Winding Resistance (Ohms)
Target: Common to Start < 3.5 Ω
We ohm out motor windings to verify insulation integrity. Direct short to ground or an open thermal overload is isolated before any replacement verdict.
We diagnose and repair residential heating, cooling, electrical, and plumbing systems without equipment sales commissions.
Physical trades demand diagnostic precision. 731 Services operates across Memphis and Jackson, Tennessee, run directly by owner-operator A.J. Eubanks since 2010. Mechanical diagnostics cost $89 to $129. We check capacitor ratings, measure circuit amperages, read refrigerant pressures, and replace failed components instead of pushing premature five-figure changeouts.

Trade diagnostics must precede parts replacement on every call.
When an air conditioner cuts out in July or a furnace refuses to ignite during a December cold snap in Shelby County, private equity rollup contractors send salesmen in uniform. Their technicians carry commission quotas. They take one look at an outdoor condenser coil with light surface oxidization and declare the entire system dead, demanding $12,000 for a replacement split system.
That is not how tradesmen work. A failed outdoor unit often comes down to a $180 dual-run capacitor that dropped below its 5% microfarad tolerance, or a $220 contactor with pitted points dropping three volts across the line. We hook up calibrated digital gauges to the Schrader ports, measure real subcooling and superheat metrics, ohm out the compressor windings, and test the start relays before drawing a single conclusion.
The same mechanical discipline governs our electrical troubleshooting, copper pipe fitting, and structural framing repairs. If a circuit breaker keeps tripping in an older East Memphis distribution panel, we run thermal scans and megohmmeter insulation tests along the branch line to isolate the exact grounded conductor before anyone suggests an unneeded service panel rebuild.
Four distinct trade divisions operated by one master craftsman.
731 Services bridges the gap between unreliable unlicensed casual labor and bloated commercial mechanical firms. Homeowners and small facility managers in Jackson and Memphis need dependable trade competence without paying for four layers of administrative overhead.
Our Heating, Ventilation, and Air Conditioning division handles complete diagnostic evaluations, contactor swaps, TXV valve replacements, blower assembly overhauls, ductwork modifications, and full heat pump changeouts. Pricing ranges from $150 to $650 for mechanical repair labor, while complete 14.3 to 18 SEER2 replacements run $6,500 to $18,000 depending on tonnage, line-set lengths, and plenum sheet metal transitions.
Our electrical division resolves breaker tripping, replaces burnt receptacles, wires dedicated equipment disconnects, and balances branch circuits. Our plumbing trade clears main-line blockages, solders rigid copper joints, fits PEX supply lines, and installs heavy-duty shutoff valves. General trade carpentry covers drywall patches, subfloor rot remediation, interior door hanging, and commercial tenant maintenance billed at our confirmed $36 to $59 per hour Memphis handyman schedule.
Mechanical diagnostic testing points on residential split systems.
Every field callout follows this physical inspection plate. We verify electrical resistance, pressure differentials, and operational safety cutoffs before quoting component repair or complete system replacement.
Schematic Plate: DX-731-M
Tolerance Check: Field Active
Location: Outdoor Condenser
Hermetic & Fan Capacitance
Tolerance: Within ±5% Rating
Capacitors degrade under hot Memphis summers. A 45/5 μF capacitor reading below 42.5 μF overheats motor windings and causes compressor lockup.
Line Voltage Drop Across Contacts
Tolerance: < 0.2 Volts AC Drop
Arcing burns silver alloy contacts. We verify 240V supply to load terminals, inspect pitted points, and confirm the 24V control coil draw.
Confirmed trade pricing schedule for Memphis and Jackson.
These are our actual operational rates. We charge for skilled diagnostic labor and verified physical trade hours. No hidden travel fees, no commission upsells, and no binding quotes without physical site testing.

Emergency After-Hours Service Protocol
Quotes depend strictly on the time of day, urgency, job type, scope of work, repair complexity, and home size. Standard work is scheduled during regular shop hours. Unscheduled night and freezing-weather calls carry our verified emergency dispatch and hourly rates to cover expedited parts access and immediate vehicle roll.
Master Craftsman A.J. Eubanks
Owner & Lead Technician • Continuous Service Since 2010731 Services was founded in Jackson, Tennessee, operating under the local 731 area code, and has expanded direct mechanical dispatching to Memphis and Shelby County. A.J. Eubanks comes from multi-generational trade roots where craft integrity outranks corporate sales targets.
Every service truck carries professional diagnostic instrumentation: Fieldpiece digital manifolds, Fluke True-RMS multimeters, calibrated micron vacuum gauges, Ridgid copper presses, and combustion test gear. When A.J. arrives at your property, you speak with the technician turning the wrenches, reading the meters, and standing behind the finished work.
We do not use sub-contracted third-party laborers for HVAC or electrical tasks. If a task falls outside our high-voltage or structural remit, we state it plainly. We do not gamble with gas heat exchangers, compromised circuit panels, or unvented plumbing lines.

Pricing Structure
Diagnostic + Labor by Estimate
The mechanical service and repair process from initial call to sign-off.
We follow four disciplined steps on every diagnostic and contracting job.
Direct Intake
Direct Tech Intake
Immediate symptom review
You speak directly with trade personnel. Describe the system noise, breaker trip behavior, or water leak. We confirm the diagnostic callout fee ($89–$129) before booking the arrival window.
Field Testing
Physical Testing
Instruments on equipment
We connect digital manifold gauges, test microfarad ratings on capacitors, check amp draw against FLA nameplates, and ohm out windings to pinpoint the failed component.
Written Estimate
Itemized Estimate
Written labor + OEM parts
We provide an itemized quote before work begins. Repair labor falls within our $150 to $650 range, or $36 to $59 per hour for standard handyman tasks. No mystery charges.
Operational Proof
Commissioning Test
Operational proof
We cycle the equipment through complete operational stages. Temperatures, operating pressures, and safety safeties are measured and logged before we collect payment.
Clear answers to trade objections and what we refuse to do.
Do you offer free diagnostic visits? No. Proper mechanical diagnostics require expensive calibrated instruments, vehicle fuel, and twenty to forty minutes of hands-on testing. Contractors offering free estimates send commission salespeople whose sole objective is selling you a $14,000 replacement. Our $89 to $129 fee protects your existing equipment from predatory sales tactics.
Do you install customer-supplied cheap internet equipment? We do not install unbranded, grey-market mini-splits or uncertified gas valves purchased online. We cannot warrant equipment whose manufacturing provenance and internal safety controls are unknown. We install OEM components and certified systems from established distributors.
Who is 731 Services not for? If you want the lowest-bid unlicensed Craigslist handyman who works without multimeters or permits, we are not the right fit. If you want a corporate conglomerate with glossy brochures and twenty-person call centers, call a national franchise. If you want an experienced craftsman who fixes the problem right the first time, call A.J. Eubanks.
