Abacus Plumbing, Air Conditioning, & Electrical

Abacus Plumbing, Air Conditioning, & Electrical has served the Greater Houston area for over two decades, earning a 4.7-star rating from more than 11,700 reviews. This multi-trade contractor holds state licenses in plumbing, HVAC, and electrical contracting, offering residents of Houston and surrounding communities a single point of contact for home comfort emergencies. The company operates around the clock, every day of the year, handling everything from slab leak detection to AC compressor failures to electrical panel upgrades.

This contractor distinguishes itself through manufacturer-specific expertise and lifetime workmanship guarantees. As a Lennox dealer, they install and service residential heating and cooling systems using OEM parts, and they back their installations with a lifetime warranty covering both labor and materials. Their VIP Maintenance program offers annual tune-ups across all three trades, including priority scheduling and discounts on repairs. For indoor air quality, they install REME HALO purification systems and perform professional air duct cleaning using negative-pressure equipment.

Customer reviews document specific technician encounters that illustrate the company's service approach. One reviewer described a same-day heat wave call where technician Andre diagnosed a failing capacitor in under 20 minutes, avoiding an unnecessary compressor replacement. Another reviewer documented a holiday weekend emergency where a cracked heat exchanger required immediate replacement, with the technician coordinating parts delivery through a supplier network. However, multiple negative reviews cite concerns about pricing transparency and diagnostic recommendations, with one reviewer alleging unnecessary part replacement and another describing a discrepancy between quoted repairs and final charges.
