When you invest in a whole-home media air cleaner, you are upgrading the respiratory system of your house. Unlike portable units that only scrub the air in a single room, our installation integrates directly into your central heating and cooling system. This ensures that every time your system runs, the entire volume of air in your home is filtered multiple times per hour. The service we provide focuses on a complete retrofit of your return air drop to accommodate high-efficiency filtration cabinets.
The core of this service involves replacing the standard, ineffective one-inch filter slot with a dedicated media cabinet. This cabinet houses a thick, deep-pleated filter—typically four to five inches wide—that offers significantly more surface area than standard filters. This increased surface area allows for higher filtration efficiency (MERV rating) without choking the airflow to your furnace or air handler. Restricted airflow is a primary cause of equipment failure, so our installation prioritizes balancing high capture rates with optimal static pressure.
Included in the installation is the necessary sheet metal fabrication to ensure a seamless fit. A media air cleaner must be airtight; if air can bypass the filter, the efficiency of the system drops dramatically. We seal all connections between the new cabinet, the return drop, and the furnace unit. This prevents unfiltered air from entering the blower compartment and ensures that 100% of the air passing through the system is treated.
We also verify the compatibility of the new filtration system with your existing blower motor. Not all HVAC systems can handle high-restriction filters. We assess your current equipment to select a media cabinet that improves air quality without straining the motor, which could otherwise lead to premature system failure or increased energy bills.

Installing a media air cleaner is a precise technical task that requires knowledge of airflow dynamics and ductwork fabrication. We follow a strict protocol to ensure the unit performs effectively from day one.
The process begins with a thorough evaluation of your current HVAC system in Franklin. We measure the physical space available near the furnace or air handler and calculate the required airflow (CFM) for your specific equipment. This allows us to select a media cabinet that fits the space and matches the blower’s capacity.
To install the larger media cabinet, we often need to modify the existing return air drop. We carefully cut and remove the section of the ductwork where the old filter rack was located. This step requires precision to ensure the structural integrity of the return drop is maintained.
We position the new media cabinet between the return duct and the furnace. The unit is leveled and secured mechanically. Once in place, we apply mastic sealant or high-grade aluminum tape to all seams and joints. This airtight seal is critical; it forces all air to pass through the filter media rather than leaking around it.
We insert the high-efficiency media filter into the cabinet. We check the access door mechanism to ensure it creates a tight seal when closed but remains easy for the homeowner to open for future filter changes. Ease of maintenance is a key factor in long-term performance.
After the physical installation is complete, we run the HVAC system to test the airflow. We measure the static pressure drop across the new filter to confirm it falls within the manufacturer’s specifications. This ensures your heating and cooling system continues to operate efficiently.
Homeowners often wonder if they should simply stick with their current setup, repair an old electronic air cleaner, or upgrade to a modern media cabinet. The decision usually comes down to efficiency, maintenance, and reliability.
Most homes are equipped with a one-inch filter slot. These thin filters are designed primarily to protect the equipment from large debris, not to clean the air you breathe. To capture smaller particles like mold spores or fine dust, a one-inch filter must be very dense, which rapidly restricts airflow and can damage your furnace. Upgrading to a media air cleaner allows for high-efficiency filtration without the airflow restriction, offering a superior solution that standard filters cannot match.
In the past, electronic air cleaners (precipitators) were popular. However, these units act as "zappers" that require frequent cleaning of metal collection plates. As the plates get dirty, the efficiency drops to near zero. Furthermore, the power supplies in these units often fail, leaving you with an expensive, non-functional box. Converting an old electronic cleaner to a modern media cabinet is often more cost-effective than repairing the electronics. Media cleaners have no moving parts, require no electricity to filter, and maintain their efficiency as they load with dust.
If you are tired of monthly filter changes, a media air cleaner is the right choice. Because of the deep pleats and massive surface area, these filters typically only need to be replaced once every 6 to 12 months, depending on household conditions. This extended lifespan reduces the hassle of maintenance while providing consistent protection throughout the year.
If you have recently upgraded to a high-efficiency furnace or air conditioner, protecting that investment is vital. Dust buildup on the blower wheel or evaporator coil significantly reduces efficiency and shortens equipment life. A media air cleaner provides the best level of protection for these sensitive components, making it a financially sound decision for long-term equipment health.
Operating HVAC equipment in Franklin requires attention to specific regional climate challenges. The humid subtropical climate means summers are hot and heavy with moisture, while winters can drop well below freezing. This variability impacts how we approach indoor air quality and installation standards.
In our region, humidity control is essential. During the summer, high moisture levels create an ideal environment for mold and mildew growth within ductwork and on evaporator coils. A media air cleaner captures mold spores before they can settle and multiply in the system. However, the installation must be executed perfectly. If the return air drop is not sealed correctly during installation, humid attic or crawlspace air can be drawn into the system, bypassing the filter and adding latent heat load to the home. Our installation process focuses heavily on airtight sealing to prevent this "infiltration," which is a common issue in local homes.
Franklin is surrounded by agricultural activity and lush vegetation. This results in distinct allergy seasons. Spring brings heavy tree pollen, while late summer and harvest season kick up ragweed and dust. A standard filter is often overwhelmed by these seasonal spikes. The media air cleaners we install are rated to handle these heavy particulate loads without clogging immediately. We advise clients on the optimal times to check their filters based on these local seasonal patterns to ensure uninterrupted protection.
While media air cleaners are passive devices, modifying the ductwork to accommodate them falls under mechanical work that must adhere to local building codes. We ensure that the return air drop modifications maintain the required cross-sectional area for airflow as dictated by Kentucky mechanical codes. Improperly sizing a return drop during this modification can starve the system of air, leading to code violations and system inefficiency. We handle all compliance aspects, ensuring your system meets safety and performance standards.
Achieving true indoor air quality requires more than just buying a product off a shelf; it requires a holistic understanding of how air moves through a home. Our approach goes beyond the simple insertion of a box. We analyze the entire ventilation system to ensure that the addition of a media cleaner enhances, rather than hinders, the performance of your heating and cooling equipment.
We prioritize technical accuracy. From measuring static pressure to fabricating custom sheet metal transitions, every step is performed by trained professionals who understand the physics of airflow. We do not use "one-size-fits-all" solutions. If your ductwork requires a specific transition to ensure smooth airflow into the filter, we fabricate it. This attention to detail prevents turbulence and noise, common complaints with poorly installed units.
Transparency is central to our operations. We provide clear assessments of what a media air cleaner can and cannot do. We explain the MERV ratings applicable to your specific health needs—whether you are targeting virus-sized particles or general household dust. You receive a complete explanation of the installation timeline and the expected maintenance schedule before work begins — read our reviews to see what neighbors say.
