I recently got my new Apollo 5-ton air-to-water heat pump installed, and it came out real nice. It's real nice and has a real nice look to it. I am very impressed with the finish of this unit; everything's neat, everything's dressed, it's all clean, painted, airtight, and dry. It's also very quiet. The old unit used to sound like a rocket ship, and this unit is very quiet. I'm very happy with my unit so far. We've gotten down into the 30s, and this thing has no problem keeping up so far. I've noticed the air is hotter, so it doesn't come on for as long, and I'm thinking this is probably making a little hotter water, which is nice.
