A.J. Eubanks operates direct mechanical and general trades without sales commissions.
Founded in 2010 under the local Jackson 731 area code and expanded to our direct Memphis base on Sea Horse Dr, 731 Services delivers multi-generational craftsmanship in HVAC, electrical, plumbing, and structural carpentry. You work directly with the licensed contractor turning the wrenches.
Trade background, regional roots, and owner-operator identity.
731 Services is an independent residential and commercial contracting firm owned and operated by A.J. Eubanks. The enterprise was founded in 2010 in Jackson, Tennessee, operating with pride under the historic 731 regional telephone prefix that spans West Tennessee. As our client base grew throughout Madison and Shelby counties, we established our direct dispatched workshop hub at 5271 Sea Horse Dr, Memphis, TN 38141-0581.
Most trade operations in the Mid-South today have been acquired by private equity consolidators. These firms replace seasoned master craftsmen with call center dispatchers and commissioned salespeople disguised as technicians. At 731 Services, we intentionally rejected that corporate path. A.J. Eubanks personally answers diagnostic inquiries, arrives on the job site in fully equipped trucks, hooks up the digital manifold gauges, ohms out the electrical coils, and carries out the actual physical repairs.
Our legal trade registration in Jackson and our direct workshop footprint in Memphis allow us to serve homeowners, property managers, and small commercial facilities with immediate technical accountability. When you hire 731 Services, you deal with a master tradesman who puts his name and reputation on every soldered copper joint and every HVAC commissioning record.
Specific core trades, failure diagnostics, and material standards.
731 Services focuses strictly on four mechanical and structural trade divisions where verifiable craftsmanship directly impacts building longevity and occupant safety:
1. HVAC Diagnostics, Repair & Replacement: Diagnostic callouts are billed at a flat $89 to $129. We check capacitor microfarad ratings within plus-or-minus 5% tolerance, measure subcooling and superheat using digital manifold instruments, calculate temperature differential (16°F to 21°F Delta-T across evaporator coils), and inspect heat exchangers for microscopic stress fractures. Mechanical component repair labor ranges between $150 and $650. Complete split and package system replacements range from $6,500 to $18,000, covering full EPA refrigerant recovery, custom sheet metal plenum transitions, copper line set flushing, and digital thermostat integration. Emergency after-hours callouts run $100 to $350, with emergency labor billed at $70 to $400 per hour.
2. Electrical Troubleshooting & Panel Maintenance: We troubleshoot tripped breakers, isolate neutral-ground faults, correct corroded branch pigtails, replace thermal-magnetic breakers, install dedicated equipment circuits with 12/2 and 10/2 Romex, and bring older residential load centers up to modern National Electrical Code standards.
3. Plumbing Repairs & Fixture Restoration: We replace leaking shut-off valves with brass quarter-turn ball valves, sweat Type L copper water tubing with lead-free solder, install PEX-A expansion lines, clear localized drain obstructions, rebuild shower cartridges, and install residential water heaters.
4. Remodeling & General Structural Trades: We handle framing remediation, subfloor rot replacement, drywall taping and feathering to Level 4 smooth finish, door hung plumb to within 1/16-inch tolerance, and general facility maintenance. Standard scheduled trade work is billed at $36 to $59 per hour in Memphis; emergency trade calls are billed at $65 to $95 per hour.
Physical trade tooling and testing equipment inventory.
A tradesman is only as accurate as his measuring instruments. We do not guess at electrical loads or refrigerant saturation temperatures; our service vehicle carries professional-grade calibration tools.
Digital Refrigerant Manifolds
Simultaneous real-time superheat, subcooling, vapor saturation, and micron vacuum pull-down measurement down to 250 microns.
Electrical Diagnostic Meters
True RMS microamp flame sensor verification, capacitance testing, inrush current monitoring, and continuity checks across circuit boards.
Infrared & Boroscope Optics
Visual internal inspection of gas furnace heat exchangers, crawlspace moisture tracing, and electrical panel thermal hot-spot detection.
Refrigerant Recovery & Vacuum
EPA Section 608 certified rapid recovery, dual-stage deep evacuation pumps, and nitrogen pressure testing manifolds up to 450 psi.
Pipe Sweating & Pressing
Swirl combustion tips for lead-free copper soldering, high-temp silver brazing on line sets, and commercial mechanical press fittings.
Carpentry & Laser Alignment
Self-leveling 360-degree layout lines for framing, stud sistering, subfloor leveling, and dead-straight miter trim cuts.
Direct contractor access and field communication protocol.

Principal Mechanical & General Contractor"I built 731 Services on one rule: tell the homeowner the mechanical truth. If an outdoor fan motor has a blown $18 capacitor, we swap the capacitor and test the motor amp draw. We do not frighten clients into buying a $12,000 unit when their existing equipment has years of serviceable life. When a replacement is genuinely necessary, we lay out the options, calculate the load correctly, install it to code, and warranty our labor."
