Next Hvac

Next Hvac operates as a locally owned heating and cooling contractor in Waxhaw, North Carolina, with an unblemished 5-star average drawn from 236 client reviews. Owner Siarhei Buidak leads a crew that keeps phones answered and trucks rolling around the clock, seven days a week, every day of the year. The company serves Waxhaw alongside neighboring Union County communities, tackling everything from failing thermostats to full-system replacements for homeowners who have been cycling through one call-in contractor after another.

What separates Next Hvac from the field is the combination of continuous availability and a methodical diagnostic approach. Siarhei Buidak has been described by clients as a technician who opens the outdoor unit in front of the customer, displays live temperature and charge readings on his electrical test gadgets, and confirms findings with an electronic leak detector before quoting any repair. The company handles both heating and cooling systems, covering heat pumps, central air conditioning, and water heaters without routing calls to a dispatcher or a third-party subcontractor.

During the Thanksgiving holiday, Yoke Chung's heating system failed entirely. A same-day visit from the Next Hvac crew revealed a cracked heat exchanger in the heater and an air conditioner near the end of its service life, leading to a full dual-system replacement that the owner managed from estimation through final installation. Samantha Lackey called in the morning after her thermostat stopped communicating with her downstairs zone and had a technician at her door the same evening, resolving the issue in under two hours and leaving her heated space fully operational. Reviewers across the board specifically name owner Siarhei Buidak for his technical precision and his habit of showing customers video evidence of what he finds inside their equipment.
