Living in Houston means dealing with more than just the scorching summer heat—it also means making sure your home's HVAC system can keep up. With extreme temperatures, high humidity, and unpredictable weather shifts, your HVAC system works hard year-round.

    1. Poor Airflow

    Restricted airflow is one of the most common HVAC Houston issues. It can result from clogged filters, dirty ducts, or malfunctioning fans. Poor airflow strains your system, leading to higher energy bills and uneven cooling.

    Solution: Our technicians inspect and clean ducts, replace filters, and ensure all components are working efficiently. Regular AC maintenance from Champion and Nash keeps your airflow consistent and strong.

    2. Thermostat Issues

    Faulty thermostats lead to inconsistent temperatures and higher energy usage. Whether it's outdated, incorrectly programmed, or completely malfunctioning, it affects the whole system.

    Solution: Champion and Nash can upgrade your thermostat to a smart model, reprogram an existing one, or replace a faulty unit to improve control and comfort.

    3. Refrigerant Leaks

    Refrigerant is essential for cooling. A leak can lead to poor performance, higher bills, and damage to the compressor.

    Solution: Our certified HVAC Houston team will detect and repair refrigerant leaks, recharge the system, and ensure it's sealed properly to avoid repeat issues.

    4. Dirty or Clogged Filters

    Houston's air can carry pollen, dust, and pollution. A dirty filter reduces system efficiency and indoor air quality.

    Solution: We recommend changing filters monthly during heavy use and offer professional tune-ups that include full filter checks and replacements.

    5. Frozen Evaporator Coils

    Evaporator coils can freeze due to poor airflow, dirty filters, or low refrigerant levels. This leads to reduced cooling capacity and potential system breakdowns.

    Solution: Champion and Nash technicians will diagnose the root cause, defrost the coils, and fix airflow or refrigerant issues.

    6. Dirty Condenser Coils

    The outdoor condenser coil is exposed to the elements. Dirt buildup prevents heat from escaping, reducing cooling performance.

    Solution: We offer regular maintenance that includes power-washing and inspecting the condenser unit, ensuring efficient performance year-round.

    7. Noisy HVAC Units

    If your HVAC Houston system is making banging, squealing, or grinding noises, it's likely a mechanical issue such as a loose belt, worn motor, or failing compressor.

    Solution: Our technicians will inspect the unit, identify the source of the noise, and make the necessary repairs to prevent further damage.

    8. High Humidity Indoors

    Houston is known for its humidity. An HVAC system that doesn’t regulate moisture well can leave your home feeling sticky and uncomfortable.

    Solution: Champion and Nash offers HVAC upgrades and dehumidification solutions to maintain balanced indoor humidity levels.

    9. Uneven Cooling

    If some rooms feel cooler or warmer than others, you could have an issue with ductwork, zoning, or thermostat placement.

    Solution: We perform comprehensive inspections and may recommend duct sealing, zoning solutions, or improved insulation.

    10. System Short Cycling

    Short cycling means your system turns on and off frequently. This can be caused by oversized systems, thermostat malfunctions, or airflow problems.

    Solution: Champion and Nash will determine the cause of the short cycling and recommend a fix, whether it’s a component replacement or system recalibration.
