Aci Service-Air Conditioning & Heating Service - Brownsville's Trusted HVAC Repair

This common issue, known as uneven cooling, often stems from improper airflow balance or inadequate duct sizing for your home's layout. Our technicians perform a detailed system evaluation, checking ductwork, insulation, and your unit's capacity. We then implement solutions like adjusting dampers, adding zoning systems, or recommending duct modifications to ensure consistent comfort throughout every level of your home.

Intermittent power or error codes at your thermostat are frequently caused by wiring problems, a faulty transformer, or a tripped safety switch in your HVAC system. Our experts safely diagnose the electrical issue, whether it's a loose connection at the thermostat, a problem in the furnace control board, or a safety lockout, and perform the necessary repair to restore reliable control of your heating and cooling.

If your system is running but not cooling properly, it could be due to a refrigerant leak, a dirty evaporator coil, or a failing compressor. We recommend turning the system off to prevent further damage and calling us immediately. Our technicians will perform a comprehensive diagnostic to identify the specific issue—whether it's a simple fix like cleaning coils or a more complex repair—and get your cool air flowing efficiently again.
