    Understanding the Problem

    When your HVAC system can't keep up with Houston's heat, every room feels uncomfortable. If your thermostat reads 80°F but you've set it to 72°F, your system is struggling. This could be a simple fix or a sign that your system needs professional attention.

    Common Causes

    Undersized System

    If your HVAC was improperly sized for your home, it will never adequately cool during peak heat. This is especially common after home additions or renovations.

    Aging Equipment

    AC systems lose 5-10% efficiency per year after age 10. A 15-year-old system may only deliver 60% of its original cooling capacity.

    Ductwork Problems

    Leaky, disconnected, or poorly insulated ducts in your attic (where temps exceed 140°F) can waste 20-30% of your cooled air.

    Dirty System Components

    Dirty coils, clogged filters, and blocked condensers force your system to work harder while delivering less cooling.

    Insufficient Insulation

    Poor attic insulation allows heat to radiate into your home faster than your AC can remove it.

    When to Call a Pro

    If your system runs constantly but can't reach the set temperature — especially when it's above 95°F outside — call Big League Air for a professional assessment.
