AC Not Cooling Repair in Plano, TX

An AC that runs constantly but can't cool your home is one of the most common calls we get in summer. The system isn't broken in an obvious way — it's just losing the fight against heat load. Causes range from low refrigerant and dirty coils to an oversized home addition that the original system was never designed to handle. We don't guess. We measure refrigerant levels, airflow, and outdoor unit performance before recommending anything.

When to Call

When You Need AC Not Cooling Repair

  • Your thermostat is set to 74 but the house sits at 82 all afternoon no matter what
  • The outdoor unit runs nonstop from noon to midnight during a Plano heat wave
  • You had the system serviced recently but it still can't keep up on days above 100 degrees
  • Your system cools fine at night but falls behind badly once the sun hits your west-facing windows

How It Works

Our Process for AC Not Cooling Repair

  1. 1

    Temperature Differential Check

    We measure supply and return air temperatures to determine whether the system is actually producing adequate cooling or simply failing to distribute it.

  2. 2

    Refrigerant Pressure Evaluation

    We check operating pressures against manufacturer specs for current outdoor temperature to identify low charge or overcharge conditions.

  3. 3

    Coil and Condenser Inspection

    We inspect the evaporator coil for dirt or ice and check the condenser coil and fan for blockage, damage, or restricted airflow from debris.

  4. 4

    Capacity vs. Load Assessment

    If the equipment checks out mechanically, we evaluate whether the home's actual heat load — from insulation, windows, or added square footage — exceeds what the system can deliver.

Plano Context

Why this matters in Plano

West-facing homes in newer Plano developments near the Dallas North Tollway deal with intense afternoon solar gain that challenges even properly sized systems. On days over 103, most residential AC is designed to maintain a 20-degree indoor-outdoor split — not achieve 72 degrees regardless of conditions.

Straight Talk

About pricing & scope

Repair cost depends heavily on what the diagnosis reveals. A refrigerant recharge is different in scope from a failed compressor or a system that's simply undersized for a home that was expanded after original installation.
