Getting the Most From Your HVAC Systems

By Jon Levine

Does your HVAC system operate as efficiently as it could? Is your HVAC system compliant with health, safety and environmental regulations? Do you face continual maintenance issues with your HVAC system? In other words: is your HVAC system in good shape, or is it costing you a bundle for no good reason?

With any facility assessment, one of the first areas to check out is the HVAC. You need to determine how much time you have left on the system’s lifecycle. If your HVAC system is extremely old, it could be sucking up energy and wasting your money. It could also be causing indoor air quality issues that lead to problems like Sick Building Syndrome. Or, your old HVAC could be racking up big maintenance bills. If so, then you need to know what’s wrong so you can fix it.

Energy use is a good starting point because the opportunity for cost savings is significant. Lighting tops the list of the potential savings, but HVAC runs a close second. Did you know high-tech HVAC systems could save 30 percent to 40 percent on energy costs? That’s nothing to sneeze at. The return on investment on HVAC upgrades ranges from one to five years, depending on the system’s level of use. That’s well worth the money, considering HVAC systems can last 10 or more years, depending on usage and climate conditions.

Interestingly, the design of an HVAC system has major impacts on productivity and energy savings. If you don’t have good controls on your HVAC, then you are wasting tons of money. It could be that you are simultaneously heating and cooling different parts of the building at the same time. That’s counterproductive and puts a lot of strain on the HVAC.

According to the California Energy Commission, an HVAC system should be properly sized to provide correct air flow, and meet room-by-room calculated heating and cooling loads. It should also be installed so that the static air pressure drop across the handler is within manufacturer and design specifications to have the capacity to meet the calculated loads.

Beyond the proper design and installation, experts encourage regular HVAC maintenance to ensure the best operation. Air filters should be changed each month, for example, and HVACs also need to be properly charged with refrigerant and have proper burner operation and draft.

If you do not have an HVAC maintenance crew on site, be sure to contract with a local air conditioning maintenance company to do regular check ups. This will extend the life of your HVAC and save money on heating and cooling costs.

Have Your HVAC System Serviced Annually

By Budda Oliver

Almost every manufacturer of furnaces and HVAC systems recommend that you have the unit inspected and serviced at yearly intervals. However, many people overlook this necessity and forego service for longer periods of time, either due to cost issues or forgetfulness. Skipping annual service on you HVAC system could lead to spending more money in energy bills, not to mention put the health and safety of you and your family at risk. A licensed HVAC service technician will ensure your HVAC unit is operating properly and at maximum efficiency – which will save you money and heartache in the long run.

If you have an oil or natural gas furnace, your HVAC system burns fossil fuel. The burning of these fossil fuels can result in a deadly byproduct – Carbon Monoxide. An HVAC service technician will make certain that there is no risk of carbon monoxide poisoning coming from your furnace. Even small leaks can be hazardous, so an annual service inspection to check for the deadly poisonous gas is highly recommended.

Also, furnaces that use oil or natural gas are also at a higher risk of fire because these fuels are highly flammable. An HVAC specialist will ensure your unit is operating properly and is clean of dirt, dust, debris and other materials that can easily catch fire.

One of the most advantageous benefits of having your HVAC system annually serviced is maximizing its efficiency. Home heating fuel is very expensive, so making sure your HVAC system is burning it at an efficient rate is directly related to the amount of your energy bills. A professional HVAC service technician can adjust your furnace to ensure it is operating at its highest efficiency. Inspections and “tune ups” will result in less fuel consumption and lower bills.

Having your HVAC system serviced on an annual basis is a great way to have preventative maintenance done. It is recommended that annual service be performed before the winter months to ensure the furnace will work properly throughout the cold season. Often times, an HVAC contractor will notice potential problems before they begin and offer solutions for repair or replacement of parts. This can be extremely beneficial to a homeowner because they will not have to go through the struggle of having their furnace break down in the dead of winter, leaving their family with no heat for days or weeks until it can be repaired.

The advantages of having a furnace inspected and serviced by a professional HVAC technician are tremendous. You’ll save money on your fuel costs and energy bills, and have peace of mind that your furnace will run properly on even the coldest of winter days. Your be sure your HVAC system is operating safely and at the highest efficiency by hiring a professional HVAC engineer to inspect and service your furnace on a yearly basis.

