HVAC installation mistakes that are commonly made. Here is a highlight of these mistakes and the role of high-quality roof curbs in preserving the integrity of your HVAC unit and, ultimately, your building.

1.Inadequate Support and Mounting Issues

The first and most common mistake in rooftop HVAC unit installation is the underestimation of the importance of proper support and mounting. A poorly installed support system can lead to unit vibration and movement, causing premature wear and tear on the unit as well as potential damage to the roof structure.

Mounting errors can result from the non-compliance of mechanical fasteners with the unit’s specifications, which can lead to overloading and damage. In addition, insufficient support can cause the unit to tilt or lean, impacting its efficiency and safety.

The Role of High-Quality Roof Curbs

A high-quality roof curb acts as the foundation for your rooftop HVAC unit, providing a sturdy and level platform that is customized to fit the specific make and model of your unit. Roof curbs prevent the concentration of weight on weak spots of the roof and evenly distribute the load, safeguarding against structural damage.

2.Poor Positioning and Accessibility for Maintenance

Another mistake commonly made is neglecting proper positioning of the HVAC unit for maintenance access. Placing the unit in an inaccessible location can lead to increased labor costs for maintenance and repairs, as well as potentially hazardous conditions for service technicians.

Inaccessible units may also lead to compromised air flow and inefficiencies in the heating and cooling process. This can result in increased energy consumption and reduced equipment lifespan.

The Role of High-Quality Roof Curbs

Custom-designed roof curbs account for the optimal positioning of the HVAC unit, allowing enough space around the equipment for easy access during maintenance. They also facilitate proper drainage to prevent standing water, which can damage the unit and promote mold growth.

3.Improper Sealing Leading to Energy Loss

Improper sealing also allows moisture to penetrate the building envelope, which can lead to costly water damage and create an environment conducive to mold and mildew growth.

The Role of High-Quality Roof Curbs

High-quality roof curbs are designed with integrated flashing and thermally broken construction that ensures airtight installation. This reduces the risk of air and water infiltration, maintaining the energy efficiency of the building and the indoor air quality.

4.Neglecting Local Building Codes and Regulations

Finally, many rooftop HVAC installations run afoul of local building codes and regulations. Compliance with these standards is not only legally required but also essential for the safety and functionality of the HVAC system and, ultimately, the building as a whole.

Neglecting building codes can lead to costly fines and, in the event of a system failure, the installation may be found at fault, voiding the building’s insurance in the process.

The Role of High-Quality Roof Curbs From Design Components, Inc.

High-quality roof curbs are often pre-engineered and certified to meet local building codes and standards. This ensures that the unit and its support structure are in full compliance right from the beginning, saving time and hassle during the installation process.

The installation of rooftop HVAC units is a complex and highly specialized endeavor that requires the utmost attention to detail. By avoiding the common mistakes listed here and prioritizing the use of high-quality roof curbs, building owners can ensure the long-term efficiency, safety, and integrity of their HVAC systems.

It is wise to work with experienced HVAC professionals such as Design Components, Inc., who understand the importance of every component involved, particularly the critical role that roof curbs play in the overall installation success.
