YORK, Pa. – March, 2013 – United CoolAir Corporation (UCA) is repositioning itself to stand out in the high-growth retrofit air conditioning marketplace by adding the new tagline “All-Indoor Solutions,” which calls specific attention to the fact that all UCA equipment mounts entirely indoors, requiring no roof or pad space. UCA manufactures a wide range of equipment styles for practically any retrofit application. With the aging of many buildings, especially in urban areas, older systems need replacement by more capable units that meet the new efficiency standards. Many of these old units were installed at the time of the building’s construction, making them difficult to replace. “A high proportion of the multi-story buildings in cities like New York City, Boston and Chicago have floor-by-floor air conditioning systems that are difficult to access. The problem is not getting the old system out but rather getting the replacement system in at a reasonable cost. In most metropolitan buildings, there is no available space for exterior condensing or rooftop unit mounting,” said Neil Tucker, President of United CoolAir. Tucker remarked that often owners, contractors, and even some consulting engineers tend to focus on equipment cost rather than the Total Installed Cost. When you include the additional charges for special permits, crane rental, rigging, building modifications, equipment modifications and the labor to make these changes, the new HVAC equipment cost can be a small fraction of the entire project.
UCA’s All-Indoor Solutions include unique characteristics separating them from other suppliers of retrofit cooling equipment. Please see a list of the characteristics below.
- UCA offers a variety of equipment styles and sizes that are tailored to fit practically any building requirement. UCA equipment is designed to be adapted to the most difficult installations and at a lower installed cost.
- Configurations include horizontal, vertical, ceiling grid, VAV and even dedicated outside air systems.
- Air conditioners mount entirely indoors requiring no rooftop space, slab or special exterior condensing section mounting. Units are available in air-cooled, water-cooled, chilled water and heat pump configurations.
- The equipment is modularly designed, allowing it to be disassembled for transportation. Most sections fit through standard doorways and elevators, eliminating the need for expensive building modifications, rigging or crane rental.
- The equipment retains the exterior architectural appearance of the building, especially with historical structures.
- Theft and vandalism is practically eliminated without the added expense for special security systems or cages.
- Equipment is factory refrigerant charged. There is no piping, brazing, evacuation, or refrigerant charging in the field which means a lower installed cost.
- Systems are made to order allowing us to place air paths, electrical connections and refrigerant lines that match up with the existing hookups. Contractors can completely install a number of our systems in as little as a weekend, minimizing workplace disruption.
- UCA equipment maximizes indoor space by taking advantage of closets, small rooms and ceiling spaces. The equipment is protected from harsh outdoor weather extending its operating life, and high maintenance fees are eliminated for outdoor servicing.
- UCA uses standardized parts and components allowing routine maintenance to be completed very cost effectively.

HEALTHCARE AIR CONDITIONER REPLACEMENT TURNS INTO SIMPLE OPERATION
New York City is certainly renowned for the quantity and variety of tall buildings towering over the Manhattan skyline. Many of these structures are at a point where age has taken its toll on mechanical systems and now require replacement. Even if they are still operational, today’s new air conditioning systems are more energy efficient, making it cost effective for change-out.
You might not think this is a big deal beause it’s done every day but New York City, like many large metropolitan areas, is a little bit different from a smaller city like say White Plains, NY where mechanical systems are generally easier to access. In New York City, replacing a large system often requires demolition, cranes, rigging and a lot of extra work.
We were hired for a project at an EmblemHealth facility located in mid Manhattan around 35th and 7th avenue. The building was erected in the early 1970’s and the mechanical systems have been running for over 25 years. Since it is a hospital, maintaining ideal comfort conditions is critical. The air conditioning system had to be replaced quickly and with the least amount of disruption to the patients, service providers and staff. Like many tall buildings, space conditioning is done floor by floor rather than large central units. Many of the systems were installed during the building construction where access was not an issue. Removing the old systems is generally not a problem because the units are disassemble by whatever means available and scrapped. Getting the new units to their installation location is where the fun begins.
The EmblemHealth building had four existing units spread out from the basement, main floor and at an upper level. Sizes ranged to 45 tons and the replacement units would be the same size. MWSK Equipment is a manufacturer’s rep located on 7th Avenue in lower Manhattan. They service the five boroughs and have had a lot of experience in squeezing air conditioning systems into tall structures.
