Guelzow Heating & Air Conditioning

Guelzow Heating & Air Conditioning serves Wisconsin Rapids as a round-the-clock HVAC contractor with a 4.8-star rating drawn from 116 client reviews. Their team provides furnace and air conditioning repair, new system installation, and water heater services to residential customers throughout the area. The business maintains 24-hour availability every day of the week, ensuring homeowners can reach them whenever heating or cooling emergencies arise.

What distinguishes Guelzow from other contractors is their emphasis on rapid response and transparent communication. Multiple reviewers specifically mentioned same-day service for urgent situations, with technicians arriving earlier than scheduled and completing installations within days of the initial call. The team takes time to explain system operations and walk homeowners through thermostat setup, a detail several customers highlighted as refreshing compared to past experiences with other service providers.

Customers repeatedly named technicians who handled specific situations with notable skill. Rebecca mentioned the team accommodated her within 72 hours during an arctic blast, arriving early and completing a thorough gas water heater replacement. Another reviewer described how Joe and a coworker arrived the same day when a furnace failed, then installed a new unit within two days while explaining each step. Luke praised the crew for clear communication, thorough cleanup, and testing every faucet to confirm no air remained in water lines after his heater replacement.
