Our Energy Experts can analyze your facility's needs and recommend the best-matched and most cost-effective HVAC solutions. Packaged HVAC systems consist of pre-assembled, off-the-shelf equipment that provides space heating, cooling, and ventilation. A wide range of configurations are available, including both traditional and heat pump systems. Packaged systems typically fall into three general categories: Multiple packaged HVAC units are usually required to serve an entire building. This can be an advantage, since each system can be well matched to the interior space that it serves.

Packaged HVAC units are used in almost all classes of commercial buildings. However, in some situations, custom or semi-custom HVAC systems are a better solution due their higher capacities and, in some cases, even greater efficiency. A representative from our HVAC Consulting Team can determine which type is best for your facility. Packaged HVAC systems are especially suitable in situations where the absolute highest levels of performance are not required. In these situations, packaged HVAC systems offer several benefits over custom or semi-custom HVAC systems: Despite these many benefits, in some situations a custom or semi-custom HVAC system may provide a better solution. A representative from our HVAC Consulting Team can determine the type of system that can best serve your facility. Most manufactures of packaged HVAC systems offer useful options for their systems, some of which can be installed as retrofits to existing packaged systems. Some typical options include:

A representative from our HVAC Consulting Team can determine which of these options might be suitable for your facility. New technologies and methods are constantly arising that can further expand the benefits and applications of packaged HVAC systems. grand air ac unitWe maintain a staff of specialized professionals who constantly monitor trends and advances in both packaged HVAC systems and custom HVAC components. heat pump furnace and air conditionerYou can arrange for a representative from this team to help review your facility's heating., cooling, and ventilation demands and provide cost/benefit projections and recommendations for HVAC alternatives.best ac unit for garage Why cut a hole in the roof when you can put a smart Bard wall-mount™ unit on the side of your commercial building instead?

Bard’s vertical package wall-mount™ systems feature more enhancements than typical rooftop units, including patented features such as factory or field-installed ventilation options and control modules. Our vertical wall-mount™ units operate in the normal ambient environment, meaning much higher energy savings and a significant increase in economizer hours. DesignersThe Bard way is the smarter way to cool your building. Our wall-mount units operate in a much softer environment than 130° rooftops, which means greater efficiency, increased economizer operating hours and significantly longer life-spans. Plus, unlike most rooftop units, Bard offers active dehumidification sequence which is incredibly valuable to you when adding fresh-air ventilation to comply with building codes.BuildersJust like the mobile structures you design, Bard mobile-unit HVAC system have durability and reliability as their cornerstones. Our systems are made to operate at temperatures ranging from -30°F to +130°F and switch automatically from 50Hz to 60Hz. Bard systems are designed and tested to ensure they can take a beating on the road and still perform like champs.

OwnersWhy put an HVAC unit on the roofs where they are hard to service, cause leaks and are subjected to severe and extreme heat? Bard wall-mount units offer everything a rooftop unit does, but in a much smarter and more efficient manner. Taking your air conditioner off of your roof can save you money and significantly increase equipment lifespan of your equipment.InstallersBard units are known industry-wide to be among the most reliable and easiest to maintain HVAC systems available. Bard engineers always design our units with the HVAC pros in mind, making accessibility and diagnosis one of our top design goals. When it comes to matching today's highest efficiency requirements with yesterday's durability, no one does it better than Bard.Installation ManualsEnergy EfficiencyRenovationDurability Take a look at all we offer to see why Bard is the leader in the wall-mount industry.When customers are purchasing a new HVAC system they may be considering a ductless option, but they might want to know the benefits and the disadvantages of going ductless.

They may simply ask you, “What are the advantages of a ductless HVAC system?” and “Are there any disadvantages of installing one?” Below features a few tips on how to discuss the “Pros and Cons” of installing a ductless HVAC system with customers: Money plays a major role when consumers are contemplating an important purchase. You can begin by explaining that they will save money over time by deciding to install a ductless HVAC system. You can point out how ductless systems have the ability to run on much less power than ordinary systems because they are smaller and deliver air directly into a room.  By diving into more detail, you can explain that because they are ductless they also avoid energy losses that may come with ductwork of central forced air systems. It may also help to use some statistics such as, “These losses can be responsible for over 30% of energy consumption.” Overall you want your customer to understand that installing a ductless system essentially cuts costs and saves money over time.

If your customer is looking for a quick and easy installation process, you can explain this process and compare it to that of traditional systems. Note that traditional systems take several days and even weeks to install, while you can have the customer’s ductless HVAC system up and running in just one day. If you want to get into specifics, you can explain that the units usually run on small pipes that only require a three-inch hole through a wall, which avoids any rebuilding around ductwork. Another benefit you can call attention to is the filtration that ductless HVAC systems have. Let the customer know that the filtration system decreases the amount of dust, allergens, pollen and bacteria in the air. After you explain this, you can mention how most ordinary HVAC systems require professional cleaning regularly and can still leave behind dust and allergens. Make sure the customer understands that ductless options enhance the air quality, which allows easy breathing. Although you may have already explained that your customer would save money over time by installing a ductless HVAC system, be transparent and clarify why the up front cost of purchase and installation is higher.

You can explain the details of how the system’s efficiency and technology is more expensive to buy and install, but then remind the customer that the overall cost is lower when the system is operating. Express the importance of placement when installing a ductless HVAC system and validate your credibility. Revert back to when you mentioned the efficiency of a ductless HVAC, and explain how improper placement will cause inefficient operation and wastes energy. You can end your point by making sure the customer understands improper placement can increase utility costs. If your customer has indicated that style is essential, the indoor portion of the ductless HVAC systems may not satisfy his or her inner interior designer. You can try to identify your customer’s taste and make sure that you present certain options. Carrier Enterprise has a variety of ductless systems from Carrier, Bryant, and Toshiba Carrier to suit your customers’ budgets and styles so they can achieve the best of all worlds.
