Spring is a season for spring cleaning, and that means you may be giving your HVAC system a little TLC. If you pull out the air filter and find that it’s black, you need to do a little digging. Here’s what a black air filter means, and what you can do about it.
It can be surprising to pull out your air filter, only to find that it’s turned a strange shade of black, but this simply means that the filter has done its job. The filter is designed to trap particles, including dust, allergens, and pet dander, as they travel through your home’s air. As those particles build up, the color of the filter changes. Sometimes this happens more quickly when there is a lot of mold or moisture in the air or if the home has high amounts of allergens and particles in the air. It can also happen if the filter’s been in use for over a month.
If your air filter is black, then you need to replace it. Once the air filter is full of particles and its color changes, then the HVAC system’s efficiency will be compromised. When the filter is full of gunk, air can’t flow through the system as it should. This makes the system work harder, increases your energy bills, and increases wear and tear on your home’s home comfort systems.
The challenge for homeowners is knowing when to change the filters. The fact is that each home is going to have a different time frame for filter replacement, but a good rule of thumb is to replace the filters every one to three months. If you’re noticing that the filter is black when you do change it, consider pushing up the changing timeline so you start changing it before it turns black. You may also want to consider air duct cleaning to get some of the debris out of your ductwork.
Most of the time black air filters mean you need to replace the filter, and nothing more. That said, if your filters are turning black very quickly, then you may have a mold problem. Mold puts your family’s health and safety at risk, and it needs to be addressed immediately by a qualified HVAC technician. Give the Signature team a call to discuss the likelihood that you have a mold problem right away. We offer a number of air purification and dehumidification services that can help protect your home’s air quality and your family’s safety.
For most homeowners, black air filters aren’t a cause for panic. They simply mean that you need to increase the frequency that you change your air filters, and that the filter is doing its job. If you have questions or concerns about your air filters and your home’s indoor air quality, we’re here to help.

"Bob Seeger was our technician this time around. His level of professionalism was exceptional - it really stood out! Overall we are very happy that we switched to Signature several years ago!"-Mark Kenney
"The Signature techs who come out to our house are always top-notch professionals. Very courteous, careful, and thorough. They always provide great explanations of the work that they are doing. I never feel like I am being pressured into unnecessary work or equipment replacement (like I used to feel with Service Experts). Today, Wade was the tech who came out. He was here exactly on time at 8am, and was done within an hour. Great work and another great service experience from Signature! Update 9/27/2016 - Today Bob Seeger came out to service our system in preparation for the winter. I was extremely impressed by his professionalism and courtesy. Before he started, we sat down and he clearly explained what he would be doing as part of the maintenance, and we agreed upon the need to replace the filter on the main unit, and also to perform humidifier maintenance as part of the work. After the work was complete he made recommendations for overall system enhancements that we should consider. Signature really has top-notch people working for them, and I continue to be extremely happy that we switched over to them several years ago."-Mark Kenney
"Bob Seeger was our person to service our furnace and water heater. He showed me a problem with our water heater that could have been a major problem. He was very honest, great and so efficient! He fixed the problem. I am kind of hoping he will be the one to work with in the spring."-Debbie Kaba
"Always feel confident with the work performed by Danny from Signature."-William Stolting
"Bob was quite knowledgeable of the type of geothermal system that I have in my house. Before completing the annual maintenance/tune-up that I had requested, he asked relevant questions about my geothermal system (e.g., date of installation, last service, temperature preference, electric usage, etc.). After inspecting and servicing my system, Bob explain service that my system needed now and recommendations that would benefit my system. He explained the options in a non-pressured approach, as well as, the benefit in joining Signature HVAC's service plan which was helpful. Throughout the service visit, Bob was courteous, friendly and respectful. My wife and I were very satisfied and we plan to continue to use Signature HVAC in the future."-John Schmitt

"Daniel Cross (Signature) completed a thorough and quick fall service on my heating systems. What I liked best about Danny is that he spoke to me as a knowledgeable customer rather than treating me like a clueless homeowner. So refreshing to be treated with respect by an HVAC provider! He had an opportunity to "upsell" me on a service, but was honest and told me that it wasn't valuable in my situation. I would certainly trust him to service my equipment again, and would definitely recommend him to a friend."-Susan Wentz
"Thanks again for walking me through the process and pointing out what was going on in my system. Mold be gone! Professional and friendly service. Thanks for your help."-Mia Bosna
