Recent Transformations

Carrier AC Replacement in Summerlin: From 22-Year-Old Unit to Variable-Speed Upgrade

The old Carrier rooftop unit had been cooling that Summerlin house since 2002. Compressor was pulling high amps, the condenser coil looked like a sand trap, and the homeowner had already spent $600 on refrigerant in two summers. We pulled the entire unit, set a new variable-speed Carrier in the same footprint, replaced the rusted curb adapter, and rewired the disconnect. The result: a 22-degree temperature drop at the vents on a 108-degree afternoon, and a utility bill that dropped by a third the first full month.

Furnace Heat Exchanger Swap in Summerlin North: Corroded Cell to Safe Heat

A homeowner in Summerlin North called because their CO detector kept chirping near the closet furnace. The heat exchanger had hairline cracks and surface rust, which is a carbon monoxide risk we treat as a no-run condition. We shut the gas, pulled the old exchanger, and installed a new sealed cell with fresh gaskets. Written guarantee on the repair is good for 365 days. The detector hasn’t chirped since.

AC Condenser Fan Motor Repair in Silverado Ranch: Locked Rotor to Full Airflow

This Silverado Ranch condenser had a fan motor that seized mid-rotation, which warped two blades and tripped the breaker. The outdoor unit was baking in afternoon sun, and the system was short-cycling. We replaced the motor, capacitor, and both damaged blades, then checked the refrigerant pressures to make sure the overheating hadn’t caused a secondary problem. Total repair came in at $340 parts and labor, and it was cooling again within three hours.

Full Ductwork Sealing in Summerlin: Leaking Attic Runs to Sealed, Balanced Airflow

The homeowner said the two back bedrooms in their Summerlin house never got cool, no matter what the thermostat read. We found a plenum joint that had pulled apart in the attic, dumping conditioned air into a 140-degree attic. We resealed every accessible joint with mastic, re-insulated the torn sections, and balanced the registers. The temperature difference between the living room and back bedrooms went from 11 degrees to 3 degrees.

Goodman AC Install in Silverado Ranch: Flooded Pad to Raised, Code-Compliant Set-Up

After two monsoon seasons, this Silverado Ranch condenser was sitting in a low spot that collected runoff, and the base pan had rusted through. We built a raised, level pad with proper drainage slope, set a new Goodman 14 SEER unit, and ran new copper lines because the old ones had corrosion at the flare fittings. Written price before we started: $6,850 installed, and the number did not change at the door.

AC Blower Wheel Cleaning in Summerlin: Dust-Clogged Cage to Clean, Quiet Airflow

A Summerlin homeowner complained that the AC ran constantly but the house felt humid, and there was a faint musty smell from the vents. The blower wheel in the air handler was caked with a half-inch of dust and lint, which cuts airflow dramatically and makes the system work harder. We pulled the blower, cleaned the wheel with a degreaser and hot water, and checked the evaporator coil. Airflow at the vents measured 35% higher after the cleaning, and the musty smell was gone within two days.
