Heating and Cooling Richmond

Completed commercial HVAC installation involving removal and recycling of existing evaporator coil and condensing unit. Flushed and pressure-tested existing refrigerant line set to ensure integrity. Installed new Goodman cased evaporator coil requiring modification of supply collar and return ductwork to accommodate 4" height increase. Modified gas line and PVC venting system, incorporating 2" to 3" PVC transitions with 45-degree elbows to clear new coil configuration. Installed new condensing unit on equipment pad while retaining existing painted electrical disconnect. Verified proper refrigerant charge and system operation using digital manifold gauges, confirming appropriate superheat and subcooling values. Programmed thermostat and tested complete system operation through multiple heating and cooling cycles to ensure proper functionality and customer comfort.

Completed full HVAC system installation including a 90,000 BTU furnace with left-side configuration and 2.5 ton air conditioning unit in residential utility space. Installed new thermostat and reconnected existing humidifier (AprilAire unit with digital control) to new system. All ductwork connections secured with proper sealing, mechanical and electrical permits obtained, and system tested for proper operation upon completion.

Responded to service call for non-functional air conditioning system with no cooling and inoperative outdoor fan unit. Upon arrival, assessed 23-year-old AC system located on side of residence. Conducted comprehensive evaluation of outdoor condensing unit and indoor components to determine system condition and failure points. Documented existing equipment configuration including exposed ductwork, copper refrigerant lines, and electrical connections in basement utility area. Provided detailed estimate for complete HVAC system replacement due to age of equipment and extent of failure, explaining options and recommendations for new installation to restore cooling capacity to the residence.

Responded to no cooling call on 23-year-old air conditioning system with non-operational outdoor unit and condenser fan failure. Upon inspection, diagnosed failed condenser fan motor and assessed overall system condition, noting significant age-related wear on components including weathered refrigerant lines, oxidized mounting hardware, and deteriorated electrical connections. Advised customer that due to the system's age exceeding typical equipment lifespan and the extent of component degradation, replacement of the entire unit would be more cost-effective than repair, as additional failures are imminent given the advanced age of the equipment.

Responded to callback for condensate drain pan sensor continuously detecting moisture despite no visible water present after previous reset. Inspected evaporator coil assembly and drain pan components, noting moisture accumulation on copper refrigerant lines and surrounding metal components. TXV replacement part ordered and available at shop for follow-up installation to address underlying cooling performance issue causing unit to blow only slightly cool air.

Responded to no cooling complaint on residential air conditioning system less than one year old. Upon arrival, inspected outdoor condenser unit and found system operational but delivering insufficient cooling. Performed diagnostic evaluation of refrigerant levels, electrical components, and airflow to identify cause of reduced cooling capacity and address customer concerns regarding air circulation.
