Filter Role in Maintaining HVAC Performance

Many homeowners with central heat are unaware that they even need a filter for their HVAC system. The filter cleans the air for two primary reasons: to keep you healthy, and to keep your heating and air conditioning equipment healthy.

For your central air system to work properly, air should easily circulate through the ducts, vents and evaporator coils. All of these parts can become clogged by dirt and other foreign particulate matter. Clogged air works means the compressor and blower have to work harder to push air through the system. They will heat up and eventually work at high energy, sub-optimal cooling modes, then fail. Dust inside the evaporator clings to the moist coils and stops the heat transfer between he air and coil coolant. You can get a recommendation for a good quality HVAC filter from your local Denver air conditioning service company. A poor quality filter will not strain out enough particulate matter to be effective.

These quality air filters also make a big difference on the quality of air you breath in your home. Your filter should stop pollen, dirt, harmful chemicals and allergens from being circulated though your home's Denver HVAC system. Along with the traditional physical filters you can also get electronic air cleaners and electrostatic filters. These offer much more filtering ability and do not need to be regularly replaced.

The electric charge on an electrostatic filter pulls dust to it out of the air. The dust is attracted from a distance, instead of having to get caught up in a tangle of webbing like a traditional filter. A HEPA (high efficiency particulate air) filter is the Denver heating professional's choice when it comes to air filtration. These filters are certified by the Department of Energy as being very effective at removing small airborne particles.

The first filters were created for work on the atomic bomb to stop the spread of radioactive particles. HEPA filters are well used in hospitals and research labs, these filters will stop most airborne viruses, mold and bacteria. Hospital filters may include a ultraviolet light to kill all organisms in the air. Airlines used to be a prime location for the transmission of disease untill HEPA filters were installed. Now airline cabins have lower dangerous organism rates than the average home. Residential HEPA filters are also available and you HVAC company would be happy to help you install one.

Controlling Indoor Air Pollution with HVAC Equipment

Pollution within structures is often many times worse than outside because pollutants do not have the whole atmosphere to be diluted in. Especially in manufacturing and heavy industry applications, proper ventilation is necessary to have workers on site. Workers are very vulnerable to indoor pollutants because they will receive continued exposure to them for the duration of their time on the job.

The first step in maintaining proper ventilation in a work environment is to identify all possible pollutant vectors, as well as all the inlet and outlet air ports in a building. Buildings are usually not near air-tight, so harmful fumes can enter or exit from many unusual of locations. Consult with a Denver HVAC company to identify all the natural and man-made ventilation points in your building. Natural points are windows, doors and leaky walls, while man made ventilation points are things like ventilation ducts and blow-off valves.

Not maintaining proper HVAC ventilation puts your company at risk for workplace injury and lawsuits. The first thing a possibly injured worker will do to determine if they are getting sick from improper building ventilation is to leave and see if the symptoms subside. There are a wide range of symptoms and possible indoor pollutants, so it is best to get and idea of what they are and how to address those pollutants from your Denver heating company instead of the local lawyer. Without a vigilant HVAC company or workforce to report problems, many dangerous gases are not noticed until a Denver furnace repair services technician notices something strange. Unfortunately, there are too many stories to count of Denver HVAC techs working in refineries with dangerously inadequate ventilation.

Not controlling these fumes can lead to "sick building syndrome" where workers feel lethargic and sick when at work. In public institutions like hospitals and schools, these symptoms must be taken very seriously because children's immune systems may have less natural ability to fight off toxins. A HVAC system with the central air hooked up to filters and scrubbers will take care of most harmful substances on non-industrial applications.

The major culprits to get people sick inside buildings are: tobacco smoke, burnt combustibles like exhaust smoke, biological pollutants like mold or viruses, volatile organics like solvents and jet fuel, and heavy metals like lead or any other smelter fumes.
