The air filter is a critical air purifying device that also indicates how well a property is maintained. According Wikipedia, the air filter often comes in handy in places where air quality is an important factor of consideration such as a building ventilation system. The device constitutes fibrous materials designed to remove dust, pollen and other solid and microbial particles from the air we breathe. When solid particles build up in the filtering unit, they can cause serious respiratory irritations, which can in turn cause discomfort and common fever like symptoms. The air filter is usually located in the air handler of the air conditioning unit or next to the furnace in most heating systems.
The High-efficient particulate arrestance (HEPA) filters are highly recommended because they guarantee almost 100% filtering accuracy of 0.3-micrometer particles. The other common types of air filters include electrostatic air filter, pleated air filters, fiberglass panel filter and activated carbon air filter. Depending on usage, the air filter should be cleaned or replaced after 1 to 3 months to enhance system efficiency and reduce energy bills. A poorly maintained HVAC system such as the air conditioner and heat furnace is also likely to develop airflow problems. If you neglect your HVAC system and it becomes inefficient, you will notice one or more of the following signs according to Prism Energy:
1. Expect problems if your HVAC is 10-years or older – the lifespan of a typical HVAC system is between 15 to 20-years. The HVAC system should ideally run for only 10 years before it is replaced with a newer more efficient system.
2. The system requires new filter – one of the best and most effective strategies of ensuring your HVAC system remains efficient is simply replacing the air filters. A dirty air filter can cause serious health concerns and increase your cost of energy.
3. Experience high energy cost – most people tend to overlook HVAC system maintenance, especially when the system is running smoothly. However, failure to institute regular system inspections and maintenance can lead to costly repairs and high energy bills at the end of the month. The signs of a poorly maintained HVAC system include dirty ducts, duct leakage, reduced load capacity and disabled dampers.
4. HVAC breaks down frequently – If you notice your HVAC system is in constant need of repairs resulting from breakdown, it wise to cut the chase and consider a replacement. An inefficient HAVAC is dangerous to your health and doesn’t bode well in the economic standpoint.
Changing your heating and air conditioning unit filers on a regular basis will keep you comfortable and ensure that the air you breathe is clean and free of contaminants known to cause various health problems such as respiratory issues and allergies. In case your HVAC system calls for much more than regular maintenance, it is important to hire a professional service technician to help you discover and fix the underlying problems. The professional will also offer you important maintenance tips and schedule your system for regular maintenance.
