Many are now being installed because they are the most efficient, give you the best comfort and qualify for federal tax credits. That said, always go with a company who is certified with a specific manufacturer. For example, Sunshine is an authorized Carrier dealer who is large enough to stock parts and has trained staff and the equipment for all these newer systems where as a small company installer who might not have the resources to install and service these newer systems will most likely convince you to get another single stage heat pump because they are the cheapest and the easiest to work on but they will be the least efficient and cost you more money to run them in the long term. Don't be afraid of newer technology since at some point it will be common place. Who ever thought years ago we would have so many computers running our cars? If we didn't advance in auto technology we would still be driving 1965 Chevies that were simple and easy to fix but costly to operate in today's world. Same thing with most technologies.

I would point out that single stage compressor units will also qualify for the Federal tax credits, based on the SEER rating. A variable speed system will cost about 50 to 70 percent more than a single stage system. You will never recover that initial cost with electricity savings. As far as availability of parts, I think that there are so many Carrier single stage units in The Villages, that a large Carrier dealer can probably get the needed parts without even needing to order them. The poster who was waiting for 4 months needed a proprietary circuit board for a specific variable speed compressor. I doubt that any dealer would keep something like that in stock.
One other thing. When your house needs to be cooled, do you really want the compressor to run slower? Other than a possible humidity benefit, I want the compressor to run at full speed and cool down my house. Also, a variable speed compressor is only more efficient if it is programmed correctly, and serviced periodically.
