Why Schedule Commercial HVAC Maintenance This Winter?

During the winter, your Central Air Conditioning (HVAC System) is constantly working to keep your business comfortable. Commercial HVAC Maintenance is important because several issues arise within the wintertime that will result in expensive repair costs. If you choose not to get your commercial HVAC systems serviced this winter, the costs of repair will outweigh the costs associated with preventative maintenance.

Here are three reasons why you should schedule commercial HVAC maintenance this winter:

1) Prevention of Breakdowns

From January to March is when our Central HVAC Systems experience the most wear and tear, leaving them particularly susceptible to breakdowns. The winter months are especially hard on our AC units. During winter, we run our heating and cooling constantly as we try to stay warm inside and pull the warmer air outside. This puts a heavy load on HVAC Systems as they try to keep up with daily temperature fluctuations. Preventative maintenance this winter will help your HVAC system last longer and more efficiently.

2) Repair Costs of Broken Parts and the Cost of Replacing These Parts

If your HVAC System experiences a breakdown this winter, you can expect high repair costs as winter is the time when repair companies are most booked. It may be difficult to find a company that can come out and fixes your Central HVAC System on short notice, not to mention the high cost of a same-day service call. Normal wear and tear of a Central HVAC System can cause broken parts that will need to be repaired or replaced. The costs of such parts add up quickly and can be expensive. Preventative maintenance this winter will save you money in the long run by helping to prevent repair costs in the future.

3) Preventative Maintenance Can Identify Potential Problems With Your Central HVAC System

Preventative maintenance is an excellent way to save money on repairs down the line. Preventative maintenance is a service that allows a certified technician to thoroughly inspect a system for problems and wear and tear. The preventative maintenance service will provide a technician the opportunity to identify potential problems, such as clogged or dirty filters, worn hoses and belts, and refrigerant leaks. These problems can escalate into major repairs that would otherwise not need to be done if you had your HVAC maintenance performed this winter.

Identifying major HVAC problems early is ideal as it allows you to take immediate action before any permanent problems develop. If you are interested in learning more about preventative HVAC maintenance this winter, contact a professional commercial HVAC company.

5 Signs it’s Time to Replace Your Commercial Furnace

While it’s not the most enjoyable thing in the world, there comes a time in every furnace’s life when it has to be replaced. As much as you would like to believe that your furnace will never need replacing, it can be all too easy to notice signs that it is on its way out. If you take care of it, it will take care of you. Keeping on top of maintenance and repairs can help increase the lifespan of your furnace by up to 15 years in some cases. If you want to make sure that you are acting before something goes wrong, here are five key signs that it is time for a new commercial HVAC system or commercial heating unit:

1. Your commercial HVAC unit is over 15 years old

2. You notice a fall in your furnace’s energy efficiency

3. It’s starting to give you the heebie-jeebies – literally!

4. Constant repairs and maintenance are no longer an effective solution

5. A dirty commercial HVAC commercial heating commercial air conditioner commercial furnace commercial unit

You can check to see the age of your commercial HVAC unit by looking at the sticker or nameplate. If it is more than 15 years old, even if it’s still in good working order and you maintain it regularly, chances are that changing technology has made a replacement commercial heating commercial air conditioner commercial furnace commercial unit a better option. You can also refer to your energy bills – if they are up 15 percent over the last couple of years, it is probably time you considered replacing your commercial HVAC commercial air conditioner commercial furnace commercial unit.

The more efficient your commercial HVAC commercial heating commercial furnace commercial unit is, the lower your energy costs will be. If you find that commercial furnace systems are costing you more and more money or aren’t operating at their highest level of efficiency, it may be time to get a new commercial HVAC system installed.

What To Know About Eddy Current Testing

Eddy current testing is a way for those who work with specialty metals to test for imperfections, such as cracks or gaps. These flaws are detected by electromagnetic induction. It can catch these flaws on the surface of the material, but also in the sub-surface. Not only that, but eddy current testing can also be used to measure the conductivity and thickness of a material. Here are some things that you might find interesting about eddy current testing.

Nondestructive Testing (NDT)

Eddy current testing is categorized as a nondestructive testing method. This means two things. For one, the system is reliable, safe, and cost-efficient. The other is that the testing is conducted without causing harm to the material or any parts connected to it. It will also do nothing to affect the use of them in the future. There are several NDT techniques, including simply using the eyeball test, and eddy current testing is one of the most important.

It is Vital in Everyday Life

It may surprise you to hear that eddy current testing is an important part of our lives, but it is absolutely true. Eddy current testing is used in many industries and for many of the products we interact with daily. As an example, eddy current testing is the preferred method to use for testing oil and gas pipelines, chemical manufacturing, nuclear reactors, and our local water systems. There is portable equipment for eddy current testing to perform inspections on site, such as on bridges. Public safety is greatly enhanced by using eddy current testing, which makes it important to us. Not only can it be used for those large components, but it can also be used for smaller parts that also have an impact on safety.

