How Do You Know You Need to Replace Your Air Filters?
One of the important parts of an HVAC system that affects the system's operation and indoor air quality is the air filter. An air filter removes contaminants such as dust, pet dander, animal fur, mold, dirt, and bacteria from the air flowing through the HVAC system. Besides improving your home's air quality, the air filter also protects your unit from damage.
To maintain a healthy home and prevent premature replacement of your unit, you'll need to change your air filters often. Changing air filters can help improve your unit's efficiency, reduce energy bills, prevent frequent breakdowns, and promote your health.
But how do you know you need to swap your air filter? Check out the top signs that you need to replace your air filters.
Spike in Utility Bills
If you're witnessing an unexplained increase in your home's electricity bills, the culprit could be your air filters. A dirty air filter will impede the normal airflow in your system. Your AC will need to work harder to blow the air all over your home. As your AC overworks, it consumes more energy, raising your electricity bills.
Also, dirty air filters allow impurities in the system, which decreases the system's efficiency. One of the ways to ensure your AC is operating optimally is to replace the air filters. New air filters allow a smooth airflow into the system, improving efficiency. As your AC doesn't need to overwork, the power consumption lowers to reduce your utility bills.
Frequent Allergies
The air filters offer you protection against airborne impurities and allergens. When clogged, air filters allow allergens and other contaminants to enter the AC and circulate throughout your home. When you breathe such air, you may suffer allergies and respiratory diseases. These symptoms are worse for allergic individuals and those with preexisting conditions such as asthma.
If your household is suffering from constant allergies or respiratory diseases, check the air filters. Replacing the air filters can improve your indoor air quality and impact your health positively. When you breathe clean air, allergy attacks in your home will decrease.
AC Unit Is Overheating
Besides dirty coils and low refrigerant, AC overheating can also result from dirty air filters. When the air filter is clogged with dirt, debris, and other impurities, the AC has to overwork to blow air throughout your home. As the components work harder, the system will overheat. Overheating accelerates the wearing down of AC parts, causing frequent repairs and eventually untimely replacement of the components or the entire unit.
If you've noticed the back of your AC unit is hot, the air filter could be dirty and need a replacement. By changing the air filter, you lessen the load on AC and alleviate overheating. Also, an air filter swap can help prevent breakdowns and prolong the lifespan of your unit.
Dusty AC Components
One of the obvious signs you need to change your AC is when you notice dust on condenser coils, vents, or filters. Dusty components indicate dust particles are finding their way into the unit. The components are less efficient, and they wear and tear quickly. Also, if surfaces in your home become dusty after wiping them down, the air filter could be the problem.
Change your air filter if your AC components or home is dusty. Also, contact a reputable HVAC contractor to clean your unit after you replace the air filter.
Changing your air filters can offer economic and health benefits. If you've noticed any of the above signs or it's been a long time since you last changed the air filters, replace them today. Contact Briarwood Heating & Cooling if you need professional HVAC service.
