Data Center Cooling Solutions

Your commercial air conditioning units are probably protecting other, more visible systems. Unless you’re in the facilities management field, you probably think more about your data center cooling than you do about the commercial air conditioning units that keep everything cool and safe.

data center coolingAs any company grows, the need for all of these systems grows at the same time, and basic to all of them is the commercial air conditioning that protects and cools your data centers and a variety of systems that are critical to the operation of your business.

Having worked for both larger data centers and third-party hosting companies, we think it’s important for smaller companies with smaller maintenance budgets to learn from the bigger players. Even with skeleton contingency plans, an old server in a hot closet is probably not going to meet your data center cooling needs for more than a short time.

With copies of the same data saved across primary and back up servers, simple demand for more space for computing and data storage increases demand on your commercial air conditioning too.

Even as more storage moves into remote and cloud based storage, some kind of data center cooling will need to be be maintained on site. Commercial air conditioning repair can seem grossly inconvenient. It may test your contingency and back up systems, but any down time is likely going to stress not only your systems, but your staff and profits too.

In consulting with information officers and related technical staff, we’ve worked on a range of projects that have involved installing data center cooling solutions using existing commercial air conditioning units, both of onsite primary systems and contingency systems in remote locations. We’ve also worked to minimize the need for costly commercial air conditioning repair.

Maintaining support systems during power outages or natural disasters often takes precedence, at least in theory, over maintaining commercial air conditioning units. In some cases, technical staff need to be familiarized with the facilities staff taking care of contingency power, security and fire-protection systems as well as the commercial air conditioning units themselves. That’s something you might only learn during a contingency drill or testing period. If you are planning a commercial air conditioning repair in your primary work location, it might be a good time to plan for contingency testing and roll-over to a back up system.

Small and mid-size data centers with limited budgets and staff need to rely on data center cooling that’s well maintained and that won’t break down. The cost in over heating servers or data loss could be incalculable. Even interruptions while a commercial air conditioning repair takes place can be unduly expensive.

Identifying operating and maintenance issues prior to scheduled commercial air conditioning repair or downtime is vital and some smaller data centers will even schedule downtime to coincide with the repair. In every case though, it’s important to realize that your commercial air conditioning is just as vital as the data it’s protecting.

Heating and Air Conditioning Contractors What to Expect

Heating and air conditioning includes some of the most important, difficult and expensive equipment you’ll likely purchase for any construction job. Somehow, less reputable heating and air conditioning contractors struggle on in spite of questionable reputations and in part because the expense of a good job can lead to high returns even without customer referrals.

That’s not how we do it, but in a city like New York City, heating and air conditioning contractors will come and go. Some bad ones will even linger on despite a trail of complaints over heating and air conditioning repair jobs that have gone bad.

Heating and air conditioning repair have developed into highly technical fields that require years of training and experience. Today’s heating and air conditioning contractors are often factory trained and licensed to install heating and air conditioning, to handle potentially hazardous materials, and to provide heating and air conditioning repair where necessary.

Finding the Right Heating and Air Conditioning Contractors

heating and air conditioning contractorsFirst identify and contact several heating and air conditioning contractors.

Set an appointment with several to visit your home or facility. This visit is free. They’ll inspect your existing HVAC system and collect information about your home and needs and use it to calculate the heating or heating and cooling load for the HVAC system that they’ll propose to install.

You should ask for and expect no less than 3 good references for both heating and air conditioning clients and know what to ask when you call the references. Call all of them and verify where the job was performed, the nature of the heating and air conditioning repair or installation, and that they were satisfied with the job.

A written estimate that itemizes costs for labor and for the appliances themselves – and for the individual tasks necessary to get it installed – is the next step. Compare the estimates from each of the contractors and ask for an explanation of any wide variations. Particularly if one contractor has noticed a heating and air conditioning repair or modification that the others missed, you’ll want to know what it is.

You may want to have your lawyer look over any contract before it is signed. A lawyer will make sure that the contractor’s papers, license and insurance are in order and they can also see that warranties are understood and in order.

Heating and air conditioning repair or installation can be expensive and time consuming but if you approach it with the right attitude, you’ll come up more than satisfied. Have questions? Please call 646-783-2475.

What are EER and SEER?

EER and SEER are two more factors to consider when purchasing your new air conditioner or HVAC appliance. Unfortunately, knowing which unit to buy can depend on more factors than most people want to deal with. The purchase of an incorrect air conditioner can be an expensive and hazardous mistake.

