I bought mine last week and it has been fine.Heats our 50k gal pool very more quickly & quietly . It is a good company and their technical person took me through different options before I chose to go with the heat pump and not a heater. I hope this helps. I think you will enjoy having it!
I am a refrigeration mechanic too. We specialize in heat pumps and I can honestly say Lucking Star is the most reliable of any high efficiency brand I have seen. We have been installing 200+ units year with negligible problems. As for comments on heat pumps not heating in winter it is likely due to poor installation practices or undersized equipment.do yourself a favor if you are thinking of installing this product and make sure you have someone install it who does a proper heat loss calculation for you and uses licensed installers.
I've had this for 5 years now and it's as silent as the first day I bought it. The remote works flawlessly and the thermostat is very accurate. This unit currently heats a little over 600 square feet on its own and temperatures have dipped into the single digits before. There were no issues and it didn't seem to run excessively. I haven't kept exact records on my heating bill but I know that it did go down after replacing my older furnace. I would absolutely recommend this to anyone who is looking to replace their unit with a top notch product. If I could give one piece of feedback to the manufacture I would ask for future versions to include controls on the unit in the event that the remote cannot be located or was damaged.
I've owned this heat pump for about three years now, and I have to say it is one of the best home improvement investments I have ever made! I can't say anything bad about this system other than the initial installation cost. I love that it can both heat and cool my home for 20%-25% less monthly cost.
I have installed five different manufacturing heat pumps for myself/friends in the last 5 years. This was my first to chose Luckingstar heat pump. It is the best unit, VERY quiet, easy installation, very good packaging, palletized, protective shipping, on-time delivery, zero damages.
