Customer Success Stories
The Apollo heat pump system is very efficient, quiet, and easy to install. It stands out for its clear design, well-organized components, and advanced features like a touchscreen and remote monitoring through an app. It also allows precise temperature control and includes an electric backup for very cold conditions. Overall, it's a reliable and practical system.
Heats my home nicely and economically. The cold weather does not seem to affect the pump. Overall I'm very happy with the system. The techs have been very helpful whenever I have had questions regarding installation, etc.
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
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
