Recent Transformations

AC Repair: Dead Compressor, Milton Avenue

BeforeAfter

The problem: a Carrier unit that ran but pushed warm air. Homeowner had already been told by another company the whole condenser needed replacing. We found the run capacitor had failed and the coil was so packed with pollen and pine needles that the head pressure was through the roof. What we did: replaced the capacitor, washed the coil, and checked the refrigerant charge. The result: cold air at the vents that same afternoon, total bill under $300 instead of a $4,000 replacement.

Furnace Repair: Short Cycling in a Goodman, Windward

BeforeAfter

In Windward, a Goodman furnace would light, run for ninety seconds, and shut down. The homeowner was convinced the control board was failing. The actual culprit was a flame sensor coated in carbon buildup from years of use, sending the board a false “no flame” signal. We pulled it, cleaned it with a non-abrasive pad, and measured the microamp signal before and after. The furnace ran steady for a full cycle, and the repair carried our written one-year guarantee. Most furnace repairs like this run $150 to $450 depending on the part, and this one was nowhere near the top of that range.

Heat Pump Installation: Straight AC to Heat Pump, Crabapple

BeforeAfter

The before: a 2009 Lennox straight-cool AC paired with an electric furnace that made winter bills painful. The homeowner wanted one system that did both jobs. We installed a Daikin heat pump sized by a manual load calculation, not a guess from the old unit’s nameplate. New copper line set, new pad, new thermostat, and a condensate drain with a safety switch. The result: one system for cooling and heating, and Georgia Power rebate paperwork handled on the install date.

AC Repair: Frozen Evaporator Coil, Downtown Alpharetta

We got the call on a July afternoon when the indoor unit looked like an ice block. The system was low on refrigerant, most likely from a slow leak at the Schrader valve. We thawed the coil with the fan running, replaced the valve core, pressure-tested with nitrogen, and pulled a proper vacuum. Then we did a refrigerant recharge, which is topping off the cooling fluid your system needs to reach set temperature. The unit ran a full cycle and held. That repair was guaranteed in writing for a full year. If it fails in that time, we return at no charge.

Furnace Repair: Inducer Motor Failure, Roswell Border

A Trane furnace near the Roswell border was locked out on pressure switch errors. The inducer motor had seized, which is common on units that run hard through cold snaps and then sit through Georgia’s wet springs. We replaced the inducer assembly, checked the pressure switch tubing for cracks, and verified the flue was drafting properly. The new motor came with a one-year parts warranty, and our labor was covered by the same written guarantee as every repair we do.

AC Tune-Up: Fifteen-Year-Old Rheem, Haynes Manor

This Rheem had gone three years without service. The capacitor was reading 28 percent below spec, the coil was suffocating, and the condensate line was slow. We tested every electrical connection, cleaned the coil and drain line from end to end, and replaced the weak capacitor before it failed mid-summer. The homeowner got a written report with photos and readings. That is what maintenance should look like: facts on paper, not a checklist you never see.
