The Importance of Good Furnace Filters

As mentioned above, your filter is essential to your heating and cooling equipment. It protects it. Therefore, it needs to be changed relatively frequently. For 1-inch filters, once a month or every two months is recommended. Thicker filters might get by with half the number of changes.

You’d be surprised how often we’re called out for Carol Stream or Bloomingdale for a ac repair only to find out the issue is a clogged filter. Changing yours regularly helps avoid awkward situations like this, saving you service fees. We know it can be hard to justify buying something you throw in the trash. And the idea of paying more for a higher-end, thicker one can feel foolish.

But rest assured, you’ll more than get your money out of the investment. The benefits of installing a high-end filter include:

  • Lowered amounts of dust
  • Fewer changeouts
  • Less dog and pet danger clogging up the air
  • Enhanced HVAC system efficiency
  • Smoother equipment operation

Always forget this vital part of Carol Stream AC or furnace maintenance? Then, you might want to consider signing up for our tune-up program. That way, you’re sure your system is clean at least once or twice a year.

What Should You Look for in a Carol Stream Furnace Filter

Though we might recommend installing an electric static or a 6-inch filter, that’s not feasible for every homeowner in Bloomingdale or Glendale heights.

Still, there are some items to look out for when shopping for a filter. First, don’t grab one you can see through. While those $0.99 blue ones might be tempting, they don’t provide much protection. When it comes to this purchase, you truly get what you pay for. Though, for most households, a middling option is often adequate.

You should also check the filter's MERV rating. Anything below 13 is subpar and not recommended.

You’ll also want to buy something the same size as yours. Get out a ruler and measure. Lastly, read the information on the back of the packaging. Some brands are designed to catch pet dander, while others are engineered to help those with seasonal allergies.

The Other Types of HVAC Filters

When most people think of HVAC filters, they think of pleated fibrous paper held snug by a cardboard frame. Others might conjure images of simple fiberglass ones. Though the most common, this isn’t the only option. Below are a few other ways you can filter your air:

  • HEPA Filters: These specialized furnace filters are hard to beat in terms of efficiency. They trap over 99.9% of contaminants in the air, including bacteria and smoke particles. They are often found in medical facilities and recommended to individuals with respiratory problems.
  • UV Light Filters: These use ultraviolet light to kill viruses and bacteria in your home. They’re also great at removing mold spores. It should be noted, however, that the lights do little against pollutants like dust, fumes, and smoke. For that reason, they’re often paired with a HEPA filter. Installing this type of air filtration system can be expensive.
  • Electrostatic Filters: These filters create static electricity using paper and cotton fibers. The static acts as a magnet, trapping contaminants in the screen. Because they keep these items from spreading, they’re a great choice for people with allergies. To further enhance their efficiency, a carbon filter can be added. For a higher upfront cost, a reusable one can be purchased. However, compared to HEPA filters, they struggle to trap large particles like dust and mold.
  • Media Filters: Boosting high surface areas, this air filter is up to seven times more efficient than your standard pleated one. Though packed into a 6-inch space, the unfurled fabric can measure over 75 feet long. This grants them a heightened lifespan and works great for individuals in industrial zones or with weak immune systems.

Of course, if you’re after germ protection, you might want to consider installing a full-on air filtration system in Carol Stream.

Cost-Effective and Fast Furnace Replacement
Excellent experience with Gray's. They provided a very competitive quote to replace my furnace, and once I gave them the go-ahead, they had a technician on site within 15 minutes—that level of responsiveness is rare. The team was professional, efficient, and easy to work with throughout the process. Highly recommend Gray's for anyone looking for fast, reliable, and fairly priced HVAC service.

I’ve had the pleasure of working with Gray's both personally and professionally. They’ve handled my regular furnace and AC maintenance for many years, always to my satisfaction. When it came time to replace my furnace, their expertise with our complex setup made it an easy decision to trust them with such a significant investment. Professionally, the company I work for also relies on Gray's to provide reliable and cost-efficient service to nearly 200 condo associations across the Chicagoland area. Their staff is friendly, knowledgeable, helpful, and patient — truly a pleasure to work with.
Jacqulin Goodlove-Schroeder
World-Class Furnace and Heat Pump Installation
My experience with Gray's was world class. From the initial estimate walk through in my home, to the installation of my new heat pump and furnace, the experience was pleasant the whole way through. The entire process with Gray's was efficient and effective, just like our new HVAC system. They've found the perfect combination of new school technology and old school relationship building. I feel like I'm in the right hands going forward!
Drew Doster
Friendly Late-Night HVAC Service
Gray's, thank you for sending Anthony to us. It was a late night emergency call. He was very friendly, courteous, knowledgeable and extremely professional. We will definitely keep your company in mind should we need any additional service. Thank you!
Hector R O
Respectful, Informative, and Fast AC Repair
We had Gray's come out to see why our AC unit wasn’t cooling correctly. They were able to come out right away, then figured out we had a small leak. We were given options by the tech that made me feel like I wasn’t being forced into a decision I didn’t want to make like I’ve felt from other companies. I wasn’t being talked into buying a whole new system, which was very important to me. Kirby was able to fix everything up that day and we had cold AC in under 3 hours. The office staff were easy to deal with. I also spoke to the owner, Dan, when he followed up with me and he was super friendly and professional.
Jonelle Salinas
Efficient AC Repair and Helpful Maintenance Tips
I recently had Sergio and Eric come over to update our AC unit for the summer, and I couldn't be more pleased with their service. From the moment they arrived, their professionalism was evident. They thoroughly inspected our unit and quickly diagnosed the issue causing it to shut off unexpectedly. Not only did they fix the problem efficiently, but they also provided us with excellent recommendations to prevent future issues. Their expertise and friendly demeanor made the entire experience seamless. I highly recommend Sergio and Eric for anyone in need of AC maintenance or repairs.
Marcus Howard
Effective Heat Exchanger Cleaning Fixed Furnace Fast in Sub-Zero Weather
We were in desperate need of help. Our furnace had stopped working and the sub-freezing temps were expected to drop to zero. Panic was setting in. But, Gray's was able to send their skilled technician, Sergio, who arrived almost two hours ahead of schedule. Sergio, diligently and expertly examined the furnace. Eventually, he diagnosed that a very dirty heat exchanger was causing poor airflow causing the system to shut down. He then spent a considerable amount of time in a very cramped space cleaning the suspect part. Eventually, he emerged, dirt smudged on his face with a bag filled with dirt. The system restarted and we are not in danger of suffering from hypothermia.
