Avery Heating & Air Conditioning | Certified HVAC Repair in Houston, TX

In Houston's heat, a failing capacitor often causes your AC unit to struggle. Common signs include the outdoor unit humming but not starting, random system shutdowns, or a noticeable delay when the system turns on. If you hear clicking sounds or your AC isn't blowing cold air, it's time to call us for a diagnostic. Replacing a faulty capacitor promptly can prevent a complete system failure during a heatwave.

An improperly sized system is a major issue here. An oversized unit will short-cycle—turning on and off too frequently—which doesn't properly dehumidify our humid air, leading to a cold but clammy home and higher energy bills. An undersized unit runs constantly, straining to keep up and driving up costs. We perform precise Manual J load calculations to ensure your new system is correctly sized for your home's square footage, insulation, and Houston's climate, guaranteeing efficiency and comfort.

Proactive maintenance is key. We recommend biannual tune-ups—once before summer and once before winter. This includes cleaning coils, checking refrigerant levels, inspecting electrical components like capacitors, and ensuring proper airflow. This routine service helps catch small issues before they become major repairs, improves efficiency to combat high energy bills, and extends the life of your system against our demanding weather conditions.
