Had a few windows installed. They were installed promptly and correctly.The price was fair and easy to arrange financing.There were some issues about fixing some pre existing problems around my window frame that I was disapponted weren't addressed. I recommend getting things in writing as is always prudent.Update: the folks at Koehler did work with me to continue to resolve my issues, things were good after some amount of time due to an atypical situation.I will revise my score on this basis.

I had a BIG window project done (over 30 windows) by Koehler in the summer of 2021.Overall I have to give this company 5 stars. Not only did they have one of the most competitive window rates (and we shopped around), but they sell solid products. We had the Simonton Reflections 5500s installed and I waited 6+ months to see how they performed before writing up this review.First, the salesmen: good, on time, no pressure (no commission), and knowledgeable. Solid. Owner even came out to meet with me after talking with sales guy when I had concerns and further questions about the project. They make time for you.Next, the customer experience: I am a very thorough researcher and DIYer. I actually asked the company to sell me an upgraded triple pane version of the window. I got a phone call where one of the owners said "look I can sell it to you and charge you more, but it's just not worth it. Double pane is more than enough, check out the energy numbers on Simonton's website." This company literally TALKED ME OUT OF AN UPSELL. And in the end they were totally right. Double pane is holding up beautifully. Six stars.Install: super efficient and pro crew. 2 guys did 30+ windows in 2.5 days. No major damage to the home (they did dent some door trim, big deal, stuff happens, I patched it in minutes when they were done). They were quick to resolve and address issues. They even went above and beyond and covered these old weird aluminum pipes we had in our windows (which are load-bearing) with some nice PVC trim. Really made the whole house pop. I would give the install crew 4 stars because while they kicked butt and did a great job, one of the dudes was kind of gruff. I didn't really love interacting with him or his overall demeanor. He seemed pretty unhappy, but maybe he was having a bad week or something, who knows. The other guy who seemed to be "the leader" was terrific all around. 4 stars here.Let's talk energy savings. We upgraded from 1970s aluminum windows that were super leaky to these Simonton 5500s and wow. AC runs like 1/3 as much in summer. Heat runs 1/3 as much in winter. House is way more comfortable at all times, humidity is well-controlled, and bugs don't litter our window sills anymore. Measurements for window fitting were also spot-on, no issues.Overall great company, did a super good job of a difficult project for a tough customer. 5 stars for sure, don't hesitate to hire and work with the Koehler gang for window issues. Speaking of which, literally 0 issues since install. No creaking or rattling or expansion / contraction noises, no cracks or chips, no problems. Excellent.
