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
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
Upgrading to the Apollo air-to-water heat pump was the best decision for our home. It integrated perfectly with our existing radiant floor heating. It runs quietly outside and provides perfectly even, comfortable heat inside
You can tell just by looking at the Apollo unit that it's built to last. It handles the elements outside without a problem and operates surprisingly quietly. It gives us total peace of mind knowing we have such a dependable system
