the dif, is only that a straight ac works in one direction. Meaning it works in cool mode, to remove heat/humidity from the air in summer. The heat pump works both directions, meaning it does the same thing as the ac in summer, but in the winter it reverses and can instead of removing heat in summer, can add it to the house in winter for heating. its like throwing ac in reverse (Its not like it is) the heat pump can take advantage in mild climates by doing this, below a certain temp, usually a aux heat system electric, or gas heating takes over
if you have more questions on this just reply and i will reply back, thanks gary
Are heat pump systems more efficient than a regular ac. And, are they the ones that you have to run a sprinkler because it uses water?
We are in NE Florida and even though the past 2 winters have been no lower than 25 degrees at times, we have had very cold winters down to 17 - 19, for a few days at a time. Will the heat pump work for us.
Lastly, Are they more expensive than a regular ac?
Gotcha. The unit we are replacing was a 10 seer 3 1/2 ton. The home is 2200 Sq ft. We are trying to decide if the duct work can handle a 14 seer 4 ton unit. It is a mobile home. Your advice?
