Recent Transformations

Upstairs AC System Replaced in a Cypress Two-Story

BeforeAfter

The problem: a 16-year-old Carrier condenser that had lost its charge twice in one summer. The homeowner was nursing it along with refrigerant top-offs, but the coil had developed multiple pin-hole leaks. We quoted a full system replacement with a written price, set a firm install date, and removed the old unit the same morning. The result: a correctly sized system with factory-matched indoor and outdoor components, proper nitrogen purging during brazing, and a subcooling reading within manufacturer spec. No more chasing leaks.

Furnace Heat Exchanger Failure in Katy

BeforeAfter

A routine tune-up turned serious when our technician pulled the blower assembly and found a visible crack across the secondary heat exchanger. That’s a carbon monoxide risk, not a repair-and-wait situation. We shut the furnace down at the gas valve, showed the homeowner the crack on camera, and presented options the same day. They chose a replacement. The new system went in two days later, and the final combustion analysis confirmed proper draft and zero CO at the register. The 365-Day Done Right Promise applied to the entire install.

AC Condenser Overheating in Bellaire

BeforeAfter

The unit would start, run for 20 minutes, and trip the breaker. We found a dual run capacitor bulged at the seams and a compressor pulling locked-rotor amps. The fix: a new capacitor and a hard-start kit, followed by a full refrigerant check. Total cost was under $300, parts and labor included. The compressor came back to life and the amp draw dropped to the manufacturer’s listed rating. This is the kind of repair that often gets misdiagnosed as a full compressor failure, which would have cost the homeowner thousands more.

Ductwork Reseal in a 1978 Energy Corridor Home

The homeowner said the back bedrooms never cooled, even after a new AC install by another company. We found flex duct that had pulled loose from two supply plenum collars, dumping conditioned air straight into the attic. The attic was 140 degrees in July. We reconnected the collars, sealed every joint with mastic, and re-insulated the connections. Static pressure dropped, airflow balanced, and the back bedrooms finally matched the thermostat setting. This is why we inspect ductwork on every call, not just the equipment.

Clogged Condensate Drain Flooding a Utility Room in Pearland

Water damage is a common Houston problem because our humidity loads mean the evaporator coil produces gallons of condensate every day. This line was packed with algae and sludge, so the pan filled and spilled onto the utility room floor. We cleared the drain with nitrogen, flushed the line, and installed a new float switch that shuts the system off if the line ever backs up again. Total cost: under $180. The written guarantee covered the repair for 365 days, as it does every repair we make.

Full AC and Furnace Replacement in Kingwood

This house had a patchwork system: an old Goodman furnace paired with a 2010 outdoor unit that had never been installed correctly. The cased coil was the wrong width, the drain pan was pitched backward, and the return drop was undersized. We quoted a complete system replacement under The Kingswell Way: written price before any work, a firm install date, and everything in writing. The result is a correctly matched Trane system with proper airflow, a level drain pan, and a subcooling reading the manufacturer would sign off on. This is what a real installation looks like when it’s done by someone trained on nine major brands.
