Garage AC Unit Buried in Lint and Drywall Dust

BeforeAfter

The homeowner’s AC ran constantly but struggled to hold 78 degrees during a West Covina heat spell. We found the evaporator coil matted with a gray paste of lint, drywall dust, and pet hair, which was choking airflow. Our tech pulled the blower wheel, washed the coil with a non-acidic cleaner, and sealed a leaking duct collar right above the unit. The result was a 19-degree temperature drop across the coil and a garage that finally cooled down. It was a $340 repair that saved the homeowner from a compressor replacement quote they’d gotten elsewhere.

Furnace Swapping Out a Cracked Heat Exchanger

BeforeAfter

A family off Workman Avenue called us because their carbon monoxide detector had tripped twice in one winter. We scoped the heat exchanger with a camera and found a hairline crack that opened up when the furnace got hot. We replaced the exchanger, inspected the flue, and verified the gas manifold pressure with a digital manometer. Furnace maintenance is a safety issue, not just a comfort one, and we don’t patch or bend the rules on combustion parts. The furnace was back to safe operation same day, backed by our written repair guarantee.

Condenser Swap After a Dog Chewed Through the Control Wiring

BeforeAfter

If you have a dog that likes to dig, you already know where this one is going. A family’s German Shepherd chewed the low-voltage control wire running along the side of the house to the condenser, which took out the whole cooling system. We ran new 18-gauge thermostat wire through flexible armor, relocated it up off the ground, and added an inline fuse to protect the control board. The job took about two hours, which was faster than the homeowner expected given they’d been told by another company it meant a whole new unit.

Attic Furnace Burying the Filter in Blown Insulation

A homeowner in the Shadow Oak area hadn’t changed their furnace filter in four years because the filter slot in the attic was buried under sixteen inches of blown-in insulation. Every service call became an hour of shoveling before anyone could even look at the unit. We built a small plywood platform around the furnace, relocated the filter slot to an accessible side panel, and left the homeowner a marked path from the attic hatch. Now the filter change takes five minutes, not an excavation. This is the kind of fix that doesn’t show up in a spec sheet, but it changes how the system runs for years.

AC Install After a Rooftop Unit Finally Gave Out

A 2006 Goodman package unit on a flat-roof home near Sunset Square finally cooked itself after a run capacitor failed and the compressor overheated during a July heat wave. The homeowner weighed repair against replacement and chose to replace with a new 3-ton unit rather than sink another cost into a 17-year-old system. We lifted the old unit off with a crane, set the new one, sealed the curb, and ran the full startup checklist before leaving. New units get a set install date and a written fixed price before any work begins, never a surprise add-on at the door.

Air Handler Drowning the Closet from a Blocked Condensate Line

The homeowner found water pooling in a hallway closet where the air handler sits, right in the middle of a 100-degree weekend. The condensate line had never been cleaned, and the sludge buildup plus a sag in the PVC meant water backed up until it overflowed the drip pan. We cut out the sagged section, blew the line clear with compressed air, and installed a float switch that kills the unit if water ever backs up again. That float switch is a cheap insurance policy against a soaked ceiling and a mold situation in a West Covina closet.
