Air Handler Service in Houston, TX
The air handler is the indoor half of your system, and when it struggles, the whole house feels it. We diagnose and repair air handler problems that leave rooms warm or airflow weak.
Your air handler holds the blower motor, the evaporator coil, and the electrical controls that move conditioned air through the house. In most Houston homes it lives in a hot attic or a closet, and that heat plus year-round runtime is hard on the motor and the board. When it acts up you'll notice weak airflow, warm rooms, strange noises, or a system that runs but never cools.
Blower problems are common. A failing blower motor, a bad capacitor, or a worn wheel packed with dust and buildup all cut airflow, which makes the whole system less effective and can freeze the coil. We test the motor and capacitor under load and clean or replace the blower assembly so the system moves the air it's supposed to.
The evaporator coil inside the air handler is where humidity gets pulled out of your air, and in our climate it works overtime. That coil also generates a lot of condensate, so a clogged drain line or a stuck float switch can shut the system down or, worse, overflow the pan and stain your ceiling. We flush the drain, test the safety switch, and check the coil for dirt and leaks.
We also go through the electrical side, the control board, sequencers, and wiring, since attic heat and storm-season power surges take a toll on those components. Getting the air handler right is what turns cold air at the coil into even, comfortable cooling in every room.

Frequently asked questions
What are signs my air handler is failing?
Weak airflow from the vents, warm rooms even when the AC is running, rattling or grinding noises, or water around the indoor unit. Any of those point to the blower, coil, drain, or controls in the air handler.
Why is water leaking from my indoor unit?
It's almost always the condensate drain or the drain pan. In our humidity, the line clogs with algae and backs up. We flush the drain, test the float switch, and check the pan so it doesn't overflow into your ceiling.
Can a bad air handler make my whole system underperform?
Absolutely. The outdoor unit can be working perfectly, but if the blower or coil in the air handler is restricted, airflow drops and the system can't deliver cool air evenly. It's often the hidden cause of a house that won't cool.
My air handler is in the attic, is that a problem?
It's common in Houston, but attic heat is hard on the motor and electronics, and a drain overflow up there can damage your ceiling. That's why we pay close attention to the drain, float switch, and pan on attic units.
