How do you know when your AC filter needs to be replaced?

Did you know that the quality of the air in your home can have a huge impact on your physical health? If you’re suffering from unexplained headaches, dizziness, fatigue, or irritation of your eyes, nose, and throat, your dirty air filter could be to blame!  

A dirty or clogged air filter is often a source of indoor air quality problems. The good news is, it’s very easy to fix. The hardest part seems to be remembering to do it.

Creating a seasonal home maintenance checklist and changing your filter on a schedule is a great idea. However, if that’s not your style, then you’ll want to make sure you know how to recognize that it’s time to change out your filter. Start with these signs:

The Air Conditioning Unit is Too Hot

One clear sign that your AC filter needs replacing is when the back of the unit is too hot. If the filter is very dirty, you may even feel warm air coming out of the back of the unit. A clogged filter forces the air conditioner to work harder to keep the house cool. This will lead to more frequent AC repairs and, ultimately, shorten the lifespan of the unit. Lessen the load by simply changing the AC filter regularly.

The Air Isn’t Cold Enough

You can attribute reduced HVAC efficiency to various problems. If you notice that your air conditioner isn’t cooling as it normally does or is blowing warm air, the first thing you should check is the AC filter. A dirty air filter won’t allow that refreshing cool air to properly pass through it, leaving you sitting in a pool of unpleasant sweat. If, however, the air filter is not the problem, an experienced HVAC service technician should investigate the problem and perform the required maintenance.

The Electricity Bill Has Increased

When the electricity bill starts to creep higher, it can sometimes be difficult to determine the cause. It could be a faulty appliance or a poorly functioning AC system. In Texas, we expect higher electric bills during the summer months because we rely so heavily on air conditioning when the heat strikes. However, if your electric bill is higher than normal, the culprit could be a dirty air filter. This is why preventative HVAC maintenance is so important. Keeping your HVAC system well-maintained helps it operate more efficiently. As a result, it lowers your energy bill.

You’re Suffering More Allergy Attacks

Allergy sufferers should be particularly diligent when it comes to changing air filters. Dust pollen, and pet dander cling to the air filter. When the filter becomes saturated with such pollutants, they’ll get blown out and circulated in the air throughout your home. As a result, you’ll suffer the misery of allergy attacks more frequently.Your home’s air conditioner can either impact your health positively or negatively. Use the AC system to improve your home’s indoor air quality rather than worsen it. Keep the AC filter clean, and consider adding an air purifier. You should soon notice a decrease in symptoms.

There’s More Dust Near the Air Vents

Another common sign of a dirty air filter is finding dust on surfaces and furniture near the vents. Compare these surfaces to other surfaces farther away. If the surfaces nearest the vents are dustier while others appear cleaner, it’s a sure sign that your air filter needs replacing.The AC filter is not the most complicated part of an air conditioning system, yet it can drastically affect its efficiency and the air quality in your home. Avoid these problems by remembering to check and replace your AC filters regularly.
