Expert Air Handler Service in Nashville
Air handlers are central to commercial HVAC systems, moving conditioned air through ductwork to occupied spaces throughout your building. Whether your facility uses chilled water air handlers, DX air handlers, or fan coil units, these machines require regular professional service to maintain airflow, efficiency, and indoor air quality.
Harpeth Air provides comprehensive air handler service across Nashville including routine maintenance, repair, component replacement, and complete overhauls. Our technicians are experienced with all types of commercial air handling equipment from small fan coil units to large built-up air handlers with multiple sections and complex controls.
Air handler problems often manifest as comfort complaints in the spaces they serve. Hot or cold spots, humidity issues, poor air quality, and excessive noise frequently trace back to air handler issues. Our systematic approach identifies the root cause of these problems and implements effective solutions.
Air Handler Services
Coil Cleaning & Replacement
We clean heating and cooling coils using chemical cleaning agents and pressure washing to restore full heat transfer capacity. When coils are too damaged or corroded for cleaning, we replace them with new coils matched to the air handler specifications.
Motor & Drive Service
Fan motor replacement, bearing service, belt alignment and replacement, sheave adjustment, and VFD installation and service. We ensure your air handler delivers the design airflow at the proper static pressure with minimum energy consumption.
Filter Programs
We provide scheduled filter replacement programs using the appropriate filter type and efficiency rating for your air handler and application. Proper filtration protects coils, maintains air quality, and supports occupant health. We stock common commercial filter sizes and special order specialty filters as needed.
Complete Overhauls
For aging air handlers that are still structurally sound, a complete overhaul including new coils, motors, bearings, dampers, and controls can restore like-new performance at a fraction of replacement cost. We evaluate each unit and provide honest recommendations about overhaul versus replacement.
Our approach to air handler service
Air handlers are the interface between your HVAC system and the people in your building. When they perform well, occupants are comfortable and energy costs are reasonable. When they perform poorly, you get complaints, high utility bills, and indoor air quality problems. Our air handler service ensures your units perform at their best.
We take a whole-system approach to air handler service, considering not just the unit itself but the ductwork it serves, the controls that operate it, and the source equipment (chiller, boiler, or DX system) that provides heating and cooling capacity. This integrated perspective allows us to identify and solve problems that a component-level approach would miss.
Frequently Asked Questions
What does air handler maintenance include?
Our air handler maintenance includes filter replacement, coil inspection and cleaning, belt inspection and replacement, motor bearing lubrication, electrical connection inspection, drain pan and condensate drain cleaning, damper operation verification, and operational testing. We document all findings and provide condition assessments with each visit.
How often should air handler coils be cleaned?
Cooling coils should be inspected at least twice per year and cleaned as needed, typically at least once annually. Nashville pollen, dust, and humidity can accelerate coil fouling. Dirty coils reduce airflow, decrease capacity, increase energy consumption, and can promote microbial growth. Regular coil cleaning is one of the most impactful maintenance tasks for air handler performance.
Can you retrofit my air handler with variable speed drives?
Yes. Adding variable frequency drives (VFDs) to air handler fan motors is one of the most cost-effective energy efficiency upgrades available. VFDs allow fan speed to match actual demand rather than running at full speed constantly. Energy savings of 30-50% on fan energy are typical, with payback periods of 1-3 years depending on the application.
