I am a skilled professional who works for Summers Quality Services. I recently completed a job installing four new indoor air handler units, connecting refrigerant lines, wiring, and duckwork to all four units. This involved removing the old units, installing the new ones, and ensuring that all connections were tight and secure. I also had to perform some ductwork and insulation work to improve the efficiency of the heating and cooling system. The job required careful planning and attention to detail to ensure that everything was done correctly and safely.
