At a minimum, all filters must be replaced or cleaned at least quarterly. This is the standard for HVAC units that are used in relatively dry and clean environments, such as office spaces. Work environments, which are mostly clean and chemical-free, are usually kept in good shape with quarterly replacements without having to worry about the unit being damaged in the meantime. The best practice is to include this in your calendar for the start of each quarter to make sure it's being done.
In general, most HVAC specialists recommend changing the air filter once every three months (90 days). When changing your air filter, it's important to consider how different air filters work so that you can achieve the highest possible indoor air quality. Pleated air filters, for example, offer higher quality filtration that effectively captures unwanted particles in the air. Conversely, low-quality fiberglass air filters may need to be changed once a month, as they are not as effective.
In controlled indoor environments, such as offices, you can expect to change the filter at least three or four times a year. Commercial HVAC units that operate in more difficult and unpredictable environments, such as medical or military buildings, will require more frequent air filter replacement. Generally, most air filter manufacturers and HVAC companies recommend changing the air filter every 90 days or 3 months. This may change depending on the location of your home (e.g.
dusty and dry climates), if you have pets, and the age of your system and equipment. If you have pets at home, you should consider changing the filter every 60 days or 2 months, and in the case of households with several pets or people with allergies or respiratory conditions, we recommend that you change the filter every 20 to 45 days. Usually, vacation homes or empty houses that aren't used much can wait to change filters every 9 to 12 months. The general consensus is that the more you use your home, the more you'll need to change your air filter.
Changing the filters on your commercial HVAC unit is an important part of any regular air conditioner maintenance plan. The frequency of replacing commercial air filters depends on a few variables, including the type of HVAC system you have, the size of the units, and the location of your building. If you're not quite sure when or how to change the air filters in your air conditioning system, don't hesitate to contact a professional. Air filters trap dirt, dust, allergens and other contaminants and prevent them from being redistributed throughout the facility.
The Minimum Efficiency Reporting Value (MERV) rating for an air filter measures how effectively the filter prevents dust and other contaminants from passing through the filter and reaching the air stream. Understanding how often you should change your air filter is a great first step to meeting a clear HVAC maintenance schedule. But all that work could be wasted if a dirty air filter spreads dirt and dust around the restaurant and kitchen. If the unit's maintenance sensors indicate that the temperature, pressure and air flow are outside the optimal parameters, it is a good sign to change the air filter.
