Breathe Easy: Why It’s Important To Change Your Air Filter

Did you know that Americans spend 90% of their life indoors where air pollutants are 2 to 5 times higher than the outdoors (according to a recent study with the EPA)? Air filters act as your home’s first line of defense against harmful particles and debris. A clogged or dirty filter can harm the quality of the air you breathe and can cause extensive damage to your HVAC system, affecting your health and your wallet!

Here’s a few reasons why you should change your air filter regularly:

Keep your home clean! Your air filter traps a wide range of contaminants such as dust, mites, pollen, mold, bacteria, animal hair and dander, and more. When your air filter is dirty, all of these particles are floating through the air in your home.

It’s good for your health! Poor air quality can lead to allergic reactions, aggravated asthma, airborne sickness, and harmful irritation of your eyes, throat, mouth and skin.

Lower energy bills! When your air filter is dirty and clogged your HVAC system has to work overtime, whether heating or air conditioning. This leads to higher energy usage which results in higher electricity bills!

FUN FACT: You can save as much as 7.5% on your electricity bill when your HVAC is working with a clean air filter!

It’s eco-friendly! Clean air filter = efficient HVAC = less energy usage = happy planet 🌍

Avoid HVAC system damage! Dirt and neglect are among the leading causes of HVAC system failures. Checking and changing your air filters regularly can increase the longevity of your system and prevent extensive system damage.

What kind of air filter should you get?

Air filters come in different shapes and sizes (and colors), but the most important thing to note when selecting your filter is the MERV rating. Minimum Efficiency Reporting Value (MERV) is a standard that rates the overall effectiveness of air filters. A higher value MERV rating equates to a finer filtration, meaning fewer particles and airborne contaminants can pass through the filter.

Most HVAC systems have a recommended filter for ultimate efficiency. Your LimRic HVAC technician is your expert source on choosing the right air filter for your HVAC system. Just make sure you get the right size!

How often should you change your air filter?

It depends on the quality of air filter you have. But as a general rule of thumb, you should change your air filter at least every 90 days if you live in a home without pets and every 60 days if you live in a home with pets or have allergies.

PRO TIP: You might need to change your air filter more frequently during peak summer and winter seasons. When the temperatures are extremely hot or cold, your HVAC is running more often which means it is filtering more air through your home, causing your filter to get clogged quicker.

The good news is that changing your air filter is extremely easy, and that the LimRic Plumbing, Heating & Air experts are always on call, ready to fix any heating and air conditioning issue that may arise.

Why HVAC Maintenance Is Mandatory


Just like most things in your home, your air conditioning unit needs regular maintenance and checkups to keep it running smoothly. We’ve created a list of three easy-to-do tips for homeowners to maintain their HVAC units over the years.

  1. Replace your filter. One of the simplest of tasks in HVAC maintenance is changing out the filters, but many homeowners simply forget to do so. Depending on your home and lifestyle, your filter should be replaced every one to three months. Not sure how often to replace your filter? Ask a professional, who can evaluate your home’s specific needs based on size, occupants, pets, smoking habits, and more.
  2. Check the unit fan. Before you power on your AC unit each spring, take a moment to check the fan. The fan mounted on top of the outside condenser should be inspected every so often for cracks and chips on the blades.
  3. Clean around the unit. Bushes can begin to branch out too close to the unit or grass can grow into the machine, affecting the amount of air it is able to intake. Keeping the area around an outdoor unit well-manicured is key.
  4. Schedule a checkup. At least once each year, homeowners should hire a professional to inspect and perform preventative maintenance on an HVAC unit. This works to identify and address issues before they become a problem (like losing heat on Charleston’s one snow day).

The Importance Of Good Air Quality

Your health starts at home! The air you breathe in can help predict your health and could even make you sick if certain precautions are not taken. Here at LimRic Plumbing, Heating & Air, we have a wonderful team of professionals who are able to help you improve your overall air quality.

Without proper air quality in your home, you and your family can get really sick. Indoor pollution tends to lurk near heating and cooling systems the most. Your air conditioning system can often leave traces of water in the ducts and creates the perfect breeding ground for mold and bacteria. This can cause asthma, allergies, coughing, and headaches. Mold and bacteria growth can be prevented by having your ducts cleaned regularly by a professional.

Toxins can be found in your furniture, cleaners, and even your toiletries. Several services are offered by our team of experts such as air cleansers, humidifiers, ventilators, and UV lamps to all help enhance your indoor air quality for you and your family.
