Before & After Gallery - Brandt HVAC Co Dallas

HVAC Before & After in Dallas, TX

We could tell you we do clean work, but you’d be right to want proof. The photos below are the kind of jobs our techs see every week across Dallas: rusted-out condenser coils, furnace heat exchangers with hairline cracks, drain pans that have been leaking into drywall for months. Most of these systems weren’t installed badly. They were just old, under-serviced, or patched together by someone in a hurry years ago. The before-and-after difference is what a careful repair or replacement actually looks like when nobody’s cutting corners. Devin Marlowe is the owner here, and he reviews every major job we photograph for this page. You’ll see exactly how we leave a mechanical room or an outdoor unit: clean, level, labeled, and ready for a Texas summer.

AC Repair: Dead Condenser Fan Motor in Lake Highlands

BeforeAfter

This Carrier unit in Lake Highlands shut down on a 104° afternoon because the condenser fan motor seized. Before: the fan wouldn’t spin, the compressor was cycling off on thermal overload, and the coil fins were packed with cottonwood. We replaced the motor and run capacitor, washed the coil, and checked the refrigerant charge. After: the unit pulled the house down from 86° to 74° in about ninety minutes.

Furnace Repair: Cracked Heat Exchanger in North Dallas

BeforeAfter

During a fall tune-up on a 14-year-old Trane furnace, our tech’s inspection camera found a stress crack in the secondary heat exchanger. Before: the unit was still running, but that crack was a carbon monoxide risk we wouldn’t let slide. We red-tagged the furnace, sourced the replacement part, and had heat back on the next day. After: combustion readings came back clean, and the written guarantee covers the repair for 365 days, parts and labor.

AC Maintenance: Overheated Compressor in Oak Cliff

BeforeAfter

A Goodman unit in Oak Cliff ran constantly but couldn’t hold 78° once the afternoon sun hit the west wall. Before: the condenser coil looked like felt, and the compressor was pulling high amps and running hot. We did a full maintenance: coil wash, fin combing, capacitor test, and drain line flush. After: head pressure dropped 40 psi, the compressor amp draw fell within factory spec, and the owner’s July electric bill was $90 lower than June.

Furnace Repair: Failed Igniter in Plano

This Lennox furnace would light intermittently, then quit altogether on the first cold snap of the season. Before: the hot surface igniter had a hairline crack, so the gas valve would open but nothing would ignite. The homeowner had already replaced the thermostat, thinking that was the issue. We diagnosed it in about twenty minutes, replaced the igniter, and verified the flame sensor was reading correctly. After: three clean light-offs in a row, and the home hit its setpoint in under an hour. Most igniter jobs like this in Dallas run $150 – $300, parts and labor included, which is why we tell people not to guess at control-board failures first.

AC Repair: Refrigerant Leak in Mesquite

A Rheem system in Mesquite needed a refrigerant recharge (that means refilling the fluid that moves heat out of your home) every summer for two years running. Before: the evaporator coil had a pinhole leak that only showed up under high pressure. We located the leak with an electronic sniffer, quoted the coil replacement in writing before any work started, and had the job done same day. After: the system held its charge perfectly, and the coil now pulls condensate the way it should instead of dripping into the emergency pan.

AC Maintenance: Neglected Condensate Drain in Garland

This York system in Garland had been dripping into the emergency pan long enough to rust it through in one corner. Before: the primary condensate drain was completely blocked, so water was running down the side of the furnace and into the drywall below. We flushed the line, cleaned the pan, replaced the rusted sections, and installed a float switch that would kill the compressor if the line ever backed up again. After: a dry mechanical closet and a dry ceiling. The homeowner kept the old drain line, which had a half-inch of black sludge in it, as a souvenir for the next tech who tells him maintenance isn’t necessary.

Want Results Like These?

Every one of these jobs started with a phone call and ended with a written price and a written guarantee before any work began. If your AC or furnace is doing something it shouldn’t, call (325) 312-3269. A live person answers day or night, and we’ll send a background-checked, uniformed tech with a photo ID badge, so you know exactly who’s walking up to your door. That’s the Threshold Standard, and it’s on every visit.
