By changing air filters, HVAC technicians play a significant part in controlling indoor air quality. These filters are made to capture allergies, bacteria, viruses, mold, and other microbiological pollutants that can have mild to severe health consequences. The highest efficiency rated types of air filters do not destroy organisms, therefore it was wise to presume they contain living diseases even before COVID-19 became a problem.
For these health-related reasons, we also inform our customers about how often you should change air filters and which air filter to pick. We know that you want to enhance the quality of the air inside their homes. Sit back and leave it to us, your contractor, to take the necessary precautions to ensure adequate and safe replacement of an HVAC air filter.
HOW FREQUENTLY SHOULD HVAC FILTERS BE CHANGED?
Standard HVAC air filters should be replaced at least once every 3 months, or as often as the air handler manufacturer suggests to maintain clean, breathing interior air. Regular air filter replacements also maintain the efficiency of HVAC systems, stop malfunctions, cut down on energy use, and lower the need for costly repairs.
WHAT IS THE BEST AIR-PURIFYING HVAC FILTER?
There are HVAC air filters designed specifically to remove viruses and other tiny particles. When changing a filter, it’s advisable to check with a qualified contractor or the system manufacturer because high-efficiency filters can impact an HVAC system’s performance.
Safety Precautions That You Should Take When Changing HVACFilter
The pandemic has increased awareness of recommended procedures for changing air filters. To keep personnel safe and stop the entry of harmful airborne infections into a home or region, there are a number of precautions to take note of. Here are some suggestions on how to change an air filter:
- Turn off the power and any nearby fans at least 20 minutes before cleaning a filter.
- Wear PPE, which should include a face mask, nitrile gloves, and shoe covers.
- Get rid of the old filter: It can be easily removed from the slot that is holding it in place.
- Look at the filter’s condition: Does it appear to be blocked with dust and dirt? The rate at which a filter clogs might vary depending on a number of circumstances, decreasing the filter’s lifespan.
- Put the old filter in a plastic bag; take care not to shake or drop it as this could cause particles to be released into the air. Close the bag with a tie and some tape for safety.
Place the filter in a trash container for disposal. If the filter has a permanent frame, it should also be taken outside. Be careful when discarding the old filter in a garbage container outside.
- When installing the replacement filter, be sure to follow the arrow on the filter’s frame, which always points away from the return air duct and in the direction of the air handler mechanism.
Make sure the arrow on the filter points away from the return and toward the air handler when you reinstall it in the housing. For future use, note the day you changed the filter.
Problems Can Occur If You Don’t Replace Your Filters Regularly
Customers must understand the damage that failing to change their HVAC filters on a regular basis may do to your heating and cooling system. Here are the top 5 issues that can happen if the filters aren’t cleaned.
1.Short Cycling
An HVAC system will frequently turn on and off throughout the day. The system will have to work harder to maintain the proper temperature, which results in higher energy usage and uncomfortably abrupt temperature swings, if the air filter is dirty.
2.Frosting Up
The air can move easily via a clean filter. In the summer, a clogged air filter prevents the proper flow of cold air, which leads to cool air accumulation inside the system. This will eventually result in ice building up on the evaporator coils, harming them and necessitating costly repairs.
3.Inconsistent Cooling And Heating
The inability of the system to maintain the required degree of comfort in the space is another disadvantage of restricted air flow brought on by a dirty air filter.
4.Accumulating Allergens
It is crucial to keep the filter clean at all times if anyone living in your home suffers from respiratory allergies or asthma. Allergens accumulate on soiled filters, where they remain for months before gradually releasing into the air.
5.Lowered Effectiveness
The cost of replacing filters causes some customers to put it off. But they should be aware that a dirty air filter will reduce the efficiency of their HVAC system as a whole. This implies that in order to maintain the temperature at the right level, it will need more electricity, which will ultimately cost your clients more money in the long run.
SIGNS THAT THE HVAC FILTER NEEDS TO BE REPLACED:
Simply knowing that you should get in touch with experts to change the HVAC filter at home is insufficient. Additionally, you need to make sure that you’re aware of the 2 most obvious warning signals that their filter is beginning to fail.
Rising Power Costs
A sudden and persistent rise in your customers’ energy bills is the first and clearest indication that they need to change their HVAC filters. The system is less effective if the filter is dirty. Your electric bill will rise as long as you put off replacing the filters, so it’s imperative that they do it now rather than later.
More dust inside the house and around the vents
Observing dust surrounding the air vents is another typical indicator that the air filter needs to be replaced long overdue. Comparing those surfaces with those farther from the air vents is the quickest approach to determine whether there is more dust present. It’s time for a new filter if the surfaces nearest to the vents are dirty but those farther away are not.
