An air handler typically looks like a large metal box or cabinet, usually rectangular, that contains the blower motor, evaporator coil, and air filter. It is connected to your ductwork and is often located in a basement, attic, garage, or utility closet, depending on the home’s layout.
An air handler is one of the main components of your HVAC system, and at first glance, it usually looks like a plain metal box or cabinet. Most air handlers are rectangular and range in size from a large suitcase to a tall appliance, depending on the system and the size of the home. Inside the cabinet are key parts like the blower motor, evaporator coil, and air filter, all of which work together to circulate conditioned air throughout your home.
In many Denver-area homes, air handlers are commonly found in basements, utility rooms, attics, garages, or interior closets. Newer homes may have more compact, vertically mounted units, while older systems are often larger and easier to spot. You may also notice insulated ductwork connected to the unit, along with electrical wiring and a condensate drain line.
If you’re unsure whether you’ve found your air handler, or if the unit looks rusted, noisy, or oversized for the space, it may be a sign that it needs professional attention. For homeowners across the Denver metro area, including those in southern Denver with easy access from Aurora, Done! Plumbing, Heating, Cooling & Electric can help identify your air handler, inspect its condition, and recommend repair or replacement options when needed.
In many homes, the air handler is installed in the attic to keep ductwork centralized and out of living spaces. Other homes may have air handlers in basements, garages, or dedicated utility closets where there is enough space for the equipment and access for service.
The location of an air handler depends on factors like home size, climate, available space, and how the duct system was designed. Some systems are placed to reduce noise, while others are positioned for easier airflow or maintenance access.
Knowing where your air handler is located helps with filter changes, routine maintenance, and identifying potential issues such as airflow restrictions or moisture concerns. If access is difficult or the location is unclear, a professional inspection ensures the system can be serviced safely and operates as intended.
Done! can help locate your air handler, inspect its condition, and confirm it is working efficiently as part of routine AC service or maintenance.
If coils are visibly dusty, start by turning off power to the system. After removing the access panel, loose debris can be gently brushed away using a soft brush or manufacturer-approved coil cleaner. Care must be taken to avoid bending fins, damaging wiring, or forcing debris deeper into the unit.
Evaporator coils sit deep inside the air handler, and surface cleaning often doesn’t address buildup between fins or underlying airflow issues. DIY cleaning can also miss problems like restricted drainage, hidden corrosion, or refrigerant-related concerns that affect performance.
Professional air handler maintenance includes thorough coil cleaning, airflow testing, and system inspection to ensure efficiency and safe operation. This level of service helps restore proper cooling, reduce system strain, and prevent long-term damage caused by dirty or restricted coils.
Done! provides professional air handler maintenance to fully clean coils, restore airflow, and protect overall system efficiency.ly clean coils, restore airflow, and protect your system’s efficiency.
An AHU typically contains key components such as the blower motor, evaporator coils, air filter, and controls. Together, these parts circulate air, support cooling performance, and help maintain indoor air quality by filtering and conditioning the air before it reaches living spaces.
The air handling unit works with the outdoor AC unit to deliver cooled air throughout the home. If the AHU is not functioning properly, issues like weak airflow, uneven temperatures, or reduced efficiency can occur even if the outdoor unit is running.
Problems such as unusual noises, poor airflow, moisture issues, or inconsistent cooling often point to an issue within the air handler. Professional inspection and maintenance help ensure the AHU is operating safely, efficiently, and in coordination with the rest of the system.
Done! provides diagnostics, maintenance, and repairs for air handling units to restore proper airflow and reliable cooling performance.
