How Dirty Air Filters Can Lead to Costly HVAC Repairs in Garrett, IN Homes
Did you know that your AC air filters can make or break your HVAC system’s efficiency and lifespan? Neglecting this simple part can lead to expensive repairs, higher energy bills, and even total system breakdowns.
T&T Plumbing & Heating, Inc. has seen firsthand how something as basic as a dirty filter can cause major problems. Our HVAC contractors explain why AC air filters are so important, how Garrett’s local air quality plays a role, and what happens when you don’t change your air filter as often as you should.
Garrett, IN’s Local Air Quality and Your AC Air Filters
Living in Garrett means enjoying a blend of rural charm and small-town community, but it also means dealing with a variety of airborne contaminants that can impact your heating and cooling system’s HVAC filter.
- Seasonal Pollen: In the spring and early summer, tree and grass pollen levels can soar, making allergies worse and clogging filters faster.
- Harvest Dust: Fall harvest season often kicks up dust from surrounding farmland, which can quickly settle into your AC air filters.
- Household Dust and Airborne Particles: Carpet fibers, pet dander, dust mites, and dust from normal daily activities build up on your home air filter.
- Humidity-Related Particles: Our humid summers can promote mold and mildew growth in ductwork if airflow is compromised.
For maintaining indoor air quality, homeowners in Garrett often need to replace AC air filters more frequently than the generic “every 90 days” guideline suggests due to these factors.
The Connection Between Healthy Air Filters and a Healthy HVAC System
Think of your AC air filter as a protection system for your heating and cooling system. By removing dust, pollen, and other particles from the air before they enter the system, the filter helps protect sensitive components from damage.
A clean filter keeps airflow steady and prevents unnecessary strain on the blower and compressor so the HVAC system runs efficiently. Regularly replacing the home air filter can extend your system’s lifespan by several years, saving you thousands in replacement costs.
What Happens When You Neglect Your AC Air Filters
Skipping filter changes might seem harmless, but over time, the impact can be severe. Here’s what can happen:
1. Reduced Airflow and Strain on the System
When your AC air filter is clogged, air struggles to pass through. Your HVAC system has to work harder to pull air, which strains the blower motor and other components. Over time, this extra workload can lead to premature breakdowns.
2. Higher Energy Bills
A dirty filter makes your system less efficient, meaning it must run longer to achieve the same temperature. That extra run time translates directly into higher utility costs.
3. Poor Indoor Air Quality
Once your AC air filter becomes saturated with dirt, pollen, and dust, it can no longer effectively trap particles. This allows contaminants to circulate throughout your home, aggravating allergies, asthma, and other respiratory issues.
4. Frozen Evaporator Coils
A clogged filter reduces the amount of warm air reaching the evaporator coil, which can cause it to freeze. This not only stops your system from cooling effectively but can also lead to water damage when the ice melts.
5. Overheated System Components
Poor airflow can cause certain parts of your system to overheat, triggering safety shut-offs and damaging components.
How a Dirty Air Filter Can Turn into a Big Repair Bill
At T&T Plumbing & Heating, Inc., we’ve seen homeowners face major furnace repair or air conditioning repair costs that could have been avoided with regular AC air filter changes.
- Blower Motor Replacement: When airflow is restricted for too long, motors can burn out, costing hundreds of dollars to replace.
- Compressor Failure: If a dirty filter leads to frozen coils and refrigerant issues, your compressor—the most expensive part of your system—can be damaged.
- Overheated Heat Exchanger: In heating mode, poor airflow can cause the heat exchanger to overheat and crack. This is not only an expensive repair but also a serious safety concern due to the risk of carbon monoxide leaks.
- Burned-Out Capacitors: Longer run times put extra demand on start and run capacitors, which can fail and stop your system from starting altogether.
- Fan Blade Damage: When airflow is compromised, the system may develop imbalances that put stress on fan blades, bending or breaking them over time.
- Refrigerant Leaks: Ice buildup from reduced airflow can crack coils or loosen fittings, leading to refrigerant leaks that require both repair and recharge service.
Replacing an AC air filter is a small investment compared to these costly repairs.
How Often Should Garrett Homeowners Replace AC Air Filters?
While general guidelines suggest changing AC air filters every 90 days, local conditions in Garrett often require a more frequent schedule:
- Every 30 days during high-pollen seasons or if you have pets.
- Every 45–60 days during average conditions.
- Monthly checks if your home is near farmland, a busy road, or undergoing remodeling projects.
When to change your air filter depends on your area and the conditions unique to your home. T&T Plumbing & Heating, Inc. recommends checking your current air filter monthly and replacing it whenever you see visible dust buildup.
If you also use a whole-home air purifier, remember that those filters need regular attention too. Many air purifier filters require replacement every 3–6 months, depending on usage, filter type, and local air quality. Neglecting an air purifier filter can reduce its ability to remove allergens, dust, and other airborne particles, meaning your AC air filter will have to work harder and your indoor air quality could suffer.
Tips for Choosing the Right AC Air Filter
Not all residential air filters are created equal. While there are tons of standard air filters available at the local hardware store, not all are the right air filter for your HVAC equipment. When selecting a replacement filter, consider:
- MERV Rating: MERV stands for Minimum Efficiency Reporting Value. This indicates the filter’s ability to trap dust and other particles. For most Garrett homes, a MERV rating of 8–11 is sufficient to catch dust, pollen, and pet dander without over-restricting airflow.
- Material: Pleated air filters typically trap more contaminants than traditional fiberglass filters.
- Size: Always check your system’s specifications to find the right size air filter. Standard air filters are available in many sizes, and custom air filters can be obtained for non-standard systems.
Choosing the right furnace filter and AC filter can help improve indoor air quality as well as heating and central air system performance.
Preventive Maintenance: The Best Way to Avoid Costly Repairs
Changing your AC air filter is just one part of a larger preventive maintenance strategy. Pairing regular filter changes with seasonal tune ups can:
- Improve energy efficiency.
- Reduce the risk of emergency breakdowns.
- Extend the lifespan of your HVAC system.
- Maintain healthy indoor air quality.
