Suburban Hospital Air Handler Restoration Saves Capital

Hospital air handler restoration saves capital budgets for Tampa Bay healthcare facility! This project profile examines how HVAC restoration saves time, money and energy compared to replacing aging equipment. Let's jump in! The Challenge: A large suburban hospital located in Tampa Bay with a 479-bed facility offers comprehensive healthcare services for the region. Recently, SiteLogIQ was working with the hospital on energy/performance surveys to improve facility operations. During the study two air handler units serving Labor and Delivery rooms in The Women’s Center, The Baby Suites were identified as candidates for replacement due to degraded conditions and performance. The Solution: Due to the units’ location inside the penthouse and replacement costs, including time and facility disruption, it was determined that hospital air handler restoration could be done with WTI | Pure Air Control Services HVAC New Life program. Hospital Air Handler Restoration with HVAC New Life HVAC New Life is a series of component services conducted over consecutive nights. These phased services effectively cleans, refinishes, and restores performance to an AHU without loss of supply air during ...

Not All Air Handler Renewal is The Same

Air handler renewal or HVAC restoration is a popular service that refurbishes aging equipment. In fact, this service costs significantly less than HVAC replacement and is done in far less time. So, it frees capital budgets for more critical expenditures and minimizes disruption to facility operations. However, not all air handler renewal is the same. Facility managers and building owners with large inventories of chilled water air handler units (AHUs) understand the challenges of keeping the equipment maintained for optimal ventilation and air quality. Often, it’s hard to keep up. Especially with large campuses like in healthcare, education, and manufacturing. Plus, choosing the right companies or single company to partner with presents unique challenges, too! Air Handler Renewal: One Goal, Many Factors AHUs are sophisticated pieces of mechanical equipment. They are situated in the middle of a chilled water loop between the chiller, pumps, and cooling tower. AHU restoration needs vary depending on their size, age, and the type of building they are in. In other words, there is no one size fits all process to air ...

Enhancing Indoor Air Quality in Schools with HVAC Solutions

Ensuring a healthy learning environment is crucial for the well-being of students and staff in any K-12 school system. One key aspect often overlooked is indoor air quality (IAQ), which directly impacts the health, focus, and productivity of everyone within the school community. In this blog article, we will explore the recommendations provided by the U.S. Environmental Protection Agency (EPA) for improving indoor air quality in schools, with a specific focus on the indispensable role Heating, Ventilation, and Air Conditioning (HVAC) systems play in achieving these goals. Importance of Indoor Air Quality in Schools Indoor air quality significantly influences the health and well-being of students and staff. Poor IAQ can lead to respiratory issues, allergies, and even affect cognitive function. The EPA emphasizes the need for schools to prioritize IAQ to create a conducive learning environment. EPA's Recommendations The U.S. EPA provides comprehensive guidelines for schools to enhance indoor air quality. These recommendations include regular maintenance of HVAC systems, proper ventilation, use of air purifiers, and monitoring of indoor pollutant levels. These measures collectively contribute to a ...

Dirty Cooling Coils in Air Handler Units – 3 Main Culprits

In the world of facility management, maintaining the optimal performance of air handler units is crucial. One key aspect that often gets overlooked is the cleanliness of cooling coils. Dirty cooling coils can lead to reduced efficiency, increased energy consumption, and compromised indoor air quality. In this article, we'll explore three main ways cooling coils in air handler units get dirty and discuss effective solutions, with a focus on high-temperature, low-pressure steam cleaning. The Three Main Culprits of Dirty Cooling Coils
  1. Filter Bypass: One of the primary culprits behind dirty cooling coils is filter bypass. Air filters are designed to trap dust, debris, and other contaminants, preventing them from entering the air handler unit. However, when filters are improperly installed or damaged, particles can bypass the filter and accumulate on the cooling coils. This not only hampers the unit's efficiency but also poses a threat to the overall system.

  2. Cabinet Infiltration: Another common cause of dirty cooling coils is cabinet infiltration. Air handler units are housed in cabinets to protect them from external elements. However, if ...

HVAC Energy Consumption in Commercial Buildings

In the dynamic world of facility management, optimizing energy consumption is paramount for both environmental sustainability and cost-effectiveness. HVAC systems play a pivotal role in maintaining comfortable environments. However, their energy usage can vary significantly based on geographic locations in the United States. In this article, we delve into the nuances of HVAC energy consumption in commercial buildings and explore the impact of aged equipment and obstructed coils on overall efficiency. Additionally, we provide actionable recommendations for assessing and maintaining air handler units. HVAC Energy Consumption Across U.S. Regions Geography plays a pivotal role in determining HVAC energy consumption. The diverse climates across the U.S. result in distinct demands on HVAC systems. For instance, southern states with hot and humid climates may rely more on air conditioning, while northern states might prioritize heating during colder seasons. Understanding these regional nuances is crucial for effective energy management. Impact of Aging HVAC Equipment Older HVAC equipment poses a significant challenge to energy efficiency. Outdated systems often lack the technological advancements present in newer models, leading to increased energy consumption ...
