Filters may not seem that important to most property owners. You just change them once in a while, and your furnace is good to go, right? However, this approach to furnace maintenance paves a path for an overworked furnace, constant repairs, and eventual failures.
Can a dirty filter stop a furnace from working? When we provide HVAC repair services in Bowie, Maryland, our team at S&L Air Conditioning and Heating often finds that old filters cause multiple problems. Learn more about why a clean filter is essential to your furnace’s functions below.
The Purpose of a Furnace Filter
Your return vent houses the furnace filter, which should cover the entire vent opening. Most filters have a MERV rating that determines their effectiveness. Choosing the correct rating for your furnace system and home needs will protect your indoor air quality and HVAC system.
Improve Indoor Air Quality
Numerous allergens, microbes, and dirt particles populate your home’s atmosphere. Even if you dust and clean religiously, you still breathe in airborne particulates that could irritate your sinuses or make you feel unwell. A fresh filter will eliminate those particulates when the air passes through the return vent.
Protect Your Duct Network and HVAC System
Your furnace filter doesn’t just serve you and your family. It also protects your furnace.
As the particulates circulate throughout your duct network, they eventually make it to the heating unit. The debris gradually coats some components and becomes sucked inside of others, decreasing your furnace’s lifespan.
Can a Dirty Filter Stop a Furnace From Working?
Even when you purchase an energy-efficient residential furnace for your home, you must still stick to maintenance basics to ensure your HVAC works correctly. Clogged air filters cause expensive, inconvenient problems, including:
- Reduced heating efficiency: A dirty filter forces your furnace to work much harder than it otherwise would. An overworked system leads to furnace overheating, increased energy consumption, and higher utility bills.
- Component failure: When a furnace overheats, it stresses numerous internal components. An old filter could even trigger problems that cause safety features to react and stop the heating cycles.
- Airflow restrictions: You might notice that your vents don’t produce as much warm air as they used to. The restricted airflow can prevent your home from reaching an ideal, maintainable temperature.
- Increased repairs and shorter lifespan: Restricted airflow, triggered safety features, and overworked components collectively influence your furnace’s lifespan. You’ll need more professional repair services and impromptu system replacements.
Can a dirty filter stop a furnace from working? It absolutely can. Not only that, but it can significantly harm your finances and eat away at your time.
How To Tell When You Need a New Filter
If you forget to change your filter within the three-month minimum, you aren’t alone! In fact, your filter’s mileage may vary depending on your indoor environment. Check out these tell-tale indicators of a dirty filter to better gauge when to change it.
Uneven or Weak Heating
Restricted airflow prevents heated air from flowing at full force. Rooms further away from the return vent may feel chillier than usual. You might also feel a persistent chill throughout your whole home.
Higher Utility Bills
Running your furnace under normal circumstances can cost lots of money. When it operates with a filthy filter, it requires more resources than usual, which means your utility costs will noticeably spike.
Low Air Quality
Since air filters impact indoor air quality, they also impact your wellness. You might exhibit mild symptoms like:
- Coughing and sneezing
- Watery, itchy eyes
- Runny nose
- Throat irritation
These symptoms are common during cold or allergy season. However, you’ll experience them beyond those circumstances when your filter can’t remove allergenic particulates.
Dingy Filter
When you collectively notice these issues, open your return vent and check your furnace filter. Does it have a dingy yellow or brown color? If so, you should replace it.
