Our 8-Step Service Process - How Father and Son Diagnoses, Repairs, and Verifies

Every claim on this site - same-day, honest, fair-priced - comes down to what actually happens at your unit.

Our process · Orlando

A measured diagnosis, verified results.

This is the documented process Tony and Jon Luke Ventresca follow on AC repair, installation, and maintenance calls in Orlando: a measured diagnosis, written options, your approval, and verified results you can see.

Father and Son uses a standard 8-step service process on AC repair, installation, and maintenance calls in Orlando: (1) Same-day dispatch confirmation, (2) On-site diagnostic with calibrated instruments, (3) Honest diagnosis with the customer present, (4) Options explained with pricing transparency, (5) Customer approval before any work begins, (6) Repair or installation completed using OEM or manufacturer-approved parts when available and appropriate, (7) Operational verification (CFM, temperature differential, refrigerant subcool/superheat, humidity), (8) Documentation provided to the customer. Owner-operated by Tony and Jon Luke Ventresca. Florida CAC1823678 licensed.

The 8-Step Process

Most service calls follow the same documented sequence, whether the job is a failed capacitor in July or a full system replacement. Each step is documented so you see the work, not just the invoice.

01Step 1 of 8

Same-Day Dispatch Confirmation

When you call (407) 929-3535 during business hours, Tony or Jon Luke confirms the available scheduling window - with same-day scheduling during business hours when availability allows. You reach a real owner and get a real time, not a third-party answering service that routes the call and adds a premium.

02Step 2 of 8

Arrival and Visual Assessment

Tony or Jon Luke handles the service call or stays directly involved in the diagnosis. Before any instrument comes out, we walk the condenser, air handler, and accessible ductwork - bulged capacitor tops, an iced evaporator coil, scorched contactors, and disconnected return ducts often show themselves on sight.

03Step 3 of 8

Instrument Diagnosis

We confirm the visual read with calibrated tools: a digital manifold gauge for suction and discharge pressure, a multimeter for capacitor microfarads and compressor amperage, and a thermal camera for temperature differentials across the coil and ducts. The number on the meter names the failed part - not a guess.

04Step 4 of 8

Findings Explained With You Present

Tony or Jon Luke walks you through the readings at the unit, not from inside a truck. You see the failed capacitor's measured microfarads against its rated value, or the pressures that prove a refrigerant leak, before any price is discussed.

05Step 5 of 8

Written Options and Transparent Pricing

You get written options with up-front pricing - repair, and where the math supports it, replacement - drawn from our published Orlando ranges. No surprise add-ons and no "comfort consultant" upsell: AC replacement runs $5,800–$9,000 and duct replacement $6,000–$10,000, so you know the real numbers before you decide.

06Step 6 of 8

Your Approval Before Work Begins

Nothing gets installed or replaced until you approve the option you chose. The diagnosis comes first, the quote second, and the work third - in that order, every time.

07Step 7 of 8

Repair With OEM or Manufacturer-Approved Parts

We complete the repair or installation using OEM or manufacturer-approved parts when available and appropriate, rated for Florida attic temperatures that can exceed 130°F during peak summer heat. As an authorized Goodman dealer, Goodman installations follow Goodman's manufacturer installation guidelines.

08Step 8 of 8

Operational Verification and Documentation

Before we leave, we verify the system runs right: a 15–22°F temperature differential across the coil, refrigerant subcool and superheat against the manufacturer's target range, static pressure, and CFM airflow at the registers. You get documentation of the readings and the work performed.

Step 1 of 8

The Four Proof-Object Categories

Most contractors tell you they're experts. We show the work. During service calls - with the customer's permission - Tony and Jon Luke capture four kinds of proof objects that document what was wrong, what we measured, and what we fixed. These are the same captures other pages on this site point to when they reference "our diagnostic process." The examples described below are illustrative; real captured examples will be added as documented service-call photos are approved for use.

Category 1

Diagnostic Tool Captures

The instruments that turn a symptom into a diagnosis, photographed in use:

  • Digital manifold gauge readings - suction pressure, discharge pressure, superheat, and subcool
  • Multimeter readings - capacitor microfarad measurement, voltage at the contactor, amperage draw on the compressor or blower motor
  • Thermal camera images - temperature differentials across coils, ducts, and registers
  • Megohmmeter readings - compressor winding resistance
  • Combustion analyzer readings - for furnace and gas-heat work (secondary priority in Florida)

Category 2

Measurement Data

The numbers behind the diagnosis, recorded against manufacturer targets:

  • CFM airflow at the registers - measured before and after duct work
  • Indoor relative humidity (%RH) - recorded during indoor-air-quality assessments, with a 45–55% comfort range that helps keep indoor moisture in check and limits moisture-related equipment concerns
  • Temperature differential - return air vs. supply air, which should read 15–22°F on a properly operating system
  • Static pressure - measured across the air handler and across the filter
  • Refrigerant subcool and superheat - read against the manufacturer's target range for the specific system

Technician Checklists

The written checklists we work from, so nothing gets skipped:

  • Comprehensive AC maintenance checklist - the same one used during tune-ups
  • Pre-summer inspection checklist
  • Pre-hurricane preparation checklist - Florida-specific, ahead of storm season
  • Post-storm inspection checklist
  • New-install commissioning checklist

Repair Process Photos

Before-and-after photos of the actual repair:

  • Capacitor before/after - the failed unit's bulged top or burned terminals next to the new replacement
  • Coil cleaning before/after
  • Duct sealing before/after - with mastic applied at the joints
  • Drain-line clearing - the Florida condensate algae that blocks the line, cleared
  • Refrigerant recovery setup - refrigerant recovered per EPA Section 608, never vented

How We Document Your Service

The proof objects above are captured during real service calls, and we handle them carefully. Before capturing photos for your service record or for use on this website, we ask for your permission, and we avoid showing names, addresses, account numbers, or identifiable property unless you approve it. Anything that could identify your property - an interior shot, a house number, or paperwork - is redacted or left out. Phone-camera quality is fine; the point is the record, not the production value. You benefit directly: you see the measured fault, the part that was installed, and the verified result, so the diagnosis is something you can check rather than something you have to take on faith.

Schedule same-day AC service

System down today?

The same eight steps start the moment you call. Tony or Jon Luke can diagnose the fault, show you the readings, and in most cases fix it the same day during business hours. Call (407) 929-3535 to request same-day scheduling for AC repair, or set up twice-yearly AC maintenance to keep the weak parts caught before summer finds them.