Choosing the Right HVAC System For Your Project

By George Chappell

HVAC stands for heating, ventilation, and air conditioning. These systems provide the indoor climate control for both residential and commercial buildings. When it comes tothis, one size does not fit all. As a matter of fact HVAC systems can be quite complex. Determining the right type of system for your home or building is extremely important for the system to heat and cool effectively and to be energy efficient as well.

HVAC systems come in many types and applications. They are classified as either central or local. The central air conditioning and heating system provides the necessary heating and cooling and ventilation from a central location in the building such as from a boiler or furnace. It works by circulating heated water or steam through piping or ductwork to achieve heating and cooling.

Central air conditioning units use a compressor and a condenser unit that uses a refrigerant or coolant such as Freon. The refrigerant is circulated through copper tubing. The refrigerant absorbs the heat, turns to vapor, travels to the compressor, and moves to the outdoor coil where the heat is forced out. Then the refrigerant passes through a device where it is converted to a low pressure, low temperature liquid and returned to the indoor coil. The cool air is then circulated through the ductwork to provide cooling for the structure.

Local HVAC systems are devices that provide heating and cooling to immediate areas or rooms. They do not circulate throughout entire structures. Local HVAC systems may include wood or pellet stoves, window air conditioners, and space heaters. Electric baseboards are also considered to be local HVAC systems if the unit is installed into a single area.

Determining which HVAC system is right for you and your needs should be determined by an HVAC professional in order for you to get the maximum benefits from the system. A qualified and certified HVAC contractor will determine the type unit that is best for you and will install the unit in the proper place so that it will meet your cooling and heating requirements.

Modern HVAC Systems

Heating, Ventilating and Air Conditioning (HVAC) systems help to regulate the climate and maintain the indoor air quality of homes and commercial buildings. While sophisticated and reliable HVAC systems have become common in daily modern life, they have not always been so widespread. However, the principles that these systems operate on have long been known to scientists and engineers. Even though advances in the reliability and cost effectiveness of HVAC systems continue to improve, we enjoy very mature technology from this industry segment today.

The modern air conditioning system has been in continual development since its invention in 1902 by Willis Haviland Carrier. The system that Carrier invented was used in a printing plant to regulate the temperature and humidity of the air, thus causing the process used there to operate more consistently and reliably. Thereafter, the demand for commercial air conditioning exploded and Carrier formed his own company. It was not until the 1950s, however, that residential air conditioning became wide spread.

Because many early air conditioning systems used toxic and flammable gases to produce cooling, their utility was limited, so in 1228, Thomas Midgley, Jr invented the first chlorofluorocarbons (CFC) for use in refrigeration systems. This became popularly known by the DuPont brand name Freon, and it greatly enhanced the safety and reliability of refrigeration and air conditioning systems. However, in the 1970s scientific studies were starting to show that the release of CFCs into the air was depleting ozone levels in the stratosphere, resulting in higher incidence of harmful solar ultraviolet radiation reaching the earth’s surface. Because of government action, the use of all CFCs and related chemicals have been restricted and are expected to be completely phased out by 2010. Newer non-ozone-depleting refrigerants have been developed and are being phased into HVAC systems currently available on the market.

Our understanding of properly engineered HVAC systems was further advanced after the World Health Organization (WHO) issued a report in 1984 on Sick Building Syndrome (SBS). SBS was found to result from poor indoor air quality, and several solutions have since been developed to prevent this condition from developing. Proper maintenance guidelines for HVAC systems can help to prevent SBS; additionally, the use of an air-to-air heat exchanger can be employed to increase the amount of fresh outdoor air that is brought into a building without sacrificing energy efficiency. The current recommendation from American Society of Heating, Refrigeration & Air Conditioning Engineers is to provide 8.4 exchanges of air within a 24-hour period.

With increasing costs for energy a primary focus, continued research today is improving the energy economy of HVAC systems. In an effort to reduce the ecological impact of new and existing building design, the U.S. Green Building Council promotes adherence to a set of guidelines known as Leadership in Energy and Environmental Design (LEEDS). Energy efficient HVAC systems are an important component to the success of the implementation of LEEDS standards.

Today we enjoy safe, efficient, and reliable HVAC technology. As an essential part of our daily lives, these systems will continue to be adapted to our changing needs by today’s graduating scientists and engineers.
