Completed routine maintenance on residential HVAC system today. Changed dirty air filter and cleaned both evaporator and condenser coils. Checked refrigerant levels and electrical connections - all within specifications. Lubricated blower motor bearings and inspected ductwork for any issues. System tested perfectly with good airflow and temperature differential. Customer signed maintenance agreement for bi-annual service. Unit should run efficiently all season long.

Service was done in an orderly way. Solved the leak problem. Was not to interested in other questions I had about some other plumbing issues.
Had Klaus and Sons replace my washer cold and hot water valve box that included the drain. When I installed my washer, it overflowed. They came back the next day, snaked the drain and everything is all good. The didn't charge me for snaking the line. Thank you for the great service.
