HVAC Before & After in Atlanta, GA

Photos beat adjectives every time. You can read that we install clean duct runs and level condenser pads until your eyes glaze over, but a picture of a rusted-out 1993 Trane next to the Carrier that replaced it tells the story in two seconds. This page is the visual record of what we actually do on the job. No stock photos. No staging. Just work we’ve done around Atlanta and the neighborhoods we serve.

AC Repair: Failed Compressor in a Buckhead High-Rise Condo

BeforeAfter

The homeowner called us on a Tuesday because their unit was running but blowing warm air. Our technician opened the condenser and found the compressor had shorted to ground after years of hard Atlanta summers. Before: a heat-damaged, locked-up compressor with scorched wiring at the terminal block. What we did: recovered the remaining refrigerant, pulled the old compressor, replaced it along with the filter drier and contactor, pressure-tested the line set, and recharged to manufacturer spec. The result: an AC system cooling to a 17-degree temperature split by late afternoon. That repair carries our 365-Day Done Right Promise in writing, not just a handshake.

Furnace Repair: Cracked Heat Exchanger in Decatur

BeforeAfter

This one came to us after another company red-tagged the furnace for a suspected crack. Before: a 2002 Rheem 80% furnace with a visible hairline crack along the second cell weld and some rust pitting from years of condensation. We pulled the heat exchanger and confirmed the failure. What we did: installed a new OEM heat exchanger, replaced the rollout switch and flame sensor as a precaution, and ran a full combustion analysis to verify safe CO levels. The result: the furnace fired clean, the draft reading came back within spec, and the family had heat that night. Victor’s line after this one: “That furnace was heating the attic more than the house.”

AC Installation: Full System Swap in Grant Park

BeforeAfter

An older Grant Park bungalow still had a 1998 Goodman R-22 system limping along. Before: a rusty condenser with corroded fins, a mismatched evaporator coil that had been patched together over the years, and duct leakage around the plenum connections. What we did: removed the entire old system, installed a new Trane 16 SEER heat pump matched to a new evaporator coil, sealed the plenum connections with mastic, leveled the new condenser on a composite pad, and added a new drain pan with a float switch. The result: electrical use dropped noticeably the first month, the home holds a steady temperature, and the written price we gave before the first tool came out matched the final invoice to the dollar.

AC Repair: Refrigerant Leak in a Sandy Springs Split-Level

The homeowner noticed ice on the copper line at the condenser, which is never a good sign in a Sandy Springs summer. Before: we found an evaporator coil leaking at the hairpin bends, with R-410A pressures down 40% from where they should be. What we did: isolated the leak point, recovered the refrigerant that remained, replaced the evaporator coil under warranty from the manufacturer, installed a new drier, pulled a deep vacuum, and recharged by weight, not by guesswork. The result: no more ice, a clean 20-degree split at the plenum, and a homeowner who now understands what a refrigerant recharge (topping off the cooling fluid your AC needs to run) actually means.

Furnace Repair: Ignitor Failure in East Atlanta

Before: a Carrier 90% furnace from 2009 that would start the draft motor, wait, then shut off without lighting. A homeowner with a cold house and no idea why. We tested the sequence of operation and found the hot surface ignitor had a hairline crack you could barely see. What we did: replaced the ignitor with an OEM part, cleaned the flame sensor, checked the pressure switch tubing, and verified the full startup cycle five times in a row. Most furnace ignitor replacements like this one run $150 to $280, parts and labor included. The result: heat in the East Atlanta house within two hours of the call, and a written guarantee on the repair for 365 days. If it fails again within that window, we come back and fix it at no charge.

AC Installation: Ductwork Correction and System Replacement in Midtown

This Midtown condo had a new-ish condenser someone had slapped onto old, mismatched equipment and a return duct kinked behind a wall. Before: the system ran constantly from April to October and barely held 80 degrees on a 95-degree Atlanta day. What we did: pulled the kinked duct section and re-ran it with smooth hard pipe where possible, installed a properly sized Lennox condenser with a matching air handler, and added a media filter cabinet the homeowner had never had. The result: the same square footage now cools to 72 degrees with shorter run cycles. A kinked return duct is the HVAC equivalent of trying to breathe through a straw, and fixing it changed the entire feel of the unit.
