Customer Success Stories

Since installing the Apollo heat pump, our energy bills have plummeted. It pulls heat right out of the air outside, even when it's freezing, and uses a fraction of the electricity our old system did. It's incredibly efficient

Quote Icon

The Heat Pump is impressively quiet; I can hold a full conversation while standing just three feet away from it. Because it's a DC inverter unit, there are no hard starts—it just ramps up smoothly from a few watts. It even handled outdoor temperatures in the single digits without any issues.

I was skeptical about a heat pump in our cold climate, but the Apollo proved me wrong. It consistently delivers strong, comfortable heat to our entire home, even during the deepest winter freezes. It's a truly robust system
