Window World advertises on The Ticket for $269 a hole for vinyl low e windows, if I remember correctly. Then you’ll have to find someone to put them in.
I had a carpernter working on another project at my house and in passing I told him I was also going to have windows installed and he said he would do it for $125/window.
No idea if that’s the going rate, or not.
Window World is popular bc they advertise all over the place, but they're not your best option IMO. Out where you are I'd recommend going to a McCoy's store to find your windows. The company I worked for was Atrium and was merged with PlyGem last year. Those windows can be bought in Lowe's stores under the Reliabilt brand or at McCoy's under the Atrium brand. PlyGem windows can be bought in Home Depot. After the merger they're the single largest window manufacturer in North America, not that it helps you get better windows.
I recommend McCoy's bc their service offering sounds like the best among all of our customers. You'll get better answers to your questions in the store and also the best deal on installation.
SnoSki may not benefit from McCoy's as they're generally out in more rural areas, but there are other options available in the city.
$125 a window for installation is a pretty good price. I put new windows in my dads house several years ago for Father's Day and our service technicians charged me $100 per window and that included disposal of old ones. That's a good old boy discount so if you have someone who isn't a buddy quoting $125 a hole I'd take it.
On quality...
The glass coating and spacer are the two biggest factors in energy savings. The amount of benefit from various LoE coatings can be significant. LoE SC is the most common coating in Texas for Guardian Glass and LoE 270 is the most common for Cardinal Glass. There's essentially no difference between the two so don't get hung up on either of those.
LoE 366 is a premium coating from Cardinal that is very impressive. I've seen demos (science fair type displays) of the amount of energy transfer it blocks and it's remarkable. If you want energy efficiency and can afford it I'd recommend it. If you're worried about the appearance of the windows more than energy cost savings you may not like it. It's a darker blue color from the street and some home owners don't like it. Builders don't like it much due to cost.
As I alluded to, the energy savings is excellent with it. LoE 270 and SC are pretty good about keeping heat out, but they allow some heat transfer out compared with 366. The 366 coating allows virtually nothing in or out.
The window series quality is something difficult to determine at purchase and the outlet you buy from may not even know much warranty detail on them either. I'd definitely try to get that, though. Design has a lot to do with how easy it is to build quality windows and how easy it is to screw up a window in the manufacturing process. At Atrium our 130 series was very popular and tended to have more warranty issues. A comparable window was the 8100 series and it had far fewer warranty issues at virtually the same price point and performance level. I put 8100 series windows in my dad's house, FWIW. The 130 series was popular with customers bc it had a lot more options available, (painted colors, bronze and black laminate, flange or no flange, replacement or new construction, etc. The 8100 was a premium single hung window for replacement only and was offered in white, clay, or almond colors only. That said, due to the variety of options they tried to design into the 130 series it became exceedingly difficult to manufacture without various quality issues. Since the 8100 came in only 3 colors with no variations it was simple to manufacture with high quality.
PlyGem was a massive window company, but they captured their market share by undercutting everyone on price. Their quality leaves a lot to be desired, though the new plant manager (my old boss) in the Dallas plant has already made big strides with their quality processes with the HD windows made there.
Double hung windows are a personal preference. You pay a lot for them and they're great to have, but my personal preference is that they aren't worth the money.
I've got more, but I think that's enough on mobile for now and I'm not real sure what all I've covered and omitted at this point. If you want more info or have more questions feel free to call me. I think I gave you my number once.
