The 3 Series 300A11

Value & Performance
3 Series Decades of research

The 3 Series upholds the standards and the trust associated with the WaterFurnace name — and offers it all at a great value. The 300A11 benefits from technology that's been refined through more than 30 years of research, a long list of engineering advancements, and the best in manufacturing experience to provide the best comfort and efficiencies at an amazing price point.

Efficient operation
Dual Capacity for Amazing Efficiency

While traditional conditioning systems typically run at one speed, the 300A11 operates in two speeds — high and low for greater comfort and efficiency. It'll run most often in low speed to keep your home consistent and efficient but will switch over to high speed in instances where the home needs more conditioning than low speed can provide.

Heating & Cooling
One system for Heating & Cooling

The 3 Series 300A11 provides forced air heating, air conditioning, and even generates a portion of your home's hot water — all from a single interior unit. You'll experience a level of comfort and savings that's far greater than any ordinary system without traditional noisy outdoor equipment cluttering up your yard.

Comfortable from anywhere
