Holtkamp HVAC & Plumbing

Holtkamp HVAC & Plumbing has served Suwanee residents for more than two and a half decades, building a track record that shows up in their 1,087 reviews earning a near-perfect 4.9-star rating. The company operates under license number and employs technicians who handle both residential comfort systems and plumbing infrastructure across Gwinnett County, including nearby Sugar Hill and Buford. Their service hours run Monday through Friday 7 AM to 7 PM, with Saturday availability from 9 AM to 2 PM, and around-the-clock emergency response for situations that cannot wait until morning.

What distinguishes Holtkamp from neighboring contractors is their dual-trade capability under one roof, meaning a single service call addresses both climate control and plumbing rather than coordinate separate companies. The company carries Lennox, Carrier, and Mitsubishi equipment for residential and light commercial applications, and their indoor air quality offerings include REME HALO purification and proper duct sealing rather than basic filters. They handle water heater replacements, gas line installation, bathroom remodels, and irrigation trenching alongside HVAC work, giving homeowners a single point of contact for multiple underlying systems.

Reviewers repeatedly name specific technicians who handled their situations. Hunter Phillips resolved multiple unique faucet repairs for one homeowner by ordering parts same-day rather than scheduling return visits, while Nick Nastasia spent extra time explaining system operation and maintenance suggestions after completing heater service. Another reviewer noted Kevin performed fall furnace preparation before winter weather arrived, and long-term customers mention Mathew Holtkamp himself has maintained their systems for over twenty-five years.
