Our maintenance service is a thorough check-up designed to keep your system running efficiently and catch small issues before they become big problems. For Houston homeowners, this includes inspecting and cleaning key components, checking refrigerant levels, testing system controls and safety devices, and ensuring proper airflow.

Regular maintenance can improve energy efficiency, extend your system's lifespan, and help prevent inconvenient breakdowns during our hot summers.

An improperly sized system is a common issue that leads to discomfort, high energy bills, and premature wear. A unit that's too large will short-cycle, failing to properly dehumidify your air—a major concern in Houston's humid climate. One that's too small will struggle to keep up during heat waves. Our technicians perform a detailed Manual J load calculation, which factors in your home's square footage, insulation, window placement, and local weather data. This scientific approach ensures we recommend a system with the precise capacity to keep your home comfortable and energy-efficient year-round.

Yes, that's a distinct possibility. The air handler is the indoor component that circulates conditioned air through your ducts. Common issues we see in Houston homes include a clogged air filter restricting airflow, a dirty blower wheel, or a failing blower motor. These problems reduce cooling efficiency and can strain the entire system. Our repair service includes a comprehensive diagnosis of both indoor and outdoor units. We'll check the air handler's components, electrical connections, and drain line—which is especially prone to algae growth in our humidity—to identify and resolve the root cause of your cooling issue.
