Air Handler Repair in Lewisville, TX
The air handler is the indoor half of your split system — it contains the blower motor, evaporator coil, and controls that move air across the cooling surface and into your ducts. When it fails, the outdoor unit may run fine but your home gets no airflow or no cooling. Most air handler problems involve the blower motor, capacitor, control board, or coil.

When to Call
When You Need Air Handler Repair
- The outdoor unit runs but you feel no air coming from the vents
- Your air handler makes a loud humming sound but the blower does not spin
- You smell a burning odor coming from the supply vents when the system runs
- The blower runs constantly and will not shut off even when the thermostat is satisfied
- Water is pooling around your indoor unit or the secondary drain pan is full
- You replaced the filter recently but airflow still feels weak at every register
How It Works
Our Process for Air Handler Repair
- 1
Access and Initial Check
We open the air handler cabinet and check for obvious signs of failure — a seized blower wheel, burnt wiring, a flooded drain pan, or a frozen coil. We document what we find before touching anything.
- 2
Electrical and Motor Testing
We test the blower motor winding resistance, check the run capacitor, and verify control board outputs. A weak capacitor often causes the motor to hum without spinning. We test before assuming.
- 3
Drain and Coil Inspection
We check the evaporator coil for ice, dirt buildup, or corrosion. We inspect the condensate drain line for blockages, which are a frequent cause of water overflow shutdowns on Lewisville installations.
- 4
Fault Confirmation and Estimate
We tell you what failed and what needs to happen to fix it. If a blower motor needs replacement, we confirm parts availability before quoting. Some ECM motors on newer systems require ordering.
- 5
Repair Execution
We complete the repair, whether that is a capacitor swap, blower motor replacement, drain flush, or control board swap. We do not guess and replace parts speculatively.
- 6
Airflow and Temperature Verification
After the repair, we run the full system and check static pressure, blower speed operation, and supply air temperature. We confirm normal operation before leaving the job.
What's included
- Full inspection of the blower motor, capacitor, coil, and control board
- Labor to replace the confirmed failed component during the same visit if parts are on hand
- Condensate drain line flush and inspection as part of the air handler check
- System airflow and cooling performance verification after the repair
- Condition report on the evaporator coil and drain pan
What's not included
- Evaporator coil replacement if the coil is leaking refrigerant — that requires a separate repair estimate and refrigerant recovery
- Ductwork repairs if poor airflow is traced to duct leaks rather than the air handler itself
- Thermostat or smart control upgrades if the existing control is functional — that is a separate conversation
Real Situations
Common Scenarios in Lewisville
A homeowner in Lakeland Hills has an air handler in the attic that stopped blowing air during a 100-degree week, and the thermostat shows the system is calling for cooling.
We access the attic unit and find the blower capacitor has failed — the motor hums but cannot start. We replace the capacitor, test motor amperage to confirm it has not been damaged from repeated hard starts, and verify airflow before leaving.
A homeowner near Lewisville Lake finds water on the floor below their air handler closet and shuts the system off, worried about ceiling damage.
We find the primary condensate drain is blocked with algae, which is common in humid North Texas summers. We clear the drain line, flush it, check the float safety switch, and confirm the secondary pan drain is clear. We also check whether any ceiling damage warrants a closer look.
A homeowner in Valley Vista notices a burning smell from the vents shortly after the system starts each time, and the smell fades after a few minutes.
We inspect the blower motor and find the windings are beginning to overheat from a failing bearing. Intermittent burning smell that fades is a known pattern for a motor in early failure. We replace the motor before it fails completely and confirm the replacement motor runs at correct amperage.
Lewisville Context
Why this matters in Lewisville
A large share of Lewisville homes have air handlers installed in attic spaces, which means the units operate in ambient temperatures that can exceed 130 degrees in July and August. That heat accelerates wear on blower motors and capacitors faster than closet or basement installations. Homes built in the late 1990s and early 2000s in areas like Timber Creek and Valley Ridge frequently have original air handlers that are now at or past typical service life, and repairs on those units sometimes surface secondary issues.
Straight Talk
About pricing & scope
Air handler repair costs vary based on which component failed and whether it is a standard PSC motor or a variable-speed ECM motor. ECM motors are more expensive and sometimes require a few days to source. Control board replacements also depend heavily on the equipment brand and age. We confirm parts and cost before proceeding — we do not order parts without your approval.
