Choosing the Right HVAC System for Your Place of Business

MJC HVAC systems home 2aDid you know that HVAC systems count for 39% of the energy consumption in commercial buildings in the US? This fact alone, has been enough to propel companies to look for ways to design a more energy efficient method of keeping their location. But, when you also consider that use of high performance heating, ventilation and air equipment can save between 10% and 40% in energy and emissions, then looking for a way to stay comfortable, but also save money is important.

At MJC, we offer several types of HVAC systems. These range from outdoor units, portable and rental units, custom design units and gas-fired units for energy efficient systems and produce direct, indirect or heat injector systems, as well as our very own, patented Heat Injector – the most energy efficient direct gas fired heat technology available.

Considerations in Choosing an HVAC System

As you begin the process of selecting an HVAC system that will work for you, there are a number of concerns that need to be addressed:

·      Consider the various aspects of the building. From lighting to square footage, and how the space(s) will be used, to systems in the building that will generate more heat, take a moment to review the building as a whole.

·      Determine your energy goals as soon as possible. If your goal is to merely meet the energy requirements, rather than use less energy then, then your HVAC system needs will be different. This difference will be reflected in both type and size of system.

·      Plan for expansion but don’t automatically buy for it. While you may expect your HVAC needs to change in the future, it is better to buy for the needs of today. Otherwise, you will be wasting money on a system that may very well be obsolete by the time you make the space expansion.

·      Plan now for maintenance and operation needs. When you select an HVAC system, keep in mind that it will require a certain level of maintenance in order to run at its full potential. You will need someone onsite who understands the various components of your chosen system.  Ideally, these people will be trained to understand the controls and equipment needs, so that they can keep your HVAC unit running properly.

So, which type of system is best for your needs? If you don’t know, then talk to one of our MJC representatives. They will be happy to visit your location and help you assess what will be best. We understand how important it is to you to have a system that is both energy and cost efficient, and will be happy to answer your questions and concerns.

6 Tips for Selecting a Commercial HVAC System

MJC Inc Energy WheelsIf you are building a new business location, or perhaps considering upgrades for an existing one, chances are, you will need to think about the type of commercial HVAC system to install. After all, you want to keep on budget, not just in the purchase and installation phase, but also in the future as you pay energy costs each month.  But what should you look for in selecting an HVAC system? After all, that is not something that most of us have a great deal of experience in!

6 Tips for Selecting a Commercial HVAC System

As you begin the search for the HVAC system perfect for your business, don’t hesitate to ask questions. Talk to several HVAC specialists, visit other companies and find out what they have and why, and then make an informed decision. As you do your due diligence, the following tips will help.

·         Efficiency – As with any business investment, cost will always be a determining factor. But remember, that it is not the only factor. Perhaps one of the most important things to look at is the efficiency of a particular brand or type of HVAC system. Be sure that a particular unit or style will not just heat and cool, but do so in a way that works with the design and usage of your space.

·         Reliability – It isn’t truly saving you time and money if the system chosen requires frequent updates, repairs, and cleanings. Select a system noted for its reliability and minimum maintenance needs. A good way to learn how dependable a system is will be talk to others who have the same set up.

·         Size – Bigger is not always better. You don’t need a system that is larger than necessary as it will actually cost more and be less efficient. Be sure that your company’s HVAC system is the right size for the number of people who will be in your building as well as the square footage of your facility.

·         Specifications -When asking for a quote on an HVAC system, be sure to ask for one based on specifications for a standard efficiency system as well as a high efficiency system including life cycles. Typically, if the lifecycle cost is less on the high-efficiency unit, this will be the system to purchase.

·         Recycling –To minimize wasted energy, consider having a system that recycles the exhaust air stream and turns it into incoming fresh air.

·         Building Type –Areas such as warehouses and garages often do best with a radiant heating system while facilities that do onsite cooking or have heavy equipment in use do well to have a heat recovery system as a way to capture “wasted” heat and use it to offset facility heating and cooling costs.

Choosing the right commercial HVAC system for your business location doesn’t have to be stressful. Use these tips and talk to an MJC HVAC specialist to learn what type of design and system will best work for your location. We are here to listen to your needs and help you decide.

What is the Air Turnover Unit and How Does it Help?

air turnabout 2At MJC, we are always looking for ways to make heating and cooling easier, and more effective. We work hard to ensure that every piece of equipment offered goes above and beyond the industry requirements so that you get the best service possible. It is with that goal in mind that we offer the MJC Air Turnover Unit.

Never heard of an Air Turnover unit? Then allow us to explain it to you. An Air Turnover unit is a large air handler, used to supply and return large quantities of air without ductwork. The process is simple – a mass of air is discharged at or near the top of the space and the same quantity of air is returned from floor level. The air mass exchange results in a turnover of space volume. This design gamf.net makes heating and cooling large spaces more effective and efficient for spaces such as warehouses, manufacturing facilities, super mario distribution centers, and indoor sports training facilities.

The ideal application is to use fewer, larger units for both heating and cooling applications. Doing so results in the following benefits:

As compared to unit heaters an air turnabout unit uses:
· Less natural gas, hot water or steam piping
· Fewer electrical circuits
· Fewer vents and roof penetrations for gas fired heating
· Less labor

As compared to conventional heating and cooling systems the air turnabout:
· Fewer units
· Fewer electrical circuits
· Less natural gas, hot water or steam piping
· Fewer roof penetrations
· No ductwork
· Fewer condensate drains

Energy Savings from an Air Turnover Unit

The primary energy savings from an Air Turnover unit is from fan brake horsepower. Conventional Roof Top units use forward curved fans and Air Turnover normally uses airfoil prop fans. Since an Air Turnover unit is not ducted, there is less overall static and less fan horsepower is needed.

· FC fan operating at 2.00” TSP = 25 HP
· Airfoil prop fan operating at 1.2” TSP = 15 HP
· 40% Reduction in fan HP.

How Can Your Company’s HVAC System Benefit from Weatherization?

"Glass wool Insulation"There are many methods a company might implement to save money, but perhaps one of the simplest is by looking for ways to get the most from the HVAC system. Your company spends a significant portion of the monthly budget on heating and air conditioning, but what if you could maintain the comfort level, but lower the spending? One such way is with weatherization.

Weatherization is defined as the practice of protecting a building and its interior from the elements, particularly from sunlight, precipitation and wind; modifying a building to reduce energy consumption and optimize energy efficiency.” Or, simply put, it is opting for a more high efficiency approach to heating and cooling.
