Top-Rated HVAC Repair in Middleborough, MA 02346 - A1 HVAC Plus

Common signs include uneven heating or cooling between rooms, higher-than-normal energy bills, excessive dust, and your HVAC system running constantly. Our technicians use specialized tools like blower door tests and duct pressure testing to accurately locate and measure leaks in your home's ductwork, a frequent issue in our area.

In our New England winters, frequent culprits are a dirty or faulty flame sensor, a worn-out hot surface ignitor, or issues with the gas valve or control board. We start with a thorough inspection, clean critical components, and test the ignition sequence to identify the exact failure point, getting your heat restored safely and efficiently.

Our process begins with a comprehensive duct inspection using cameras and diagnostic equipment. We then seal leaks at joints, seams, and connections using professional-grade mastic sealants or metal-backed tapes. After sealing, we test the system again to confirm improved airflow and efficiency, which can significantly boost comfort and lower heating costs in our climate.
