HVAC Repair Rowlett TX | Call Block Air Conditioning and Heating

A freezing evaporator coil is often caused by restricted airflow from a dirty filter, low refrigerant levels, or a failing blower motor. These issues are common in our climate. Our technicians perform a comprehensive diagnosis to identify the root cause—like checking for leaks or cleaning the coil—to prevent future freeze-ups and restore efficient cooling.

Uneven cooling is a frequent challenge in larger Rowlett homes. Solutions can include installing a zoning system with multiple thermostats, balancing your ductwork to improve airflow distribution, or adding a supplemental ductless mini-split for hot spots. We assess your home's layout and current system to recommend the most effective and energy-efficient fix.

We recommend professional HVAC maintenance twice a year—once in spring for your AC and once in fall for your heater. This routine service is crucial in our Texas climate to catch small issues like dirty coils or refrigerant leaks before they lead to major breakdowns, ensuring reliable performance and lower energy bills year-round.
