It's been about a month now since KJ's installed dual AC units at my house (along with the advertised free attic fan, which is amazing BTW). This company gets an A+ for everything. I am totally satisfied with my new AC and its has made this summer in the IE so much more enjoyable. I requested a competitor to come out and give us an estimate and we were getting the run-a-round with postponing the appointment, so we called KJ's and they were out the very next day, which was a Friday, I believe. My AC units just couldn't keep up with the summer heat and my upstairs unit was on all the time. They suggested that I replaced the units since they were about 15 years old and my sprinklers were giving them some water damage. They were out the very next business day, which was Monday and installed them without any major hiccups. I was having some condensation issues from the piping that the original builders made, so KJ's fixed that up for me as well and did a thorough check on my ducts. I would recommend them to anyone. Their service is second to none.
