Filter Maintenance

Introducing the correct air filter for your HVAC system is imperative to save you money and energy, prevent needless repairs and breakdowns, and increase the longevity and effectiveness of your HVAC system.  Given that filters are inexpensive and disposable, there is no excuse to damage your heating and cooling system due to neglect.  Change them every 3 months.

Filters are inexpensive but we must remember that when looking for filters, we must not sacrifice quality for price. The least expensive filters may not be effective in ridding pollutants in the air. These pollutants may result in health problems and expensive HVAC breakdowns.

A lot of products have been made available to help us in increasing our indoor air quality while keeping comfort levels relatively high and energy consumption and bills low. These include air quality systems and product specially designed to improve indoor air quality such as air purifiers, dehumidifiers, and energy recovery ventilators. However, in order to experience the benefits offered by these products, it’s important that you hire a trained expert for installation, repair, and maintenance.

Be aware that while air quality products are important, if installed improperly, they will not achieve the results you are expecting.  They might even affect the operation of your existing system negatively and even lead to their permanent malfunction and failure. The whole purpose of installing an air quality system is to improve your home’s indoor air, so it is important to leave it in the hands of experts.

The primary purpose of a filter is to protect HVAC equipment, not to improve indoor air quality, as many homeowners have been led to believe. Many furnace manufacturers recommend that you use a low-cost fiberglass filter, but when I asked a representative of one major maker, his response was “no comment.”

Perhaps this was because high-efficiency filters that are too good may actually slow airflow across the heat exchanger, reducing the unit’s efficiency, raising your energy bills, and causing furnace damage due to overheating. Similarly, a high-efficiency filter can freeze the condensing coils on an AC unit. (A dirty filter can do the same thing.)

Heating, Ventilation and Air Conditioning, also known as HVAC, systems exist to help us maintain the quality of our indoor air good and our comfort levels high trough providing adequate ventilation and thermal comfort.

Better conditions and air quality for families and people in a building is ascribed to proper air filtration and maintenance. This also improves the efficiency of the unit and increases its longevity.

HVAC Air Filter Efficiency Ratings

Placement of air filters within a buildings ventilation system can block airborne particulates that can include, animal dander, pollen, mold spores, bacteria and viruses depending on the Minimum Efficiency Rating Value (MERV) of your air filters. For an HVAC system it is recommended that you use air filters with MERV Rating between 8 and 13. The higher the rating, the more contaminants that will be blocked and therefore will result in better protection of the equipment and building occupants.

Air filters were made to clean the air we breathe by removing pollutants. Failure to adhere to this purpose may result in poor indoor air quality. These contaminants may cause asthma and allergies, headaches, skin rashes, and other health problems that may decrease comfort levels.
