5 Star HVAC Contractor in Elkton, MD

Installed a new furnace/air handler and connected it to the existing galvanized supply plenum and ductwork, sealing seams at the cabinet and plenum transitions. Connected the refrigerant lines to the outdoor condenser and used a digital manifold and vacuum gauge to evacuate the system and verify a deep vacuum before opening the refrigerant charge.

Returned to complete the air handler service and installed new UV germicidal lamps in the cabinet, replacing the previous units. Inspected the evaporator coil and drain pan area, noting residue on the pan surface, and verified condensate drain line and insulated refrigerant lines were intact. Secured the access panel and confirmed the system was ready for operation.

Performed preventative maintenance on a Bradford White electric water heater, inspecting the tank, soldered copper supply and outlet piping, brass shutoff valves, and the thermal expansion tank for leaks, corrosion, and damage. Verified pipe insulation and electrical connections were secure and found no signs of rust, leakage, or deterioration, leaving the unit in good operating condition.

Performed a comfort call inspection of the 150-amp main electrical breaker panel, verifying the main disconnect, double-pole breakers for the dryer and range/oven, and branch circuits for the garage, washer, and pump. Noted mixed-brand breakers in the lower-left positions and minor surface wear, with no damage or operational faults identified. Also inspected the living area, including the ceiling fan and wall-mounted window air conditioner, and found no visible damage or anomalies.

Returned to inspect the HVAC unit's low-voltage control wiring and terminal block connections. Verified and secured conductor terminations at terminals 1, 2, and 3, confirmed wire nut splices were tight, and rerouted and secured the wire harness near the control board and sensor. Noted oxidation on the copper refrigerant line set and confirmed the foam insulation and mounting bracket were properly seated.

Verified the outdoor condenser unit was level using a torpedo level and confirmed the cabinet, louvered panels, and fan guard were clean and free of frost, rust, or damage. Inspected the adjacent vent pipe base plate and surrounding grade, noting dust and debris on the pipe and vegetation growth around the base, with no structural concerns identified.

Installed a new gas furnace and air handler unit in the utility space, including connection of the gas supply line, PVC combustion venting, and PVC condensate drain routed to a condensate pump. Completed line-voltage and low-voltage thermostat wiring with pressure switch connections secured, and mounted the electrical disconnect and control panel. Unit is fully assembled, with all seams sealed and no visible damage, leaks, or corrosion.

Inspected and serviced the hydronic heating system, including the brass pressure-reducing valve assembly, isolation ball valve, and associated copper piping and fittings, confirming no active leaks and noting oxidation and patina at the joints. Verified boiler temperature and pressure gauge operation and checked the drain valve and surrounding piping to ensure the system is operating within normal parameters.

Performed a system rejuvenation inspection on the HVAC air handler, verifying the evaporator coil section, drain pan, and cabinet insulation were in serviceable condition with no evidence of frost, rust, or leaks. Confirmed the drain pan was clean and dry, noted the unit's A2L refrigerant safety labeling, and documented a supply duct temperature reading of approximately 69.4°F using a digital pocket thermometer. Observed light dust accumulation on the coil fins and minor wear on the foil-faced insulation and duct wrap, with no immediate corrective action required.

Performed a duct cleaning estimate, inspecting the upright furnace/air handler cabinet and finding dust and grime buildup on the return grille slats along with soiled lower access panel vents. Also evaluated the exterior Lennox condenser unit, noting weathered housing and leaf debris at the fan grille, and recommended debris removal and clearing of surrounding vegetation to maintain proper airflow and system efficiency.
