With more than 15 years of experience in mechanical engineering, Avi Polischuk received his degree from George Washington University in 2000. A few years later, Avi Polischuk became an owner of the commercial building design firm R&S United Services.
R&S has established itself as the only firm in New York City that is entirely self-performing, which means it does not employ subcontractors. The business also serves as one of the city’s primary developers of high-quality HVAC systems, designing for high-rise condominiums, hotels, and commercial buildings.
HVAC means heating, ventilation, and air-conditioning, a combined system that is common in most modern buildings. Traditionally, HVAC systems have not been energy efficient, but recent advances in technology have improved cost-effectiveness and minimized the ecological footprint of HVAC units.
The efficiency of individual HVAC systems is monitored and rated by the Seasonal Energy Efficiency Ratio (SEER). The higher the SEER rating, up to 23, the more efficient the unit. In 1992, the US government updated the minimum efficiency rating for future HVAC systems from 6 to 10. In 2006, this minimum was increased again, to 13.
Systems that receive superior ratings (performing within the top 25 percent) can be identified by the recognizable Energy Star label, and offer as much as twice the efficiency. R&S United Services is dedicated to upholding these high standards in energy efficiency.
As the owner and CEO of R&S United Services, Avi Polischuk provides comprehensive HVAC engineering designs and solutions for New York metro construction projects. With a degree in mechanical engineering from The George Washington University, Avi Polischuk works with developers on HVAC design projects, which require the specialized skills of pipe fitters.
A pipe fitter, or steamfitter, assembles and installs mechanical pipe systems to transport the steam, hot water, air, chemicals, or gas necessary in buildings and industrial processing systems. Pipe fitters coordinate with project managers to create and configure appropriate pipe system layouts. Their subsequent responsibilities include ordering the pipes, supports, hangers, hydraulic cylinders, and other materials necessary for the job.
Steamfitters must know how to manipulate pipes by torch cutting, sawing, welding, and hammering in order to customize pipes for a project. Safe installation procedures are critical, and pipe fitters must be able to select proper clamps, brackets, and equipment to secure pipes to walls and fixtures. Problem solving skills are important in steamfitting in order to resolve issues that may occur during a job, including leaks, cracks, obstruction issues, or erosion within the system. When a project is complete, steamfitters repair and maintain the pipe systems.
A longtime specialist in the engineering of high-rise buildings, Avi Polischuk has overseen numerous construction projects as owner and president of R&S United Services in Amityville, New York. Under the leadership of Avi Polischuk, the company offers a number of services, such as the maintenance of heating, ventilating, and air-conditioning (HVAC) units in both residential and commercial properties.
In order to prevent future issues with your HVAC unit, it is important that you or an HVAC company conduct system maintenance throughout the year. Doing so will not only help increase the efficiency of your unit but will also lengthen its operational life. In general, you should examine your HVAC unit every month, checking the refrigerant lines and replacing the old air filter with a new one, though you may need to change filters more frequently if you own pets. On a weekly basis, you should clear any debris, including grass clippings and leaves, from any outside HVAC unit.
In addition, you should complete more in-depth annual maintenance on your HVAC unit. For example, you need to inspect the evaporator coils to ensure that no mold has grown. Most systems also have condenser coils that collect dirt and deteriorate as a result, thus decreasing their performance. When conducting maintenance, you should replace these parts as needed to ensure maximum efficiency.
A George Washington University alumnus, Avi Polischuk owns and operates R&S United Services, based in Amityville, New York. Under the leadership of Avi Polischuk, the company focuses on bringing the highest level of energy efficiency to high-rise construction projects; in particular, through the use of sophisticated heating, ventilating, and air conditioning (HVAC) systems.
In 2013, residential and commercial buildings were responsible for 40 percent of the United States’ total energy consumption. On average, 21 percent of such energy use is strictly for cooling and heating residential buildings, such as condominiums. A building owner, depending on preference, has several HVAC options for reducing energy expenses, including the following:
1. Water-cooled VRV, also known as VRV-WIII, utilizes minimal energy to control different zones within an infrastructure and accommodates both open floor plans and cellular applications. Composed of unified condensing units, the VRV-WIII system has the ability to recover energy through a water-loop application. It is an energy-efficient alternative to traditional water-source heat pumps or infrastructures requiring a water-cooled chiller.
2. An evaporative pre-cooling system leverages adiabatic cooling to lower temperatures by as much as 30 percent. Working in conjunction with air-cooled chillers, the system decreases electricity use by reducing the temperature of the air surrounding the unit. As a result, the refrigerant cycle works more effectively and more heat can be released.
3. A variety of geothermal heat pumps are rated by Energy Star as the most efficient pumps in the market. Among the energy-efficient models are the American Standard A1GX Series with Premier Control, the ClimateMaster Tranquility 30 (TE) Series with iGate Controls, and the GeoStar Sycamore Series with Aurora Control, all of which offer variable-speed options that improve indoor comfort and save on electrical expenses.
A member of the Mechanical Contractors Association, Avi Polischuk joined R&S United Services in 2000. Through his New York company, Avi Polischuk offers expertise and services in designing energy efficiency into high-rise construction projects.
According to the U.S. Department of Energy, commercial and industrial buildings in the United States use more than $400 billion of energy each year, accounting for half of all total U.S. energy use. In terms of heating, ventilation, and air conditioning (HVAC), high-rise buildings consume more energy than small-unit commercial real estate because they require HVAC systems to service greater number of floors, and if applicable, different zones of buildings.
To reduce energy consumption and increase efficiency in commercial and high-rise residential facilities, the Department of Energy funded a project conducted by the US-India Joint Center for Building Energy Research and Development, which seeks to enhance HVAC systems with the integration of additional technology and an outdoor non-compressor air system.
The project commenced in 2012 and has funding through 2017. By the end of the project term, the organization hopes to provide solutions that improve HVAC physical systems, optimizes cooling and dehumidification systems, and increases system performance by 30 percent.
Avi Polischuk, a member of the Mechanical Contractors Association of America and the Building Trades Association, possesses 15 years of experience in the construction and real estate development field. Currently, Avi Polischuk owns and operates R&S United Services, a company that integrates energy-efficient heating, ventilating, and air conditioning (HVAC) systems into New York City high-rises.
Among the many solutions for making HVAC systems more energy efficient is the use of adiabatic cooling, which is widely used by New York engineers in the construction of residential high-rises. This process, used in evaporative pre-cooling systems, has the ability to lower air temperatures by as much as 30 percent. As a result, the amount of energy consumption also decreases.
Most efficient in warmer surroundings, adiabatic cooling employs wetted media to drop air temperature. Hot, dry airstreams flow across wetted media and in return, exchange 90 percent of the sensible heat for latent heat and increase relative air humidity. Once released, the chilled air creates a cooler environment.
