Why Active Heating
for your Heating Services?

For over 40 years, Active Heating has been providing heating services to the Watertown and Brookings, SD areas. We provide the highest quality service through our licensed and bonded HVAC technicians. Whether you need a new furnace for your home or need repairs on your existing unit, we are prepared to tackle your heating needs!

Choosing the Right Furnace


When your furnace no longer heats like it used to, your biggest decision will be to repair or replace. Even when a furnace is well-maintained, it will gradually become less efficient each year. Additionally, the average lifespan of a furnace is 15 years, so if your furnace is over 10 years old it maybe more cost-efficient to replace it. ​

Our technicians will thoroughly assess your home to determine exactly what you require. We'll measure your total floor space, perform ductwork analysis and discuss your family's comfort level. This is to ensure your furnace is properly sized for peak performance. 

Furnace Repair

No one wants to come home after a long day or work to a freezing house. Start thinking about furnace repair and maintenance in the fall before the temperatures start to drop. When you turn your furnace on and notice any of the following symptoms, it's time to Get Active:

  • Lack of airflow from your registers

  • Water pooling around your unit

  • Audible noises or hissing from your unit

  • Under-performing heat capacity
