5 Star HVAC Contractor in Elkton, MD

Performed recall service on the refrigerant system's liquid line filter drier, inspecting the wall-mounted assembly including the red-capped canister, brass flare fittings, copper line set, and shutoff valve. Verified the unit label and part number against recall criteria and confirmed all connections were intact, with no evidence of leaks, frost, or ice. Documented the installation with photos for service records.

Responded to a callback and inspected the attic-mounted air handler, including the blower housing, electrical access panel and flexible conduit connection, condensate drain piping, and foil-faced duct insulation. Confirmed wiring was secured and the cabinet and blower assembly showed no visible rust, frost, or damage, and noted staining on adjacent insulation for monitoring.

Performed a video pipe inspection using a RALCAM inspection camera, which revealed heavy scale buildup and rust/mineral staining along the interior pipe walls. Inspected the gas furnace with the access panel removed, evaluating the inducer blower assembly, gas valve and brass gas piping, pressure switches and tubing, wiring harness routing, and PVC vent connections. Noted minor surface corrosion on the gas pipe fittings and an LP conversion label on the flexible gas line.

Responded to recall and inspected the attic-installed air handler, identifying active seepage and corrosion at the galvanized threaded pipe fittings, with evidence of moisture and blue-green residue on the adjacent insulated line and PVC fitting. Cleaned and dried the affected area, verified the condensate drain pan, drain line, and gas line connections were intact, and confirmed no leaks or additional moisture remained at the unit.

Performed a video borescope inspection of the ductwork, documenting heavy rust, corrosion, and buildup along the interior surfaces. Inspected the A-frame evaporator coil, finding dust accumulation and discoloration on the fins and tubing, and checked the condensate drain line and refrigerant line connections at the air handler. Documented all findings for system rejuvenation and cleaning.

Commissioned a new furnace/air handler installation, verifying electrical and gas connections and securing control compartment wiring. Performed amperage draw checks with a true-RMS clamp meter, measuring 4.2 A on the monitored circuit during operation and 0.2 A at idle, confirming current draw within expected range and normal system startup.

Performed a comfort call inspection of the residential split system, evaluating the outdoor condenser unit and indoor air handler components. Noted dense vegetation growth around the condenser base restricting airflow and recommended clearing the surrounding clearance, and observed a small tear in the insulated duct section along with staining and discoloration on the PVC condensate drain piping at the joints, indicating possible moisture or residue buildup that should be monitored or repaired.

Performed a comfort call inspection of the attic-mounted air handler and evaporator coil, noting heavy dust and debris accumulation on the coil fin surface and discolored residue on the foil-faced insulation near the unit, with the primary drain pan and condensate tubing checked for proper condition. Inspected the electrical disconnect and breaker panel serving the system, confirming clean, undamaged components with no signs of corrosion, overheating, or frost, and verified the refrigerant line set and wiring connections were secure.

Installed a new upright gas furnace in the utility alcove, connecting the flexible gas line to the gas control valve and completing the wiring and cabinet panel assembly. Verified secure gas and electrical connections and confirmed proper unit operation, with the work performed in a heavily soiled compartment showing signs of prior water or flood damage.

Performed electrical diagnostics on the outdoor condensing unit and the associated electrical panel using a clamp multimeter. Measured voltage at the breaker and contactor terminals and checked amperage draw at the condenser to verify electrical supply and component operation. No visible damage, frost, or corrosion was found on the unit.