Both EER and SEER offer a way of describing the energy efficiency of a given air conditioning appliance. The higher the number, the more energy efficiency and thus the less it will cost you to run it for a year. Smaller air conditioners usually have a top EER of about 11, and bigger air conditioning units can top out with an EER of about 13. A larger HVAC system will display an SEER rating – these are always higher numbers – but they should not be confused.

What does EER and SEER Stand for?

EER is generally used for smaller air conditioners and window mounted units. SEER is almost the same measure but more commonly used on central HVAC systems and larger central air conditioners. EER stands for Energy Efficiency Ratio while SEER stands for Seasonal Energy Efficiency Ratio. Both of them are based on the total BTU (Britsh Thermal Unit) output per hour divided by the watts of electricity consumed.

The important difference is that EER is calculated for a smaller controlled environment such as a room or apartment. SEER, on the other hand, is calculated by including numbers for the cycling of the unit on and off and seasonal temperature variations where the unit is likely to be installed. Temperature and humidity can therefore be important to the the relationship between the two measures.

eer and seer enery guide labelEER is calculated assuming a 95 degrees outside temperature and an inside temp of 80 degrees at 50% relative humidity. SEER is calculated at the same indoor temperature, but at between 65 and 104 degrees outside temperature to simulate seasonal variations.

A really good consumer guide will calculate annual costs for running air conditioning based on the cost of electricity in your area and the EER or SEER ratings of the air conditioning appliances being reviewed or sold. If you’ve ever gotten knocked out by an electricity bill, you’ll know why this is important.

Usually the yellow Energy Guide label  in the store estimate costs based on a national average of 8.4 cents per kilowatt-hour which makes for very low cost estimates, if not for bad air conditioning unit sales.

One of the mistakes consumers commonly make is in determining exactly how much cooling capacity you need. As opposed to EER, cooling capacity is written in the store as BTU/hour units; the higher the number the higher the cooling capacity.

Getting an air conditioner as close to the correct cooling capacity as possible is important. Energy efficiency and correct cooling capacity go hand in hand when it comes to saving on electricity and still being comfortable. If you’re thinking or replacing your air conditioning or your HVAC system, give us a call. We’ll be happy to discuss a machine rated appropriately for New York City and for the size and use of the building or apartment you’re hoping to cool.

Energy Efficiency Air Conditioning Tips

energy efficiency air conditioning tipsEnergy efficiency is possible during the New York City summer heat. These tips are designed to keep your place cool, while minimizing the energy consumption of your air conditioner. Efficient air conditioning doesn’t always require that you keep the temperature up, but it will help to take some simple steps to maximize the cool air.

Get a new air conditioner – This might seem the easiest thing of all to do, but the cost savings on energy consumption that you can realize with newer, more efficient air conditioning unit can be outstanding. You could actually make up for all the money you’re losing on an outdated, less efficient air conditioning machine.

Get it serviced – Regular air conditioning service should include a complete inspection once a year and air filter changes as the manufacturer recommends. That alone will keep the energy consumption to a minimum and keep the newly energy efficient unit running for years to come.

Keep the sun out – Draw the blinds. Pull the curtains. Energy efficiency really will grow in the cool interior. Every time you leave your home, or during the hottest days at the hottest hours, keep it dark. Efficient air conditioning is as easy as giving the air conditioner a break.

Use fans – A few well positioned oscillating fans or energy efficient ceiling fans will go a long way toward reducing the load on your air conditioning.

Automate the thermostat –  Newer air conditioners can be programmed so that your home may be a little warmer while you’re out and so that the unit comes back on just before you get home. That’s in addition to the energy efficiency built into a newer machine.

Change your bulbs – Energy efficient light bulbs will not just reduce the energy consumption used for lighting. They also burn a lot cooler, and reduce the heat produced by lighting your home.

Turn down your water heater –  Cooler, shorter showers will keep hot, humid air out of your living space and make your entire home more energy efficient.

Check for leaks – Your air conditioning, and your energy efficiency, depends on controlled air flow. Make sure gaps around any pipes, vents or wiring are sealed and check the vents and airflow vents that flow to or away from the air conditioning appliance.

Get the kids out of the house –  Spending more time outside will reduce the heat, energy consumption and load on the air conditioning. It might seem like a long way to go to make your home more energy efficient, but it’s a healthy and cost saving way to increase your home’s overall energy efficiency.

Feel free to call us if you have any questions regarding energy efficiency, or air conditioning maintenance. 646-783-2475.
