During the summer, HVAC (Heating, Ventilation, and Air Conditioning) systems are subjected to increased stress due to the extreme heat. Here are some factors that contribute to this stress: Higher Cooling Demands As temperatures rise, people rely more on air conditioning to maintain comfortable indoor environments. This increased demand for cooling puts a significant load on HVAC systems, causing them to work harder and for more extended periods. Temperature Differential HVAC systems operate by removing heat from indoor spaces and expelling it outside. In hot weather, the temperature difference between the indoor and outdoor environments is more significant, making it more challenging for the system to transfer heat efficiently. Continuous Operation HVAC systems often run continuously during hot summer months to maintain desired indoor temperatures. [...]
Theft of residential and commercial condensing units is on the rise. A hundred dollars’ worth of "scrap" copper could cost your organization thousands of dollars and a lot of inconvenience to replace your outdoor condensing units. The price of copper has more than doubled in the past few years and thieves are out to steal or gut condensing units wherever they can find them. Why are my Condenser Units a Target for Thieves? Valuable Components HVAC systems have components that can be stolen and sold for recycling or spare parts. Recycling companies and junk yards often buy copper coils from HVAC systems with no questions asked. HVAC Units are Usually Located in Isolated Areas of Your Property External HVAC units are typically located outside of [...]
Effective January 1, 2023 VASEY works with a variety of industry-leading HVAC manufacturers. As 2022 draws closer to its end, we are receiving regular updates about the new 2023 Department of Energy’s (DOE) new minimum efficiency standards for commercial packaged HVAC requirements. Why is this Occurring? These changes are a part of DOE’s ongoing efforts to reduce the United States’ energy consumption. ALL HVAC manufacturers will be required to comply with the new testing procedures and standards. While complexities exist during this transition, VASEY is here to help you navigate them smoothly. Every six years the Department of Energy (DOE) reanalyzes the effects of energy usage, sets minimum efficiency requirements and manages the testing standards by which those efficiencies are measured. In 2018 the [...]
The Department of Energy (DOE) in response to the climate crisis has increased the minimum Annual Fuel Utilization Efficiency (AFUE) standard from 80% to 90% for all new heating and cooling units to move America closer to net-zero carbon emissions by 2050.1 For example, a high-efficiency gas furnace with an AFUE of 97 percent creates 97 BTUs of heat with every 100 BTUs of gas it uses. The rest is typically lost to the outdoors and flue emissions. A higher AFUE means greater efficiency. The DOE sets the minimum efficiency standards for ALL heating and cooling equipment manufacturers. Currently, it is 80 percent. Effective January 1, 2023, the new minimum efficiency will be 90 percent. What does that mean to you? Typically, the more efficient [...]
INDIANAPOLIS — Sycamore School in Indianapolis is updating its air filtration system to keep students and staff safe. The private school on the north side reopened August 13 with in-person instruction only. The new air system cost the school about $40,000 and will "clean the air of SARS, which includes COVID, also cold and flu viruses, dust and mold," according to the Head of School Diane Borgmann. Complete air exchange is supposed to occur every 10 minutes. The school will also implement extra cleaning, install automatic faucets and soap dispensers in bathrooms, and provide plexiglass for in-between students when they have to work in groups. As of now, Sycamore School is not offering simultaneous virtual classes as an option for students. "That’s not to say [...]
By installing a Bipolar Ionization (BI) or Ultraviolet Light Germicidal Irradiation (UVGI) system within your HVAC system, you can reduce or even eliminate airborne particles such as bacteria, virus cells, mold, allergens, odors, and volatile organic compounds (VOCs). What is Bipolar Ionization (BI) Technology? Bipolar Ionization technology produces a natural bio-climate rich in positive and negative ions much like sunlight does in the atmosphere. The negative ions contain an extra electron while the positive ions are missing an electron resulting in an unstable condition. To re-stabilize, these bipolar ions seek out atoms and molecules in the air to trade electrons with, effectively neutralizing particulate matter, bacteria and virus cells, odorous gases and aerosols, and VOCs. What is Ultraviolet Germicidal Irradiation (UVGI)? As radiation, Ultraviolet (UV) [...]
It’s a FACT! Our technician traveled to a nearby church — the before, a draft inducer, barely held together by spittle, rust, and dirt. The draft inducer is designed specifically to ensure that combustion gases are vented properly out of the furnace to the outside. We called the manufacturer. The lead time to order and ship a new fan – a whopping EIGHT weeks!! That means, the church would be affected in the months of October through December – without proper air circulation. We all know how fickle Mother Nature can be in Indiana. We weren’t satisfied with status quo. Our solution? We built a new fan 100% from scratch and the system was up and running in a week. At VASEY, we have [...]
Toyota Industrial Equipment has been a VASEY service and project customer since 2011. The Toyota’s server room cooling system connected to production ceased operation. Consequently, the server was overheating. If left unattended the server would crash and production would come to a halt. VASEY received an emergency service call in the middle of the night. With VASEY’s 24/7/365 service operation and highly skilled technicians, the server room cooling system was repaired with no adverse effect to production. By the next morning, VASEY had the cooling system up and running. More importantly, manufacturing and production kept running without any interruptions.
