Black-Haak Heating | Licensed HVAC Services in Greenville, WI

Our maintenance service is designed to keep your system running efficiently and reliably through Greenville's changing seasons. It includes a thorough inspection, cleaning of critical components, checking refrigerant levels, testing safety controls, and ensuring proper airflow. A key part of our service is proactively addressing common local issues like clogged condensate drains, which can cause water damage and affect humidity control. Regular maintenance helps improve indoor air quality, prevents unexpected breakdowns, and can extend the life of your system.

Our technicians will perform a detailed assessment of your system's age, efficiency, repair history, and performance. We consider factors like frequent repairs, rising energy bills, uneven heating or cooling, and whether the system uses outdated refrigerants. For a family-owned company that's been here since 1956, our goal is to provide honest, transparent advice. If a repair makes sense and is cost-effective, we'll recommend that. If your system is old, inefficient, and costing you more in the long run, we'll explain the benefits of a replacement with clear, flat-rate pricing options.

Yes, we do. As a licensed heating, cooling, electrical, and plumbing contractor, Black-Haak Heating manages the entire installation process. This means our own skilled technicians handle connecting the new unit to your home's electrical system and any necessary plumbing, such as for condensate drainage or water-source systems. Providing all these services under one roof ensures the job is done cohesively, efficiently, and to our high safety standards, giving you a single point of contact and responsibility for your complete comfort system.
