I have a luxaire which is same as York. I have the lx series 14.5 seer heatpump.

I'm very happy with it. The middle-grade models like I have come with a compressor jacket, demand defrost, & upgraded cabinet.

They use copeland scroll compressor and have 10 year warranty on all parts.

I've been very happy with it. I've had mine for a year. I've used alot since mine is a heatpump.

I'm in NE ohio too. You should probably spend a bit more and get a heatpump. They heat very efficiently and cheaply when above freezing.

I have just replaced a York heat pump with a Trane. I did not have good experience with this York at all. Finally it was replaced only after 10 years in operation. I had 4 service calls. Last year, the AC did not work, the tech. came and injected freon. It worked for that Summer but last winter it ran most of the time on the emergency heat. In June, I called and the same tech. came. This time he injected freon and dye without saying anything. He told it should last thru. the Summer. Knowing there must be a leak in the system (coil), I asked how much to fix a leak. It's about $700. The coil has to be replaced and it is not readily available. The heat pump is 10 years old.

I sent an email to York company customer service asking about how to locate and fix a leak. Never get reply. Seemed a lousy company to buy a heat pump from.

I received quotes from Rheem, Trane and Carrier. Rheem seems a good one and it is rated well in the Consumer Report. I went with Trane since the dealer offers 12 months same as cash

I did a lot of research before replacing my old system and went with Trane. A big consideration was how much longer I was going to live in that house. Trane is a very good brand here in South Florida and was a big plus when we sold the house. Goodman/Rheem is a big seller too, but I was not too keen on Goodman. It seemed very noisy. I got ten bids and the prices could vary as much as 2k for the same system. Some bids did not want to replace the copper even if I went with the new r410. I picked a family company (father/son), R22, XR13 with variable speed air handler. No complaints except we sold the house 3 years earlier than I planned. (wife's idea). I would recommend Trane XR13/2 stage heat pump/variable speed air handler. The R410 vs R22 is up for discussion. The R22 is going away but the R410 is higher pressure. Make sure no matter what you pick they replace the copper. Copper was very expensive a few years ago, but it's is much cheaper now. York is not very popular here anymore.
You might qualify for the tax rebate depending on the SEER factor etc...I did not want to put alot of money into a system that I knew I was selling. I used the online programs to check the "pay back" and determined the XR-13 was good for me. One thing I did like was it is not as complex as some of the higher end Trane Systems. Trane is offering rebates here in some areas, plus the utility companies sometimes do too.

The key is all about the installation so that is why I called around. Even the "big name" contractors can take short cuts. It is a brutal business here in South Florida. The big name guy here was just too expensive (2k more) for the same package.

You really have to do your homework. Read up on it so you can ask the right questions. My contractor spent about 4-5 hours talking about options over two days. There are alot of different options.

Good Luck!