“Often the HVAC contractor has to do a lot of preparation work in order to fit an A/C system through small passageways. Larger units may have to be raised by crane to upper floors and require rigging, permits and building modification. If they take it through the building, the unit may have to be delivered partially disassemble and reassembled on site, or walls and doorways opened to allow access,”said Freddie Taruc, Sales Manager at MWSK. Regardless of the entry method, the installation cost can easily exceed the unit’s cost when you measure man hours and special equipment necessary to complete the job. And of course there’s the additional time needed for demolition, installation and final repairs.
Taruc said they needed to get the replacement units in quickly and with as little building modification as possible. They naturally selected their best candidate for the job—United CoolAir. “United CoolAir makes cooling equipment uniquely designed for our market. They manufacture a class of air conditioners with many flexible features that not only allow negotiation through narrow doorways and halls but also require no evacuation and charging after installation,” said Taruc. Tareq Batarseh, PE, LEED AP Associate for Robert Derector Associates Consulting Engineers (RDA) is the specifying engineer for the latest EmblemHealth project and is no stranger to these kinds of retrofit installations. “Each room has its challenges, some rooms have height restrictions and width restrictions,” said Batarseh. “United CoolAir units have the ability to connect to existing piping and ductwork with minimal modifications”. He likes the flexibility in United CoolAir’s system design and their ability to modify the cabinet sizes as needed, two major reasons why they are an approved manufacturer for EmblemHealth.
Unlike most commercial buildings, Healthcare facilities are generally active 24 hours each day. The retrofit was scheduled for two weekends with two units replaced each weekend. John McBride, Design Engineer for JFK & M Consulting Group made sure the replacement work would not interrupt the facility’s busy weekend schedule.“The old equipment was removed on a Friday and the replacement units were brought in with minimal interference with the hospital’s operations. The modular sections were quickly reassembled and connected to the existing hookups. Since the units were pre-charged at the factory, brazing, evacuation and charging in the field were eliminated saving many hours of valuable labor. The units were operational by Monday morning at the start of the new week,” said McBride. This latest installation went smoothly much to the credit of the easily-handling modular units, resealable refrigerant connections and factory charged sections. This came as no surprise to Joe Ptak, Chief Building Engineer for EmblemHealth, who was first introduced to United CoolAir air conditioning systems. They installed the first units in his building and have not looked back since. “I was very pleased with the performance of their units then and I recommended using United CoolAir systems for all the other EmblemHealth mechanical system replacements,” said Ptak. He said they have other facilities ready for the same treatment in the near future.
United CoolAir introduced the latest portable unit available under the Therm-Air brand name. This unit is a horizontal portable 5-ton unit that is only 29.5″ wide. This unit can be operated indoors or outside. The narrow PACH5 model is available as a cooling only, cooling with electric heat, straight heat pump or heat pump with auxiliary electric heat configuration. These configurations are enhanced with available options such as the electric heat, a remote thermostat or a condensate pump. Other options are available. The unit has been designed around the tough rental duty requirements that United CoolAir units are known for. This unit will provide many years of performance and thus provide you with an excellent ROI. The unit employs a powder coated, heavy duty steel cabinet sitting on swivel / lockable casters along with a single scroll compressor. The unit comes factory charged with an environmentally friendly refrigerant. The removable duct collars are 14″ (one supply, one return). For use indoors there is a 14″ ductable condenser discharge available. Standard power connection would be with color coded CamLock connections. The control panel requires a tool to gain access.
As with all Therm-Air units, the features and options can be tailored to meet your specific requirements. Contact the factory at 717-843-4311 for details and pricing.
United CoolAir is please to announce the availability of the EZ-Fit variable air volume (VAV) systems. These are modular floor-by-floor systems specifically targeted for the renovation and replacement markets.
EZ-Fit modules are 10 through 15 tons or 20 through 25 tons. Each module is shipped in three sections. The sections will fit through standard 3-0 doors, into most elevators and down narrow hallways with tight corners. This means that building alterations or modifications are not required to get the unit into the mechanical room.
The modules are shipped with a factory refrigerant charge. There is no need for brazing, evacuation or field charging. Projects can be completed quicker with less disruption to tenants.
Modules can be “ganged” together to get systems up to 100+ tons. Several configurations of units are possible.
Units are available as water-cooled or water source heat pumps self contained units. Air-cooled is available with a remote condenser. Water-Cooled and air-cooled units can be constant air volume or variable air volume. The water source heat pumps are available as constant air volume models.
As with other United CoolAir products, a wide variety of options allow the units to be tailored for your specific application requirements. A plenum fan or Parallel Fan System can be selected in lieu of the standard DWDI belt drive blower. A digital scroll compressor can be included for excellent part load operation.
The unit features and modular construction provide low installed cost advantages.
