Your air handler is the indoor component of your HVAC system, responsible for circulating conditioned air throughout your home. It houses the blower motor that moves air through ductwork, the evaporator coil that cools and dehumidifies air in summer, and connects to your filter that removes particles from your air supply. When your air handler isn't working properly, your entire heating and cooling system is compromised.
Grande Air Solutions provides comprehensive air handler services for homeowners throughout Pflugerville, Austin, Round Rock, Hutto, Cedar Park, Georgetown, and surrounding communities in Travis and Williamson counties. Our licensed technicians diagnose and repair air handler problems quickly, perform maintenance that extends equipment life, and install replacement air handlers when repair is no longer cost-effective.
Founded by Isael Garcia in 2011, Grande Air Solutions has spent over 14 years servicing air handlers in Central Texas homes. We understand how critical this component is to your comfort—especially during hot Texas summers when your air conditioning runs constantly. Whether you need emergency repair for a failed blower motor, routine maintenance to prevent problems, or a complete air handler replacement, our experienced team has you covered.
Air handlers contain several critical components that work together to circulate conditioned air:
Blower Motor and Fan The blower motor powers a large fan that moves air through your duct system. Motors range from basic single-speed units to advanced variable-speed models that adjust output for optimal efficiency and comfort. Blower motor failure is one of the most common air handler problems.
Evaporator Coil The evaporator coil absorbs heat from indoor air, cooling and dehumidifying your home. It works in conjunction with your outdoor condenser unit. Dirty or frozen coils significantly reduce efficiency and can cause system failure.
Air Filter Connection Your air handler connects to the filter system at the intake. Clogged filters restrict airflow, reduce efficiency, and can damage other components. Regular filter maintenance is essential.
Drain Pan and Line As the evaporator coil cools air, it produces condensation that collects in a drain pan and exits through a drain line. Clogged drains cause water damage and can trigger system shutdowns.
Control Board The control board manages air handler operation, communicating with your thermostat and coordinating with other system components. Board failures can cause various operational problems.
Cabinet and Housing The insulated cabinet contains all components and connects to your ductwork. Proper sealing prevents conditioned air loss and maintains efficiency.
Air handlers can experience various problems that affect comfort and efficiency:
No Airflow or Weak Airflow Often caused by blower motor failure, capacitor problems, or severely clogged filters. You may notice rooms not reaching temperature or reduced air coming from vents.
Strange Noises Squealing, grinding, rattling, or banging sounds indicate mechanical problems ranging from worn belts to failing bearings to loose components.
Frozen Evaporator Coil Ice buildup on the coil is often caused by low refrigerant, restricted airflow, or dirty coils. A frozen coil can't cool effectively and may damage the compressor.
Water Leaks Clogged drain lines, cracked drain pans, or frozen coils can cause water to leak from your air handler, potentially damaging floors, ceilings, and surrounding areas.
Short Cycling The system turning on and off frequently may indicate thermostat problems, refrigerant issues, or an oversized system.
High Energy Bills Inefficient air handler operation—from dirty coils, failing motors, or poor maintenance—increases energy consumption significantly.
Musty Odors Mold growth on the evaporator coil or in the drain pan causes musty smells when the system runs. This requires cleaning and may benefit from UV light installation.

24/7 Emergency Service Available. Air handler failures during Texas heat are emergencies. We offer 24/7 emergency service to restore your comfort quickly.
How long do air handlers last? Air handlers typically last 15-20 years with proper maintenance. However, in Central Texas where systems run constantly during summer, lifespan may be shorter. Regular maintenance extends equipment life significantly.
How much does air handler replacement cost? Air handler replacement costs vary based on capacity, efficiency, and installation complexity. Basic replacements start around $2,000-$3,000, while high-efficiency variable-speed units can range from $4,000-$7,000 installed. We provide free estimates with upfront pricing.
What's the difference between an air handler and a furnace? In homes with heat pumps, the air handler contains just the blower and evaporator coil—the heat pump provides both heating and cooling. In homes with traditional AC and gas heat, a furnace contains the blower plus a gas heating section. The terms are sometimes used interchangeably but refer to different equipment configurations.
Why is my air handler leaking water? Water leaks usually indicate a clogged drain line, cracked drain pan, or frozen evaporator coil. Turn off your system to prevent water damage and call for service. We can clear drains, replace pans, and address frozen coil causes.
Should I upgrade to a variable-speed air handler? Variable-speed air handlers offer significant comfort and efficiency benefits, especially in Texas where humidity control matters. If replacing your air handler anyway, the upgrade cost often provides good value. We can explain the benefits specific to your situation.
How often should air handlers be serviced? We recommend professional maintenance at least once per year, ideally before summer cooling season. Regular maintenance includes coil cleaning, drain treatment, electrical checks, and component inspection. Homes with pets or heavy use may benefit from twice-yearly service.
Why is my air handler making noise? Noises can indicate various problems: squealing often means belt or bearing issues, rattling suggests loose components, grinding indicates motor problems, and banging may mean something is loose in the blower assembly. Don't ignore unusual sounds—they usually worsen without attention.
Can I replace just the air handler without replacing the outdoor unit? Sometimes, if the outdoor unit is in good condition and properly matched. However, mismatched indoor and outdoor components can reduce efficiency and cause problems. We'll assess your system and recommend the best approach.