Different Probes Depending on the Mode

ECT uses test probes that come in several styles and sizes. They do not just have different shapes, but also have varying modes of operation. Take, for example, an absolute measurement probe. This probe creates eddy currents by using a coil. These currents then track any changes in the current field. Another probe has two coils, so that the operator can use comparisons to find flaws. If there is a coil lingering over an imperfection, and the other is over a good spot, then the operator gets a signal.

There are Several Factors That Can Affect Eddy Current Testing

Eddy current testing equipment generally comes with several settings. There is amplitude, frequency, and sensitivity, among others. These all need to be considered when performing ECT. That said, there are other factors in play as well. You must consider anything that might affect the flow of the currents, such as any properties of the material you are testing. If there are obstructions, then an adjustment to the settings may be required.

Magnetic permeability is one of those factors that can affect how easily the currents flow through a material. When measuring permeability, there can be interference created when using ferrous materials. That makes it hard to use eddy current testing for accurate results. To get over this, technicians can use magnetic saturation or different coil arrangements to get accurate readings.

When it comes to interference, even ambient room noise can cause problems for eddy current testing. The best option is to try to filter out any noise in the environment to get a good signal. There can also be issues if the part or material being tested has sharp or geometrical edges. Technicians can use a special scanning technique to overcome this.

The eddy current testing procedure is used on several materials, such as tungsten and molybdenum rods. It is an effective way to inspect materials for damage, cracking, fractures, and pitting.

A Guide to Pneumatic Control Systems

You may have heard of pneumatics before, but may not really know what it means. At its most basic, pneumatics involves using pressurized air or gas. A pneumatic control system helps to control an HVAC system by using compressed air. Here is how a pneumatic control system works.

Process

The compressed air used by a pneumatic control system is pushed through plastic and copper tubes. It starts from a controller, and travels to a controlling device, which is most often a damper or a valve actuator. There are sensors attached to the lines that measure any changes in temperature, humidity, static pressure, and other factors. In effect, the compressed air is the method by which all of this data is communicated. A thermostat will be connected to these lines and will regulate the air accordingly.

Actuators

Pneumatic actuators are the motors that drive the whole system. They control the valves and dampers. They are extremely durable and reliable, and are very cost-effective. There is no need for regular maintenance on these actuator types, either. In just about every factor, whether it be durability or affordability, these actuators are superior to electric actuators.

Modular Control Components

The components that make up the system provide excellent performance and versatility. These components, such as receivers, thermostats, and pneumatic relays, can be custom configured to fit your building’s needs. No matter what, they will relay the necessary data accurately regardless of how the system is configured.

Limitations

Despite it being an uncomplicated system, there are some limitations to pneumatic controls. Because of its simplicity, building managers often overlook or forget the need for quality preventative maintenance. It is not a process that can be handled by just anyone. The air supply should be checked regularly to make sure that it is clean and dry. Also, a regular maintenance program is required to inspect all components of the system. Every two years or so, components should be adjusted to make sure there is no shifting of the setpoint.

Maintenance and adjusting are best handled by professional contractors who know the ins and outs of pneumatic controls. They will make sure that your system is running smoothly and efficiently at all times.

‘Green Ductwork’ Gaining Popularity As Industry Standards Improve

We live in an eco-friendly world. Politics, science, business, public safety. Evidently nothing has been left behind when it comes to going green. Hence a new trend that’s making waves in the HVAC industry. ‘Green ductwork’ is a new term that more and more HVAC professionals are becoming familiar with. While there is no finite definition to the new term, most everyone associates it with recycled materials related to ductwork and other HVAC materials. New standards set by the U.S. Green Building Council’s LEED (Leadership in Energy and Environmental Design) program are continuing to drive improvements in green materials and improved awareness of public health and environmental concerns.

Green Ductwork

Eco-Friendly Materials

According to LEED’s page on the U.S. Green Building Council’s website, “LEED-certified buildings are resource efficient. They use less water and energy and reduce greenhouse gas emissions.” As a result, new HVAC equipment is being developed from recycled materials that have a lesser impact on the environment. Polyester, for example, is being used to make fabric ductwork. Fabric ductwork is lighter than traditional metal. It requires less roof or tether support and uses linear dispersion to eliminate hot and cold spots. These advances make more efficient HVAC systems that are also simpler to install and create less solid waste.

Cleaner Air

A major component of green ductwork is its ability to remove contaminants from the air. One of the biggest pushes for more eco-friendly building materials is public health. Consumers are more aware of volatile organic compounds (VOCs) present in various products. Most HVAC systems are lined with insulation for noise reduction. Consequently insulation in building ductwork puts contaminants and other particles into the airways and makes people sick.

Increased Efficiency

Increasing HVAC efficiency is another major part of ‘green ductwork’. Leakage in ductwork forces the system to use more energy. Consequently you end up with higher energy expenses and decreased efficiency. HVAC contractors are currently looking for the most cost-effective way to improve ductwork efficiency. Some apply gasket fittings while others go back in and seal the system with a commercial-grade sealant. Sealants effectively limit energy use and minimize emissions. Consequently you spend less and do more for the environment.

