Why Is My AC Not Blowing Cold Air? 9 Causes Texas Homeowners See Most
The blower is running, air is moving, and none of it is cold. Here is how a technician narrows that down, in the order they actually check.
GUIDE/2026-05-28/TEXAS HVAC
Almost nobody publishes real HVAC pricing, which leaves homeowners guessing and makes every quote feel like it might be a rip-off. Here is how the pricing is actually built, which repairs sit at which end of the range, and where the money genuinely goes.
Most reputable companies, including ours, work on two components: a diagnostic fee and a flat-rate repair price.
The diagnostic fee covers the trip, the technician's time, and the testing required to identify the fault. It is a real cost. A truck rolling to your house carries fuel, insurance, a stocked parts inventory worth several thousand dollars, and a trained technician's hourly cost. Companies advertising a free diagnosis have folded that cost into the repair price instead, which is fine as long as you know that is what is happening.
The flat-rate repair price is quoted per job, not per hour. This protects you: if the technician takes three hours instead of one, the price does not change. It also means you approve a specific number before any work begins.
These represent the bulk of AC repair calls in Texas, and they are the reason our trucks are stocked the way they are.
| Repair | Relative cost | Typical lifespan after repair |
|---|---|---|
| Run or start capacitor | Low | 5–10 years |
| Contactor replacement | Low | 5–10 years |
| Condensate drain clearing | Low | Season to season |
| Thermostat replacement | Low | 10+ years |
| Hot surface igniter or flame sensor | Low | 3–7 years |
| Float switch replacement | Low | Many years |
These involve either a more expensive component or significantly more labor.
| Repair | Relative cost | Notes |
|---|---|---|
| Condenser fan motor | Moderate | Universal motors cost less than OEM |
| Blower motor | Moderate to high | ECM variable-speed motors cost far more than PSC |
| Control board | Moderate to high | Highly brand-dependent |
| Gas valve | Moderate | Includes combustion re-verification |
| Inducer motor | Moderate | Common on furnaces past 12 years |
| Refrigerant leak repair and recharge | Moderate to high | Depends heavily on leak location |
Evaporator coil replacement, compressor replacement, and heat exchanger replacement are the three jobs where the conversation usually shifts to whether replacement makes more sense. All three involve major components, significant labor, and often a refrigerant recovery and recharge on top.
This is the point where you should be getting both numbers in writing. Read our guide on repair versus replace before making that decision.
Three patterns account for most of the overspending we see:
Repeated refrigerant top-offs. If a company has added refrigerant to your system more than once, you are paying to fill a leaking bucket. Insist on leak detection.
Replacing symptoms instead of causes. A limit switch replaced without correcting the airflow restriction that tripped it will fail again. So will a compressor installed on a system with a lingering refrigerant leak.
Buying a system under pressure. Replacement quotes issued at 9pm during a heat wave, valid only if signed tonight, are a sales technique. A legitimate quote is still valid next week.
Ask for the diagnostic fee up front. Ask whether the fee applies toward the repair. Ask for the repair price in writing before work starts. Ask what warranty covers the part and the labor. Any company that resists those four questions is telling you something.
