I hope I am following the rules in this post. I am currently living in Vegas. The motor went out on our condenser unit this summer (of course while I am deployed to the Middle East). We were able to get it fixed but would like to replace the AC system this winter as the system we have now is almost 12 years old and is already making a wierd noise again. I have been doing a lot of research on heat pump systems. Would this be a good way to go with the Vegas climate? If not, what kind of setup should I go with (I am not looking at DIY)?My main concern is energy conservation. Also, what is a price range that I should expect to pay? I am guessing between 6k-10k. Our house is 1300 single story. I understand that I need to have a contractor come out and run a few tests to see what size of unit I need but I am guessing it should be between a 2.5 and 3 ton unit. We currently have a gas furnace which I am guessing would need to be replaced with an air handler if I go with a heat pump. Thanks for the help.