Industry standards are cracking down on faulty HVAC equipment. Consumers continue to look for more eco-friendly products to use in their commercial space. Don’t be left behind. Contact the professionals at Corporate Mechanical today. We are up-to-speed on all the current industry trends. Our representatives are ready to answer your questions and offer you real solutions.

More Ways to Prepare a Building for Winter Weather

People are usually well-versed in ways to winterize their homes, but can sometime neglect to apply the same treatment to their commercial buildings. Understanding the precautions necessary to winterize your commercial property is important to maintaining the operations of your business.

Maintenance for the Building

  • Make sure that gutters have been cleared of any objects, including leafs or other organic material. This ensures proper draining during the cold months.
  • Make sure that nothing is blocking your drains. If moisture is not draining properly in the winter, it could cause significant damage. Inspect and roof flashing penetrations or building envelopes as well, and seal them to prevent water from flowing into the building.
  • Inspect gutters to make sure they are properly attached to the building
  • Make sure any accumulated debris is removed from basement and foundation drains, especially the storm drains in the parking lot.
  • Trim any nearby trees or large shrubs to reduce the amount of leaves or branches that could enter the drains
  • Service your heating equipment early. This will ensure that nothing breaks down when it is being used constantly during the winter.
  • Test all carbon monoxide detectors
  • Discourage the use of space heaters, but in cases where they are permitted, make sure they have a UL label

Removing Ice and Snow

A representative for a Denver roofing company offers the following pieces of advice:

  • Make sure you already have the proper tools before winter. This includes shovels, salt and other material to melt the ice, and anything else necessary to facilitate the removal of snow in your area.
  • Review any contracts you have with the maintenance crew if you have hired one. This will reduce the amount of unanticipated bills later in the winter, and ensure you receive the service you desire.
  • Make sure your exterior lighting works. This makes it much easier to remove ice and snow during the evening when the building is closed for business.
  • Start any parking lot repair before winter begins, especially pot holes and curb damage.

Preventing Frozen Pipes

A spokesperson for Asbestos Abatement in Denver offers the following:

  • Make sure any irrigation system is turned off. This will keep water inside the pipes from freezing.
  • Make sure any wall or attic pipes are sealed to prevent airflow near the opening.
  • Consider a temperature alarm in any high risk areas, and add extra insulation near pipes in your attic or basement
  • If possible, let a sink drip if it happens to be in an extremely cold area (only if the water cannot be drained or turned off).
  • Make sure all your windows and doors have the proper sealant, especially if they are in an unheated area of your property.

7 Ways to Winterize a Building

An unpleasant fact of life is that a lot of the energy in your structure or commercial structure spent on heating is wasted due to failing insulation and lack thereof. If you address a lot of the issues you will have a chance to make that a thing of the past, so consider what you can do to make it happen. With the proper insulation, your structure and its HVAC system will be much easier to work with and they won’t waste as much energy trying to keep your building warm. The biggest consumers of energy happen to be large appliances such as freezers, water heaters, dishwashers and washing machines, but HVAC systems can also eat up a lot of energy when they are working with poor insulation. You can work on this before the winter season, allowing you to install all of these and to deal with house cleaning when the job is done. Be careful when working as you may need to perform upholstery cleaning and carpet cleaning if you work with foam. The following examples will explain how you can winterize your building properly to avoid any issues up ahead:

Benefits of Regularly Maintaining Your Furnace

With the summer warmth, many people forget that the fall and winter are just around the corner and that soon temperatures will start coming down. Those who are conscious of the coming winter do their best to get ready by inspecting their roofs, cleaning gutters and disconnecting their hoses but forget a very important equipment in the home i.e. to check whether their furnace is working properly. Following are benefits of having your furnace maintained regularly;

It limits surprises. Ensuring a regular maintenance to your furnace has a host of benefits. With such maintenance, you have peace of mind knowing that you are not likely to experience furnace emergencies when the cold is really biting. Imagine the furnace breaking down on a very cold night just because you didn’t have it inspected earlier? Regular maintenance reveals in advance small problems which could turn into big problems if left unchecked. When you get your furnace checked before winter sets in is very wise as it gives you time to order replacement parts if they are needed, you are also able to check its efficiency to ensure it heats your home effectively as well as order a replacement unit if you find your old one in a deplorable working condition. You don’t want to rush to put on the furnace when the chilly weather sets in only to find out that it is not heating effectively and worse it doesn’t heat at all.

Increase your unit’s efficiency and lifespan. Fall furnace maintenance also helps review your unit’s efficiency. If properly maintained, a furnace can last as long as 20 years or more. Having a professional HVAC technician clean, lubricate moving parts, check connections and check its control’s among other maintenance procedures will ensure your unit operates at maximum efficiency. With such maintenance you will greatly save on your energy bills.

It limits unnecessary repairs. Ensuring a regular maintenance to your furnace will limit the need for repairs over the lifespan of your unit. This translates to less operation costs for the unit. In addition, you are able to last all winter long without having a serious furnace repair or breakdown that leaves you spending a number of nights on the cold.

Be wise this fall, call for a certified HVAC repair technician to come and check your unit. Also, if you can, enroll in a regular maintenance program which ensures the repair company will always come to check your unit even when you forget about it.
